Researchers demonstrate new nickel selenide catalyst for more efficient water splitting

Green Car Congress

The bifunctional electrocatalyst enables water electrolysis in alkaline solutions at a cell voltage of 1.54 V. Most methods for producing hydrogen and oxygen from water require large amounts of energy and are cost-prohibitive. In addition, this molecular complex exhibits an exceptionally high mass activity (111.02 A g

Stanford team sets record for solar-to-hydrogen efficiency of solar water splitting: >30%

Green Car Congress

Researchers at Stanford University have demonstrated solar water splitting by photovoltaic-electrolysis with a solar-to-hydrogen (STH) efficiency of more than 30%—a new record. However, the cost of H 2 produced by electrolysis is still significantly higher than that produced by fossil fuels. … The prior record was 24.4%.

Researchers demonstrate electrochemical synthesis of ammonia from air and water under mild conditions

Green Car Congress

In industry, extensive purification of N 2 and H 2 is needed and this remarkably increases the overall cost of the process. is well known that some higher plants can synthesize ammonia or its derivatives directly from air and water at room temperature.

Stanford team develops new low-voltage single-catalyst water splitter for hydrogen production

Green Car Congress

Researchers at Stanford University have developed a new low-voltage, single-catalyst water splitter that continuously generates hydrogen and oxygen. In the reported study, the new catalyst achieved 10 mA cm −2 water-splitting current at only 1.51 V V to reach 10 mA cm −2 current (for integrated solar water splitting).

ORNL team discovers mechanism behind direct ethanol-to-hydrocarbon conversion; implications for energy efficiency and cost of upgrading

Green Car Congress

The research, supported by DOE’s BioEnergy Technologies Office (BETO), has implications for the energy efficiency and cost of catalytic upgrading technologies proposed for use in bio-refineries. All these catalysts are robust to water content in ethanol (5–95%) and volatile impurities in fermentation stream. Buchanan & Brian H.
