Three-part catalyst study advances conversion of CO2 to ethanol

Green Car Congress

An international collaboration of scientists has taken a significant step toward the realization of a nearly “green” zero-net-carbon technology that can efficiently convert CO 2 and hydrogen into ethanol. None of the three components examined in the study is able to individually catalyze the CO 2 -to-ethanol conversion, nor can they in pairs.

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. Furthermore, the maximum efficiency of solar energy conversion by photosynthesis is 5%, while typical solar panel efficiency reaches 20%. If these are achieved, carbon yield and productivity can be greatly accelerated (e.g.,

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.

DOE to award up to $30M for direct air and ocean capture of CO2; conversion to fuels and chemicals

Green Car Congress

Projects selected under this funding opportunity announcement (FOA) will perform conceptual design studies followed by field validations of cost-effective processes for ocean-based carbon capture and for direct air capture of CO 2 coupled with carbon-free hydrogen and captured CO 2 to create carbon-neutral methanol.

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. This gives a direct tailpipe CO 2 emission savings based on the comparative use of zero carbon hydrogen instead of diesel. Earlier post.)

Phillips 66 progressing its conversion of California refinery to renewable fuels

Green Car Congress

In April, the company completed the diesel hydrotreater conversion, which will ramp up to 8,000 bbl/d (120 million gallons per year) of renewable diesel production by the third quarter of 2021. Subject to permitting and approvals, full conversion of the refinery is expected in early 2024. Earlier post.).

Researchers develop novel graphene/silicon catalyst for highly selective photoelectroreduction of carbon dioxide to ethanol

Green Car Congress

C 2 H 5 OH was therefore exclusively generated with a selectivity of >99% and a CO 2 conversion rate of 17.1mmol g cat -1 h -1 under simulated solar irradiation with a small bias (-50 mV bias vs. Ag/AgCl) and ambient conditions. The researchers found that CH 3 OH formation was largely suppressed in favor of C-C coupling. Resources Feng, G.,
