Shares of Constellation Energy and other nuclear-power-focused companies surged following the Biden administration's relaxation of tax-credit regulations for hydrogen production. The Treasury Department and IRS finalized rules under the Inflation Reduction Act, expanding tax credits to promote renewable energy, particularly clean-hydrogen production. This development enables some nuclear power plants facing retirement risks to engage in hydrogen production using fuel cells. John Podesta, senior climate advisor to President Biden, praised the revisions, emphasizing the importance of providing certainty to hydrogen producers to propel projects forward and establish the U.S. as a leader in 'truly green hydrogen.' The move is expected to incentivize investment in clean hydrogen, which had faced uncertainty. The stock market responded positively, with Constellation Energy and other companies like Vistra and NextEra Energy experiencing notable gains. Constellation's CEO, Joe Dominguez, welcomed the new rules, highlighting the potential for significant portions of the existing nuclear fleet to earn credits for hydrogen production. Analysts foresee the new regulations spurring investment in clean hydrogen and benefiting companies like Constellation, Public Service Enterprise Group, and Vistra in the long term. The positive momentum was reinforced by Constellation's recent contract win to supply nuclear energy to 13 government agencies. Overall, the Biden administration's tax-credit boost for nuclear power and hydrogen production has ignited optimism in the energy sector, positioning the U.S. for enhanced global competitiveness in green hydrogen innovation.
