On January 3, 2025, the US Department of the Treasury and the IRS released the Final Rules for the Section 45V Clean Hydrogen Production Tax Credit. These regulations, stemming from the Inflation Reduction Act of 2022, follow a period of public feedback since the Proposed Rules were published a year earlier. With significant modifications, including changes to the Energy Attribute Certificate framework, the Final Rules aim to balance industry concerns and emission standards. Notable adjustments involve criteria for incrementality, flexibility in uprate rules, and the inclusion of various pathways like nuclear reactors and carbon capture technology to qualify for the tax credit. The regulations also maintain requirements for temporal matching of electricity use for hydrogen production. Despite efforts by the Biden Administration to enhance clean hydrogen production incentives, the future outlook is uncertain with the transition to a new administration and Congress. This uncertainty poses challenges for DOE spending, the Section 45V tax credit, and the broader clean energy landscape.
