THREE STEPS TO CLAIM §45V
Determine Lifecycle Emissions
Run the GREET (Greenhouse gases, Regulated Emissions, and Energy use in Technologies) model for your production pathway. The result determines your credit tier.
Satisfy Additionality Requirements
Confirm new-build, temporal matching, and geographic deliverability for the clean electricity source. Annual matching is allowed for electricity generated before 2030; hourly matching is required after that.
Claim Credit Annually (Form 7210)
File Form 7210 for each tax year during the 10-year production window. Credits are transferable and direct-pay eligible for tax-exempt entities.
TIERS BY LIFECYCLE EMISSIONS
The 45V credit rate is determined by a tiered structure based on lifecycle greenhouse gas emissions measured using the GREET model developed by Argonne National Laboratory. Hydrogen with lifecycle emissions above 4.0 kg CO2e/kg does not qualify.
Prevailing wage and apprenticeship requirements apply; non-compliant projects receive 20% of the above rates. Source: 26 U.S.C. §45V, as amended by the One Big Beautiful Bill Act (P.L. 119-21).
TREASURY FINAL RULES (2025)
The Treasury Department's final 45V regulations (T.D. 10023, published January 10, 2025) established additionality, temporal matching, and geographic deliverability requirements for electrolytic hydrogen. These rules ensure that clean hydrogen production genuinely reduces grid emissions.
Annual matching is allowed for electricity generated before January 1, 2030. From 2030, hourly matching is required, which demands more sophisticated energy attribute certificate (EAC) tracking systems. Plan accordingly. Source: 26 CFR §1.45V-4.
ELECTROLYZER VS SMR + CCS
- +Electrolyzer powered by wind or solar
- +Achieves Tier 1 ($3.00/kg) if power is zero-carbon
- +Additionality, temporal, and geographic rules apply
- +45V on electrolyzer; ITC on generation asset
- +GREET model run required annually
- +Natural gas steam methane reforming + carbon capture
- +Tier 3–4 rates ($0.60–$0.75/kg) with 75–90% CCS
- +Higher capture rates unlock better tiers
- +No 45V if carbon capture equipment at the facility earns 45Q (IRC §45V(d)(2)), so choose one
- +Methane leakage rate affects GREET calculation
GREEN HYDROGEN FACILITY
OPTIMAL PROJECT STRUCTURE
The most effective structure for green hydrogen projects separates the generation asset (eligible for ITC) from the electrolysis equipment (eligible for 45V).
Carbon capture is different: no 45V credit is allowed for hydrogen produced at a facility whose carbon capture equipment earns a 45Q credit (IRC §45V(d)(2)). A blue hydrogen project claims one or the other, not both.
