EPFL team develops low-cost water splitting cell with solar-to-hydrogen efficiency of 12.3%

Green Car Congress

Michael Grätzel at EPFL (Ecole Polytechnique Fédérale de Lausanne) in Switzerland has developed a highly efficient and low-cost water-splitting cell combining an advanced perovskite tandem solar cell and a bi-functional Earth-abundant catalyst. conversion efficiency from solar energy to hydrogen, a record with earth-abundant materials.

ASU and Argonne researchers report progress on artificial leaf for solar conversion of water to H2 and O2

Green Car Congress

Designing an artificial leaf that uses solar energy to convert water cheaply and efficiently into hydrogen and oxygen is one of the goals of BISfuel (Bio-inspired Solar fuel production)—the Energy Frontier Research Center, funded by the Department of Energy, in the Department of Chemistry and Biochemistry at Arizona State University.

USDA provides $91M loan guarantee to Cool Planet for biogasoline blendstock plant; biomass pyrolysis and catalytic conversion

Green Car Congress

Cool Planet has devised a biomass-to-liquids thermochemical conversion process that simultaneously produces liquid fuels and sequesterable biochar useful as a soil amendment. The output from each catalytic array when cooled is comprised of volatile gases, renewable fuel and water. Earlier post.). Depending on the temperature (300 ?C

Researchers develop free-standing nanowire mesh for direct solar water-splitting to produce H2; new design for “artificial leaf”

Green Car Congress

The mesh with BiVO 4 nanowire photoanode for water oxidation and Rh-SrTiO 3 nanowire photocathode for water reduction produces hydrogen gas without an electron mediator. When immersed in water with visible light irradiation (? ? In the present study, we developed a new architecture for direct solar water-splitting.

New one-pot process for conversion of cellulose to n-hexane, a gasoline component

Green Car Congress

One-pot process for conversion of cellulose to hexane, a gasoline component. Even using a high weight ratio of cellulose to water (1:1), a 71% yield of n-hexane could be obtained from ball-milled cellulose. To the best of our knowledge, this conversion process has not yet been reported. Credit: ACS, Liu et al. Click to enlarge.

Joule expands solar CO2 conversion platform to produce renewable gasoline and jet hydrocarbons

Green Car Congress

Joule, the developer of a direct, single-step, continuous process for the production of solar hydrocarbon fuels ( earlier post ), has extended its solar CO 2 conversion platform to produce renewable gasoline- and jet fuel-range hydrocarbons. Joule is now commercializing its first product, Sunflow-E, for global availability in early 2015.
