The US Department of the Treasury has unveiled the final rules for hydrogen production credits under the Inflation Reduction Act of 2022, offering a tax credit for hydrogen production that meets specific greenhouse gas emission criteria. The rules aim to promote clean hydrogen production across the supply chain by rewarding low-carbon electrolysis and methane splitting methods. Environmental groups and industry stakeholders have responded differently to the regulations, with some praising the policy improvements while others express concerns about certain provisions. The rules include requirements for hourly matching of electricity generation with hydrogen production and ensuring new hydrogen capacity matches new low-carbon energy sources. Additionally, nuclear power plants are acknowledged as clean energy sources for hydrogen production, with incentives for reducing methane emissions in fossil-based clean hydrogen projects. The regulations also mandate the use of the GREET lifecycle analysis model to calculate the carbon footprints of hydrogen plants and determine tax credits. The policy framework aims to provide certainty to project developers and investors while encouraging technological advancements in clean hydrogen production.
