SECTION 3. REQUEST FOR

COMMENTS

The Treasury Department and the IRS request comments on questions arising under § 45V (and the associated clean hydrogen production incentives in §§ 45 and 48) and under § 45Z that should be addressed in guidance. Commenters are encouraged to specify the issues on which guidance is needed most quickly as well as the most important issues on which guidance is needed. In addition to general comments, the Treasury Department and the IRS request comments that address the following specific questions:

.01 Credit for Production of Clean Hydrogen .

(1) Clean Hydrogen . Section 45V provides a definition of the term “qualified clean hydrogen.” What, if any, guidance is needed to clarify the definition of qualified clean hydrogen?

(a) Section 45V defines “lifecycle greenhouse gas emissions” to “only include emissions through the point of production (well-to-gate).” ³ Which specific steps and emissions should be included within the well-to-gate system boundary for clean hydrogen production from various resources?

(b)(i) How should lifecycle greenhouse gas emissions be allocated to co-products from the clean hydrogen production process? For example, a clean hydrogen producer may valorize steam, electricity, elemental carbon, or oxygen produced alongside clean hydrogen.

(ii) How should emissions be allocated to the co-products (for example, system expansion, energy-based approach, massbased approach)?

(iii) What considerations support the recommended approaches to these issues?

(c)(i) How should lifecycle greenhouse gas emissions be allocated to clean hydrogen that is a by-product of industrial

1 The higher credit amount also applies if the construction of the facility begins prior to the date that is 60 days after the Secretary publishes guidance with respect to the prevailing wage and apprenticeships requirements of § 45V(e)(3)(A) and (4), unless the facility is altered or repaired after that date. The IRA also provides an election for a taxpayer to receive a direct payment or to transfer the credit. Similar provisions were added by the IRA to several other Code provisions. See Notice 2022-51 requesting comments on prevailing wage and apprenticeship requirements and Notice 2022-50 requesting comments on direct payment and transferability issues for general applicability to these several Code sections.

2 These prevailing wage and apprenticeship requirements are provided in § 45Z(f)(6) and (f)(7). Similar provisions were added by the IRA to several other Code sections. See Notice 202251 requesting comments on prevailing wage and apprenticeship requirements. General comments pertaining to the prevailing wage and apprenticeship requirements should be submitted in response to Notice 2022-51.

3 The well-to-gate system boundary for hydrogen production includes emissions associated with feedstock growth, gathering, and/or extraction; feedstock delivery to a hydrogen production facility; conversion of feedstock to hydrogen at a production facility; generation of electricity consumed by a hydrogen production facility (including feedstock extraction for electricity generation, feedstock delivery, and the electricity generation process itself); and sequestration of carbon dioxide generated by a hydrogen production facility.

processes, such as in chlor-alkali production or petrochemical cracking?

(ii) How is byproduct hydrogen from these processes typically handled (for example, venting, flaring, burning onsite for heat and power)?

(d) If a facility is producing qualified clean hydrogen during part of the taxable year, and also produces hydrogen that is not qualified clean hydrogen during other parts of the taxable year (for example, due to an emissions rate of greater than 4 kilograms of CO2-e per kilogram of hydrogen), should the facility be eligible to claim the § 45V credit only for the qualified clean hydrogen it produces, or should it be restricted from claiming the § 45V credit entirely for that taxable year?

(e) How should qualified clean hydrogen production processes be required to verify the delivery of energy inputs that would be required to meet the estimated lifecycle greenhouse gas emissions rate as determined using the GREET model or other tools if used to supplement GREET?

(i) How might clean hydrogen production facilities verify the production of qualified clean hydrogen using other specific energy sources?

(ii) What granularity of time matching (that is, annual, hourly, or other) of energy inputs used in the qualified clean hydrogen production process should be required?

(2) Alignment with the Clean Hydro- gen Production Standard . On September 22, 2022, the Department of Energy (DOE) released draft guidance for a Clean Hydrogen Production Standard (CHPS) developed to meet the requirements of § 40315 of the Infrastructure Investment and Jobs Act (IIJA), Public Law 117-58, 135 Stat. 429 (November 15, 2021). ⁴ The CHPS draft guidance establishes a target lifecycle greenhouse gas emissions rate for clean hydrogen of no greater than 4.0 kilograms CO2-e per kilogram of hydrogen, which is the same lifecycle greenhouse gas emissions limit required by the § 45V credit. For purposes of the § 45V credit, what should be the definition or specific boundaries of the well-to-gate analysis?

(3) Provisional Emissions Rate . For hydrogen production processes for which

a lifecycle greenhouse gas emissions rate has not been determined for purposes of § 45V, a taxpayer may file a petition with the Secretary for determination of the lifecycle greenhouse gas emissions rate of the hydrogen the taxpayer produces.

(a) At what stage in the production process should a taxpayer be able to file such a petition for a provisional emissions rate?

(b) What criteria should be considered by the Secretary in making a determination regarding the provisional emissions rate?

(4) Recordkeeping and Reporting . (a) What documentation or substantiation do taxpayers maintain or could they create to demonstrate the lifecycle greenhouse gas emissions rate resulting from a clean hydrogen production process?

(b) What technologies or methodologies should be required for monitoring the lifecycle greenhouse gas emissions rate resulting from the clean hydrogen production process?

(c) What technologies or accounting systems should be required for taxpayers to demonstrate sources of electricity supply?

(d) What procedures or standards should be required to verify the production (including lifecycle greenhouse gas emissions), sale and/or use of clean hydrogen for the § 45V credit, § 45 credit, and § 48 credit?

(e) If a taxpayer serves as both the clean hydrogen producer and the clean hydrogen user, rather than selling to an intermediary third party, what verification process should be put in place (for example, amount of clean hydrogen utilized and guarantee of emissions or use of clean electricity) to demonstrate that the production of clean hydrogen meets the requirements for the § 45V credit?

(f) Should indirect book accounting factors that reduce a taxpayer’s effective greenhouse gas emissions (also known as a book and claim system), including, but not limited to, renewable energy credits, power purchase agreements, renewable thermal credits, or biogas credits be considered when calculating the § 45V credit?

(g) If indirect book accounting factors that reduce a taxpayer’s

effective greenhouse gas emissions, such as zero-emission credits or power purchase agreements for clean energy, are considered in calculating the § 45V credit, what considerations (such as time, location, and vintage) should be included in determining the greenhouse gas emissions rate of these book accounting factors?

(5) Unrelated Parties . (a) What certifications, professional licenses, or other qualifications, if any, should be required for an unrelated party to verify the production and sale or use of clean hydrogen for the § 45V credit, § 45 credit, and § 48 credit?

(b) What criteria or procedures, if any, should the Treasury Department and the IRS establish to avoid conflicts of interest and ensure the independence and rigor of verification by unrelated parties?

(c) What existing industry standards, if any, should the Treasury Department and the IRS consider for the verification of production and sale or use of clean hydrogen for the § 45V credit, § 45 credit, and § 48 credit?

(6) Coordinating Rules . (a) Application of certain § 45 rules . (i) Section 45V(d)(3) includes a reduction for the § 45V credit when tax-exempt bonds are used in the financing of the facility using rules similar to the rule under § 45(b)(3)). What, if any, additional guidance would be helpful in determining how to calculate this reduction?

(ii) Section 45V(d)(1) states that the rules for facilities owned by more than one taxpayer are similar to the rules of § 45(e)(3). How should production from a qualified facility with more than one person holding an ownership interest be allocated?

(b) Coordination with § 48 . (i) What factors should the Treasury Department and the IRS consider when providing guidance on the key definitions and procedures that will be used to administer the election to treat clean hydrogen production facilities as energy property for purposes of the § 48 credit?

(ii) What factors should the Treasury Department and the IRS consider when providing guidance on whether a facility

Bulletin No. 2022–47 485 November 21, 2022

is “designed and reasonably expected to produce qualified clean hydrogen?”

(c) Coordination with § 45Q . Are there any circumstances in which a single facility with multiple unrelated process trains could qualify for both the § 45V credit and the § 45Q credit notwithstanding the prohibition in § 45V(d)(2) preventing any § 45V credit with respect to any qualified clean hydrogen produced at a facility that includes carbon capture equipment for which a § 45Q credit has been allowed to any taxpayer?

(7) Please provide comments on any other topics related to § 45V credit that may require guidance.

.02 Clean Fuel Production Credit (§ 45Z) .

(1) Sale Definition . (a) What factors should the Treasury Department and the IRS consider in determining whether an unrelated person purchases transportation fuel for use in a trade or business for purposes of § 45Z(a)(4)(B)?

(b) What factors should the Treasury Department and the IRS consider in determining whether fuel is sold at retail for purposes of § 45Z(a)(4)(C)?

(2) Establishment of Emissions Rate for Sustainable Aviation Fuel . Section 45Z(b) (1)(B)(iii) provides that the lifecycle greenhouse gas emissions of sustainable aviation fuel shall be determined in accordance with the Carbon Offsetting and Reduction Scheme for International Aviation or “any similar methodology which satisfies the criteria under § 211(o)(1)(H) of the Clean Air Act (42 U.S.C. 7545(o)(1)(H)), as in effect on the date of enactment of this section.” What methodologies should the Treasury Department and IRS consider for the lifecycle greenhouse gas emissions of sustainable aviation fuel for the purposes of § 45Z(b)(1)(B)(iii)(II)?

(3) Provisional Emissions Rates . Section 45Z(b)(1)(D) allows the taxpayer to file a petition with the Secretary for determination of the emissions rate for a transportation fuel which has not been established.

(a) At what stage in the production process should a taxpayer be able to file a petition for a provisional emissions rate?

(b) What criteria should be considered by the Secretary to determine the provisional emissions rate?

(4) Special Rules . Section 45Z(f) (1) provides several requirements for a

taxpayer to claim the § 45Z credit, including for sustainable aviation fuel a certification from an unrelated party demonstrating compliance with the general requirements of the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) or in the case of any similar methodology, as defined in § 45Z(b)(1) (B)(iii)(II), requirements that are similar to CORSIA’s requirements. With respect to this certification requirement for sustainable aviation fuel, what certification options and parties should be considered to support supply chain traceability and information transmission requirements?

(5) Coordinating Rules . Section 45Z(f) (4) states that under regulations prescribed by the Secretary, rules similar to the rules of § 52(d) apply in the case of estates and trusts. Section 45Z(f)(5) states that rules similar to § 45Y(g)(6) apply to patrons of agricultural cooperatives. Section 45Z(f) (6)(A) states that rules similar to the rules of § 45(b)(7) apply for the prevailing wage requirement. Section 45Z(f)(7) states that rules similar to the rules of § 45(b) (8) apply for the apprenticeship requirement. Is the application of the cross-referenced rules for purposes of the § 45Z credit adequately clear? What aspects of the cross-referenced rules should apply to the § 45Z credit without modification and what aspects should be modified?

(6) Multiple Owners . How should production from a qualifying facility with more than one person having an ownership interest in such facility be allocated to such persons for purposes of § 45Z(f) (2)? Should rules similar to the rules under § 45(e)(3) apply for this purpose? If so, which aspects of § 45(e)(3) should apply without modification for this purpose and which aspects should be modified?

(7) Please provide comments on any other topics related to § 45Z credit that may require guidance.
