The U.S. Treasury has announced final rules for hydrogen producers to qualify for tax credits under the Inflation Reduction Act, ending a long wait for startups in the sector. These regulations aim to ensure that new hydrogen production does not increase greenhouse gas emissions. Producers can earn up to $3 per kilogram for lower-emission hydrogen types. The updated guidelines also permit existing nuclear power plants to contribute electricity, benefiting the industry. Experts express gratitude for the clarity but seek additional flexibility in power sourcing requirements.
