US grants $750 million for hydrogen projects across 24 states

The U.S. Department of Energy said on Wednesday it is granting $750 million to projects across 24 states that are building capacity to produce and use clean hydrogen.

Hydrogen is a fuel that the administration of President Joe Biden sees as crucial to reducing use of fossil fuels and cutting emissions from hard-to decarbonize industries such as aluminum and cement.

It is made by electrolyzers that split water into hydrogen and oxygen and can be considered green if they are powered by zero-emission sources like solar, wind, nuclear or hydro.

Today the vast majority of hydrogen is produced through steam methane reforming with unabated emissions, at a fraction of the cost of clean hydrogen.
