US bill would extend expired biofuel credits

New York, 1 May (Argus) — Legislation soon to be introduced in the US House would extend expired biofuel incentives through 2026, potentially providing a reprieve to refiners that have curbed production this year because of policy uncertainty. The bill, which will be sponsored by US representative Mike Carey (R-Ohio) and some other Republicans on the powerful House Ways and Means Committee, according to a person familiar, could be introduced as soon as today. It would prolong both the long-running $1/USG for blenders of biomass-based diesel and a separate incentive that offers up to $1.01/USG for producers of cellulosic ethanol. The credits expired at the end of last year but under the proposal would be extended through both 2025 and 2026. The incentives would run alongside the Inflation Reduction Act's new "45Z" credit for clean fuel producers, which offers a sliding scale of benefits based on carbon intensity, though the bill would prevent double claiming of credits, according to bill text shared with Argus . The 45Z credit is less generous across the board to road fuels — offering $1/USG only for carbon-neutral fuels and much less for crop-based diesels — and is still in need of final rules after President Joe Biden's administration issued only preliminary guidance around qualifying. The proposal then would effectively offer a more generous alternative through 2026 for biodiesel, renewable diesel, and cellulosic ethanol but not for other fuels that can claim the technology-neutral 45Z incentive. That could upend the economics of renewable fuel production. Vegetable oil-based diesels for instance could claim the blenders credit and earn more than aviation fuels that draw from the same feedstocks. According to Argus Consulting estimates, aviation fuels derived from wastes like distillers corn oil and domestic used cooking should still earn more than $1/USG this year, conversely, since 45Z is more generous to aviation fuels. Extending the biodiesel blenders credit would also allow foreign fuel imports to again claim federal subsidies, a boost for Finnish refiner Neste and the ailing Canadian biofuel startup Braya Renewable Fuels but a controversial provision for US refiners and feedstock suppliers. The 45Z incentive can only be claimed by US producers. The blenders incentive is also popular among fuel marketer groups, which have warned that shifting subsidies to producers could up fuel costs. The proposal adds to a contentious debate taking place across the biofuel value chain about what the future of clean fuel incentives should look like. Some industry groups see a wholesale reversion to preexisting biofuel credits — or even a temporary period where various partly overlapping incentives coexist — as a tough sell to cost-concerned lawmakers and have instead pushed for revamping 45Z. A proposal last month backed by some farm groups would keep the 45Z incentive but ban foreign feedstocks and adjust carbon intensity modeling to benefit crops. Republicans could keep, modify, extend, or repeal the 45Z incentive as part of negotiations around a larger tax bill this year. But the caucus is still negotiating how much to reduce the federal budget deficit and what to do with Inflation Reduction Act incentives that have spurred clean energy projects in conservative districts. Uncertainty about the future of biofuel policy and sharply lower margins to start 2025 have led to a recently pronounced drop in biodiesel and renewable diesel production . President Donald Trump's administration is working on new biofuel blend mandates, which could be proposed in the coming weeks, but has said little about its plans for biofuel tax policy.
