The Tax Credit Hiding in Your Grain Field

A new BASF-Arva partnership gives US biorefineries verified low-CI grain data to unlock the 45Z clean fuel tax credit

2 Jun 2026

US biofuel producers now have a clearer path to one of clean energy's most valuable tax incentives, and it runs through the grain field. Announced on May 26, 2026, a strategic collaboration between BASF and Arva links digital farming tools with biorefinery compliance systems to establish end-to-end traceability for low-carbon-intensity grain across the US supply chain. At stake is Section 45Z, the federal Clean Fuel Production Credit, which ties per-gallon incentives directly to the carbon intensity of a producer's feedstock.

Roughly half of US ethanol production depends on commercially sourced grain, yet most plants have lacked the field-level data needed to maximize 45Z claims. The partnership addresses that gap directly. BASF's xarvio BIOENERGY platform integrates with Arva's CropForce system to generate verified, audit-ready carbon intensity scores across both farmer-direct and commercial grain channels, with double-counting prevention built in.

Farmers stand to benefit. Those already applying regenerative practices, including cover cropping, reduced tillage, and precision nutrient management, can now have those outcomes quantified, verified, and linked to potential financial recognition without changing existing grain flows. "By integrating our growing network of commercial grain partners with BASF's BIOENERGY platform, we can help plants recognize more low-CI bushels," said Ryan Pearcy, Managing Director of Biofuels and Renewable Energy at Arva.

Regulatory timing sharpens the deal's significance. Treasury Department rules governing 45Z remain unfinalized, and the US House passed a credit extension in May 2026, with Senate action still pending. Companies that build verified feedstock pipelines now will be better positioned to capture full credit value once implementing regulations arrive. The collaboration also satisfies California Air Resources Board requirements under the Low Carbon Fuel Standard, giving Midwestern producers supplying California-bound fuel a second compliance pathway from a single data system.

With US biofuel mandates at record levels under the 2026 Renewable Fuel Standard, feedstock traceability is becoming a competitive edge. For American farmers and ethanol plants alike, clean production credentials are beginning to move markets, and the regulatory decisions still ahead could determine how quickly that shift accelerates.
