Electrolysis is the process of using electricity to split water into hydrogen and oxygen. The reaction takes place in a unit called an electrolyzer.

In PEC water splitting, hydrogen is produced from water using sunlight and specialized semiconductors called photoelectrochemical materials.

Natural gas reforming is an advanced and mature production process that builds upon the existing natural gas pipeline delivery infrastructure.

Thermochemical water splitting uses high temperatures—from concentrated solar power or from the waste heat of nuclear power reactions—and chemical reactions to produce hydrogen and oxygen from water.

Hydrogen can be produced from diverse, domestic resources including natural gas and other fossil fuels, solar, wind, biomass, and electricity.
