The Treasury Department and IRS have released final regulations for the Clean Hydrogen Production Tax Credit under Internal Revenue Code Section 45V. This tax credit is provided for the production of clean hydrogen at qualified facilities for 10 years from the service commencement date. The regulations focus on technology-neutral qualification criteria, with the credit amount based on the kilograms of qualified clean hydrogen produced and the applicable rate determined by the GHG emissions rate. The Final Regulations offer leniency in the 'three pillars' of incrementality, temporal matching, and deliverability for hydrogen production using clean power. Additionally, guidance is given on claiming the credit for hydrogen produced using methane reformation technologies, including rules for calculating lifecycle GHG emissions and introducing Gas Energy Attribute Certificates. A book-and-claim framework is endorsed for hydrogen produced using RNG or coal mine methane systems, permitting taxpayers to claim use of these sources without a direct pipeline connection. Overall, the regulations aim to provide flexibility and clarity for taxpayers seeking to benefit from the Clean Hydrogen Production Tax Credit.
