New catalysts convert ethanol to butanol with high selectivity; potential low-cost upgrade for ethanol plants

Green Car Congress

Researchers at the University of Bristol (UK) have developed a new family of catalysts that enables the conversion of ethanol into n-butanol—a higher alcohol with better characteristics for transportation applications than ethanol—with selectivity of more than 95% at good conversion. —Professor Duncan Wass.

volts (V) of water-splitting voltage with its novel low-cost electrolysis technology. Further, overcoming the corrosive degradation of these “artificial photosynthesis” systems remains a challenge and has thus far eluded commercialization. HyperSolar, Inc. announced that it had reached 1.25 V (at 25 °C at pH 0).

Stanford researchers make ammonia from air and water microdroplets

Green Car Congress

Stanford researchers, with a colleague from King Fahd University of Petroleum and Minerals, have developed a simple and environmentally sound way to make ammonia with tiny droplets of water and nitrogen from the air. An open-access paper on their work is published in Proceedings of the National Academy of Sciences (PNAS). —Song et al.

Convert Oil Wells to Solve the Solar Storage Problem

Cars That Think

The California-based Hyperlight Energy will be piloting an installation where they plan to use existing oil wells as solar thermal wellsprings, with the stored energy being converted back to clean electricity when required. Thermal energy storage is a known low-cost, low-risk approach for storing solar energy in the form of heat,” adds Codd.
