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. The effective upgrading of alcohols to gasoline, diesel, and jet fuels.

Study finds GHG emissions from corn ethanol now 46% lower than gasoline

Green Car Congress

A new study by a team from Environmental Health & Engineering (EH&E) has found that greenhouse gas emissions from corn ethanol are 46% lower than those from gasoline—a decrease in emissions from the estimated 39% done by previous modeling. gCO 2 e/MJ) which is 46% lower than the average carbon intensity for neat gasoline.

Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

Major ridesourcing companies Uber and Lyft have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. Lead author Aniruddh Mohan and colleagues wanted to develop a method that evaluated the life-cycle costs and benefits for two battery-powered ridesource fleets and a gasoline-powered one.

WSU, GTI system uses electrochemical reforming of ethanol for compressed hydrogen production; CAPER

Green Car Congress

A team from Washington State University (WSU) and the Gas Technology Institute have used an ethanol and water mixture and a small amount of electricity in an electrochemical conversion system to produce pure compressed hydrogen. Without using a membrane, the only gas-phase species is H2. —Kee et al.

ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. If CNG were to be eventually used in hybrids, the advantage of the electric generation/EV option shrinks. Their open access paper is published in the journal Energy.

Haldor Topsoe to build large-scale SOEC electrolyzer manufacturing facility to meet customer needs for green hydrogen

Green Car Congress

Solid oxide electrolysis cell (SOEC) technology is attractive because of unrivaled conversion efficiencies—a result of favorable thermodynamics and kinetics at higher operating temperatures. The SOEC is a ceramic cell that uses electricity to split water molecules (H 2 O) into hydrogen (H 2 ) and oxygen (O 2 ). —Hauch et al.
