But hydrogen has its share of skeptics.
Green (or clean) hydrogen represents only 5% of the hydrogen produced in the U.S., due to its high cost, while the remaining 95% is produced using fossil fuels. So-called "blue hydrogen" produced from natural gas incorporates carbon capture and storage, though recent studies suggest the practice could produce even more carbon emissions in heat generation than using natural gas alone.
Last month, dozens of climate groups urged leaders in Congress to avoid funding hydrogen-based technologies in the infrastructure and budget reconciliation packages.
Nevertheless, the Biden administration remains committed to the research and deployment of green hydrogen to address hard-to-decarbonize sectors.
