Hydrogen energy refers to the use of hydrogen as a clean and versatile energy carrier which is capable of storing, moving and delivering energy produced from diverse sources such as water, fossil fuels or biomass to power vehicles, generate electricity and heat buildings.
Hydrogen - Department of Energy
Hydrogen has been described as the “Swiss army knife” of energy because it plays a key role in several sectors where there are limited or no viable alternatives (including in applications where electrification is particularly challenging or costly).
What it would take to unlock the next phase of hydrogen ...
Low-emissions hydrogen production – or the production of hydrogen from low-emissions electricity via water electrolysis, from bioenergy or from fossil fuels in combination with carbon capture and storage – is still at an early stage today.
