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.

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.

Air France KLM signs 210M gallon SAF offtake agreement with DG Fuels

Green Car Congress

The feed-stock reduction is achieved primarily by supplementing the process with oxygen and hydrogen produced by water electrolysis units that are powered by clean wind and solar generated electricity. DGF’s cellulosic feedstock does not impair food supply and is essentially water neutral.

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

The impacts of the various grid scenarios on quantitative life cycle environmental impact, land required, and water use are considered for future market scenarios under the context of the forecast energy requirements for aircraft operations at Chicago O’Hare International Airport. Or is it better to liquefy it on site at the airport?

Eneos opens demo plant in Australia to produce MCH liquid organic hydrogen carrier

Green Car Congress

Eneos’ Direct MCH uses an electrolyzer to produce MCH directly from water. Water is oxidized on the anode catalyst to produce oxygen, protons, and electrons. After dehydrogenation, the toluene can be reused to create MCH again. Both toluene and MCH are toxic substances.
