On January 3, 2025, the U.S. Department of the Treasury and the Internal Revenue Service unveiled the final rules for the Section 45V clean hydrogen production tax credit after much anticipation. The regulations, effective from January 10, 2025, provide clarity on eligibility criteria and compliance requirements for hydrogen producers seeking a credit of up to $3 per kilogram of clean hydrogen. The new rules strike a balance between fostering investment in hydrogen technologies and upholding high environmental standards. They emphasize incrementality, deliverability, and temporal matching to ensure genuine greenhouse gas emissions reductions across the hydrogen supply chain. Noteworthy changes include the inclusion of nuclear power as an eligible source and the allowance of hydrogen production from methane reforming with CCS and natural gas alternatives. The extended transition period and hourly matching requirements post-2030 aim to align hydrogen production with clean energy availability and minimize indirect emissions. These measures, along with broader eligibility for hydrogen sources, seek to encourage innovation and diverse pathways for clean hydrogen production, incorporating various feedstocks. Overall, the sentiment towards the new regulations is positive, with a focus on supporting industry growth while adhering to environmental objectives. The rules provide flexibility for industry transition and lay a foundation for enhanced collaboration between stakeholders and the government in advancing clean hydrogen production in the United States.
