The US Treasury has released final rules on clean hydrogen production, providing clarity on the clean hydrogen production tax credit of up to $3 per kilogram. This has led to increased interest from nuclear energy stocks and companies. Credits for hydrogen production are now available to nuclear power and natural gas producers, potentially unlocking substantial funding. The tax credit, ranging from $0.60 to $3/kg based on carbon emissions, is part of the Inflation Reduction Act. Companies like Plug Power, focusing on green hydrogen, have seen stock surges and investments. Other nuclear-related companies have also experienced significant gains due to eligibility for the hydrogen tax credit, indicating a positive sentiment towards clean hydrogen production and infrastructure.
