U.S. Department of the Treasury, IRS Release Guidance on
Hydrogen Production Credit to Drive American Innovation and
Strengthen Energy Security
December 22, 2023

WASHINGTON – Today the U.S. Department of the Treasury and Internal Revenue Service (IRS)
released proposed regulations on the Clean Hydrogen Production Credit established by the
Inflation Reduction Act (IRA), part of President Bidenʼs Investing in America agenda and a key
pillar of Bidenomics, which is creating good-paying jobs, strengthening energy security,
spurring private-sector investment to build the clean energy economy, and combatting the
climate crisis.
“The Biden-Harris Administration is driving American innovation in emerging industries to
create good-paying jobs, strengthen U.S. energy security, and help the U.S. clear hurdles in our
clean energy transition,” said U.S. Secretary of the Treasury Janet L. Yellen. “Incentives in
the Inflation Reduction Act are helping to scale production of low-carbon fuels like hydrogen
and cut emissions from heavy industry, a di icult-to-transition sector of our economy.”
“Today's announcement will further unprecedented investments in a new, American-led
industry as we aim to lead and propel the global clean energy transition,” said U.S. Secretary
of Energy Jennifer M. Granholm. “Hydrogen has the potential to clean up America's
manufacturing industry, power the transportation sector and shore up our energy security all
while delivering good-paying jobs and new economic opportunity to communities in every
pocket of America.”
“The Inflation Reduction Actʼs hydrogen tax credit will help build a clean hydrogen industry
that will be critical in reducing emissions from harder-to-decarbonize sectors like heavy
industry and heavy transportation,” said John Podesta, Senior Advisor to the President for
Clean Energy Innovation and Implementation.
While clean hydrogen holds considerable potential to reduce emissions across a range of
sectors and applications, conventional hydrogen production typically results in significant
climate pollution. The Clean Hydrogen Production Credit aims to make production of clean
hydrogen with minimal climate pollution more economically competitive and accelerate

development of the U.S. clean hydrogen industry. Todayʼs proposed regulations advance
those goals and will support the development of a robust U.S. clean hydrogen industry that
creates good-paying jobs, while also reducing carbon emissions.
The Treasury Departmentʼs Notice of Proposed Rulemaking (NPRM) provides definitions of key
terms in the statute, including lifecycle greenhouse gas emissions, qualified clean hydrogen,
and qualified clean hydrogen production facility. The safeguards outlined in the proposed
rules are critical to preventing the credit from subsidizing hydrogen production with higher
lifecycle greenhouse gas emissions than allowed by the statute.
The NPRM was developed a er extensive consultations with experts across the federal
government, particularly the Department of Energy (DOE), which oversees Argonne National
Labʼs administration of the GREET model, and the Environmental Protection Agency (EPA),
which administers the Clean Air Act. The proposed regulations provide guidance based on the
statuteʼs references to the Clean Air Act and the GREET model.
The NPRM also takes comment on important issues where Treasury anticipates providing
further clarity and certainty in the final rules. The NPRM will be open for public comment for
60 days once it is published in the Federal Register, and Treasury and the IRS will carefully
consider comments before issuing final rules.

T HE IRA CLEAN HYDROGEN PRODUCT ION CREDIT
The IRA establishes a Clean Hydrogen Production Credit with four technology-neutral credit
tiers based on the emissions rate of a hydrogen production process. For hydrogen production
facilities meeting prevailing wage and registered apprenticeship requirements, the amount of
the credit ranges from $.60 per kilogram (kg) of hydrogen produced to $3 per kg of hydrogen,
depending on the lifecycle emissions of the hydrogen production.
The statute requires that credit eligibility be determined under the Clean Air Actʼs definition of
lifecycle greenhouse gas emissions, including significant indirect emissions, through the point
of production. The statute also requires that lifecycle greenhouse gas emissions be
determined under the most recent GREET model. The credit is available for 10 years starting
on the date that a hydrogen production facility is placed into service for projects that begin
construction before 2033, meaning it will remain available for some facilities well into the
2040s.

The NPRM is technology-neutral and describes how taxpayers must use the 45VH2-GREET
model developed by Argonne National Laboratory to determine lifecycle greenhouse gas
emissions. The statute also requires that to claim the credit, a taxpayer must have production
and sale, or use of clean hydrogen verified by a qualified, unrelated third party. For taxpayers
unable to use the 45VH2-GREET model because their hydrogen production technology and/or
feedstock is not included, those taxpayers may petition the Secretary of the Treasury for a
provisional emissions rate analogous to the lifecycle greenhouse gas emissions rate
calculated using 45VH2-GREET.

HYDROGEN PRODUCED USING ELECT RICIT Y
The Treasury Departmentʼs proposed rules describe how taxpayers may use energy attribute
certificates (EACs), which demonstrate the purchase of clean power, to assess and document
qualification for a particular credit tier. The proposed rules explain the three criteria that must
be reflected in EACs being purchased by hydrogen producers claiming the tax credit:
New clean power (Incrementality): Clean power generators that began commercial
operations within three years of a hydrogen facility being placed into service are
considered new sources of clean power. Generation resulting from a generatorʼs newly
added capacity (“uprates”) are also considered new sources of clean power. The proposed
rules also request comments on approaches by which generation from existing clean
power generators could be considered to meet the requirements for new clean power
under certain circumstances.
Deliverable clean power: Clean power must be sourced from the same region as the
hydrogen producer, as derived from DOEʼs 2023 National Transmission Needs Stud

y.

The proposed rules also request comment on how to consider transmission of clean
power between regions.
New, deliverable clean power generated annually, with a phase-in to hourly
generation (Time-matching): EACs will generally need to be matched to production on
an hourly basis—meaning that the claimed generation must occur within the same hour
that the electrolyzer claiming the credit is operating. The proposed rules include a
transition to allow annual matching until 2028 when hourly tracking systems are expected
to be more widely available and seeks comment on this transition timeline.

The proposed rules detail eligibility requirements for hydrogen production from landfill gas in
certain circumstances. Treasury and IRS anticipate finalizing rules in which additional
hydrogen production pathways using renewable natural gas (RNG) and fugitive methane, such
as coal mine or coal bed methane, qualify and are seeking public comment on conditions for
qualification while adhering to the standards in the statute.

SUPPORT ING ANALYSIS
The NPRM is supported by a technical paper from DOE that considers how to assess lifecycle
greenhouse gas emissions associated with hydrogen production using electricity. Treasury is
also citing to a letter from EPA to Treasury explaining how its prior interpretations of the
Clean Air Act could inform Treasuryʼs implementation of the statute given the statutory
reference to the Clean Air Act. In addition to the Treasury Departmentʼs NPRM, DOE is
releasing the 45VH2-GREET model that taxpayers will use to calculate the 45V credit and an
updated GREET user manual.
