The federal government’s Hydrogen Production Tax Credit (PTC), also known as 45V, provides the highest incentives for hydrogen produced using clean sources of power generation, like wind and solar. That might seem like great news for current and potential hydrogen producers looking to take advantage of the credit, since the U.S. has added significant renewable generation capacity in the last several years, but the reality is much different. In today’s RBN blog, we’ll explain how “additionality” fits into the “three pillars” of clean hydrogen, how it would be calculated under the proposed guidance, and some ways the rules might be adjusted to give hydrogen producers and power generators a little more flexibility.
