Stanford engineers develop catalyst strategy to improve turnover frequencies for CO2 conversion to hydrocarbons by orders of magnitude

Green Car Congress

Researchers at Stanford University have shown that porous polymer encapsulation of metal-supported catalysts can drive the selectivity of CO 2 conversion to hydrocarbons. To capture as much carbon as possible, you want the longest chain hydrocarbons. Chains with eight to 12 carbon atoms would be the ideal. —Zhou et al.

UCLA team proposes non-photosynthetic biological conversion of CO2

Green Car Congress

Most of us naturally associate biological CO 2 conversion with photosynthesis in plants and algae. While engineering photosynthetic hosts to convert CO 2 into high-value products is sensible, dependence on sunlight limits its tractability and scalability. Their paper is published in the journal Joule. each gram of acetogenic M.

BMW i Ventures invests in Prometheus Fuels; CO2 air-capture and conversion to carbon-neutral gasoline

Green Car Congress

BMW i Ventures has invested in Prometheus Fuels ( earlier post ), a company removing CO 2 from the air and turning it into zero-net carbon gasoline that it will sell at gas stations, at a price that competes with fossil fuels, starting as early as this year. —Greg Smithies, Partner, BMW i Ventures. to C 2 fuel products such as ethanol.

Aberdeen awards ULEMCo contract for 35 hydrogen dual-fuel utility vehicle conversions

Green Car Congress

ULEMCo has been awarded a major fleet-wide contract by Aberdeen City Council (ACC) for its hydrogen dual-fuel utility vehicle conversions. ULEMCo’s H2ICED allows hydrogen to be mixed with diesel directly in a conventional engine, supplied via onboard gas tanks, in volumes that displace between 30-70% of the energy from diesel.
