The U.S. Department of the Treasury has released final rules for the section 45V Clean Hydrogen Production Tax Credit, established by the Inflation Reduction Act. These rules bring significant changes aimed at advancing the clean hydrogen industry and facilitating project development. They offer clarity on eligibility criteria for hydrogen producers using various sources, such as electricity, natural gas with carbon capture, renewable natural gas, and coal mine methane. The final rules, developed in collaboration with expert agencies after considering public feedback, are designed to support the growth of clean hydrogen deployment in sectors like heavy industry and transportation. Deputy Secretary of the Treasury, Wally Adeyemo, highlighted the importance of these rules in driving investments and creating jobs. The regulations also focus on enhancing the accuracy of emissions calculations, ensuring compliance with standards, and promoting investment certainty. Notable aspects include the elimination of certain administrative requirements, guidelines for calculating lifecycle GHG emissions, and the allowance for all types of hydrogen producers to use a specific model for consistency. Moreover, the rules aim to boost the development of natural gas alternatives like RNG and coal mine methane, providing detailed information requirements for 'book-and-claim' systems. By addressing industry feedback and streamlining processes, the U.S. aims to establish leadership in green hydrogen production and drive economic opportunities across the country.
