However, these sources are variable in nature, which means that there needs to be an investment in energy storage that can last not only hours but days or even seasons. One of the most promising modes of energy storage is the conversion of clean, renewable electricity to hydrogen. Hydrogen is typically generated using green energy through electrolysis, the separation of hydrogen from water within the water, which does not emit any CO2 and is, therefore, “Green H2.”
Green Hydrogen Development
Green H2 development, use, and investment are on the rise globally. The United States Department of Energy highlighted hydrogen’s benefits within the clean energy sector, saying, “Hydrogen can be produced domestically…when used to power highly efficient fuel cell electric vehicles, hydrogen holds the promise of helping strengthen national energy security, conserve fuel, and diversify our transportation energy options for a more resilient system.”
