Hydrogen (H2) market demand is forecast to expand. Bulk petrochemicals, ammonia, methanol and gasoline refining consume nearly two-thirds of global H2 demand. These facilities typically have H2 requirements of up to 250,000 Nm3/hr. The remaining H2 demand is directed to process industries including chemicals, pharmaceuticals, metallurgy (steel), glass and semiconductor manufacturing. Four main sources exist for the commercial production of H2: natural gas, oil refining, coal, and electrolysis (Fig. 1). H2 can be produced using diverse domestic resources including nuclear energy, natural gas, coal, biomass and other renewable sources. Fig. 1. Total H2 gener
