Two major pieces of early-2020s legislation — the Bipartisan Infrastructure Law (2021) and the Inflation Reduction Act (IRA; 2022) — promise to provide billions of dollars in tax credits and other incentives for expanding the production of low-carbon-intensity (LCI) hydrogen. But the hype around clean hydrogen as a fuel of the future has lost some momentum of late, mostly due to spiraling costs. So we’re left with two questions: Can expanded production and use of LCI hydrogen significantly reduce carbon dioxide (CO2) emissions and, just as important, is LCI hydrogen production cost-effective?
