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. Water microdroplets are the hydrogen source for N 2 in contact with Fe 3 O 4. The conversion rate reaches 32.9 ± 1.38

U Oregon team advances effectiveness of catalytic water dissociation in bipolar membranes

Green Car Congress

Researchers at the University of Oregon have advanced the effectiveness of the catalytic water dissociation reaction in bipolar membranes. The technology behind bipolar membranes, which are layered ion-exchange polymers sandwiching a water dissociation catalyst layer, emerged in the 1950s. —Oener et al. —Shannon Boettcher.

CICERO-led study finds global warming effect of leaked hydrogen almost 12x stronger than CO2

Green Car Congress

The open-access paper is published in Nature Communications Earth & Environment. Unlike exhaust from burning coal and gas that contains CO 2 , burning hydrogen emits only water vapor and oxygen. We used five different atmospheric chemistry models and investigated changes in atmospheric methane, ozone and stratospheric water vapor.
