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.

MITEI study finds hydrogen-generated electricity is a cost-competitive candidate for backing up wind and solar

Green Car Congress

A team at MITEI (MIT Energy Initiative) has found that hydrogen-generated electricity can be a cost-competitive option for backing up wind and solar. California draws more than 20% of its electricity from solar and approximately 7% from wind, with more VRE coming online rapidly. —Drake Hernandez. 2021.117314.

U of Melbourne team demonstrates direct hydrogen production from air; direct air electrolysis (DAE)

Green Car Congress

Researchers at the University of Melbourne (Australia) have demonstrated a method of direct hydrogen production from air— in situ capture of freshwater from the atmosphere using hygroscopic electrolyte and subsequent electrolysis powered by solar or wind with a current density up to 574 mA cm ?2.

Study finds GWP of electrolyzed hydrogen to meet ORD’s fuel needs would be 2.5x that of fossil fuels with 2020 grid mix

Green Car Congress

If only incremental increases in renewable energy resources are introduced across the grid, electrolytic hydrogen will not become an environmentally sustainable solution. Hydrogen is very attractive because it only produces water vapor emissions when utilized on an aircraft. Ansell presented his findings at AIAA Aviation 2023 in June.

ANL: life-cycle water consumption of fuel cell vehicles can be cut in half compared to that of conventional ICE vehicles

Green Car Congress

The life-cycle water consumption of fuel cell electric vehicles using hydrogen produced from natural gas with steam methane reforming is almost 50% less than the life-cycle water consumption of conventional internal combustion engine vehicles using gasoline, according to a study by researchers at Argonne National Laboratory (ANL).

DLR team integrates solar heat into solid oxide electrolyzer for highly efficient hydrogen production

Green Car Congress

A team at Deutsches Zentrum für Luft- und Raumfahrt (DLR) has successfully integrated solar heat into a solid oxide electrolyzer. The experimental setup of the prototype system consisted of a solar simulator, a solar steam generator, a steam accumulator and a solid oxide electrolyzer. Schiller et al. A small fraction (0.58

Sinopec Xinjiang Kuqa green hydrogen pilot project enters operation

Green Car Congress

As China’s first green hydrogen demonstration project of over 10,000-tonne capacity and based on solar power, it is expected to produce 20,000 tonnes of green hydrogen per year that will be supplied to Sinopec’s Tahe refinery. Sinopec’s Xinjiang Kuqa Green Hydrogen Pilot project enters operation, leading China’s green hydrogen development.
