On April 30, 2024, the Department of the Treasury issued final regulations on tax credit transfers that allow hydrogen producers to sell tax credits earned under § 45V of the Inflation Reduction Act (IRA). Section 6418 of the Internal Revenue Code and the final regulation issued thereunder allow credit purchasers to use purchased credits to offset their tax liability. Credit sellers will be able to sell credits that they would not otherwise be able to use due to insufficient tax liability. Given such powerful incentives, many energy producers are wondering how to add “green” hydrogen (discussed below) to their portfolios by powering hydrogen facilities with wind turbines and solar panels. Here, we discuss what wind and solar producers should keep in mind as they plan, negotiate, and begin developing hydrogen plants powered by renewable energy, with a particular focus on site control.
