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.

Lux Research: cost of electrofuels remains far from viable

Green Car Congress

Production costs per barrel of oil equivalent. The cost of electrofuels—fuels produced by catalyst-based systems for light capture, water electrolysis, and catalytic conversion of carbon dioxide and hydrogen to liquid fuels—remains far away from viable, according to a new analysis by Lux Research.

UCSC team develops high-performance nanostructured composite catalyst for water-splitting to produce hydrogen

Green Car Congress

A low-cost, nanostructured composite material developed by researchers at UC Santa Cruz has shown performance comparable to Pt/C as a catalyst for the electrochemical splitting of water to produce hydrogen. An efficient, low-cost catalyst is essential for realizing the promise of hydrogen as a clean, environmentally friendly fuel.

Sandia team boosts hydrogen production activity by molybdenum disulfide four-fold; low-cost catalyst for solar-driven water splitting

Green Car Congress

A team led by researchers from Sandia National Laboratories has shown that molybdenum disulfide (MoS 2 ), exfoliated with lithiation intercalation to change its physical structure, performs as well as the best state-of-the-art catalysts for the hydrogen evolution reaction (HER) but at a significantly lower cost. —Bryan Kaehr.

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

Green Car Congress

To produce cost-effective green hydrogen, industry and energy companies need efficient electrolyzers on a large scale. In addition, AEM technology is characterized by its cheap and non-critical materials—similar to AEL technology.

Researchers from MIT and Sun Catalytix develop an artificial leaf for solar water splitting to produce hydrogen and oxygen

Green Car Congress

Researchers led by MIT professor Daniel Nocera have produced an “artificial leaf”—a solar water-splitting cell producing hydrogen and oxygen that operates in near-neutral pH conditions, both with and without connecting wires. aligned with the low-cost systems engineering and.
