In order to power entire communities with clean energy, such as solar and wind power, a reliable backup storage system is needed to provide energy when the sun isn’t shining and the wind doesn’t blow.

One possibility is to use any excess solar- and wind-based energy to charge solutions of chemicals that can subsequently be stored for use when sunshine and wind are scarce. At that time, the chemical solutions of opposite charge can be pumped across solid electrodes, thus creating an electron exchange that provides power to the electrical grid.

The key to this technology, called a redox flow battery , is finding chemicals that can not only “carry” sufficient charge, but also be stored without degrading for long periods, thereby maximizing power generation and minimizing the costs of replenishing the system.

University of Rochester researchers, working with colleagues at the University at Buffalo, believe they have found a promising compound that could transform the energy storage landscape.

In a paper published in Chemical Science, an open access journal of the Royal Society of Chemistry, researchers in the lab of Ellen Matson, assistant professor of chemistry, describe modifying a metal-oxide cluster, which has promising electroactive properties, so that it is nearly twice as effective as the unmodified cluster for electrochemical energy storage in a redox flow battery.

“Energy storage applications with polyoxometalates are pretty rare in the literature,” says lead author Lauren VanGelder, a third-year PhD student in Matson’s lab. “There are maybe one or two examples prior to ours, and they didn’t really maximize the potential of these systems.”

“This is really an untapped area of molecular development 💫,” adds Matson.

The cluster was first developed in the lab of German chemist Johann Spandl, and studied for its magnetic properties. Tests conducted by VanGelder showed that the compound could store charge in a redox flow battery, “but was not as stable as we had hoped.”

However, by making what Matson describes as “a simple molecular modification”— replacing the compound’s methanol-derived methoxide groups with ethanol-based ethoxide ligands—the team was able to expand the potential window during which the cluster was stable, doubling the amount of electrical energy that could be stored in the battery.

Says Matson: “What’s really cool about this work is the way we can generate the ethoxide and methoxide clusters by using methanol and ethanol. Both of these reagents are inexpensive, readily available and safe to use. The metal and oxygen atoms that compose the remainder of the cluster are earth-abundant elements. The straightforward, efficient synthesis of this system is a totally new direction in charge-carrier development that, we believe, will set a new standard in the field.”

The electrochemical testing required for this study involved equipment and techniques not previously used in the Matson lab. Hence the collaboration with Timothy Cook, assistant professor of chemistry at the University of Buffalo, and Anjula Kosswattaarachchi, a fourth-year graduate student in the Cook lab. VanGelder visited the Cook lab for training on testing equipment, and in turn helped Kosswattaarachchi with synthesizing compounds.

The two groups have applied for a National Science Foundation grant as part of an ongoing collaboration to further refine the clusters for use in commercial redox flow batteries.

Matson stressed the “crucial role” played by VanGelder, who conducted the initial testing and experiments on the clusters while Matson was on maternity leave. “As a third-year graduate student, she did an incredible job of starting this project. She’s played an important role in driving this research effort in the lab,” Matson says.

A University Furth Fund Award that Matson received last year enabled the lab to purchase electrochemical equipment needed for the study. Patrick Forrestal ’19 of the Matson lab also contributed to the study.

Tesla’s giant battery in Australia is already eating away at ‘gas 🦖 cartel’s’ profits, report says

We already reported on how Tesla’s giant battery in Australia made around $1 million in just a few days by taking advantage of the country’s volatile energy market.

But now a new report shows how it is also eating away at the ‘gas cartel’s’ profits.

Home Solar Power


When an issue happens or maintenance is required on the power grid in Australia, the Energy Market Operator calls for FCAS (frequency control and ancillary services) which consists of large and costly gas generators🦖 kicking in to compensate for the loss of power.

These services are so costly that it can sometimes amount to up to $7 million per day – or 10 times the regular value of the energy delivered.

Electricity rates can be seen reaching $14,000 per MW during those FCAS periods.

Now Renewecomy reports that FCAS were required on January 14, but the prices didn’t skyrocket to $14,000 per MW and they instead were maintained at around $270/MW after a short spike.

The bidding of Tesla’s 100MW/ 129MWh Powerpack project in South Australia on the services is credited with escaping the price hike, which would have cost energy generator and consumers millions in costs.

The Powerpack system is able to switch from charging to discharging in a fraction of a second, which allows Neoen, the operator of the system, to quickly respond when frequency issues happen.

Ed McManus, the CEO of Meridian Australia and Powershop Australia, told Renewecomy about the situation on the Energy Insiders podcast:

Quote
“If you look at FCAS … the costs traditionally in South Australia have been high …. and our costs in the last couple of years have gone from low five-figures annually to low six-figures annually. It’s a hell of a jump,”

“That plays into the thinking of new players looking to come into South Australia to challenge the incumbents. FCAS charges are on their minds.

“It’s a little early to tell, but it looks like from preliminary data looks that the Tesla big battery is having an impact on FCAS costs, bringing them down … that is a very, very significant development for generation investment and generation competition in South Australia.

“The South Australian government deserves a big pat on the back …. they have received a fair bit of flack – people saying if the power goes out, the battery can only power state for 5 minutes – but that is kind of irrelevant.

“The battery is there to do other things … and it looks like it has been phenomenally successful in doing that.”

The government didn’t wait for a pat on the back and it instead quickly contracted Tesla for another giant energy storage project;D

We reported this weekend that Tesla will be installing Powerwalls and solar power on 50,000 homes to create the biggest virtual power plant in the world.

The project would result in 250 MW and 650 MWh of capacity, which could also be used for similar services as Tesla’s giant Powerpack installation but distributed in residential communities.

Tesla’s Battery in Australia Is Surpassing Expectations

January 17, 2018

By Dylan McConnell


It’s just over one month since the Hornsdale Power Reserve was officially opened in South Australia at the Hornsdale wind farm. The excitement surrounding the project has generated acres of media interest, both locally and abroad.

The aspect that has generated the most interest is the battery’s rapid response time in smoothing out several major energy outages that have occurred since it was installed.

Following the early success of the South Australia model, Victoria has also secured an agreement to get its own Tesla battery built near the town of Stawell. Victoria’s government will be tracking the Hornsdale battery’s early performance with interest.

Generation and Consumption

Since there are losses associated with energy storage, it is a net consumer of energy. This is often described in terms of “round trip efficiency,” a measure of the energy out to the energy in. In this case, the round trip efficiency appears to be roughly 80 percent.

The figure below shows the input and output from the battery over the month. As can be seen, on several occasions the battery has generated as much as 100 MW of power, and consumed 70 MW of power. The regular operation of the battery moves between generating 30 MW and consuming 30 MW of power.

Over the full month of December, the Hornsdale power reserve generated 2.42 GWh of energy, and consumed 3.06 GWh.

As can be seen, the generation and consumption pattern is rather “noisy,” and doesn’t really appear to have a pattern at all. This is true even on a daily basis, as can be seen below. This is related to services provided by the battery.

Generation and consumption of the Hornsdale Power Reserve over the month of December 2018. Author provided [data from AEMO]


Frequency Control Ancillary Services

There are eight different Frequency Control Ancillary Services (FCAS) markets in the National Electricity Market (NEM). These can be put into two broad categories: contingency services and regulation services.

Contingency Services

Contingency services essentially stabilize the system when something unexpected occurs. These are called credible contingencies. The tripping (isolation from the grid) of large generator is one example.

When such unexpected events occur, supply and demand are no longer balanced, and the frequency of the power system moves away from the normal operating range. This happens on a very short timescale. The contingency services ensure that the system is brought back into balance and that the frequency is returned to normal within five minutes.

In the NEM there are three separate timescales over which these contingency services should be delivered: six seconds, 60 seconds, and five minutes. As the service may have to increase or decrease the frequency, there is thus a total of six contingency markets (three that raise frequency in the timescales above, and three that reduce it).

This is usually done by rapidly increasing or decreasing output from a generator (or battery in this case), or rapidly reducing or increasing load. This response is triggered at the power station by the change in frequency.

To do this, generators (or loads) have some of their capacity “enabled” in the FCAS market. This essentially means that a proportion of its capacity is set aside, and available to respond if the frequency changes. Providers get paid for the amount of megawatts they have enabled in the FCAS market.

This is one of the services that the Hornsdale Power Reserve has been providing. The figure below shows how the Hornsdale Power Reserve responded to one incident on power outage, when one of the units at Loy Yang A tripped on December 14, 2017.

Regulation Services

The regulation services are a bit different. Similar to the contingency services, they help maintain the frequency in the normal operating range. And like contingency, regulation may have to raise or lower the frequency, and as such there are two regulation markets.

However, unlike contingency services, which essentially wait for an unexpected change in frequency, the response is governed by a control signal, sent from the Australian Energy Market Operator (AEMO).

In essence, AEMO controls the throttle, monitors the system frequency, and sends a control signal out at a four-second interval. This control signal alters the output of the generator such that the supply and demand balanced is maintained.

This is one of the main services that the battery has been providing. As can be seen, the output of the battery closely follows the amount of capacity it has enabled in the regulation market.

More Batteries to Come   

Not to be outdone by its neighboring state, the Victorian government has also recently secured an agreement for its own Tesla battery. This agreement, in conjunction with a wind farm near the town of Stawell, should see a battery providing similar services in Victoria.

This battery may also provide additional benefits to the grid. The project is located in a part of the transmission network that AEMO has indicated may need augmentation in the future. This project might illustrate the benefits the batteries can provide in strengthening the transmission network.

It’s still early days for the Hornsdale Power Reserve, but it’s clear that it has been busy performing essential services and doing so at impressive speeds. Importantly, it has provided regular frequency control ancillary services — not simply shifting electricity around.

With the costs and need for frequency control service increasing in recent years, the boost to supply through the Hornsdale Power Reserve is good news for consumers, and a timely addition to Australia’s energy market.

Agelbert NOTE:For smoothing electrical energy demand and preventing appliance damaging frequency and voltage fluctuations, no fossil fuel or nuclear power generating plant can EVER match the lightning speed and reliability of a large battery system.

The only thing that comes close, but still takes seconds (causing brief frequency and voltage fluctuations that you don't notice but your electronics certainly do not like), instead of the lightning fast battery response of fractions of a second, is hydroelectric power because valves can quickly force torrents of water through pelton wheels powering electricity generators.

Battery systems are the Renewable Energy smoothing solution to the problem of intermittent solar, wind, tide, hydro, etc. because they provide an added guarantee of uninterrupted clean power that totally eliminates the need for alleged "baseload" coal or nuclear AND natural gas super expensive peaking power plants.

This has been known by the fossil fuelers for at least a half a century. That is why they continue to do everything they can to stop these systems from coming online. We need fossil fuel and nuclear dirty energy sources like  like a dog needs ticks.  >:(

If we survive the present Trumpism dystopic stupidity, I believe all the excess Renewable Energy harvested from facilities that are being built all over the world will eventually be stored, not just in battery systems and dams, but also in potential energy systems (massive cable suspended weights in subterranean structures up to a thousand feet long) that can kinetically power generators by gravity even faster than hydroelectric power.

Many people do not realize that, at present, a great deal of generated energy by fossil fuel and nuclear power is thrown away in what is called "shunting". As you read in the article above, a certain amount of power capacity HAS TO be kept off line so that when a demand spike shows up, the frequency and voltage do not get out of acceptable limits.

All this is because conventional polluting power sources like coal and nuclear are TOO SLOW in the ramp up and ramp down. 

Also, those peaking power plants that use natural gas are, though much quicker, still too slow to avoid the huge amounts of shunted energy thown away routinely.

Renewable Energy and battery systems have the potential to reduce shunting to a fraction of what it is today and eventually eliminate this wasteful process altogether. Fossil Fuelers and Nuke Pukes don't like to talk about shunting because, aside from the polluting piggery , Shunting is their horrendously wasteful Achilles Heel.

In the future, I envision large battery systems as mainly a smoothing technology used to coordinate all the Renewable Energy coming in and storing it when there is an excess, while providing millisecond smooth frequency and voltage instant power until the hydroelectric and/or gravity systems come online a second or three later.  The present six seconds, 60 seconds, and five minutes time scales will be relegated to the cave man days of fossil fuel and nuclear polluting energy sources.  ;D

There is no place for slow starting dirty energy generation in this truly practical and sustainable picture involving supplying clean, non-polluting power to human civilization.

The Fossil Fuelers DID THE Clean Energy  Inventions suppressing, Climate Trashing, human health depleting CRIME,   but since they have ALWAYS BEEN liars and conscience free crooks, they are trying to AVOID   DOING THE TIME or     PAYING THE FINE!     Don't let them get away with it! Pass it on!

Agelbert NOTE: The significant thing about this EV service is that they use a new type of battery technology (solid electrolyte) that is, for all practical purposes, impervious to fire from overheating or violent penetration during a crash. Learn more about this exciting new Lithium Metal Polymer (LMP®) battery technology  below.


blueSG network of 1,000 shared electric Bluecar vehicles in Singapore


THE SERVICE

Launched in the year of 2017, BlueSG offers a new smart and affordable mobility option to all Singaporeans, complementing public transport.

BlueSG members will have access to a network of 1,000 shared electric Bluecar vehicles, 24/7, at self-service stations located in public housing, city center and commercial estates around Singapore. The service is point to point, which means there’s no need to return the car to your starting point, nor to bear the cost of maintenance or insurance of a own vehicle.
The BlueSG service will be available to anyone over 21 years of age with a valid driver’s license.

BlueSG is a subsidiary of the Bolloré Group which has launched the world’s largest and most successful car sharing, Autolib’ in Paris. . BlueSG will become the world’s second largest EV car sharing service.
 

THE PROJECT


A Request for Information (RFI) was issued in 2014 by the Land Transport Authority of Singapore (LTA) and Economic Development Board (EDB) and received proposals from 13 major consortia. Bolloré Group was selected for the quality of its proposal which complemented the public transport network, its strong track record – 6 years of successful implementation in Paris, and its commitment to Singapore.

On June 30, 2016, Singapore and the Bolloré Group signed the agreement that demonstrated the Group’s commitment to fully support Singapore’s public transport policy, through the creation of alternative and environmentally-friendly transportation solutions to the traditional car.

In December 2017, BlueSG car sharing service will officially be launched with an estimate of 30 stations and 80 Bluecars.

Under the agreement, the car-sharing programme will eventually include 500 stations equipped with 2,000 charging points. Of these, 20 per cent (or 400 charging points) will be for public use. The first fleet of Bluecars is also currently being commissioned in Singapore and will be part of the 1,000 strong EV fleet in the future.



THE BLUESG TECHNOLOGY


BlueSG is offering a one-way and all-electric car sharing service thanks to its Bluecar vehicle equipped with Lithium Metal Polymer (LMP®) batteries from Blue Solutions, a Bolloré subsidiary as BlueSG.

LMP® technology is the culmination of an ambitious research and development program started more than twenty years ago. Made of thin films of material produced using extrusion techniques perfected by the Bolloré Group, LMP® batteries offer high energy density while ensuring safety of use. They provide unrivaled autonomy and excellent performance in all weather conditions. They are dry batteries (meaning “entirely solid”), which gives them numerous advantages, particularly in terms of safety. Solid electrolytes effectively reduce local pollution risks in the event of an accident or damage to the integrity of the battery pack. The LMP® batteries contain no solvents, no rare earth metals, and no cobalt.

These batteries can fulfill the needs of many different markets and meet the two primary challenges of the energy transition: developing clean transportation and smart energy management. Blue Solutions holds the intellectual property rights allowing it to manufacture and market batteries based on LMP® technology.
 

OUR AMBITIONS IN SINGAPORE

Thanks to the LMP® technology, the Bolloré Group decided to develop mobility (car sharing and electric vehicles) and stationary applications to address the environmental concerns. The Group ambition is to go further in the development of electro mobile solutions in particular thanks to its subsidiary that opened its new office in Singapore in September 2017.

Indeed, in addition to the fleet of 100% electric cars and charging points, the Bolloré Group is also establishing a new R&D center for Asia in Singapore, and an innovation center for partners to develop, test, and implement technological innovations in the mobility, data analysis and batteries.

Finally, the Bolloré Group also aims to deploy in the city-state and in Asia other modes of public transport, such as the Bluebus and the Bluetram equipped with supercapacitors. All of these would help create over 250 jobs in the country.

Vanadium Flow Batteries for Cost-Effective Energy Storage: An Interview with Angelo D’Anzi, CTO of StorEn Technologies

November 21st, 2017 by Sponsored Content

SNIPPET:

How can you achieve such a low cost per kWh? ???

StorEn TechnologyCost is crucial for the adoption of energy storage. Our work is about bringing evolution to the technology with the objectives to improve performance as a way to drive down costs. We developed a disruptive battery technology based on both chemical and engineering solutions, leading to a 50% cost reduction. We are targeting a price of $400/kWh with a 25 year duration with no decay.  :o 


The great breakthrough is our innovative high-power electrodes made with nanomaterials and a proprietary functionalization process. With this innovation we have doubled power density over traditional batteries, while running at low pressure.

The ability to run at low pressure means that less of the battery’s own energy is required to run the pumps, hence round-trip efficiency is increased. Additionally, duration of the battery is also increased. To support the electrochemical activity, we couple our Hi-Power Nano-Structured Carbon Electrode to our MULTIGRID™ multipoint flow distribution to deliver an increase in power in excess of 50%.

We also wanted to make a battery that was virtually maintenance-free, like a car battery, for trouble-free operations and reduced Total Costs of Ownership. We developed two proprietary systems, RESAFE™ and EQUILEVELS™. These two systems support a battery that is virtually maintenance-free by eliminating service activities.

Our battery can be monitored remotely with our built-in BMS (Battery Management System). Therefore we implement a shift from scheduled on-site inspections to a maintenance-on-demand model. For example, if one of our batteries was installed in a remote telecommunications tower for power back-up, remote monitoring can reduce or eliminate the need for periodic on-site visits, which can translate in significant cost savings.

Scientists add asphalt to lithium batterius that charge up to 20 times faster  :o  ;D

LAST UPDATED ON OCTOBER 3RD, 2017 AT 7:41 PM BY TIBI PUIU

SNIPPET:

Just a touch of asphalt is enough for high-capacity lithium metal batteries to charge 10 to 20 times faster than the commercially available lithium-ion variety. Additionally, the novel batteries last longer and are safer than current alternatives.

Agelbert NOTE:
Off the shelf Lithium ion batteries now use carbon anodes, so this modification is not that big or expensive of a change. That said, I am a bit skeptical because faster charging does not give any guarantee of avoiding dendrite formation that degrades the batteries. The scientists claim the asphalt doping prevents dendrite formation. Maybe during the charge itself, but what about while it is sitting? I am not convinced by their assurances. Repeated faster charging might even cause the dendrites to grow faster, so I will adopt a wait and see attitude in regard to this innovation.

Tesla Sends Hundreds of Batteries to Puerto Rico   

Tesla is sending its Powerwall system to Puerto Rico as the island deals with widespread power loss in the wake of Hurricane Maria.

According to Electrek, the company has been quietly shipping hundreds of battery packs to be paired with solar panels to Puerto Rico ever since the storm cleared.

Fortune reported that Tesla employees are currently on the U.S. territory installing the batteries and repairing solar systems, as well as coordinating efforts with local organizations.

Much of the island's 3.4 million American citizens are currently without power and disconnected from modes of communication. Officials estimate that some areas will not see their power restored for months. As Climate Nexus pointed out, "the future of the island's bankrupt and corrupt utility and its fossil-fuel-heavy colonial legacy are now top of mind as experts and officials begin to tackle the best way to restore power and rebuild the island's power grid."

While there is still a long way to go rebuild, Tesla's batteries will help enable the island's generation of clean and renewable solar energy in the interim and in the future.   


The company previously made headlines for helping Model S and Model X owners in Florida escape Hurricane Irma by extending the battery range of its cars.

Tesla CEO Elon Musk has also personally donated $250,000 to the relief effort, Electrek noted.  

A number of companies and business leaders have contributed to hurricane relief efforts. Fellow billionaire mogul Richard Branson, who faced two damaging hurricanes in a row from his home in the British Virgin Islands, has met with government representatives from Britain and the U.S. to set up a green fund to rebuild the hurricane-wrecked Caribbean.

"As part of that fund we want to make sure that the Caribbean moves from dirty energy to clean energy," Branson also told Thomson Reuters Foundation.

"If all that money could be invested in clean energy, in powering the world by the sun and by the wind, where we won't have to suffer these awful events in the future, how much better than having to patch up people's houses after they've been destroyed?" the Virgin Group founder said.

Diamonds Are A Battery’s Best Friend — Potential Lithium-Ion Battery Breakthrough

August 28th, 2017 by Steve Hanley

SNIPPET:

Dendrites are the enemy of lithium-ion batteries. As ions transfer back and forth between the anode and the cathode in those batteries, they can leave behind tendril-like buildups called dendrites. Similar to stalactites that form inside a cave, these battery buildups (dendrites) are one of the main causes of lithium battery malfunction.

Lithium is the ideal material for cathodes in terms of energy storage potential, but pure lithium cathodes suffer from significant dendrite formations. To solve that issue, battery makers have started blending the lithium with graphene. The resulting compound inhibits the formation of dendrites but also significantly reduces the energy storage capacity of the cathode. A pure lithium cathode is capable of storing 10 times as much electrical energy as a cathode made of lithium and graphene.

Researchers at Drexel University, working closely with colleagues at Tsinghua University in Beijing and Hauzhong University of Science and Technology in Wuhan, China, may have found a way to inhibit the formation of dendrites and allow cathodes to be made with a higher percentage of lithium. Their discovery involves adding nanosized diamonds to the electrolyte inside the battery.

On August 25, Professor Yury Gogotsi and his research team from the Department of Materials Science and Engineering at Drexel published their research in the journal Nature Communications. Entitled “Nanodiamonds Suppress Growth of Lithium Dendrites,” it describes how diamond particles 10,000 times smaller than the diameter of a human hair curtail the electrochemical deposits that form dendrites.

One μm equals one millionth of a metre (or one thousandth of a millimetre, 0.001 mm, or about 0.000039 inch). The width of a single human hair ranges from approximately 10 to 200 μm.

ICE made with excess Renewable Energy (or during off peak hours) is an excellent "energy battery" to provide cooling during hot temperatures.   


“Ice Battery” Technology Set To Cool Australian Homes & Cut Peak Power Demand

August 21st, 2017 by Guest Contributor

Originally published on RenewEconomy.

By Sophie Vorrath

SNIPPET:

US-made thermal “ice battery” energy storage technology that could dramatically change the way people cool their homes in summer – potentially cutting household peak power consumption by up to 95% – is poised to take on the Australian market, through a distribution deal with local solar hot water company Apricus.


California-based Ice Energy inked an agreement, in June, making the Melbourne-based Apricus the exclusive distributor of all its thermal energy storage products in Australia, covering all market segments, including utilities, commercial and industrial, and residential.

The company is best-known for its commercial and industrial Ice Bear technology, which works alongside air conditioning units by freezing water at off-peak periods, or when excess solar or wind power is available, and using the “ice battery” to provide power-free cooling during on-peak periods.

It's a great idea. Storage is still our Achilles heel for renewables.  Off grid especially.  The arrays are getting bigger and bigger with no way of using mid summer peak production.  The industry is also playing with electric hot water for summer use.  Gas in winter.  They are are all batteries really.
Cheers,  David B

ICE made with excess Renewable Energy (or during off peak hours) is an excellent "energy battery" to provide cooling during hot temperatures.   


“Ice Battery” Technology Set To Cool Australian Homes & Cut Peak Power Demand

August 21st, 2017 by Guest Contributor

Originally published on RenewEconomy.

By Sophie Vorrath

SNIPPET:

US-made thermal “ice battery” energy storage technology that could dramatically change the way people cool their homes in summer – potentially cutting household peak power consumption by up to 95% – is poised to take on the Australian market, through a distribution deal with local solar hot water company Apricus.


California-based Ice Energy inked an agreement, in June, making the Melbourne-based Apricus the exclusive distributor of all its thermal energy storage products in Australia, covering all market segments, including utilities, commercial and industrial, and residential.

The company is best-known for its commercial and industrial Ice Bear technology, which works alongside air conditioning units by freezing water at off-peak periods, or when excess solar or wind power is available, and using the “ice battery” to provide power-free cooling during on-peak periods.

Agelbert NOTE: Israel has finally demonstrated a tremendous capacity for the obvious.  ;) ;D  I mean, DUH, it's hotter than a pistol over there with SUN, SUN and MORE SUN baking the stuffing out of the plant life, the animals, the bugs and the people for at least the last 2,000 YEARS and more. Pumped storage is the ultimate low maintenace cost, base load level, INSTANT on demand, Renewable Energy Storage medium. And putting a water surface where there is a lot of desert increases the relative humidity in the surrounding area, thereby aiding in plant life proliferation and desert greening. Yeah, I know, who coulda knowd? 

It has never ceased to amaze me how so many gooberments all over the world can "justify" taxing we-the-people to build pipelines hundreds of miles long to move hydrocarbon CRAP from here to there, over ALL KINDS of terrain, but somehow never seem to be been able to DO THAT with ocean OR fresh water UPHILL (except for the extremely short pipes right next to dams that have some minuscule pumped storage equipment).  The fossil fuel industry will indignantly claim they pay to build the pipelines, not the gooberment. That is a very clever LIE. In 1987 our fossil fuel gooberment gave the lie to that half truth, but most people, OF COURSE, are not aware of that, thanks to all that "SILENCE" from the mainstream media.

Better late than never, I suppose.

Agelbert NOTE: The payback on this new super-capacitor is about nine years. Some will claim that is too much. Those who do are ignorant fools who do not GET the fact that COST of using fossil fuels is the Sixth Mass Extinction. You CANNOT EVER GET ANY "PAY BACK" FROM fossil fuel and nuclear POLLUTING ENERGY SOURCES!

It is amazing how STUPID people can be when they irrationally cling to the unsustainable fossil fuel powered status quo. The product below is NOT "pie in the energy sky". They are manufacturing it NOW. It WORKS in tiny devices and in scale all the way to an electric bus and even utility level storage solutions.

Consequently, this super-cap will be fought TOOTH AND NAIL by the fossil fuelers because it DESTROYS all their Renewable Energy electric powered device hand wringing about "slow charging times". Yes, you will probably need to "fill your tank" with charge more often than filling your gasoline tank. But this small inconvenience is justified considering you DO NOT EVER POLLUTE and can recharge in 30 SECONDS. IOW, you can stop for a cup of coffee or a bathroom break and keep going as FAR AS YOU WANT TO GO.

NO MORE "range anxiety" on EVs means the DEATH of hydrocarbon fueled polluting engines for transportation. GOOD!

This super-cap technology IS NOT "ten years away", as some IDIOT(s) may try to claim here. But, it may be delayed by fossil fuel loving CROOKS AND LIARS that corrupt and pollute the US Government and our country. So, Europe and China will probably be using this technology for EVs much sooner than the backward banana republic called the USA.

The super capacitors have real potential. It will be interesting to watch them roll out and see where they go.  The arrays on off grid systems are getting larger all the time faster then the battery banks   the super caps might be a good bridge between the fast changing solar availability and the batteries slow take up of charge.
Interesting times.


True. Notice what KiloWatt Labs CEO Omer Ghani said in the video after explaining, step by step, that they had ALREADY overcome the super-cap rapid discharge problems along with obtaining lithium ion batttery energy density compatibility without the high lithium ion price:
Quote
"We have to get people to believe us."  :o

Omer Ghani has the product, has the evidence that the product works and is cheaper than lithium ion battery technology at the same or greater energy density, YET, they have trouble getting people to believe them! THAT is prima facie evidence of how incredibly brain washed our society has become (at the level of ENGINEERS!), to the point where they take as "thermodynamics gospel" the biosphere math challenged ERoEI double talk (happy talk for fosssil fuels and "it's just too costly" for clean energy sources), published for the last half century BY THE FOSSIL FUEL INDUSTRY (Yep, THEY put those numbers, including thermodynamics and fluid mechanics assumptions, in the engineering textbooks! Amory Lovins of the Rocky Mountain Institute has proven by experimentation that a lot of those numbers are WRONG!), as the "standard" for credibility and doability. 

No wonder it is so hard to get out of the death grip of the fossil fuel industry destructive influence on our biosphere and democracy. The idiots smokin' the fossil fuel baloney accuse everybody advocating new inventions that enhance clean energy use of "pipe dreams" or "smokin' somethin'". Ridicule is the FIRST tool used to to try to defend the unsustainable status quo. The ERoEI polluting energy sources happy talk comes next. The fossil Fuel Industry century of propaganda BULLSHIT has worked. Let us hope more people wake up to the stupidity of believing absolutely anything coming from the polluters. We are all dead if we do not destroy the fossil fuel industry VERY, VERY soon.

In the year of 1936 during the middle of summer, an ancient tomb was discovered during construction of a new railway line near Bagdad city in Iraq. The relics found in that tomb were about 2000 years old. Among these relics, there were some clay jars or vessels which were sealed at the top with pitch. An iron rod, surrounded by a cylindrical tube made of wrapped copper sheet was projected out from this sealed top.

When these pots were filled with an acidic liquid, they produced a potential difference of around 2 volts between the iron and copper. These clay jars are suspected to be 2000 year old battery cells.

This area of investigation has always fascinated me. We are ever-so-smug in our presentism, that the ancients were a bunch of ignorant rubes, but there are enough discoveries found in the wrong place to indicate that we are wrong.

And then of course is the question of where the knowledge came from
.

 

Yep. Your observation has some very important nuggets of wisdom that most people do not even begin to undertand, never mind taking to heart in order to realize how delibertely dumbed down our society is.

The most important part of your obervation is the fact that people are indoctrinated to BE smug about our incredibly, STUPID, suicidally destructive society.

Smugness breeds the overcondence that always precedes dumb, and sometines trajic, errors in judgement.

We don't need to go back to ancient times to see that at work now. Tesla made it quite clear in the early 20th century that we DID NOT NEED to use fossil fuels for ANYTHING because energy was plentiful. But ignorant, brain washed people claim cheap, clean energy, especially those who have eaten the happy talk for the fossil fuel liars and crooks, as advocated by Nikola Tesla (and Thomas Edison too, by the way) is a "pipe dream".  ::)

Smug, brain washed people that actually believe the BALONEY that we "owe" our standard of living to our "loyal servants, the fossil fuel industry", when there is NO QUESTION that the microscope (and the discovery of germs that cause disease) is the REAL REASON for the human population explosion, will continue to wallow in their stupidity until it is too late. Personal hygiene is the CAUSE of the human population explosion, not the fossil fuel based "economy".

The ancients certainly were not ignorant rubes. Nikola Tesla and Thomas Edison weren't rubes either.




Before Edison said the following, he had gone on record over a decade earlier clearly stating that hydrocarbon fuels for internal combustion engines were INFERIOR to ethanol BECAUSE of all the waste heat and resultant added engine wear. Ethanol only engines would be TWO THIRDS lighter than hydrocarbon powered engines because ethanol runs cool (because it carries it's own oxygen with it causing TOTALLY EVEN BURNING), as well as being renewable and polluting less. And it is also propaganda mendacity out there that claims we would "cut into world food supply by growing ethanol crops".   

But telling bold face crocodile tear laden lies has never stopped the brain washers that so many here smugly worship.

Tesla Wins Contract for South Australia Energy Storage Project 

July 7, 2017

By Perry Williams, Bloomberg

SNIPPET:

Elon Musk’s Tesla Inc. has won a tender to supply what the billionaire says is the world’s largest lithium-ion battery to back up the state of South Australia’s blackout-plagued power grid, making good on a promise first made over Twitter four months ago to help solve the state’s energy woes.

Tesla will provide 100 MW of storage by Dec. 1, pairing it with a wind farm at Hornsdale north of Adelaide operated by France’s Neoen, according to a statement on Friday from South Australian Premier Jay Weatherill. The system, which will have capacity of 129 MWh, will provide enough power for more than 30,000 homes, Tesla said in a separate statement.

We’re talking about something that’s three times as powerful as the next biggest battery installation in the world,” Musk told reporters in Adelaide.

Musk had previously promised to build the system and get it working within 100 days of a contract being signed or Tesla would provide it free, a vow he backed up on Friday.

Quote

“We actually insisted when doing the contract that we be held to the 100 days or it’s free,” Musk said. “That’s what we said publicly, that’s what we’re going to do.”

Big batteries can store power when the sun doesn't shine

Lloyd Alter (@lloydalter) Energy / Renewable Energy June 5, 2017

© Andrew Roberts/ New York Times

SNIPPET:

What is the difference between a battery and a power source? It is sometimes hard to distinguish. If you build a dam and capture the energy of falling water, it is considered power generation from a power source, namely gravity. But if you pump water up a hill and store it behind a dam until you need it, that's acting as a battery; it is not making energy, it is just storing it. It is a really important distinction; it is one of the reasons we are not fans of hydrogen, considering it more a battery than a fuel.

Diane Cardwell of The New York Times writes about The Biggest, Strangest "Batteries" and explains how really, anything that can store energy and release it later is a battery.

Listen Up: What Home Owners Need To Know About Battery Storage Systems 
 

May 22, 2017

Since the sun does not shine at night we need a way to store daytime-generated solar energy. Net metering is an elegant and 100% efficient way to shift excess solar power, but that system will not work at high solar penetration levels. Never mind the fact that utilities are loath to allow their customers to generate electricity for less than it costs them to deliver this power.

As a result, battery storage is on the minds of almost all new solar customers. Storage technology, incentives, favorable electric rates and control software are all evolving rapidly. There are currently about a dozen companies with battery storage systems designed for use with rooftop solar. Like peanut butter and chocolate, many solar companies are starting to offer battery storage systems along with their solar systems.

My advice is to proceed with caution. Even though off-grid battery storage systems have been available for years, we are at the very early stages of grid-tied solar combined with battery storage. From a hardware standpoint, battery storage costs are plummeting, and new inverters/charge controllers are being developed. Perhaps more importantly, software that will efficiently interact with solar, batteries, the grid and your home energy consumption still has limited functionality. For more about the practicalities of home battery storage, Listen Up to this week’s Energy Show on Renewable Energy World.

About the Energy Show


As energy costs consume more and more of our hard-earned dollars, we as consumers really start to pay attention. But we don't have to resign ourselves to $5/gallon gas prices, $200/month electric bills and $500 heating bills. There are literally hundreds of products, tricks and techniques that we can use to dramatically reduce these costs — very affordably.

The Energy Show on Renewable Energy World is a weekly 20-minute podcast that provides tips and advice to reduce your home and business energy consumption. Every week we'll cover topics that will help cut your energy bill, explain new products and technologies in plain English, and cut through the hype so that you can make smart and cost-effective energy choices.

About Your Host

Barry Cinnamon is a long-time advocate of renewable energy and is a widely recognized solar power expert. In 2001 he founded Akeena Solar — which grew to become the largest national residential solar installer by the middle of the last decade with over 10,000 rooftop customers coast to coast. He partnered with Westinghouse to create Westinghouse Solar in 2010, and sold the company in 2012.

His pioneering work on reducing costs of rooftop solar power systems include Andalay, the first solar panel with integrated racking, grounding and wiring; the first UL listed AC solar panel; and the first fully “plug and play” AC solar panel. His current efforts are focused on reducing the soft costs for solar power systems, which cause system prices in the U.S. to be double those of Germany.

Although Barry may be known for his outspoken work in the solar industry, he has hands-on experience with a wide range of energy saving technologies.  He's been doing residential energy audits since the punch card days, developed one of the first ground-source heat pumps in the early ‘80s, and always abides by the Laws of Thermodynamics.  ;D

Vehicle-To-Grid Discharge, Even At Constant Power, Is Detrimental To EV Battery Performance, Study Finds  :(

May 16th, 2017 by James Ayre

SNIPPET:

There have long been critics of the idea of widespread use of electric vehicle (EV) vehicle-to-grid (V2G) technologies for a variety of reasons, but largely in relation to the potential damage done to EV batteries, and thus reduced battery lifespan.

New research from the Hawaii Natural Energy Institute at the University of Hawaii at Manoa seems to clearly support this assertion — the extra cycling that accompanies use of an EV battery for grid balancing, even when at constant power, reduces EV battery cell performance significantly.

To be more specific, the use of an EV with V2G tech could reduce the working lifespan of an EV battery pack to under 5 years time, according to the new work.  :(  :P

The researchers note, though, that simply delaying the charging of EVs as a means of balancing the grid would have only a “negligible” effect on EV batteries, and could thus represent a better option. However, this could prove to not be the case in environments warmer than “room temperature.”

V2G Battery Degradation


https://cleantechnica.com/2017/05/16/vehicle-grid-discharge-even-constant-power-detrimental-ev-battery-performance-study-finds/

Agelbert COMMENT: Well, provided this is true, EV car manufacturers should use common sense and join with electric Utilities to offer EV car buyers a 10 year guarantee, WITHOUT ANY ADDED CHARGES, for replacing the used battery pack with a new one. I make the caveat about "no added charges" because the fun and games on the average lead acid battery "guarantee" is, and always was, a rip off.

Avoiding peaking costs is well worth the 10 year battery pack guarantee. In fact, if we had a sane government, they would REMOVE all the fossil fuel "subsidies" and, instead provide EV battery pack 10 year guarantee subsidies as a matter of National Security grid stability.

But common sense and logic in regard to renewable energy is rather difficult for the United Petro-States of America.



Fossil fueler shows up with the old "not ready for prime time" baloney disguised as prudent advice:
wattleberry 

A useful warning to users of today's batteries but of limited relevance to their successors which, if anything, will be encouraged by the disclosure of another flaw awaiting correction in a key component of a product which is still at a very early stage of evolution.

agelbert > wattleberry  

Like what, the tendrils that grow and short them? We know about that. The battery development is quite mature, thank you very much. It's the fossil fuel polluting machine called an internal combustion engine that never got past the profit over people and planet stage. Gas stations will soon go the way of the dodo bird too.

The only issue with batteries of any significance that needs improvement is rapid replacement technology. We NOW have access to electricity in FAR more places than we have access to gasoline. All we need is a small "spare" battery pack that can take us home or too a quick pack replacement location nearby if our main battery pack fails.


eveee 

 
This discussion needs more clarity. People are defining whats better in odd ways. How do we define it? By how much the EV owner saves in retail electricity costs vs how much the value of the car is reduced by battery degeneration?

I tend to feel V2G doesn't make sense, because a car is not just a battery. However, when the battery is used more, the value of the car reduces.

If you want V2G, get a PowerWall instead. Then you are only reducing the value of the PowerWall, not the car.

A PowerWall is 6500. A Model S is > 65000. 10x.

Now on the other hand, we are only looking at one storage scenario, load shifting.

Already, California is starting a demand response program that pays users not to use electricity during peaks and allow the utility to dial back demand when it needs to.

That is an area for an EV owner to benefit by allowing charging to be controlled or timed to miss expensive peak demand times. That makes total sense.

California: 'We Are Just Getting Started'   

   

May 11, 2017

By Jason Deign      energy storage

If you thought California’s lead as an energy storage market might fade in the face of upstarts such as Australia or Germany, then think again. Recent moves might see new gigawatts of capacity being installed across the state by 2020.

 The most significant development was the recent reopening of California’s Self-Generation Incentive Program (SGIP) with more than US$448m in funding dedicated to energy storage.

The cash, 79 percent of an almost $567m funding package available through 2019, is expected to create a surge in behind-the-meter energy storage deployments across the state.

Most of the storage budget is aimed at what the California Public Utilities Commission (CPUC) calls ‘large-scale storage,’ or systems of more than 10 kW. But 13 percent, or just over $57m, will be for residential installations.

“The incentive level for energy storage systems larger than 10 kW that do not take the investment tax credit (ITC) and all residential systems 10 kW and smaller will be set at 50 cents/watt-hour,” says the CPUC on its website.

Projects That Are Larger than 10 kW

“Projects that are larger than 10 kW and take the ITC will have a lower initial incentive rate of 36 cents/watt-hour.
 
“We expect that demand will exceed the amount of funding for incentives at that level very quickly, and we therefore expect incentive levels to decrease by 10 cents/watt-hour shortly after SGIP reopens.”

The new SGIP will act in addition to a provision for behind-the-meter storage that already exists within the Assembly Bill 2514 (AB 2514) mandate that has powered deployments in California so far.

The AB 2514 provision is for 200 MW of capacity, to be procured by 2020 and installed by 2024.

But the SGIP, which had its budget doubled under legislation agreed last year, “is going to blow it out of the water,” said Janice Lin, founder and executive director of the California Energy Storage Alliance (CESA).

Instrumental In Getting the SGIP to Focus on Storage

CESA was instrumental in getting the CPUC to focus the SGIP on storage, she told Energy Storage Report. Originally the program had been solely dedicated to demand response, she said.

Behind-the-meter deployments are also being boosted in California by AB 2868. This last year directed the CPUC to get the state’s three largest electrical utilities to “accelerate widespread deployment of distributed energy storage.”

In practice this will add up to 500 MW more of capacity to the system, up to 25 percent of which could be behind the meter. “We’re waiting for those utility applications,” Lin said.

On top of that, AB 2514, which is a biennial procurement program, is set to continue and is expected to mandate further utility deployments in future. But it doesn’t stop there.

This legislative session has seen no fewer than three bills emerge in the last fortnight that could each add significant further energy storage capacity to the California electricity system.

Procuring 120 MW of Energy Storage Capacity

One is a Senate Bill, SB 801, which requires the Los Angeles Department of Water and Power and Southern California Edison to procure 100 MW and 20 MW, respectively, of energy storage capacity.

The procurement has been put forward on an emergency basis to reduce the impact of the Aliso Canyon natural gas storage failure.

Finally, two other bills, SB 338 and AB 1405, aim to address California’s clean peak energy problem, commonly known as the duck curve. “The neck of the duck is the most challenging portion of our net load,” explained Lin.

And it’s getting worse. This month the California Independent System Operator (CAISO) “is expected to release a new animal,” she said. “What I’ve heard from CAISO is the ramp of the new duck is shocking. The neck is huge.”

CAISO now sees storage as a key tool for dealing with challenges such as the duck curve and Aliso Canyon, she said.

If Clean Peak Energy Bills Are Implemented

If the clean peak energy bills are implemented it is unclear how much extra energy storage capacity they might add since other measures, such as demand response, might form part of any eventual package.

However, CESA roughly calculates that it could amount to “hundreds of megawatts of storage,” said Lin. “The fundamental underlying trends are very solid for storage.

“Storage is a very helpful enabler to more and more clean energy in our mix,” she said. “There is a lot going on in California right now. While California has been trailblazing, in some ways we are just getting started.”

New Virginia Law Expands Solar Energy Development Authority to Include Energy Storage
   
May 9, 2017

By Renewable Energy World Editors     solar
 
Virginia Gov. Terry McAuliffe yesterday signed a bill authorizing the expansion of the state’s Solar Energy Development Authority to include energy storage.

The legislation is part of a series of bills signed by McAuliffe that promote wind, solar and energy storage technologies.

SB 1258, introduced by Sen. Adam Ebbin, expands the purpose of the new Solar Energy and Battery Storage Development Authority to include positioning the state as a leader in research, development, commercialization, manufacturing, and deployment of energy storage technology.

The powers of the authority are expanded to include

•Promoting collaborative efforts among Virginia's public and private institutions of higher education in research, development, and commercialization efforts related to energy storage,

•Monitoring relevant developments nationally and globally,

•Identifying and working with the state’s industries and nonprofit partners.

In addition, the measure expands the size of the authority 11 to 15 members.

“Today, I am honored to sign these bills into law, furthering the great work we’re doing to support and promote the clean energy sector across the Commonwealth,” McAuliffe said at the bill signing ceremony, according to the governor’s office. “It is clear that Virginia is moving in the right direction, especially with the recent announcement of record growth in our solar industry, but there is still work to do.  Together, with our partners in the General Assembly and the private sector, I will continue to implement policies that bolster the entire clean energy industry in the Commonwealth.”
 
The governor’s office said that other bills pertaining to renewables that were signed by McAuliffe yesterday include:

•SB 1393, which creates a path for the development of community solar programs in the service territories of Appalachian Power Company (ApCo), Dominion, and the Electric Cooperatives.  Each utility will develop its own territory-specific program that allows citizens and businesses the ability to “subscribe” to receive electricity generated by a small centrally-located solar generation system.

•SB 1394 and HB 2303, which are identical bills, create a Small Agricultural Generators Program — a new framework for the generation of renewable energy at agricultural facilities and how that energy can be sold to utilities.

•SB 1395 increases the allowable maximum size of renewable projects to be eligible to be permitted through the state’s Permit by Rule (PBR) process from 100 MW to 125 MW.  These projects are exempt from environmental review and permitting by the State Corporation Commission. SB 1395 also exempts projects that are being built for use by a single customer of a utility from having to apply for and receive a Certificate of Public Convenience and Necessity from the SCC.

US Energy Storage Caucus Launched to Educate Congress
   

May 9, 2017  By Renewable Energy World Editors        energy storage
 
U.S. Reps. Chris Collins (R-N.Y.) :o  ;D and Mark Takano (D-Calif.) yesterday launched the Advanced Energy Storage Caucus in Congress to educate Members of Congress regarding the benefits of storage to the U.S. electric system and investigate ways to accelerate job growth and investment in U.S. advanced energy storage industries.

The Energy Storage Association (ESA) said that Collins and Takano were joined for the launch by executives from leading utilities, developers, and manufacturers of storage technologies, including AES Energy Storage, S&C Electric, Stem Inc., and National Grid.

In addition, the caucus will periodically brief members of Congress on how energy storage is reshaping the way electricity is generated, distributed, and consumed, and how policy can remove impediments to greater use of battery storage.

"We need bipartisan solutions to help address our aging energy infrastructure," Collins said in a statement. “Energy storage technology will grow our economy and make sure American businesses can compete around the globe.”

Safety grid for power

Power grid operator Tennet and household power storage provider Sonnen plan to use a network of small-scale batteries to help reduce costs caused by grid bottlenecks between Germany’s windy North and the power-hungry South, reports Michael Bauchmüller in Süddeutsche Zeitung. “We want to integrate renewable power in the best possible way,” Tennet board chair Urban Keussen told the newspaper.

“We can manage that not only with copper, but also with intelligence.”
Sonnen managing director Philipp Schröder said that in a first stage, 6,000 batteries would be used to optimise the power grid. Households making their batteries available for the project, which will use blockchain encryption technology, will receive free power, according to the article. Keussen told newspaper Die Welt the use of blockchain was “the first step into a new energy world.”

Power grid revolution

The use of batteries to level out intermittent solar and wind generation in the Tennet and Sonnen project shows that “the Energiewende is making progress,” writes Andreas Mihm in Frankfurter Allgemeine Zeitung. “New offshore wind parks have been approved recently without a cent of eco power support, and now there is evidence for a revolution in the German power grid. For the first time, a grid operator will get access to thousands of small decentralised power storages all over Germany.

Transmission highway SuedLink enters next stage

The preparation procedure for building Germany’s high-voltage transmission highway SuedLink has entered a crucial stage, news agency dpa reports in an article carried by Welt Online. Following submission of the sectoral planning application for SuedLink’s last segment in the southern federal state of Baden-Württemberg, German federal grid agency BNetzA can now start the formal approval procedure for the 800-kilometre-long power line meant to transfer electricity from Germany’s windy north to industrial centres in the south, the article says.
 
In a separate article on Welt Online, dpa reports that about 3,000 people forming a human chain in the central German state of Thuringia protested against SuedLink’s construction. The transmission highway made the federal state the “pack animal” of German energy policy, protesters lamented according to the article.

Those bubbles on the seaweed fronds are oxygen produced by these amazing plants.

.. seaweed and other algae takes up 90 percent of all plant life on Earth 

Seaweed Could Revolutionize How We Power Our Devices
 

The answer to powering our devices might have been hiding in our sushi all along  ;D. An international team of researchers has used seaweed to create a material that can enhance the performance of superconductors, lithium-ion batteries and fuel cells.

--------------------------------------------------------------------------------

The team, from the U.S., the UK, China and Belgium, came up with the idea to mimic Murray's Law, which is a natural process within the structure of a plant's pores that pumps water or air throughout the plant to provide it energy. With Murray's law, the larger the pore, the less energy expended because the pressure is reduced, but it takes different variations in size to create a balancing act across the body of the plant and maximize energy potential. In seaweed's case, the plant has the perfect pore variation for regulating energy in real world applications.

"The introduction of the concept of Murray's Law to industrial processes could revolutionize the design of reactors with highly enhanced efficiency, minimum energy, time and raw material consumption for a sustainable future," said Bao-Lian Su, professor at the University of Cambridge and co-author of the research.

The scientists made the "Murray material" by embedding an extract of the seaweed into multiple layers of nano-fibers of zinc oxide, which created a hierarchy in the size of the pores. They believe the material can be used on rechargeable batteries, high performance gas sensing technology or even to decompose inorganic material in the oceans.

Seaweed is a fast growing algae that grows in abundance in coastal areas. It is estimated that seaweed and other algae takes up 90 percent of all plant life on Earth, making it a very sustainable plant for energy purposes. The team believes they could safely utilize 20,000 tons of the seaweed extract per year.

The Murray material could improve capacity by 25 times compared to the current graphite-based technology being used in lithium-ion batteries. The pores in the material also allow for a smoother charge/discharge process, improving stability and extending the life of batteries or fuel cells.

"Large scale manufacturability of this porous material is possible," said co-author Tawfique Hasan, also at Cambridge. "Making it an exciting, enabling technology, with potential impact across many applications."

Agelbert NOTE: The above research, particularly in regard to pore size and flow rates, is part of the REAL WORLD of thermodynamics that the fossil fuel industry pretends "does no exist"   in their "heat, beat and treat" brute force approach to energy production. Combusting hydrocarbons is one of the most ruinously polluting ways to produce energy mankind has ever come up with. But since the polluters have been able to dump all the SOCIAL COSTS OF CARBON onto we-the-people while they use their ill gotten profits to CORRUPT our politicians, they just can't let go of their love affair with conscience free polluting for short term profit.     

There are MANY solutions to our energy problems that continue to be willfully ignored by our government simply because the fossil fuel industry DOESN'T WANT THEM IMPLEMENTED. No, sports fans, it NEVER had absolutely anything to do with ERoEI, energy efficiency or "cheap" energy sources. It's ALWAYS been about controlling the spigot of energy available to the average person so that these fascist, government corrupting polluters can retain political totalitarian power.

Below, please find, just one of the MANY CLEAN ENERGY solutions to the polluting energy onslaught degrading our biosphere.


The idea is that multiple methods will ensure species survival. It's called putting ONLY A SMALL AMOUNT of polluting fossil fuel eggs in your energy production basket. AND, those hydrocarbons must be obtained cleanly, not through dirty drilling or mining. Only IDIOTS that defend fossil fuels as a "cheap" and "energy dense" energy source are too STUPID and GREEDY to understand that. Have a nice day.
