Battery Hackers Are Building the Future in the Garage  ;D

A day trader cannibalized a Tesla to go off the grid. That's the spirit igniting a revolution in solar energy.

Excellent and informative comments. Thank you all.

Thomas M knows the score. But people are not as easily beguiled by the Agnotology that has been par for the corrupt and mendacious course of ethics challenged corporations in general (and dirty energy special interests in particular) for well over a century.

We get it now. And we are spreading the word.

I attended a seminar at the annual meeting of the AAAS (American Association for the Advancement of Science) in San Francisco titled: The Sociopolitical Manufacturing of Scientific Ignorance: Agnotology, organized by Jonathan Coopersmith of Texas A&M University.

The first presentation was a recapitulation of the familiar shenanigans of the tobacco industry plus an account of a creditable science magazine named “Science Fortnightly” that was published for several years apparently motivated entirely to promote Kent Cigarettes. Also I had not heard before that the first Kent filters contained asbestos.

So there were quite a few fronts for the tobacco agnotologists, most notably the George Marshall Institute, very active in downplaying second hand smoke, and a covey of “charitable” foundations providing grants for such fronts.

A useful list of these organizations includes the following:

 The American Enterprise Institute $45,000,000 dispersed 1985-2006

 The Carthage Foundation, $68,000,000 dispersed 1985-2003

 The Cato Institute, operating budget $22,000,000 in 2007

 The Claude R. Lambe Charitable Foundation disperses $28,000,000 annually; it is one of the . . Koch family foundations along with the Charles G. Koch and the David H. Koch Foundations. . Collectively they have contributed $196,000,000, mostly to think tanks, from 1980 to 2009.

 The Earhart Foundation $95,000,000 in assets (major contributor to George Marshall Institute)

 The George Marshall Institute dispersed $5,500,000 1985- 2001

 The John M. Olin Foundation existed 1953-2005 & dispensrd $370,000,000 to think tanks

 The Linde and Harry Bradley Foundation, $290,000,000 in assets

 The Mercatus Center received $11,874,500 1977-2009 from Koch family foundations

 The Sarah Saife Foundation, $235,000,000 dispersed 1985-2003

 The W. H. Bradley Foundation $13,000,000 in assets

Many have morphed into coveys of expert spin doctors practicing agnotology.

Examples of the sorts of projects funded:

1) A commission to study the accuracy of teaching materials used for teaching "environmental science";

2) Senior scientist program to foster "sound science" in policy debate.

It appears that these projects really exist to rebut an established consensus for the benefit of sponsoring clients.

The AAAS presenters emphasized many names recurring as participants in these organizations. The presenters had such lists—useful in evaluating the motives of any new organization not yet known to be a front for agnotology.


What's does Agnotology have to do with suppression of R&D to multiply the efficiency while lowering the cost of batteries and Renewable Energy?

Tesla's residential battery system leaked, here's everything we know 
 By Shawn Knight on April 1, 2015, 10:07 PM

Tesla CEO Elon Musk earlier this week teased a new product line set to debut on April 30. All signs suggest that product will be the home battery system the entrepreneur spoke about during an earnings call earlier this year.

For those needing a bit more convincing, a recent note from Global Equities Research analyst Trip Chowdhry should do the trick.

In it, he claims to know two people that are currently testing Tesla’s residential battery system. One of the two testers was willing to provide a wealth of information on the system (behind the shadow of anonymity, of course). Here’s everything we know from the person that spilled the beans.

There are around 230 homes in California currently testing Tesla's stationary battery as well as another 100 or so outside of the Golden State. The source said he had been using the system for about a year and a half now  :o and that it is installed in his garage.

As for installation, the battery must be installed at least 1.5 feet above the ground and needs to have at least one foot of open space on all sides. The battery doesn’t make any sound, doesn’t require any maintenance and doesn’t leak (good to know).

The unit itself measures about three feet tall and is around 2.5 feet wide. Aesthetically, it “looks good,” the source said.

During installation, he was offered a 10WKH and 15WKH option; he chose the smaller of the two. There’s also an inverter, we’re told.

While final pricing likely hasn’t been decided yet, the customer in question selected a plan in which he paid $1,500 up front and $15 per month over a period of 10 years. After that, the installer will take the system back. Chowdhry suggests the battery could be priced at $13,000 with a 50 percent rebate from PG&E Corporation.

Chowdhry said his source told him the system can be controlled from his iPhone as well as via a web application. His unit is set up to charge from solar panels and once the battery is full, excess energy can be sold back to the grid for a rebate on his electric bill.

Additionally, the user charges the batteries at night when electricity sells for just $0.11 then sells it back to the grid at 3:00 p.m. for $0.43. By doing this, the source said he makes about $10 to $12 per month.  ;D The unit can optionally be charged using a generator, useful during extended power outages due to storms, etc.

Unfortunately, the source didn’t provide any information as to exactly how he uses the battery system outside of selling energy back to the grid.

Cost of Batteries for Electric Vehicles Falling More Rapidly than Projected

Posted April 13, 2015

Keywords: Sustainability, batteries, electric vehicles (evs), Full Spectrum, lithium ion

 Full Spectrum: Energy Analysis and Commentary with Jesse Jenkins

Summary: The cost of battery packs for electric vehicles has fallen more rapidly than projected, with market leading firms in 2014 producing batteries at ~$300 per kilowatt-hour of storage capacity, on par with market projections for 2020.

Electric vehicle (EV) battery costs have fallen more rapidly than many projections, according to a new survey of battery costs published in Nature Climate Change. Researchers from the Stockholm Environment Institute scoured peer-reviewed journals, consultancy reports, and news items to construct an original data set of EV battery pack cost estimates from 2007 to 2014.

Average battery pack costs have fallen 14 percent per year across the industry
, which has seen sales volumes double annually in recent years. EV battery packs now cost $410 per kilowatt-hour (kWh) of storage capacity on average (with a 95 percent confidence interval ranging from $250–670 per kWh).

The cost of batteries produced by market leading firms, such as Renault-Nissan and Tesla Motors, however, have fallen further , to an average of $300 per kWh, according to the study.

These estimates are on the order of two to four times lower than many recent peer-reviewed papers have suggested and already equal to the average cost projected for 2020 in a variety of papers. Costs for market leaders have declined at an average of 8 percent per year, the study estimates.

At $300 per kWh, electric vehicles can begin to compete economically with traditional petroleum-fueled internal combustion engines when gasoline costs $3-5 per gallon (€0.73-1.22 per liter), according to separate analyses from global consulting firm McKinsey and the International Energy Agency. The U.S. Department of Energy (DOE) has set a target of $150 per kWh for battery electric vehicles to become broadly competitive and see widespread market adoption.

In the near-term, the researchers believe economies of scale, improvements in cell manufacturing and learning-by-doing in pack integration, rather than advancements in cell chemistry or other R&D breakthroughs, will help manufacturers continue to produce cheaper batteries.

EV battery sales volumes are current doubling annually and car manufacturers are partnering with battery makers to invest in larger production facilities and cut costs. Renault-Nissan is working with LG to produce enough batteries for 1.5 million electric vehicles per year by 2016 while Tesla Motors and Panasonic are building a “Gigafactory” in Nevada that will produce 500,000 packs for EVs along with additional batteries for stationary energy storage, for a total of 50 million kWh per year of battery production. Tesla and Panasonic are targeting a further 30 percent decline in battery pack costs by 2017, which would require a 7 percent annual decline in costs, consistent with a continuation of recent rates for market leading firms.

The study’s authors conclude that economies of scale are likely to drive down battery costs to $200 per kWh in the near future. Further cell chemistry improvements may be necessary to hit the $150 per kWh target envisioned by the U.S. DOE. At those prices, electric vehicles may soon break out of niche markets and achieve much wider-scale adoption.

    Tesla Unveils Batteries for Homes, Businesses, Utilities   

 Dana Hull, Mark Chediak and Louise Downing, Bloomberg 
 May 01, 2015 

SAN FRANCISCO -- Tesla Motors Inc. Chief Executive Officer Elon Musk unveiled a suite of batteries to store electricity for homes, businesses and utilities, saying a greener power grid furthers the company’s mission to provide pollution-free energy.

“Our goal here is to fundamentally change the way the world uses energy,”   
Musk said at an event Thursday at the company’s design studio in Hawthorne, California.
“We’re talking at the terawatt scale. The goal is complete transformation of the entire energy infrastructure of the world.”
The announcement, after weeks of anticipation, marks Tesla’s expansion beyond electric cars. As homes, businesses and utilities use more renewable energy generated by sunshine and wind, the need to provide reliable power grows. Batteries can be used to store electricity during peak production and dispense it later, when the sun isn’t shining or the wind isn’t blowing. The company’s shares rose 2.6 percent to $232 at 7:11 a.m. New York time before regular trading.

Tesla’s home battery, named “Powerwall,” is a rechargeable lithium-ion battery that mounts on the wall and comes in 7 kilowatt-hour or 10 kilowatt-hour versions, the company said in a statement. Deliveries will begin in late summer at prices starting from $3,000, Tesla said.

The battery is designed to enable so-called “load-shifting” by charging during times when electricity prices are lower due to less demand, and discharging when demand and prices are high. It can also store solar power generated during daytime and release it at night, and serve as backup during outages, according to Tesla. The average American home consumes about 30 kilowatt-hours of energy a day, according to the U.S. Energy Information Administration.

Musk said the home batteries will come in different colors and look like “a beautiful sculpture on the wall.”

Utility Industry

In the utility industry, storage is finally coming of age. In Tesla’s home state of California, a groundbreaking energy storage mandate requires PG&E Corp., Edison International’s Southern California Edison and Sempra Energy’s San Diego Gas & Electric to collectively buy 1.3 gigawatts of energy storage capacity by the end of 2020. New York is also turning to storage to relieve congestion on transmission lines and plans for the potential retirement of aging power plants.

The power industry has struggled to come up with a cost- effective storage solution, an issue that has become more pressing as growing amounts of solar and wind are integrated into the grid.

“Energy storage can be a really large ecosystem,”
Chris Shelton, vice president at AES Corp., an Arlington, Virginia- based power producer and utility owner, said in an interview after Musk’s announcement. “It helps to have another voice, and a prominent voice, making the case.”

More ‘Gigafactories’


Tesla’s utility-scale battery will consist of 100 kilowatt-hour blocks that can be grouped to a scale of 500 kilowatt-hours to more than 10 megawatt-hours.

Palo Alto, California-based Tesla is making a bet that its $5 billion “gigafactory” under construction near Reno, Nevada, will enable the mass production needed to drive down battery costs for both cars and energy-storage products that are already serving as a revenue stream for the company. More such factories will be needed to help make the transition from fossil fuels to renewable energy, Musk said.

Tesla, whose batteries are already supplying large customers like Wal-Mart Stores Inc., Cargill Inc., and Jackson Family Wines, has formed partnerships with companies including Green Mountain Power   to sell its home batteries, it said. The company is also teaming up with Southern California Edison to install batteries for utilities, while Amazon.com Inc. and Target Corp. will pilot use of Tesla’s batteries for businesses.

SolarCity Customers First in Line

Elon Musk will make the device available to SolarCity Inc. customers seeking backup supply when the grid goes down.

The battery “replaces noisy, dirty fossil-fuel generators with zero-emission storage technology,”
SolarCity said Thursday in a statement. SolarCity began taking orders for the Tesla batteries on Friday and expects to begin installing them in October.

GMP to sell new Tesla home storage batteries

John Herrick May. 1 2015, 6:47 pm 6 Comments

Tesla’s Powerwall. Courtesy of Tesla (at link).

Vermont’s largest electric utility announced Friday it is partnering with Tesla Motors Inc. to sell batteries that store solar electricity for residential use.

Green Mountain Power will begin offering Tesla’s Powerwall home battery units to customers this fall in Rutland. The batteries store excess power coming from the grid or net-metered renewable energy generation projects to then be used during an outage or when wind and solar energy is not available.

The batteries can also be recharged at night when Vermont’s utilities pay less for power, and supply power when prices are high during peak demand, a process known as “load shifting.” GMP says it will encourage customers draw electricity from the batteries during peak demand to reduce transmission and capacity costs, which are passed onto customers. The batteries can also be use to power homes during outages.

“This is a great example of how Vermont is leading the way with real-world solutions to a more sustainable future,” GMP President and CEO Mary Powell said. “We want to create a new definition of resiliency, where we move away from the 100-year-old grid system to a new electric system where energy is generated and used closer to home.”  

The Powerwall is a rechargeable lithium-ion battery pack that is mounted on a wall to harness excess electricity. Tesla sells a 10 killowatt-hour for version $3,500 or a 7 kWh version for $3,000. The batteries are warrantied to last 10 years. Tesla says it will recycle the batteries.

The 7 kWh unit can power essential services in a home such as the lights, furnace and refrigerator for about six hours during an outages, according to Kristin Carlson, a GMP spokeswoman.

She said 80 percent to 90 percent of the utility’s outages last two hours or less.

GMP will receive its first Powerwalls in October. It will distribute 400 to customers in Rutland and later statewide. GMP will offer product incentives combined with on-bill financing, the company says.

Carlson said the company aims to charge customers between $3,500 to $4,500 for the battery, an AC-DC inverter and installation. She said the company can subsidize the batteries because they could reduce peak power costs to the utility.

After the 10-year life of the battery, Tesla will pick up the battery from the customer and recycle it, Carlson said.    

Tesla announced its home storage system Thursday in California.

Of course the recycling promise completely depends on the continuation of Tesla Motors as a going concern, and there is exactly one company in the US (maybe in the world, not sure) that recycles LI-Ion batteries. (Toxco)


I hope they do keep going, as someone who is on his second car with batteries (first with LI-Ion since the Prius has NiMH's) but I'm not counting on it. Ten years is a long promise. I still think Edison cells make better sense for home power. The power utilities should subsidize those.

When lithium-ion batteries reach a recycling plant, there are two ways to pulverize them. If they are completely without a charge, they're simply shredded so that the metal components, like copper and steel, can be easily sorted out. If the batteries could still possibly have a charge, though, they're frozen in liquid nitrogen and smashed to frozen bits (cool!). The liquid nitrogen is so cold, the batteries can't react, so the smashing is safe. And probably fun. Then the metals are separated out for reuse.

I think you are right in regard to PUBLIC ACCESS battery technology. But the importance of this move by Tesla goes far beyond the limits of battery technology BECAUSE it is a paradigm shift in thinking about energy that the "dirty energy is the only reliable energy" people DO NOT WANT us to think about.

The assumption most people HERE started out with when I began posting about renewable energy 3 years ago was that NO WAY, JOSE for renewable energy's "drop in the bucket".

Look how things have changed in just 3 YEARS. It's over for dirty energy, Eddie. THAT is the subtext. THAT s what I am celebrating. THAT is what relegates all the "math doers" claiming this, that and the other about the "viability" of fossil fuels SQUARELY to the fringe whacko group that THEY had previously brainwashed MOST PEOPLE HERE into believing was applicable to the Renewable Energy crowd.  :icon_mrgreen:

The unleashing in the next ten years of just a tiny portion of all the suppressed (by the fossil fuel government for nearly a century) renewable energy technologies, of which battery technology is a small segment, is now happening.

The Renewable Energy Revolution will not be stopped this time, UNLESS we have a global thermonuclear war. So, yeah, the fossil fuelers have a genuine MOTIVE for wanting ALL OUT WAR. Never mind that it will hasten our extinction. Those people have been nuts from the start. I have yet to convince most people here of that, as well. But nevertheless, people are starting to connect the war loving, suicidal psychopath "dots" to the fossil fuel government/lobby MO. I hope it's not to late to stop those crazies.

The "DIRTY ENERGY IS THE ONLY RELIABLE ENERGY" folks will soon be singing "I'm on the outside looking in."        

There are ALL SORTS OF NOVEL ideas popping up out there!       
 Consider your place in Texas. Consider that you DO HAVE the solar power and money to buy umpteen panels that YOU KNOW will last 25 years PLUS with almost ZERO maintenance.  :emthup:

Suppose you just use the bulk of them to pump water into a huge tank. THAT TANK IS A BATTERY! That battery has INFINITE "charge" cycles, Eddie. That BATTERY NEVER NEEDS TO BE "recycled"!

And how do you get juice from that "battery" at EXACTLY the right voltage and amperage? 


Here's a tiny one. It's very quiet and certainly won't power most of your needs but it is a NO BRAINER that this technology is SIMPLE and is EASILY scaled up to get your 15KW or so household demand 24/7 come hell AND high water.

And I don't need to tell YOU, in dry Texas, what ELSE you could do with access to a LOT of stored water, do I?   


And, by the way, if large water towers are not your cup of tea, a GIANT water tank can be placed IN THE GROUND (out of sight and out of sabotage access by vandals ;D) with a gravity powered weight pushing DOWN on the water to give you water pressure for your generator. This is a build and forget thing with zero maintenance, for all practical purposes.

Many systems, up to the gigawatt generating level of underground giant cylindrical weights in multiple cylindrical tanks have been proposed. NO ADDED WATER is necessary after initial fill up. You just raise the weight when you have excess solar power, PERIOD. Of course, the fluid does not have to be water, but I think water is the best to protect the environment in the case of minor leaks.

Think BIG, Eddie. It ain't over yet!

SunEdison Recruits Imergy Flow Batteries for Microgrid Rural Electrification Initiative

After a pledge to power more than 20 million people in rural India, SunEdison has partnered with Imergy to install hundreds of solar-powered minigrid systems.

 Meg Cichon, Associate Editor, RenewableEnergyWorld.com 
 March 25, 2015  |  8 Comments 

Massachusetts, USA -- Earlier this year, SunEdison announced a goal to bring power to 20 million people in rural India by 2020. To forward this mission, it announced today that it will use more than 1,000 flow batteries from Imergy Power Systems for its solar-powered minigrid projects.

The solar-powered minigrids are anchored to telecom towers near remote villages with batteries typically ranging from 30 to 120 kWh. The system provides 24/7 power for the tower, while also powering surrounding villages. Instead of purchasing expensive kerosense or simply living in darkness, villagers are able to charge their devices or wire lighting to the village itself. According to Imergy CEO Bill Watkins, about 5,000 villages fit this telecom model.

Imergy is no stranger to off-grid applications. It’s storage technology has already been installed in both India and several parts of Africa. While in the U.S., the Navy is currently testing its applications in a smart microgrid project.

Its technology uses recycled vanadium from environmental waste, which is stored in tanks and circulated during charge and discharge cycles.  Since the chemicals are stored in separate tanks, the system can be scaled up or down fairly easily. And while flow batteries have a shorter response time than other battery technologies, they are ideal for off-grid applications, according to Tim Hennessy, Imergy President and COO.

“We can scale energy. If you’re looking to store it for 24 hours, you can’t do it with other batteries or costs would become exorbitant,” said Hennessey. “There is no software to manage, a deep charge lasts all day long, and it can withstand harsh environments.”

Back in December 2013, Imergy told REW that its costs were on track to reach $300/kWh by 2015. Hennessey said that they are still on track for that number to become a reality, but emphasized that the industry needs to look at the levelized cost of energy to understand true costs.

“Everyone talks about costs, but the fact is that [vanadium flow batteries] will last 20 years on energy storage cycle, and vanadium itself never wears out. While lithium-ion batteries may be ‘cheaper,’ they have a much shorter lifespan and are less scalable,” said Hennessey. “We are actually cheaper than other technologies over the lifetime of a battery.”

But while everyone is interested in the technology and economics, Watkins and Hennessey want to emphasize the importance of these rural electrification projects.

Hennessey explained what he called the “battle of the last mile.” When industry cannot justify extending transmission an additional five miles, many villages are left in the dark. However, when the villages get off-grid power, businesses start to crop up and demand increases, which then eventually justifies transmission investment. But since India’s transmission system is so unreliable, these villages are now relying on renewable energy systems, which are creating huge economical growth.

“The big picture here is the fact that so many people in this world don't have electricity. When we enter these villages, it gets very emotional — most of them has never seen electricity in their lives,” Imergy's CEO Bill Watkins. “Yes, of course we want to make money for investors, but this is a big deal…This is a way to reach these people and have them be a part of the world — we can’t even fathom the impact.”

Tesla Energy: Will the Markets for Solar and Storage Include Everyone in Need?

 Lewis Milford 
 May 04, 2015  |  2 Comments 

Elon Musk’s Tesla Energy announcement to sell an affordable, reliable battery system for solar energy storage in homes and businesses is more important than all the hyped press even suggests. But as extraordinary as the news is about how this technology will impact our energy future, it leaves out some important issues still to be sorted out.

At the top of the list is how these technology advances will benefit people other than high-income homeowners and businesses who are likely to be the first adopters of the product — how to make these technologies available to the low- and middle-income people who also need resilient power.

The news of Tesla opening up a new energy battery division, called Tesla Energy, has captured the headlines and the imagination. In a presentation reminiscent of Steve Jobs before an adoring crowd, Musk gave an entertaining and direct talk about the need for solar and battery storage to replace fossil fuels and address climate change and to capture and store electric power that can make homes and businesses more resilient and independent from the power grid. It was an impressive show.

The product specifications are even more impressive. For a cutting-edge and innovative product, the cost is low for a home system, $3,500, with an inverter and installation adding to that cost. That system will allow a home or business to island, to go grid independent in case of a power outage. It will also enable customers to reduce electric bills, especially very high demand charges that can represent more than half of typical commercial electric bill.

The announcement is part of a wave of good news about how solar plus battery systems can reinvent the power system, reduce pollution, and realign the relationship between electric utilities and their customers.

But what is missing from this news is how new battery storage technology can improve public safety — in virtually all buildings that protect the public like fire and police stations, schools and hospitals; and how this technology can benefit the people who need access to low-cost and resilient power the most — the underprivileged and largely forgotten poor, many who already suffer high electric bills in places like affordable housing and assisted living facilities. We need to ensure that the larger public and the most vulnerable can get these technology benefits along with high-end homeowners and businesses.

Social equity is often a challenge during these new technology transitions — the need to ensure that the arc of these new and cleaner solar+storage technology markets benefits the general public rather than only private commercial customers and the affluent.

We need to direct these technologies to benefit all sectors of society — not as an afterthought, but from the outset, as a matter of foundational market and policy design. That has not been the case with clean energy markets — the poor have usually been left behind the technology curve.

As these energy storage technologies become available, we need to make sure they are deployed to provide resilient power to communities, to make sure that emergency services and public infrastructure can benefit from reliable and affordable solar plus storage technologies. Hospitals, schools, water treatment plants, fire stations, elderly housing complexes, airports, communications and transportation systems could all benefit from these technologies. They all need reliable and affordable electric power; they all need to function when the grid goes down.

The good news is that Tesla seems driven to serve both private enterprise and public benefits. Musk is a brilliant energy innovator with a desire to solve large societal problems like climate change. He is keeping his technology patents open. That is to be commended.

What is also needed now is a commitment to ensure that new energy storage markets also include the public sector — to extend these economic and environmental benefits to the people most in need now, and not have these benefits trickle down years later, after the technologies have become mainstream.

The conversation about how to make that happen is an important one that companies like Tesla need to have.

Where has your voice for "social equity" been for the past decade or so while the costs of fossil-fuel energy doubled for everyone, placing the greatest burden on the people most in need? Solar and wind power - and technology to store solar and wind energy - promise strong elements of price stability and predictability for everyone, including the economically disadvantaged. Fossil fuel energy and its inherent price volatility, unpredictability and massive subsidies are far more serious problems for the poor than anything that could be envisioned for modern clean energy technology.

Of course Renewable Energy should be made available to everyone. This is where the insidious nature of town ordinances comes in. NOBODY seems to want to ADMIT that the infrastructure, at present, is tailored to promote the use of fossil fuels in homes and businesses and make it rather challenging, to put it mildly, to install Renewable Energy.

No town ordinance will stop you from doubling the size of your fossil fuel burning furnace or installing a giant electricity hog called a central air conditioning system.

Yet, just try to dig up the land to install a geothermal loop or stick a large PV panel array on your lawn (because you want easy access to it). How about the distance from the road that you are required, by ordinance, to put up a tower for a wind turbine? Be prepared to jump through several hoops, including peculiar ideas of what is aesthetically acceptable and what is not.

People say this is just common sense. NO IT ISN'T. It's a deliberate defense of an unsustainable energy status quo, period. Hello, Colchester, Vermont. Are you listening? I am certain that there will be some bureaucratic baloney thrown at the Tesla Wall Battery, regardless of the fact that it is unobtrusive. The old "licensed electrician must provide an annual inspection of LARGE battery systems (see the Tesla battery stats LOL!)" trick to generate local jobs for friends of town counselors comes to mind.

All Renewable Energy installations should be protected from town ordinances by Federal Law. But, of course, our bought and paid for "democracy" hasn't gotten around to that, for some reason...

Change is coming IN SPITE OF irrational and environmentally suicidal town ordinances. The fossil fuel government at every level will not let go of its gravy train easily. But it will, eventually, be forced to.

But for now, the poor are basically OUT of the Renewable Energy loop BY profit over planet, predatory capitalist DESIGN.

100% of the people could have 100% Renewable Energy if the Federal Reserve provided loans for Renewable Energy Systems at the same low interest rate set for home mortgages. It's really stupid that they don't. The massive number of jobs generated from this giant transition would boost GDP. But some rich pigs would lose profits. So it is not done. So it goes..

Ancient Greek Energy Storage Technology Challenges Tesla's Batteries

 Jeremy van Loon, Bloomberg 
 May 06, 2015

CALGARY -- A technology used in ancient Greece to power clocks and fire a cannon is undergoing a revival as the world searches for better ways to store energy from wind turbines and solar panels.

Compressed air, already used to power carnival rides, jackhammers and medical equipment, joins the crowded field of innovations chasing what may be a $21.5 billion market in 2024.

Compressed air auto Citroen drive train

Contenders include Elon Musk, chairman of Tesla Motors Inc., who this month unveiled a suite of batteries to store electricity for homes, businesses and utilities.

While Tesla plans to begin delivering its rechargeable lithium-ion model in late summer, compressed air storage systems, or CAES, may have an edge.
The technology can be used to store large amounts of power for weeks at less than the cost of batteries.

“You need bulk storage to support all the renewables and CAES is pretty much the only technology to do that,” said Jim Heid, vice president at Dresser-Rand Group Inc., a supplier of compressed air products. “It’s a worldwide phenomenon because of all the intermittent renewables coming online.”


The mechanics are simple. Start with electricity from wind turbines and solar panels to run compressors that fill man-made caverns also used for natural gas storage. When the pressurized air is released, it drives turbines that provide clean power when the sun doesn’t shine and the wind doesn’t blow.

In less than a decade, annual investment in compressed air will be almost $5 billion, according to Navigant Research. That will support more than 11 gigawatts of installed capacity and help renewable power developers match demand with supply.

Competition is stiff. Along with batteries, developers are using everything from vats of molten salt to rooftop tanks filled with ice to store energy, a market Navigant sees expanding about 35-fold by 2024 from $605.8 million this year.

Improvements Needed

Even supporters acknowledge that air storage needs to improve. The systems currently return only about 60 percent of the power used to fill caverns, according to Dresser-Rand.

“When you put in one unit of energy, you want to get one unit out,” said Sam Shelton, senior fellow at the Strategic Energy Institute at the Georgia Institute of Technology. “Air is not very dense so compression storage is low efficiency. It’s all economics.”

Advancements in technology will boost efficiency and eliminate the need to heat the pressurized air with natural gas, reducing carbon dioxide emissions. Developers are improving above-ground vessels for smaller-scale applications.

“Overall it’s a market that has a couple of niches,” said Brian Warshay, an analyst with Bloomberg New Energy Finance in New York. “A lot depends on the location and the proximity to demand.”

Two years ago, California regulators asked the state’s three biggest utilities to add 1.33 gigawatts of energy-storage capacity by 2020 -- about 20 percent more than currently exists in the world, excluding pumped hydropower systems.

Rooftop Ice

Spain’s Abengoa SA is developing a solar-thermal project in California that will incorporate power storage. Ice Energy Holdings Inc., a Santa Barbara, California-based company, is pioneering a storage method using rooftop ice to provide cooling during the day.

The Greek inventor Ctesibius wrote studies on the science of compressed air in the third century BC. The technology was used in an alarm clock, a cannon that shot arrows and to open the gates at the Temple of Alexandria.

Thanks to its scale, compressed air storage today offers a solution to a challenge facing grid operators -- how to store wind power at night when demand for electricity slumps, and solar power for cloudy days.

Compressed air can store hundreds of megawatt hours of electricity for weeks at a time. Batteries are useful for smaller volumes for shorter periods, said Rocco Vita, director of emerging technology at pipeline company Enbridge Inc., which operates solar and wind farms across North America.

Texas Wind

Chamisa Energy, based in Santa Fe, New Mexico, is seeking to raise about $400 million to build a compressed air project in the Texas Panhandle that can store wind energy at night and release it when turbines are still.

“We’re surrounded by some of the best wind in the U.S. and the wind often blows in the off-peak,” said Alissa Oppenheimer, managing director at Chamisa. “There are numerous times of the day when the price of wind is negative.”

Investors, who may not understand the advantages of the technology or are concerned that air storage systems are inefficient, have been slow to commit, Oppenheimer said.

Dresser-Rand built one of the world’s two commercial compressed air systems in Alabama in 1991 and is currently working on other projects in Texas, said Heid. In Alabama, Power South Energy Cooperative’s 110-megawatt system stores enough energy from nearby power plants to power 110,000 homes. The world’s first commercial application of the technology was in Germany in 1978 with a 290-megawatt plant.

Surplus Energy

In Canada, Ontario’s grid operator wants to add 16 megawatts of storage, including CAES, to cope with a supply surge from wind turbines and solar panels.  ;DNRStor Inc., which is bidding for the contract, expects the efficiency and cost of air storage to improve.

Were Ontario to add 1,000 megawatts of compressed air storage, consumers would save C$8 billion ($6.6 billion) over 20 years, said NRStor Chief Executive Officer Annette Verschuren. With the system she’s proposing, stored air could turn turbines for as long as 300 hours.

“Ontario has really built up a lot of renewable energy and is building up a lot more surplus energy,” Verschuren said. “We would capture the night stuff, capture the weekend stuff and put the energy on the grid during daytime.”

NRStor sees the price of compressed air systems falling fall to one-tenth that of the expected $350 a kilowatt hour cost of battery storage in 2022, said Verschuren. She declined to say how much the Ontario project will cost.

Is Compressed Air Energy Storage (CAES) Scalable? Scalability is actually what makes CAES cost effective. IOW, YES!

Compressed Air Energy Storage

Agebert NOTE: VERY brief summary of this educational chapter. I did not crunch any numbers. The math is above my skill set.  :(  But I can read graphs and English quite well.  ;D


CAES storage reservoirs for underground storage can be classified into three categories: salt, hard rock, and porous rock. These geologies are found to account for a significant fraction of United States (Fig. 2). Previous studies indicate that over 75% of the U.S. has geologic conditions that are potentially favorable for underground air storage [18]. Fig. 3 (at link) shows different storage mediums throughout US.


Currently the major drawback for CAES is its dependability on fuel source for the power generation. Natural gas prices contribute to the economics of CAES. Like any energy conversion system CAES also has its share of losses, thus working with an efficiency percentage around 60 % to 70 %. Some of these backlogs in CAES technology are currently overcome by enhanced CAES configurations and concepts. These advancements are given in a later section.


The CAES model developed is able to capture the influence of storage reservoir dynamics on performance measures such as demand met and input spillage percentage. From Fig.12, it is seen that irrespective of turbine and compressor sizing, a good enough reservoir volume is required to ensure effective addressing of wind variability issues by CAES for this particular wind farm.


We can notice that as the maximum pressure limit increases, the revenue per year and the operational performance measures too increase. So it corroborates the model‘s ability to account for internal storage dynamics and their direct influence on CAES operational and economic outcome.

Since the model has the ability to simulate CAES operation for longer periods of time within reasonable simulation time while also capturing finer second-second or few minutes variations, it could enable performing very finer sub-hourly, say 5-mins, unit commitment studies. Therefore the model can lend itself well in long term production costing studies to evaluate generation planning strategies.



In IEEE 24-bus Reliability Test System (RTS) wind and CAES were integrated and production costing studies were conducted. The production costing study is an hourly simulation for 48 hours (2 days). The data for load and wind generation is taken from Bonneville Power Administration (BPA) for Nov 2nd and 3rd in the year 2010. This data was chosen as it covered good variation in wind pattern. The program was developed using MATLAB with TOMLAB optimization platform.


The production costing study was done with 25% wind capacity penetration with wind farms at bus 17, 21, and 22, and a CAES at bus 21. The turbine rating is 50 MW, compressor is 50 MW and the storage reservoir is 200 MWh.The system contains various mix of generation facilities such as 7 coal generation plants, 2 nuclear generations, 3 natural gas generations, 2 oil fired plants with variable ramping rates, with CAES being the fastest ramping unit. The total system generation without wind generation and CAES unit is 3400MW.

We can observe from Fig. 12 that during high wind spell of the first day the compressor reduces the wind spillage by charging the CAES reservoir, and thereby contributing to down-regulation and earning revenue from the ancillary service market. CAES also participates actively in providing spinning reserves and up regulation, as seen from the plot for turbine.

From the above figures (in addition to figure 12 there are others at the link) it confirms that with increase in wind penetration CAES gains greater benefits from the grid operations.

On the other hand, it is important to quantify how the grid benefits by the installation of CAES unit.

Some of the metrics to quantify the grid benefits are

system production cost,

wind spillage percentage,

quality of regulation,


transmission congestion relief,

system stability improvement and so on.

CAES sizing is a key issue that influences the grid benefits as observed from Fig. 15 (at link). In Fig. 15 as the CAES sizing is increased the wind spillage is reduced. At 10% wind capacity penetration it is observed that the grid without CAES had 4% of wind spillage and with increased CAES size the spillage was reduced to nearly 0.5%. The blue curve in Fig. 15 shows wind energy penetration for corresponding wind capacity penetration in the system. It would be interesting to investigate the correlation between the CAES sizing, and wind energy penetration.


In this chapter, a state space model for compressed air storage technology was developed, which monitors the storage dynamics at any instant of time in terms of the reservoir pressure and mass of compressed air stored.

The model was validated using the operational curves from Huntorf CAES. The CAES model developed is simulated as a collocated facility to address the wind variability issue of a particular wind farm. The model facilitates capturing storage dynamics‘ influence on CAES‘s operational performance and economic indices. Eventually some standard CAES configurations consisting of variations in turbine, compressor and reservoir ratings are simulated and a wide range of performance indices are computed for assessing the worth of each configuration for that particular geography.

From the results we understand that such a venture would require huge investments with very long payback periods. Thus CAES acting as an auxiliary support for individual wind farms may not be as wise as investing in a system level CAES with higher capacity.

Economic assessment of the storage benefits was studied with the CAES model developed and incorporated into the production costing program. The assessment platform with the unit commitment and economic dispatch program modules dispatched the CAES unit under increasing wind penetration levels.

From the results we  observe that CAES plays a vital role in the ancillary and reserve markets with increasing wind penetration, thereby benefitting grid as well as earning revenue to cover its huge investment costs.

The profits earned by the CAES indicate that this venture would be lucrative with the changing grid scenarios involving increasing integration of variable generations. The study points to an interesting direction that the CAES compressor providing down regulation service is especially effective in absorbing the high wind spells, and thus reducing wind spillage and providing economic and quick ramping regulation service to the grid.

Storage‘s participation in ancillary services is attractive because the new generation portfolio not only requires more regulation services, but also higher ramping capabilities and more operating reserves to counter the costs associated with deeper and more frequent cycling of fossil units.

Agelbert NOTE: This is from SPARK, the newsletter of the Rocky Mountain Institute. It was written just before the Tesla Battery announcement but it has great info on how to get the most out of the Tesla residential and business Battery.

There is nobody that can make better use of new technology to reduce (and eventually eliminate) dirty energy better.

The 10 Things Likely To Be Missing From Tesla’s Stationary Storage News

Later today Tesla Motors is expected to make a major announcement about new stationary storage offerings—both a home battery and a very large utility-scale battery. Everyone, it seems, has been abuzz for days, evidenced in wall-to-wall coverage from Bloomberg to Yahoo!. Investment analysts have been weighing in, too, and Tesla’s stock is up significantly this week on the forthcoming news.

Without speculating on the product’s technical specifications or other details we won’t know until Tesla makes the actual announcement, I think we can safely assume that Tesla’s talking points will follow a general three-point outline:
•Stationary storage—including behind-the-meter—is here for the long haul
•Storage has gotten very cheap (or will soon, thanks to the Gigafactory)
•Storage offers value to residential, commercial, and utility customers today

For residential and commercial customers, Tesla’s announcement is another proof point that cost-effective, customer-sited solar-plus-storage systems are coming, as we recently analyzed in The Economics of Load Defection.

However, an obsessive focus on cheap storage for customers risks missing the bigger opportunity. For batteries to be truly transformative—for customers and the grid—we need to recognize the full range of values they can provide and remove barriers (especially market participation) preventing customer-sited batteries from providing all of those values.

Twelve Services Energy Storage Can Deliver to the Grid

For sure, Tesla’s new systems will be used for backup power. They’ll also be used to lower customer bills through arbitrage against rates (such as demand charges) and demand response programs, as many other energy storage companies currently do. But without even knowing additional detail about the product itself, I can safely say that Tesla’s new product will able to do much, much more for multiple stakeholder groups including customers, utilities, and independent system operators (ISOs) / regional transmission organizations (RTOs).

In fact, when products like Tesla’s are installed behind the customer meter and networked with hundreds or thousands of other similar systems, storage is capable of providing about a dozen services to the electricity system at large. Furthermore, in many cases, it costs less for aggregated behind-the-meter storage to provide these services than what we pay for them to be delivered now in other ways.

The services energy storage can deliver when installed behind the meter like Tesla’s planned products fall into three categories: 1) services for customers, 2) services for ISOs / RTOs, and 3) services for utilities.

Services for Customers

•First, they can be used to directly benefit customers by:

•Providing backup power

•Reducing demand charges

•Optimizing customer bills against time of use or other non-volumetric rates

•Increasing self-consumption of distributed solar energy.
In places like Germany and Australia where net metering doesn’t exist or in some corners of the U.S. where electricity is expensive and net metering isn’t available, storage can be used to increase building-level self-consumption from a distributed solar system to maximize the economic benefit of solar. 

These services, especially the first two, are likely to be squarely in line with what Tesla and its partners will announce as major values of their new battery product. However, these customer benefits tell only part of the story; an exclusive focus on these aspects of Tesla’s (and others’) batteries will miss the bigger story and a bigger opportunity.

Services for ISOs / RTOs

Second, storage—especially fast-response batteries like the chemistries found in electric vehicle batteries—can support the grid by delivering a suite of ancillary services. In restructured states like California, this means energy storage can bid into wholesale electricity markets. In non-restructured states like Colorado, these services are delivered using assets directly controlled by the utility—not a marketplace.

These services include:

•Frequency regulation

•Spinning and non-spinning reserves

•Load following / energy arbitrage

•Black start

•Voltage support

In many cases, batteries can provide these services more reliably and at a lower cost than the technology that currently provides a majority of them—thermal power plants—so by using energy storage to deliver these services, some electricity systems can be maintained at a lower cost.

Services for Utilities

Third, storage systems installed behind the customer meter can be dispatched to provide deferral or adequacy services to utilities, such as:

•Transmission and distribution upgrade deferral. When load forecasts indicate transmission or distribution nodes will exceed their rated load carrying capacity, incremental investments in energy storage can be used to effectively increase the node’s capacity and avoid large, overbuilt, expensive upgrades to the nodes themselves.

•Transmission congestion relief. At certain times of the day, ISOs charge utilities to use congested transmission lines. Discharging energy storage systems located downstream of congested lines can avoid these charges.

•Resource adequacy. Instead of using or investing in combustion turbines to meet peak generation requirements, utilities can call upon other assets like energy storage instead.

In the U.S. alone, we’re slated to spend an estimated $1–2 trillion over the next fifteen years on electricity infrastructure. By deploying energy storage—along with demand response, energy efficiency, smart controls, and distributed solar—many of these investments can be avoided in the first place, saving money for society along the way.

Barriers to Market Participation

There’s little argument that systems like Tesla’s, when installed behind the customer meter, can technically deliver these services to the electricity grid. However, even though in many cases behind the meter energy storage—in addition to demand response and distributed solar PV—can provide these services at a competitive cost, several regulations, laws, and misunderstandings have largely restricted the ability of the technology to do so.

In Tesla’s home state of California and in a select number of states like New York, Texas, and Minnesota, regulatory reform efforts are under way that should help overcome many of these challenges.

But until those efforts are successful, these barriers currently restrict behind-the-meter storage to delivering a much shorter list of the services outlined above—even in states leading the charge for electricity system regulatory reform. Encouragingly, even with a truncated list of services to work with, Tesla will still be able to use its new product and create value for thousands of customers including commercial customers looking to reduce their demand charges and residential customers under dynamic rates. In fact, by deploying their new product to deliver only one or two of the twelve services energy storage is actually able to deliver, Tesla will demonstrate the value that their systems can create for the electricity system at large. This act will help overcome myriad regulatory challenges and utility misconceptions facing energy storage by pointing to real-world successes.

A Path Forward

Tesla won’t be alone in working to overcome these barriers to unfettered market access for energy storage and other distributed energy resources. Groups like the Electric Power Research Institute have research and analytical tools coming down the pipeline that will help to illustrate what batteries like Tesla’s can do for the system, and at what cost. And later this summer RMI will be releasing new research as well, including a body of work focused on quantifying the costs and benefits of behind-the-meter energy storage to the grid.

Through these efforts and with the availability of new products like Tesla’s in the marketplace we hope to provide tangible evidence to decision makers on the merits of distributed energy resources and the changes that need to take place in order to unlock their full potential.

Tesla's New PowerWall Battery Sells Out! :o  ;D
SustainableBusiness.com News

Calling the response "overwhelming" and "crazy" Elon Musk says Powerwall batteries are already sold out through mid-2016.

Within days of announcing the launch of Tesla Energy, the company has 38,000 reservations for Powerwall - the home version of the battery. And since most people ordered more than one battery, the sales add up to more like 50,000-60,000.

There's also lots of interest on the industrial/ utility side for the larger version, called Powerpacks  . There are 2500 reservations for about 10 Powerpacks each, for a total 25,000 .

Tesla also received 2,500 requests from distribution and installation companies.

Musk said all this on a call with investors on Tesla's first quarter results, but spent most of the time answering questions on Tesla Energy. The Gigafactory in Nevada - which comes online in mid-2016 - could be devoted to just these batteries, he says, indicating that this first factory won't meet demand.

He expects demand for these batteries to be double that for electric cars.

Fossil fuel produced energy WILL NOT BE USED to operate the above Battery Factory. 

In the first quarter, Tesla sold 10,030 Model S cars - 55% more than Q1 2014 - with revenues of $1.1 billion and a loss of $159 million. Its Model X SUV goes on sale late this year, followed by a lower priced Model S in 2017 ($35,000).

For background, read our article, Tesla's Next Goal: Transform How We Get Electricity.


For businesses and utilities, Tesla Energy offers "Powerpacks   ," more powerful versions of the home-based system "designed to scale infinitely."    They integrate lithium batteries, power electronics, thermal management and controls into a turnkey system.

Powepacks are being piloted in over 100 projects, including Amazon Web Services data centers, Target and Walmart stores and Green Mountain, Southern California Edison and other utilities.

Incredibly, Musk plans to make its battery patents available for free as he has done for the electric car.  ;D
