On January 3, 2025, the U.S. Department of the Treasury and the IRS revealed the final rules for the Section 45V clean hydrogen production tax credit, effective January 10, 2025. These rules clarify criteria and compliance for hydrogen producers to claim a credit of up to $3 per kilogram of clean hydrogen. The regulations balance environmental standards and industry needs, focusing on incrementality, deliverability, and temporal matching to encourage clean hydrogen production. The regulations emphasize, among others, incrementality requiring electricity from non-traditional sources, deliverability ensuring physically deliverable electricity, and temporal matching aligning hydrogen production with clean energy availability. The rules broaden eligibility, allowing methane reforming with CCS, natural gas alternatives, and providing flexibility for industry transitions. Incorporating stakeholder feedback, the rules introduce measures like additional CCS pathways, grid integration, and life cycle emissions adjustments. These changes support innovation and diverse clean hydrogen pathways while supporting industry growth and environmental goals. The regulations aim to bolster investment in emerging hydrogen technologies while maintaining high environmental standards.
