World's first "aqueous solar flow battery" outperforms traditional lithium-iodine batteries

The scientists that revealed the "world's first solar battery" last year are now, following some modifications, reporting its first significant performance milestone. The device essentially fits a battery and solar cell into the one package, and has now been tested against traditional lithium-iodine batteries, over which the researchers are claiming energy savings of 20 percent.Read More

Battery juices itself up using light

It's now fairly common to hear about batteries being used to store power generated by solar cells. A group of Indian scientists, however, have eliminated the middleman. They've created a battery that incorporates a titanium nitride-based photoanode in place of a conventional anode, allowing the battery to charge itself using solar or artificial light.Read More

Miniature car runs only on the power of evaporating water

Researchers have discovered an unlikely source of renewable energy, the naturally-occurring cycle that is water evaporation. Scientists at New York's Columbia University replicated this process in the laboratory and harnessed its energy to power tiny machines, one of which was a moving, miniature car. The team says the technology could potentially to be scaled up to one day draw power from huge resting bodies of water such as bays and reservoirs. Read More

Study shows how the US could achieve 100 percent renewable energy by 2050

A team of researchers led by Stanford University's professor Mark Z. Jacobson has produced an ambitious roadmap for converting the energy infrastructure of the US to run entirely on renewable energy in just 35 years. The study focuses on the wide-scale implementation of existing technologies such as wind, solar and geothermal solutions, claiming that the transition is both economically and technically possible within the given timeframe.

Daimler to offer Mercedes-Benz energy-storage system

Tesla recently did it to much acclaim, and now Daimler is doing it too – the German automotive corporation is launching its own home/business battery energy storage system. Developed by Daimler subsidiary Deutsche ACCUmotive, the Mercedes-Benz energy storage unit utilizes lithium-ion batteries to store energy generated by solar cells, wind turbines or other sources.Read More

New heat-recovery system makes Stanford one of world’s most energy-efficient uni's

At Stanford University in California, it’s normally the Nobel-winning researchers who make the news. But with the commissioning of a novel renewable energy system, the campus’s humble heating and cooling system has grabbed some headlines. Using a first-of-its-kind heat recovery system, and drawing a substantial percentage of its electricity from solar, the university is greening up its operations in a move that will see greenhouse gas emissions cut by 68 percent and fossil fuel use cut by 65 percent.

Electric cars to become mini power plants in California’s energy grid

The California utility, San Diego Gas & Electric (SDG&E), has begun bidding energy resources from fleets of electric vehicles and storage systems into the state’s wholesale power market. The pilot program, one of the first of its kind, is meant to provide insights into how electric vehicles and other kinds of distributed energy resources can make the grid more reliable and efficient.Read More

Modular biobattery plant turns a wide range of biomass into energy

Researchers at the Fraunhofer Institute have developed a "biobattery" in the form of a highly efficient biogas plant that can turn raw materials like straw, scrap wood and sludge into a variety of useful energy sources including electricity, purified gas and engine oil. The new plant design, currently being put to the test in a prototype plant in Germany, is said to be highly modular and economically viable even at the small scale.Read More
