Carbon Capture Coalition Comments on 45Q Safe Harbor Notice

On October 30, 2026, the Carbon Capture Coalition submitted comments to the U.S. Treasury on Notice 2026-50, which extends the 45Q carbon capture tax credit safe harbor to enhanced oil recovery (EOR) projects and lengthens the compliance timeline. The development matters to CCUS project participants and their suppliers because the notice provides clearer policy guidance, while the practical implications for individual projects still warrant review.

Notice Extends Safe Harbor Coverage to EOR

The Treasury and IRS issued Notice 2026-50, expanding the scope of the 45Q safe harbor to include EOR projects and extending the compliance timeline. The Carbon Capture Coalition submitted comments on the notice on October 30, 2026. According to the information provided, the notice offers clearer policy guidance and investment certainty for the CCUS industry.

Where Project Decisions Could Be Affected

EOR Project Planning and Investment

From an industry perspective, the inclusion of EOR projects may affect how project sponsors assess potential access to the 45Q safe harbor and schedule compliance work. The longer timeline may also influence investment planning. The information provided does not specify eligibility conditions or the length of the extension, so the effect on any particular project remains to be assessed.

Engineering, Equipment and Delivery

Analysis suggests that engineering contractors and equipment suppliers could see changes in project schedules or procurement discussions if sponsors revise their plans in response to the notice. Suppliers may need to monitor project-specific specifications and delivery schedules; the notice alone does not establish that orders or delivery dates have changed.

Compliance and Project Documentation

For teams supporting 45Q compliance, the expanded scope and extended timeline may make it useful to revisit how project records and schedules are organized. The supplied information does not identify required documents or filing procedures, so any documentation needs should be checked against the relevant official guidance.

Questions for Project Teams and Suppliers

Confirm Project Coverage

Project teams can review the notice and subsequent official guidance to assess whether a proposed or existing EOR project falls within the safe harbor. The supplied summary does not establish that every EOR project qualifies.

Check the Applicable Timeline

Businesses may want to verify the extended compliance dates and how they apply to individual projects before adjusting investment, procurement or delivery schedules. The input does not state the revised dates or describe how the extension operates.

Align Records and Commercial Plans

Project participants and suppliers can review relevant project records, contract schedules and procurement assumptions as more details become available. Any changes to documentation or commercial arrangements should reflect verified guidance and the circumstances of the project, rather than an assumption that the notice imposes a particular new requirement.

From Published Notice to Project-Level Application

At this stage, the notice is best understood as a stated change in safe harbor scope and timing, accompanied by an industry submission, rather than proof of a specific outcome for every project. The content of the coalition's comments is not described in the supplied information. Further official guidance and industry feedback may help clarify how the changes are applied and whether project participants adjust their plans.

A More Defined Framework, With Details to Verify

The expansion to EOR and the longer compliance timeline provide a basis for CCUS participants to reassess project planning. The practical response is to examine the applicable official text and monitor subsequent clarification before treating potential investment, procurement or delivery effects as settled.
