Carbon Capture and Sequestration Tax Credit
(“Section 45Q”) Legislation in the 117th
Congress
July 28, 2021
The tax credit for carbon oxide sequestration (Internal Revenue Code [IRC] Section 45Q) is intended to
incentivize investment in carbon capture and sequestration technologies (also known as carbon capture
and storage [CCS]). While deployment of CCS technology has been limited to date, academics and
industry experts (see here, here, and here) believe the technology has great potential for achieving GHG
emissions reductions. One barrier to CCS deployment has been cost. Tax credits, such as the current-law
tax credit in Section 45Q, are one policy option for addressing this barrier. There are a number of
proposals in the 117th Congress to modify and expand Section 45Q. This Insight highlights the key
changes that would be made to Section 45Q across different legislative proposals.

Legislative Proposals in the 117 th Congress to Modify
Section 45Q
Proposals introduced on a largely stand-alone basis are summarized and compared in Table 1.

Proposed Modifications to Section 45Q in Broad Energy
Tax Proposals
The Senate Finance Committee has considered comprehensive energy tax reform legislation, the Clean
Energy for America Act. The Administration has also proposed substantial energy tax policy changes. In
the House, the Growing Renewable Energy and Efficiency Now (GREEN) Act proposes substantive
changes to current-law energy tax policy. Each of these proposals would make changes to Section 45Q, as
summarized in Table 2.
Table 2. Proposed Modifications to Section 45Q in Comprehensive Energy Tax Policy
Proposals
S. 1298—Clean Energy for
America Act

Biden Administration
Proposal

For direct air capture projects,
increase credit to $175 per
metric ton for carbon oxide
captured and stored and to $150
per ton for carbon oxide
captured and used. Both amounts
inflation-adjusted after 2026

For “hard-to-abate” industrial
sources, increase credit by $35
per metric ton (total credit of
$85 per metric ton in 2026)

Expiration
Date

Credit to phase out when sector
emissions (e.g., electricity, other
industry) are 25% (or less) of
2021 emissions; phaseout does
not apply to direct air capture
facilities

Start of construction deadline
extended through 2030

Eligible
Facilities

Minimum capture amounts for
direct air capture eliminated;
minimum capture requirements
revised such that at least 75% of
carbon oxide at electricity
generating facility must be
captured; 50% for other facilities.
Credit cannot be claimed for
facilities that begin construction
after 2026 for carbon oxide used
as a tertiary injectant (i.e., for
enhanced oil recovery)

Direct Pay

Provides direct pay option
(effective December 30, 2020)

Provides direct pay option

Other
Provisions

Impose wage and workforce
requirements (prevailing wage and
apprenticeship program
requirements). Effective after
December 31, 2021

Credits paired with “strong labor
standards”

Notes: The Joint Committee on Taxation has released a technical summary of S. 1298.

Other legislation, the Save America’s Clean Energy Jobs Act (S. 985), would allow certain energy-related
tax credits, including Section 45Q, to be received as direct pay (issues related to allowing tax credits to be
received as payments are discussed in this CRS report).
There are also proposals that would repeal all tax incentives that support the use of fossil fuels. The End
Polluter Welfare Act of 2021 (S. 1167/H.R. 2102) would terminate Section 45Q. Carbon capture is not
universally viewed as an effective tool for achieving long-run environmental or climate policy objectives.
Some environmental advocates oppose the policy because it supports continued use of fossil fuels.
