A federal law cuts 5 years off the deadline to qualify for the hydrogen production tax credit

What the hydrogen production tax credit pays for

The hydrogen production tax credit rules, created by section 45V of the tax code and finalized by the Treasury Department and the Internal Revenue Service on January 10, 2025, pay a company for how clean its hydrogen is, not simply for making it. Carbon dioxide is the gas that traps heat and warms the planet, and the credit is priced entirely by how much of it escapes while making each kilogram of hydrogen. The base credit is 0.60 dollars a kilogram for hydrogen made the dirtiest way that still qualifies. It rises to as much as 3.00 dollars a kilogram, a 5 times increase, once a company also meets prevailing wage and apprenticeship rules, requirements that workers are paid a government set wage and that some labor hours go to registered apprentices. Make hydrogen that releases more than 4 kilograms of carbon dioxide for every kilogram produced, and a project earns no credit at all. The credit runs for 10 years once a facility starts operating.

A federal law cut 5 years off the deadline to qualify

A separate 2025 law changed something the final rule text alone does not mention. Reading the actual codified statute directly, not only the regulation, shows that P.L. 119-21 moved the deadline for a hydrogen project to begin construction and still qualify for any credit, from January 1, 2033 to January 1, 2028, a 5 year cut. Begin construction is the legal term for breaking ground in a way regulators recognize, not simply announcing a project. Measured from this research date, that leaves about 16 months for a project that has not yet broken ground to start, or lose access to the credit no matter how clean its hydrogen eventually is. The base credit and emissions tiers decide how much a project earns. The deadline decides whether it earns anything at all.

The emissions tiers reward the cleanest hydrogen by far

The final rule sorts projects into 4 emissions tiers before the wage multiplier is applied at all. The dirtiest tier that still qualifies, hydrogen made releasing 2.5 to 4 kilograms of carbon dioxide for every kilogram produced, earns only 20% of the 0.60 dollar base rate. The cleanest tier, below 0.45 kilograms, earns the full base rate before any multiplier. Only after that base amount is set does the 5 times wage and apprenticeship multiplier apply, producing the final range from 0.60 to 3.00 dollars a kilogram. A project has to clear the cleanest emissions tier and meet the wage rules together to reach the top payment. Clearing only one earns a smaller fraction of it.

Treasury says the rule gives builders certainty to keep going

The Treasury Department says it read close to 30,000 public comments before settling on the final version of the rule. Wally Adeyemo, Deputy Secretary of the Treasury, said the rule reflects that feedback.

These rules incorporate helpful feedback from companies planning investments which will drive significant deployment of clean hydrogen to power heavy industry and help create good-paying jobs.

The extensive revisions we've made in this final rule provide the certainty that hydrogen producers need to keep their projects moving forward.
