After over a year of deliberation and thousands of public comments, the US Treasury finalized rules for implementing the IRA's Clean Hydrogen Production Tax Credit, Section 45V. This tax credit aims to stimulate the growth of the clean hydrogen industry in the United States by offering lucrative incentives to hydrogen producers that significantly decrease greenhouse gas emissions. Alongside $7 billion in federal funding allocated for regional hydrogen hubs and another $1 billion for demand-side initiatives, the rules have been met with significant interest, drawing nearly 30,000 comments. The finalized rules maintain the 'three pillars' requirements for aligning low-emitting electric power generation with hydrogen production but introduce adjustments such as allowing existing nuclear plants to power hydrogen production and extending deadlines for clean power generation matching. They clarify how lifecycle GHG emissions will be determined using the 45VH2-GREET model and establish pathways for producing creditable hydrogen from biogas, renewable natural gas, and fugitive methane. The rules also discuss how the incoming Trump administration may impact these regulations, potentially seeking to rescind or modify them. However, the administration would face procedural hurdles to make significant changes to the rules. The article concludes by providing information on the hydrogen tax credit basics, including credit amounts based on carbon intensity and the expiration date of the credit in 2033. Overall, the article highlights the efforts to support clean hydrogen production in the US, the implications of the finalized rules, and the potential influence of the incoming administration on hydrogen policies and incentives.
