Four U.S. Nuclear Plants to Start Producing Hydrogen

The U.S. Department of Energy (DOE) is partnering with utilities on four hydrogen demonstration projects at U.S. nuclear power plants.

Hydrogen would be produced at the nuclear plants through high- or low-temperature electrolysis, a process of splitting water into pure hydrogen and oxygen. High-temperature electrolyzers use both heat and electricity to split water and are more efficient.

Many believe nuclear is a tool to produce clean hydrogen, which is seen as an important path to drive decarbonization – including in hard-to-abate sectors. In power generation, hydrogen is one of the leading options for storing renewable energy and can be used in gas turbines to increase power system flexibility.
