But to achieve even a small fraction of this level of hydrogen technology deployment, increased support for research and development will be crucial. The extent to which hydrogen prevents GHG emissions depends on how that hydrogen is made. However, hydrogen production remains dominated by reforming natural gas (95% natural gas, 5% electrolysis). Energy InnovationIn the HD scenario, U.S. hydrogen supply becomes a $130 billion per year industry by 2050 (Fig 2). Energy expenditures remain low, due to the low cost of natural gas and relatively high efficiency of transforming natural gas into hydrogen.
