Hydrogen is a clean energy carrier that can play an important role in the global energy transition. Its sourcing is critical. Green hydrogen from renewable sources is a near-zero carbon production route. Important synergies exist between accelerated deployment of renewable energy and hydrogen production and use.
Hydrogen is a clean fuel that, when consumed in a fuel cell, produces only water. Hydrogen can be produced from a variety of domestic resources, such as natural gas, nuclear power, biomass, and renewable power like solar and wind. These qualities make it an attractive fuel option for transportation and electricity generation applications.
Combined with the expected drop in the cost of renewable energy, this can bring the cost of renewable-based hydrogen down to a range fo USD 1.3-4.5/kg H 2 (equivalent to USD 39-135/MWh). The lower end of this range is in regions with good access to renewable energy where renewable hydrogen could already be structurally competitive with unabated
