As the planet moves away from carbon based fossil fuels, hydrogen has become one of the most promising advanced fuels for the future, due to its high amount of stored energy per unit weight and the absence of carbon. Hydrogen atoms are found commonly in nature but not as hydrogen molecules. Clean ways to make and use Hydrogen for power generation will be critical to replace conventional methods of power production that use petroleum-based products.

The industry prevailing understanding is that hydrogen is essential to meet global decarbonization goals by 2025 across industries. The International Renewable Energy Agency (IRENA) estimates that by 2050, clean hydrogen could meet 12 percent of energy consumption, and could abate seven gigatons of CO2 emissions annually. If these projections are true, both hydrogen production and hydrogen power plants are necessary to produce green renewable electricity while still maintaining a reliable grid.
