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.  Full Release:

The Smart Grid And Multifamily Dwelling Challenges

We need to apply good systems engineering principles to policy creation to address the benefits gaps that confront multifamily stakeholders today.

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.

Trees go high-tech: process turns cellulose into energy storage devices

The new approach just discovered at Oregon State can produce nitrogen-doped, nanoporous carbon membranes - the electrodes of a supercapacitor - at low cost, quickly, in an environmentally benign process.

Finding Solutions For Battery Sulfation Issues In Renewable Energy Applications

While the recent news about carbon has been touted as something that can drastically improve the overall performance of the flooded lead acid battery, the facts should be completely understood before buying these types of batteries with any carbon additives, especially if they are sold as a value added feature.

US Battery - Solar RE L16XC Renewable Energy Battery

US Battery - Solar RE L16XC Renewable Energy Battery

Our batteries have Xtreme thick plates with (XC Diamond Plate Technology) added to them. They have been designed for hours of heavy discharge each day, followed by a fast recharge during the daylight hours. Very few batteries can take the grueling deep discharge-recharge cycle every day for long periods of time. U.S. Battery has proven time and time again that our solar battery line can stand up to this type of battery torture day in and day out for years to come. When you demand reliable energy storage count on U.S. Battery every time!
