Which Federal Instruments Follow a Battery Facility When It Stops Making EV Cells

Each instrument tethers to a different legal object. They separate cleanly and should be traced separately.

The §45X Credit Follows the Component, Not the Application

Section 45X(a)(1) allows the credit for each "eligible component" produced and sold to an unrelated person. Section 45X(c)(5)(A) defines qualifying battery components: electrode active materials, battery cells, and battery modules. The cell credit is $35/kWh. The module credit is $10/kWh (cells included) or $45/kWh (cells excluded).

The statute conditions eligibility on what the component is, not what it powers. Electrochemical structure, energy density (≥100 Wh/L for cells), minimum capacity (≥12 Wh for cells). No subsection of §45X requires that a cell or module be destined for an EV, a grid-storage system, a data-center UPS, or anything else. The eligibility conditions are enumerated exhaustively, and downstream application is absent from the list. A facility producing §45X-eligible cells for EV packs that shifts to producing §45X-eligible cells for stationary storage does not lose eligibility on that basis.

I should be explicit: this conclusion is an inference from statutory structure rather than a statement in agency guidance. The inference is straightforward, but it is an inference.

One new condition does apply, and it matters more than the end-use question. Section 45X(c)(1)(C), added by the One Big Beautiful Bill Act (Pub. L. 119-21, enacted July 4, 2025), excludes from "eligible component" any property that includes material assistance from a prohibited foreign entity as defined in §7701(a)(52). The MACR thresholds for §45X battery components, set by §7701(a)(52)(C)(i)(IV), start at 60% non-PFE direct material cost in 2026, rise to 85% after 2029, with the steepest single step (+10 percentage points) arriving in 2029. This PFE screen applies to the manufacturer's eligible components regardless of what the cells power. A converted facility's §45X eligibility now carries its own supply-chain compliance requirement, independent of anything in §30D or §48E. The credit follows the component. The compliance obligation follows the credit.

FEOC/PFE Compliance Pressure Changes Origin, Not Magnitude

The §30D FEOC mechanism that drove supply-chain diligence for EV batteries is closed. Two independent PFE screens now apply to the same output, one binding the manufacturer and one binding the downstream buyer.

The original pull ran through §30D(d)(7), which excluded from "new clean vehicle" any vehicle whose battery contained components manufactured or assembled by a foreign entity of concern. An OEM wanting its vehicles to qualify for §30D had to trace its battery supply chain and certify FEOC-free status. Section 30D(h), as amended by OBBBA, eliminated the §30D credit for vehicles acquired after September 30, 2025. That mechanism is done. Facilities converting away from EV output are not uniquely affected; the §30D compliance pull ended across the entire battery supply chain nine months ago.

The replacement pull, for facilities converting to stationary storage output, runs through §48E(c)(3), also added by OBBBA. This excludes energy storage technology from the clean electricity investment credit if construction begins after December 31, 2025, and includes material assistance from a PFE. The construction-begins trigger applies to the downstream storage project, not to the cell manufacturing facility itself. The MACR thresholds for energy storage under §7701(a)(52)(B)(ii) are 55% in 2026, rising to 75% after 2029.

The obligated party shifted. Under §30D, the compliance obligation sat with the vehicle manufacturer and flowed upstream contractually. Under §48E, the obligation sits with the project taxpayer claiming the investment credit for the storage asset. The cell manufacturer is not directly regulated by §48E. But a storage project developer seeking §48E will require PFE/MACR documentation from its cell supplier as a procurement condition, because it has no other way to demonstrate its own compliance. The pull still reaches the facility. It arrives through a different buyer, under different thresholds, on a different schedule.

For cathode-dependent chemistries where CAM sourcing is the decisive variable, the binding constraint will be the §45X manufacturer threshold. It is higher, it rises faster, and it applies regardless of whether the downstream buyer claims any credit at all.

The LPO Loan: Precisely Stated and Precisely Unanswered

BlueOval SK's $9.63 billion ATVM loan, closed December 2024, was publicly described by DOE as supporting EV battery cell manufacturing. Ford's May 21, 2026 Form 8-K disclosed that $7.84 billion had been advanced before the ownership separation and that Ford assumed a $3.805 billion promissory note for one Kentucky plant.

The public record here is more informative than commonly assumed, and less conclusive than anyone needs it to be.

Ford's Exhibit 10, the post-separation Loan Arrangement and Reimbursement Agreement filed with redactions, defines "Product" broadly: battery and battery energy storage products, systems, and services, encompassing cells, modules, and containers for both stationary storage and EV use. That definition accommodates a mixed-use or storage-oriented facility on its face.

The same agreement contains a program-requirements covenant that points the other direction. The borrower must not cause manufactured components to fall outside the definition of advanced technology vehicles or "qualifying components" under 10 CFR 611.2. The ATVM statute, 42 USC §17013, defines qualifying components as components designed for advanced technology vehicles. The agreement restricts material changes to the nature or scope of the project without DOE consent and explicitly contemplates that such consents may be sought for mixed-use operation.

A broad product definition coexists with an ATVM-rooted covenant and a DOE consent mechanism. Whether DOE has granted, conditioned, or been asked for consent to a product-scope change is not in the public record. No conclusion about loan risk or compliance is supportable from what is disclosed. The agreement was written to accommodate the question. Whether the question has been asked, and what DOE answered, remains behind the redaction line.

Structural Unknowns

Four gaps bound this analysis and should be named explicitly.

§45X credit claims are protected under Section 6103. No facility-level claims registry exists. Whether a converted facility is actually claiming §45X credits, and at what volume, is not observable from outside.

Treasury effective-control guidance under §7701(a)(51) is due by December 31, 2026. No NPRM has been published through July 2026. Until this guidance lands, the entity-level determination that feeds every PFE threshold remains interim.

Interim MACR guidance — IRS Notice 2026-15 is the operative document, with IR-2026-23 providing reliance instructions. Both are subject to revision when proposed regulations and safe-harbor tables issue (statutory deadline: December 31, 2026, per §7701(a)(52)(D)(iii)). Compliance architectures built on interim guidance carry revision risk by definition.

LPO loan modification terms, DOE consent actions, and redacted covenant language for BlueOval SK and Ford Energy Battery remain nonpublic.

The §45X credit and the PFE compliance architecture can be traced through statute to defensible conclusions. The LPO loan question is bounded by an agreement the public can read only in part, and it stays open until someone discloses what sits behind the redactions.
