The Clean Hydrogen Production Tax Credit under Section 45V, introduced through the Inflation Reduction Act of 2022, aims to boost low-carbon hydrogen production in the United States as part of the Biden Administration's green energy initiative. The credit offers up to $3 per kilogram of eligible clean hydrogen generated by qualified facilities constructed before 2033 for a decade after commencement of operations. Proposed regulations released in December 2023 by the Treasury Department and IRS triggered significant feedback, particularly concerning the eligibility of hydrogen produced using various electricity sources. Final Regulations issued on January 3, 2025, built upon the Proposed Regulations, adding guidelines for claiming the credit, including provisions for Energy Attribute Certificates and flexibility in meeting emission requirements. These regulations also address the use of methane reformation technologies and renewable natural gas in hydrogen production, providing clarity on GHG emission rates and introducing a 'book-and-claim' system. The Final Regulations are seen as a crucial step towards a cleaner hydrogen economy and signify the US's commitment to green energy transition. They offer clear guidelines for stakeholders in the clean hydrogen sector, enhancing investor confidence and facilitating the growth of sustainable energy practices.
