Both non-renewable energy sources like coal, natural gas, and nuclear power as well as renewable energy sources like hydro, wind, wave, solar, biomass, and geothermal energy can be used to produce hydrogen. The incredible energy storage capacity of hydrogen has been demonstrated by calculations, which reveal that 1 kilogram of hydrogen contains ...
Hydrogen and fuel cells can be incorporated into existing and emerging energy and power systems to avoid curtailment of variable renewable sources, such as wind and solar; enable a more optimal capacity utilization of baseload nuclear, natural gas, and other hydrocarbon-based plants; provide voltage and frequency stabilization support for the electric grid; and/or provide …
The advantage of this strategy is that hydrogen can be stored for longer periods than electricity, allowing energy to be used when needed, such as when renewable energy supply is low or energy demand is high [206, 207]. Microgrids powered by hydrogen can also be utilized as a backup power supply for important infrastructure such as hospitals ...
Liquefied hydrogen can be stored in super-cooled (cryogenic) tanks for transportation applications in fuel cell vehicles or directly as fuel in truck, rail, marine, and rocket engines—NASA has the two largest liquid hydrogen storage tanks in the world.

Hydrogen is an energy carrier, not an energy source and can deliver or store a tremendous amount of energy. Hydrogen can be used in fuel cells to generate electricity, or power and heat. Today, hydrogen is most commonly used in petroleum refining and fertilizer production, while transportation and utilities are emerging markets.
Fuel Storage. Hydrogen''s energy content by volume is low. This makes storing hydrogen a challenge because it requires high pressures, low temperatures, or chemical processes to be stored compactly. Overcoming this challenge is important for light-duty vehicles because they often have limited size and weight capacity for fuel storage.
