The Biden administration has unveiled final rules for a tax credit aimed at boosting cleaner hydrogen production, with a focus on displacing fossil fuels in sectors like long-haul transportation and industrial manufacturing. While most hydrogen is currently produced from natural gas, the new rules extend the credit to firms using technology that captures emissions, as well as those producing hydrogen from alternative sources like wastewater and animal manure. The credit, part of the Democrats' Inflation Reduction Act, has bipartisan support and aims to reduce planet-warming emissions by promoting the production of clean hydrogen. Environmental groups have praised the rules for supporting clean hydrogen projects that do not worsen climate and health-harming pollution, but express concerns that producers of dirty hydrogen could also benefit. Industry experts see the tax credit as a significant step towards decarbonizing hard-to-electrify sectors, such as aviation and steel production, by incentivizing the use of clean hydrogen. Although there are worries about accurately tracking emissions from natural gas-produced hydrogen, the overall sentiment is positive, with hopes that the tax credit will drive investment and industry confidence in cleaner hydrogen production.
