The One Big Beautiful Bill Act (OBBBA), enacted on July 4, introduces sweeping changes to U.S. energy policy, significantly altering the tax credit landscape for clean energy projects. The act repeals key provisions of the Inflation Reduction Act, including longstanding renewable energy tax credits, and imposes stricter construction timelines to qualify for remaining incentives (Figure 1).
Despite these rollbacks, the OBBBA preserves tax credit transferability and extends direct pay options for critical credits for CCUS (45Q), green hydrogen (45V) and clean manufacturing (45X). It also overhauls clean fuel (45Z) and hydrogen credits, disadvantaging green hydrogen and sustainable aviation fuel while favoring renewable diesel, biodiesel, ethanol and RNG. Some 65% of planned clean hydrogen projects in the U.S. must accelerate timelines to ensure project competitiveness. These faster construction schedules necessitate developers to prioritize technology like biomass gasification over green hydrogen to preserve access to lucrative tax credits. Producers must integrate technologies and diversify revenue pathways to position themselves for success in an evolving market. The OBBBA delivers a significant setback to the wind and solar sectors by repealing the investment tax credit and production tax credit. Still, our analysis finds that 30% and 57% of the respective L48 queued solar and onshore wind capacity remain economically viable even in the absence of these credits. Taken together, the legislation represents a dramatic reconfiguration of federal energy incentives. Developers face mounting pressure to act swiftly to navigate shifting policies, stricter eligibility rules and tighter construction deadlines.
