Sunlight can be used to produce green hydrogen directly from water in photoelectrochemical (PEC) cells. So far, most systems based on this 'direct approach' have not been energetically competitive.

Japanese researchers are closing in on a long promised energy dream, using only sunlight and water to generate clean hydrogen fuel with no smokestacks or power cables in sight. Their latest technology ...

University of Michigan researchers developed a new photocatalytic water splitting system that is reportedly able to reach a 9.2% solar-to-hydrogen (STH) efficiency. The proposed system uses the higher ...

A research team from two London universities have developed a multi-layer device that addresses the instability of organic materials in water to further their use in direct solar hydrogen generation.

Hydrogen can be produced by electrolysis of water, ideally with solar cells or wind power providing the electrical energy required. This "green" hydrogen is expected to play an important role in the ...
