Hydrogen offers potential pathways for decarbonizing the electricity system, hard-to-electrify industrial and heating applications, and heavy transportation. There are economic development opportunities for new technologies, processes, and applications as well as opportunities to leverage and adapt some existing natural gas, petroleum, and petrochemical infrastructure and expertise for hydrogen-based energy and production. Research, development, and demonstration (RD&D), environmental policies, economies of scale and scope, economic development programs, and other measures will affect hydrogen’s path. NASEO provides State Energy Offices with information on hydrogen opportunities; potential policy, program, and regulatory options as states develop state energy, environmental, and economic development plans.
