Researchers from MIT and Sun Catalytix develop an artificial leaf for solar water splitting to produce hydrogen and oxygen

Green Car Congress

Researchers led by MIT professor Daniel Nocera have produced an “artificial leaf”—a solar water-splitting cell producing hydrogen and oxygen that operates in near-neutral pH conditions, both with and without connecting wires. Earlier post.). simulated sunlight. constructing a simple, stand-alone device composed of.

NREL researchers capture excess photon energy to produce solar fuels; higher efficiency water-splitting for H2

Green Car Congress

The advancement could significantly boost the production of hydrogen from sunlight by using the cell to split water at a higher efficiency and lower cost than current photoelectrochemical approaches. Beard and other NREL scientists in 2011 published a paper in Science that. The research is outlined in a paper in Nature Energy.

UC Davis ITS researchers take a detailed look at water consumption and withdrawal requirements for ethanol

Green Car Congress

Water consumption intensity of ethanol from corn grain and crop residue and the avoided/displaced water use credits assigned to coproducts: DGS and electricity. In their paper, Mishra and Yeh analyze the lifecycle water requirement consumption and withdrawal requirements of ethanol produced from corn and from crop residue.

Hydrogenics wins order from E.ON for power-to-hydrogen-gas energy storage project in Germany

Green Car Congress

Power-to-Gas is a novel way to store energy at utility scale, whereby surplus electrical grid power is converted into hydrogen gas. The electrolysis of water into hydrogen whenever surplus electrical power is available is the optimal pathway to increase the renewable content in the energy system mix.

US Foodservice acquires WVO company to reduce environmental impact of its fleet

Green Car Congress

WVO collects and removes water, food particles and other impurities from waste vegetable oil then ships the bio feedstock to a processing company that produces an 80/20 diesel/biodiesel blend (B20) that will be used to fuel hundreds of food delivery trucks at the US Foodservice-Columbia Division in Lexington, SC.

CO2-neutral hydrogen storage with a bicarbonate/formate system

Green Car Congress

Metal hydride tanks store hydrogen in a relatively manageable volume but are very heavy and expensive, as well as operating only at high temperatures or far too slowly. The nontoxic aqueous solution of formate is easily stored and transported. to sodium formate in 96% yield at 70 °C in water/THF without additional CO 2.
