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

Researchers develop highly efficient organometal halide perovskite photoelectrodes for water splitting

Green Car Congress

Photoelectrochemical (PEC) water splitting based on solar energy is one promising approach for the production of green hydrogen. However, its widespread application is limited by a lack of efficient photoanodes for catalyzing the rate-limiting oxygen evolution reaction (OER), an important reaction in PEC water splitting.

Study finds direct seawater splitting has substantial drawbacks to conventional water splitting, offers almost no advantage

Green Car Congress

A study by a team of researchers from Technische Universität Berlin (TUB) and Fritz-Haber-Institut der Max-Planck-Gesellschaft has found that direct seawater splitting for hydrogen production has substantial drawbacks compared to conventional water splitting and offers almost no advantage. Additionally, H 2 O is needed for water splitting.

Pitt engineers using membrane distillation to recycle water used in fracking and drilling

Green Car Congress

Engineers at the University of Pittsburgh Swanson School of Engineering are using membrane distillation technology to enable drillers to filter and reuse the produced water in the oil and gas industry, in agriculture, and other beneficial uses. The method is already being tested in Texas, North Dakota, and most recently in New Stanton, Pa.
