Feedstock imports shake up US biofuel production

Feedstock imports shake up US biofuel production

New York, 24 July (Argus) — Waste from around the world is increasingly being diverted to the US for biofuel production, helping decarbonize hard-to-electrify sectors like trucking and aviation. But as refiners turn away from conventional crop-based feedstocks, farm groups fear missing out on the biofuels boom. Driven by low-carbon fuel standards (LCFS) in states like California, US renewable diesel production capacity has more than doubled over the last two years to hit a record high of 4.1bn USG/yr in April according to the Energy Information Administration. Soybean and canola processors have invested in expanding crush capacity, expecting future biofuels growth to lift vegetable oil demand. But policymakers' growing focus on carbon intensity, a departure from the long-running federal renewable fuel standard (RFS) that sets volume mandates for broad types of fuel, primarily benefits waste feedstocks, which generate larger LCFS credits because they are assessed as producing fewer emissions. Argonne National Laboratory's GREET emissions model, which has been modified by federal and California regulators for clean fuels programs, factors in emissions sources like fertilizers and diesel use on farms for virgin vegetable oils but not for used oils sourced from cooking operations. Refiners trying to maximize government subsidies are thus sourcing waste-based feedstocks from wherever they can find them. Through May this year, imports to the US under the tariff code that includes used cooking oil (UCO) and yellow grease rose 90pc from year-prior levels to more than 1.8bn lb (844,000t). While China represents most of that, sources are diverse, with significant sums coming from Canada, the UK, and Indonesia. Imports of inedible and technical tallow, waste beef fat that can be turned into biofuels, have also risen 50pc so far this year to 800,000lb on ample supply from Brazil. While soybean oil was responsible for nearly half of biomass-based diesel production in 2021, that share has declined to around a third over the first four months this year as imports surge (see graph). "Every pound of imported feedstock that comes in displaces one pound of domestically sourced soybean oil or five pounds of soybeans," said Kailee Tkacz Buller, chief executive of the National Oilseed Processors Association. Even as LCFS and RFS credit prices have fallen over the last year, hurting biofuel production margins and threatening capacity additions , imports have not slowed. Feedstock suppliers, many from countries with less mature biofuel incentives and limited biorefining capacity, might have few options domestically. And exporting to the US means they can avoid the EU's more prescriptive feedstock limits and mounting scrutiny of biofuel imports. More ambitious targets in future years, particularly for sustainable aviation fuel, "will create a lot of competition for UCO in the global market," said Jane O'Malley, a researcher at the International Council on Clean Transportation. But for now, "the US has created the most lucrative market for waste-based biofuel pathways." Incentives for US refiners to use waste-based feedstocks will only become stronger next year when expiring tax credits are replaced by the Inflation Reduction Act's 45Z credit, structured as a sliding scale so that fuels generate more of a subsidy as they produce fewer greenhouse gas emissions. While essentially all fuel will receive less of a benefit than in past years since the maximum credit is reserved for carbon-neutral fuels, the drop in benefits will be most pronounced for fuels from vegetable oils. Granted, President Joe Biden's administration wants the 45Z credit to account for the benefits of "climate-smart" agriculture, potentially helping close some of the assessed emissions gap between crop and waste feedstocks. But the administration's timeline for issuing guidance is unclear, leaving the market with little clarity about which practices farmers should start deploying and documenting. "While a tax credit can be retroactive, you can't retroactively farm," said Alexa Combelic, director of government affairs at the American Soybean Association. Squeaky wheel gets the soybean oil The concerns of agricultural groups have not gone unnoticed in Washington, DC, where lawmakers from both parties have recently called for higher biofuel blending obligations, prompt 45Z guidance, and more transparency around how federal agencies scrutinize UCO imports. There are also lobbying opportunities in California, where regulators are weighing LCFS updates ahead of a planned hearing in November. At minimum, agricultural groups are likely to continue pushing for more visibility into the UCO supply chain, which could take the form of upping already-burdensome recordkeeping requirements for clean fuels incentives and setting a larger role for auditors. Fraud would be hard to prove, but two external groups told Argus that the Biden administration has indicated that it is looking into UCO collection rates in some countries, which could at least point to potential discrepancies with expected supply. More muscular interventions, including trade disincentives, are also possible. Multiple farm associations, including corn interests frustrated that the country's first alcohol-to-jet facility is using Brazilian sugarcane ethanol , have asked the Biden administration to prevent fuels derived from foreign feedstocks from qualifying for 45Z. The possible return of former president Donald Trump to the White House next year would likely mean sharply higher tariffs on China too, potentially stemming the flow of feedstocks from that country — if not from the many others shipping waste-based feedstocks to the US. Protectionism has obvious risks, since leaving refiners with fewer feedstock options could jeopardize planned biofuel capacity additions that ultimately benefit farmers. But at least some US agriculture companies, insistent that they can sustainably increase feedstock production if incentives allow, see major changes to current policy as necessary.
