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.

Cambridge researchers develop standalone device that makes formic acid from sunlight, CO2 and water

Green Car Congress

Researchers at the University of Cambridge, with colleagues at the University of Tokyo, have developed a standalone device that converts sunlight, carbon dioxide and water into formic acid, a carbon-neutral fuel, without requiring any additional components or electricity. —senior author Professor Erwin Reisner.

Exeter team develops low-cost photoelectrode for spontaneous water-splitting using sunlight

Green Car Congress

The nanostructured photoelectrode results in spontaneous hydrogen evolution from water without any external bias applied with a faradaic efficiency of 30% and excellent stability. A promising way of storing solar energy is via chemical fuels, in particular hydrogen as it is considered as a future energy carrier.

Chinese researchers develop new alloy for on-board hydrogen production for fuel cells

Green Car Congress

Researchers from the Chinese Academy of Sciences and Tsinghua University have used a gallium, indium, tin and bismuth alloy to generate hydrogen, when placed in contact with an aluminum plate immersed in water. The hydrogen is then used in a PEM fuel cell. Before use, Al and the LM alloys were stored separately to prevent passivation.

HyMethShip seeks to fuel ship engines with hydrogen from methanol

Green Car Congress

The EU-funded HyMethShip project developed a system that innovatively combined a membrane reactor, a CO 2 capture system, a storage system for CO 2 and methanol as well as a hydrogen-fueled combustion engine to power ships. The remaining carbon dioxide is stored in the tank and reused in onshore methanol production. © Fraunhofer.

Toyota and DIFFER partner on direct solar production of hydrogen from humid air, rather than water

Green Car Congress

The Dutch Institute for Fundamental Energy Research ( DIFFER ) is partnering with Toyota Motor Europe (TME) to develop a device that absorbs water vapor, and splits it into hydrogen and oxygen directly using solar energy. One of these sustainable fuels is hydrogen, which can be used to store renewable energy.
