WattJoule Corporation, a developer of next-generation liquid electrical energy storage systems, has developed and built a new system demonstrating a major industry cost breakthrough. The new storage platform is called ElectriStor™ and will be offered to system integrators as the preferred core component for storing large amounts of solar and wind energy.
One of the major barriers preventing the widespread adoption of large-scale energy storage has been cost. WattJoule has engineered the ElectriStor™ platform based on the redox flow battery concept where electricity is stored in a liquid. WattJoule's proprietary liquid electrolyte is mostly water, and the company has developed a new, inexpensive process to make it in large quantities. Early liquid energy storage systems have suffered from a number of technical and cost limitations. Recently there have been several technical breakthroughs to overcome these constraints. WattJoule has both developed and exclusively licensed key technologies that, in combination, dramatically lower energy storage costs to $150 per kilowatt-hour in its first-generation energy storage product.

Brady Dennis for The Washington Post: The U.S. wind energy industry had a memorable 2015, from installing thousands of new turbines across the country to supporting a growing number of jobs.
But perhaps one of the most noteworthy brights spots of the past year, according to an annual report released Tuesday by the American Wind Energy Association (AWEA), was the growing demand for wind energy from major corporations. High-tech firms such as Google Energy, Facebook and Amazon Web Services, as well as more traditional companies such as Procter & Gamble, General Motors, Walmart and Dow Chemical, have signed contracts to purchase increasing amounts of wind energy in coming years.
Corporations and other non-utility customers — including some municipalities and universities — accounted for more than half of the wind power capacity sold through so-called power purchase agreements in 2015, according to the AWEA. The group said that corporate and other non-utility buyers have signed contracts for more than 4,500 megawatts of wind power capacity, or enough to power the equivalent of about 1.2 million American homes.

Sam Grobart for Bloomberg: There are 332,519,000 cubic miles of water on the planet. That's 352,670,000,000,000,000,000 gallons just sloshing around out there.
Anyone who's ridden or been tossed by a wave has a sense of the kinetic energy contained in our perpetually moving oceans. If we could harness it, it could provide a clean, renewable source of energy. But efforts to turn our oceans into power generators—often in the form of "aqua-mills," windmill technology adapted to water—have foundered on the complexity of their many moving parts in the corrosive and remote environs of the sea.
A new approach, developed by a company called Oscilla Power, applies all that kinetic energy to a solid piece of metal instead of using it to turn the blades of an impeller. That creates an alternating magnetic polarity in the metal that can be converted into electrical current.
Oscilla's technology, which is nearly solid-state, may prove far more durable than any other ocean-power project, increasing the chance to draw power from our oceans cleanly, meaningfully, and endlessly. View video here:
Adam Vaughan for The Guardian: The amount of household solar power capacity installed in the past two months has plummeted by three quarters following the government’s cuts to subsidies, according to new figures.
A fall in solar power was expected following a 65% reduction in government incentives paid to householders, but the size of the drop-off will dismay green campaigners who want take up on clean energy sources to accelerate.
Data published by the energy regulator this week shows there was 21 megawatts (MW) of small solar installed in February and March this year, after a new, lower incentive rate came into effect. By contrast, energy department figures show that for the same period in 2015, 81MW was installed. Cont'd...
From North American WindPower: According to MAKE’s latest wind power outlook for North America, unprecedented long-term policy certainty in the U.S., along with a new climate-conscious government in Canada, will enable nearly 75 GW of total wind power growth in the region from 2016 to 2025.
The production tax credit (PTC) in the U.S. was extended in December 2015 as a multiyear phaseout and will support a total of 44.4 GW of wind power additions from 2016 to 2021. However, as the value of the PTC phases down after 2018, several drivers must align to sustain wind power growth in the U.S. At the sub-regional level, Texas will lead wind power growth from 2016 to 2018, followed by the Plains and the Midwest.
Turbine technology advancement and balance-of-plant cost reductions will continue to drive down the levelized cost of electricity (LCOE) of wind power and offset a portion of the lost PTC value from 2019. This will allow wind power to maintain a substantial share of new power generation demand, despite attractive costs for natural gas power and rising competition from solar photovoltaics. Last year, the U.S. alone added nearly 8.6 GW of new wind energy generation. Cont'd...
Emily J. Gertz for TakePart: Filmmaker Shalini Kantayya set out to show that climate change isn’t all gloom and doom. The result, Catching the Sun, ably makes that case but may still leave you inspired and infuriated in equal parts.
This fast-paced and compelling new documentary, which premieres Friday in New York City and in cities nationwide during April, follows a diverse group of job seekers, activists, politicians, and entrepreneurs as they tap into the world’s growing solar powereconomy.
Kantayya jumps between nations that have unequivocally adopted policies to speed up adoption of renewables and more fitful efforts here in the United States to expand solar energy—from a program in Richmond, Virginia, training unemployed men and women to become solar panel installers to a “Green Tea Party” member and energy independence advocate working both sides of the halls of power in Georgia.

Ben Walsh for The Huffington Post: There is a “substantial risk” that SunEdison may file for bankruptcy, the world’s largest renewable energy developer said in a regulatory filing on Tuesday. The company’s fall isn’t a referendum on the solar industry as a whole, as much as it is on SunEdison’s aggressive growth strategy fueled by excessive debt and financial engineering, analysts say.
SunEdison “just thought they were smarter than everyone else,” said David Levine, the founder and CEO of Geostellar, a solar energy marketplace that has done deals with the company.
The company’s shares have fallen steeply since they hit a high of $30 in July. They were at just $1.26 before the filing. The stock immediately dropped another 40 percent when the market opened after the filing, and the company was trading at just $0.59 by Tuesday lunchtime.
“What happened from late-2014 to the middle of 2015, the company began embarking on a hyper-growth strategy,” S&P analyst Angelo Zino told The Huffington Post. Cont'd...
James Murray for BusinessGreen: is commonly regarded as a green form of travel, typically boasting lower levels of carbon emissions and air pollution than road transport, but could it also serve to deliver a cleaner and more resilient power grid?
That is the hope of innovative US start up Advanced Rail Energy Storage, LLC, which yesterday announces it has secured a crucial right-of-way lease from the Bureau of Land Management (BLM) to develop its planned 50MW gravity-based energy storage project.
The ARES Nevada project uses the same principles as pumped hydroelectric energy storage projects, but instead of relying on water in a water-stressed region it plans to make use of an inclined rail track and generator locomotive cars that will run along it. Cont'd...
Julia Pyper for GTM: Tesla has quietly removed all references to its 10-kilowatt-hour residential battery from the Powerwall website, as well as the company’s press kit. The company's smaller battery designed for daily cycling is all that remains.
The change was initially made without explanation, which prompted industry insiders to speculate. Today, a Tesla representative confirmed the 10-kilowatt-hour option has been discontinued.
"We have seen enormous interest in the Daily Powerwall worldwide," according to an emailed statement to GTM. "The Daily Powerwall supports daily use applications like solar self-consumption plus backup power applications, and can offer backup simply by modifying the way it is installed in a home. Due to the interest, we have decided to focus entirely on building and deploying the 7-kilowatt-hour Daily Powerwall at this time."
The 10-kilowatt-hour option was marketed as a backup power supply capable of 500 cycles, at a price to installers of $3,500. Tesla was angling to sell the battery to consumers that want peace of mind in the event the grid goes down, like during another Superstorm Sandy. The problem is that the economics for a lithium-ion backup battery just aren’t that attractive. Cont'd...
Sarah Fecht for Popular Science: Currently a high school senior in California, Lewis-Weber has just published a paper in the journal New Space with what he thinks could be the solution to the upcoming energy crisis: putting self-replicating solar panels in space. These solar panels would to build copies of themselves, autonomously, on the surface of the moon. Then they would enter Earth's orbit, collect the sun's energy, and wirelessly beam it to the ground.
That may sound like a crazy idea, but the notion of space-based solar power actually dates back several decades, to the 1970s oil crisis. It was set aside after oil prices went back down, but since then, two things have happened: One, the world has become a lot more desperate to solve climate change; and two, technological innovations have brought this crazy idea out of the realm of science fiction. The idea is gaining attention, and with some big investments, it's possible that space-based solar power could become a reality within a few decades. Cont'd...
SCOTT WALDMAN for Politico: The federal government has designated an 81,000-acre area off of Long Island for possible commercial offshore wind development.
The move by the federal Bureau of Ocean Energy Management on Wednesday to open the federal waters 11 miles off of New York to major wind development projects will be a significant boost to the Cuomo administration’s aggressive climate policies. The Bureau of Ocean Energy Management will now conduct an environmental assessment, with a possible sale of leases to follow.
“New York has tremendous offshore wind potential, and today's milestone marks another important step in the President's strategy to tap clean, renewable energy from the Nation’s vast wind and solar resources,” U.S. Secretary of the Interior Sally Jewell said in a statement. “We will continue to work with the State and local stakeholders through a collaborative effort as we determine what places have the highest potential and lowest conflict to harness the enormous wind energy potential off the Atlantic seaboard.” Cont'd...
Jethro Mullen for CNN: Fed up with their hefty electricity bill, managers at Cochin International Airport in southern India took matters into their own hands.
Three years ago, they began adding solar panels -- first on the roof of the arrivals terminal, then on and around an aircraft hangar. The success of those initial efforts led to a much bigger endeavor.
"We wanted to be independent of the electricity utility grid," Jose Thomas, the airport's general manager, told CNNMoney.
Last year, the airport commissioned the German company Bosch to build a vast 45-acre solar plant on unused land near the international cargo terminal.
The plant came online in August, making Cochin the world's first fully solar-powered airport.
The tens of thousands of panels generate on average slightly more than the roughly 48,000-50,000 kilowatts of power that the airport -- the seventh busiest in India -- uses per day, according to Thomas. Surplus energy is fed into the wider electricity grid.
The big project cost around 620 million rupees ($9.3 million), a sum the airport expects to save in less than six years by not having to pay electricity bills anymore. It also estimates the solar plant will avoid more than 300,000 metric tons of carbon emissions from coal power over the next 25 years. Cont'd...
Peter Maloney for UtilityDive: The U.S. energy storage market put in a strong showing in 2015 with its “best quarter and best year of all time,” according to the GTM/ESA report. And current market trends point toward continued strong growth.
The recent extension of the federal Investment Tax Credit, and new guidelines under consideration at the Internal Revenue Service are expected to further boost energy storage and the pairing of storage with renewable resources.
In the fourth quarter alone, the U.S. deployed 112 MW of storage capacity, representing more than the total of all storage deployments in 2013 and 2014 combined.
For the full year, 221 MW (161 MWh) of storage was installed. In 2014 65 MW (86 MWh) of storage was installed in the U.S. Cont'd...
By PHILIP MARCELO for AP: The offshore wind industry has high hopes for establishing a permanent beachhead in the U.S. after years of disappointment.
Business leaders and politicians who gathered for an industry conference in Boston this week said wealthy investment firms and seasoned European offshore wind companies are increasingly committing to projects along the East Coast. That, they said, is evidence a domestic industry dreamed about for nearly two decades is finally on its way.
"There's a palpable sense that it's finally happening," said Bryan Martin, a managing director at D.E. Shaw & Co. That New York hedge fund is the principal backer of Deepwater Wind, a Rhode Island-based company looking to launch the country's first offshore wind farm off Block Island by the end of the year. "The U.S. tends to start small and ramp up very fast. I believe that will happen with offshore wind."
Among the significant new players to emerge in the past year is DONG Energy, a Danish firm that operates more than a dozen wind farms, including some of Europe's largest. Cont'd...
Joe Carmichael for Inverse: Buffett, in an interview with CNBC on Monday, responded to viewer questions about this clash (a clash that Bloomberg Business intensified with a cover story): two viewers asked why Buffett’s companies are preventing and deterring net metering in Nevada. Buffett responded:
“We don’t have a problem with net meters, and we’re the leading in renewables in the country among regulated utilities. The [unintelligible] we do not want our million-plus customers that do not have solar to be buying solar at 10 and a half cents when we can turn it out for them at 4 and a half cents or buy it at 4 and a half cents. So, we do not want the non-solar customers, of whom there are over a million, to be subsidizing the 17,000 solar customers. Now, solar customers are subsidized through the Federal Government — as we are, with our wind and solar operations ourselves. …
“In Nevada, [Musk's company, SolarCity] had an arrangement for a very limited number of people — and the public utility commission decides this — they had an arrangement where the utility had to pay way above market for solar produced by these 17,000 homes, and that —“
The interviewer interrupted to clarify: “For instance, if I have solar electricity that I’m producing, that’s more than I need, I can sell it back to you…” Cont'd...
