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.

Researchers split seawater without pre-treatment to produce green hydrogen

Green Car Congress

The use of vast amounts of high-purity water for hydrogen production may aggravate the shortage of freshwater resources. This is achieved by introducing a Lewis acid layer (for example, Cr 2 O 3 ) on transition metal oxide catalysts to dynamically split water molecules and capture hydroxyl anions.

DISCOVR project seeking high productivity algae to reduce cost of biofuels

Green Car Congress

Researchers at Pacific Northwest National Laboratory, with colleagues from Los Alamos, Sandia and NREL, are working to lower the cost of producing biofuels from algae. Determining strains of algae that are highly productive could help lower the cost of biofuel production.

These methodologies will significantly decrease the levelized cost of energy (LCOE) of the final HKT design. The proposed RAFT, made up of multiple micro-turbines, has a modularized architecture with reconfigurable units, making it adaptable to different applications and marine environments.

[(PY5Me 2 )Mo(CF 3 SO 3 )] 1+ reacts with water to form. In addition, our catalyst does not require organic additives, and can operate in neutral water, even if it is dirty, and can operate in sea water, the most abundant source of hydrogen on earth and a natural electrolyte.

Artificial enzymatic pathway delivers 1,000-fold enhancement in H2 produced by biological water splitting; more than 1g H2/L/h

Green Car Congress

Researchers from Virginia Tech developed an in vitro artificial enzymatic pathway that can produce hydrogen at extremely high rates by splitting water energized by carbohydrates (e.g., It is highly expected that green, cost-competitive, distributed H 2 will be produced via water splitting powered by solar energy directly or indirectly.
