Photoelectrochemical water-splitting for solar hydrogen production

Renewable energy research

A technology that directly converts sunlight into hydrogen fuel by splitting water molecules using solar energy. Developed by NREL over more than a decade, it has advanced considerably since its initial use in 1998.

Technology that generates electricity through an electrochemical reaction between hydrogen and oxygen, with water as the only byproduct.
