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. —Song et al. Song et al.

A New Energy-Efficient Hydrogel Pulls Water From Air

Cars That Think

Using a new kind of hydrogel material, researchers at the University of Texas at Austin have pulled water out of thin air at temperatures low enough to be achieved with sunlight. Atmospheric water harvesting draws water from humidity in the air. The UT Austin technique is aimed at the latter.

EU project HyFlexFuel converted sewage sludge and other biomasses into kerosene by hydrothermal liquefaction (HTL); SAF

Green Car Congress

The EU-funded research project HyFlexFuel recently successfully produced biocrudes via hydrothermal liquefaction (HTL) from a variety of biomasses, including sewage sludge, food waste, manure, wheat straw, corn stover, pine sawdust, miscanthus and microalgae in a pilot-scale continuous HTL plant at Aarhus University (Denmark).

Sunfire, Fraunhofer, partners launch project to scale alkaline AEM electrolysis

Green Car Congress

Technologies such as pressurized alkaline or high-temperature electrolysis are already being installed in industrial environments. However, commercially available membranes lack sufficient stability in alkaline environments, which have limited the widespread adoption of AEM in electrolysis applications.

TU Dresden chemists develop noble metal aerogels for electrochemical hydrogen production

Green Car Congress

New-type noble metal aerogels were developed for outstanding pH-universal electrocatalysis toward hydrogen evolution reaction and oxygen reduction reaction. Universal HER and ORR Electrocatalysis.” These findings largely span the application territory of NMAs for fuel cells, green hydrogen production and many more. Credit: Wiley-VCH.
