In one of the Biden administration’s final acts to advance decarbonization, and after more than two years of deliberation and heated debate, the Treasury Department issued the final requirements governing eligibility for the clean hydrogen tax credit on Friday.
At up to $3 per kilogram of clean hydrogen produced, this was the most generous subsidy in the 2022 Inflation Reduction Act, and it came with significant risks if the Treasury did not get the rules right. Hydrogen could be an important tool to help decarbonize the economy. But without adequate guardrails, the tax credit could turn it into a shovel that digs the U.S. deeper into a warming hole by paying out billions of dollars to projects that increase emissions rather than reducing them.
In the final guidelines, the Biden administration recognized the severity of this risk. It maintained key safeguards from the rules proposed in 2023, while also making a number of changes, exceptions, and other “flexibilities” — in the preferred parlance of the Treasury Department — that sacrifice rigorous emissions accounting in favor of making the program easier to administer and take advantage of.
For example, it kept a set of requirements for hydrogen made from water and electricity known as the “three pillars.” Broadly, they compel producers to match every hour of their operation with simultaneous clean energy generation, buy this energy from newly built sources, and ensure those sources are in the same general region as the hydrogen plant. Hydrogen production is extremely energy-intensive, and the pillars were designed to ensure that it doesn’t end up causing coal and natural gas plants to run more. But the final rules are less strict than the proposal. For example, the hourly matching requirement doesn’t apply until 2030, and existing nuclear plants count as new zero-emissions energy if they are considered to be at risk of retirement.
Finding a balance between limiting emissions and ensuring that the tax credit unlocks development of this entirely new industry was a monumental challenge. The Treasury Department received more than 30,000 comments on the proposed rule, compared to about 2,000 for the clean electricity tax credit, and just 89 for the electric vehicle tax credit. Senior administration officials told me this may have been the most complicated of all of the provisions in the IRA. In October, the department assured me that the rules would be finished by the end of the year.
Energy experts, environmental groups, and industry are still digesting the rule, and I’ll be looking out for future analyses of the department’s attempt at compromise. But initial reactions have been cautiously optimistic.
On the environmental side, Dan Esposito from the research nonprofit Energy Innovation told me his first impression was that the final rule was “a clear win for the climate” and illustrated “overwhelming, irrefutable evidence” in favor of the three pillars approach,…
