Clarity for Investment: The Inflation Reduction Act’s final rules resolve important concerns and provide assurance for clean hydrogen projects.

Lifecycle Emissions Standards: Provides stringent greenhouse gas (GHG) requirements for hydrogen that meets them, with credit levels determined by the intensity of emissions.

Incorporated Industry Feedback: Stakeholder input is reflected in the rules, which simplify the process of producing clean hydrogen.

The U.S. Department of the Treasury and the IRS have issued final rules for the Section 45V Clean Hydrogen Production Tax Credit, designed to boost industry growth while enforcing strict emissions standards. These regulations define eligibility for producers utilizing electricity, natural gas with carbon capture, renewable natural gas (RNG), and coal mine methane.

Key Provisions:

Lifecycle Emissions Threshold:

• Clean hydrogen must emit no more than 4 kg of CO₂e per kilogram of hydrogen produced.

• Credit levels are tiered, with lower emissions earning higher incentives.

• Both direct and significant indirect emissions are factored into eligibility.

Electrolytic Hydrogen (Green and Pink Hydrogen):

• Safeguards ensure compliance with emissions standards, including:

  • Incrementality: Hydrogen producers must use electricity from new or expanded clean power sources operational within 36 months.

  • State Policies: Electricity from states with robust GHG caps (e.g., California, Washington) qualifies as incremental.

  • Hourly Matching: By 2030, producers must match renewable electricity generation with grid demand on an hourly basis.

Methane-Based Hydrogen (Blue Hydrogen):

• Credit calculations incorporate national and project-specific methane leakage rates.

• Expands eligibility to biogas sources, such as wastewater and landfill gas.

• Supports the development of “book-and-claim” systems for RNG by 2027.

Industry Alignment:

The Treasury Department considered 30,000 public comments and collaborated with the Department of Energy and EPA to finalize the rules. Updated tools, including the forthcoming 45VH2-GREET model, will enable accurate emissions tracking and compliance assurance.

These measures aim to drive investment, simplify regulatory processes, and position the U.S. as a global leader in clean hydrogen innovation.
