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

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.

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.”

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.

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.

Agelbert NOTE: If this genius inventor, Lonnie Johnon , had been given the funding he needs, we would no longer have ANY fossil fuel use in our WORLD, not just our country. And that is probably why (this talk is THREE YEARS OLD!) he has had so much difficulty obtaining the multi-million dollar funding he needs to mass produce and market his engine (already recognized as the most efficient engine ever invented!) and battery technology inventions.

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.

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.

GE To Build 344 Megawatt Kokhav Hayarden Hydro Pumped Storage Station In Israel

August 10th, 2017 by Joshua S Hill

SNIPPET:

GE Renewable Energy has landed the contract to supply and build the 344-megawatt Kokhav Hayarden hydro pumped storage station in Israel, which is expected to help stabilize the country’s electricity grid.

On Tuesday, GE Renewable Energy revealed that it had booked a turnkey contract with Israeli utility Star Pumped Storage, in which GE will design, manufacture, supply, and install all the necessary electro-mechanical and hydro-mechanical equipment for the 344 MW (megawatt) Kokhav Hayarden hydro pumped storage station. GE will also complete a balance of plant for the two 172 MW pumped-storage units, as well as provide 20 years of operation and maintenance for the project.

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.

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.

Agelbert NOTE: The micrometre (International spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), is also commonly known as a micron. 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.

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.

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.

Full article:

http://www.zmescience.com/science/asphalt-lithium-batteries-432432/

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.
