New Report Finds Thermal Energy Storage Could Add Value To Solar Energy
A new report from NREL, the National Renewable Energy Laboratory, could help spur the development of more utility scale concentrating solar power plants with thermal energy storage features while boosting the market for solar cells, too. The report indicates that CSP/energy storage projects could add value to utility scale solar energy in California, and they would enable more solar cell development by creating additional grid flexibility.
California’s ambitious renewable energy goal for 2020 also plays a key role, so keep in mind that the NREL added-value findings for thermal energy storage are transferable to only to other states with similar aspirations.
WINNERS OF THE INTERSOLAR AWARD 2014 AND THE ELECTRICAL ENERGY STORAGE (EES) AWARD 2014
Intersolar Europe, the world's largest exhibition for the solar industry and its partners, pays tribute to the solar industry's innovative strength for the seventh time. The ten most innovative companies were honored during an official ceremony that took place today at Intersolar Europe's Innovation Exchange. The Intersolar AWARD was presented to groundbreaking solutions in the categories of Photovoltaics (PV) and Solar Projects in Europe. For the first time, the electrical energy storage (ees) AWARD recognizes innovations in battery and energy storage technology.
This year, around 3,500 companies from all international Intersolar exhibitions and the electrical energy storage (ees) exhibition were invited to impress the jury with their innovations. Applicants could only put forward products, projects, services and solutions which were undergoing testing, which were already in use or which showed significant developments to existing technologies at the time of submission. All solar projects had to have been completed within the last two years. The assessment criteria reflected the challenges posed by the market. Experts examined the degree of technological innovation, the benefit for industry, the environment and society, the economic viability of the solution and proof of its innovative quality.

EnerVault unveils 'flow battery' for solar energy storage
In an almond orchard outside Turlock in the Central Valley, two large tanks hold water, minerals - and more importantly, energy.
The tanks in Stanislaus County are part of a "flow battery" that stores energy from nearby solar panels. It's the largest battery of its kind in the world. And it could play a role in California's push to develop bigger and better ways to store large quantities of energy.
This particular flow battery, unveiled to the public Thursday during a ceremony with state and federal officials, was built by EnerVault of Sunnyvale, part of the Bay Area's fast growing energy-storage industry. Like most of its competitors, EnerVault is young, founded in 2008, with about $30 million in venture funding to date.
Some companies try to perfect the lithium-ion batteries found in laptops and electric cars. Others, including EnerVault and Primus Power of Hayward, specialize in flow batteries, which store energy in tanks of electrolytes. The fluid is then pumped through the battery's cells when power is needed. In contrast, the batteries found at a grocery store contain the electrolyte, cathode and anode all in one package.
"Flow batteries are batteries turned inside out," said Jim Pape, EnerVault's chief executive officer.
His company's flow batteries use iron and chromium, blended into the water inside its tanks. Both materials are safe to handle. (For those of you thinking "Erin Brockovich," EnerVault uses the kind of chromium found in multivitamins, not the infamous hexavalent chromium featured in the movie). Iron and chromium also have the benefit of being cheap.
