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 create salts for cheap and efficient CO2 capture; mimicking methane hydrate

Green Car Congress

This process worked well; however, the chemical bonds require energy to break them down, which drives up the cost of the CO 2 capture operation. A) CO 2 hydrate where CO 2 molecules are trapped in water clusters at high pressures and low temperatures. (B) Xiang et al.

DOE awards $2.7M to U Florida, Synhelion to support production of hydrogen from concentrated solar

Green Car Congress

The project aims to enable large-scale production of green hydrogen from solar energy by leveraging concentrating solar power (CSP) infrastructure and solar heat to split water (H 2 O) into hydrogen (H 2 ) and oxygen (O 2 ). The production costs of green hydrogen remain a major barrier to wide-scale adoption in the transportation sector.

SoCalGas, H2U testing new Gramme 50 electroylzer for green hydrogen production

Green Car Congress

According to early analysis, the cost target of the new technology is half that of current electrolyzers and the total cost of ownership over its life is expected to be 75% less. Green hydrogen offers the ability to store renewable electricity across months and seasons, an advantage over battery storage.

Stanford team sets record for solar-to-hydrogen efficiency of solar water splitting: >30%

Green Car Congress

Researchers at Stanford University have demonstrated solar water splitting by photovoltaic-electrolysis with a solar-to-hydrogen (STH) efficiency of more than 30%—a new record. However, the cost of H 2 produced by electrolysis is still significantly higher than that produced by fossil fuels. … The prior record was 24.4%.
