The final rules for the Clean Hydrogen Tax Credit, established by the Inflation Reduction Act, have been released by the U.S. Department of the Treasury. The rules include significant changes aimed at fostering growth in the clean hydrogen industry and advancing projects while providing clarity and investment certainty. Producers of hydrogen, utilizing sources like electricity, natural gas with carbon capture, renewable natural gas (RNG), and coal mine methane, can now determine eligibility for the section 45V Clean Hydrogen Production Tax Credit. The regulations aim to drive significant deployment of clean hydrogen to power heavy industry and create employment opportunities. They incorporate feedback from companies planning investments and support the Biden administration's ambitious policy to bolster the clean hydrogen industry. The rules enable pathways for clean hydrogen production using different sources while ensuring compliance with emissions standards. They focus on decarbonizing various sectors, enhancing accuracy in methane leakage rates, and providing investment certainty for producers. Additionally, the regulations enhance the development of book-and-claim systems for natural gas alternatives and offer flexibility by allowing the use of a specific model for the credit period to ensure investment stability.
