Key Points:
- The Environmental Protection Agency wants biofuel companies to produce 5.4 billion gallons of renewable fuel in 2026.
- Biodiesel producers must increase their overall output by more than 60% this year to hit these new government targets.
- Fuel prices continue to surge across the country as the ongoing U.S.-Israeli war on Iran disrupts global energy markets.
- Analysts warn that falling short of the blending quotas will force refiners to buy expensive credits and raise gas station prices.
The U.S. biodiesel industry faces a massive challenge this year. After suffering through a very difficult period, fuel producers must now ramp up their operations faster than ever before. The Environmental Protection Agency recently released its most ambitious biofuel blending mandates in history. Companies that turn soybeans into fuel must boost their production by more than 60% this year just to meet these new rules. Many industry experts seriously doubt these plants can work fast enough, and failing to hit the mark could push consumer diesel prices even higher.
Rising fuel prices during the U.S.-Israeli war on Iran pushed the EPA to set these aggressive targets in late March. The agency ordered companies to produce 5.4 billion gallons of biodiesel and renewable diesel for 2026. The government wants that number to hit 5.7 billion gallons in 2027. These new requirements represent a massive jump from the 3.35 billion gallons the industry produced last year. In reality, the EPA estimates the country actually needs a total supply of 6.07 billion gallons this year to satisfy the rules, because companies export some fuel and lose out on domestic compliance credits.
Politics plays a major role in these new government demands. Farmers and large agricultural groups spent years lobbying Washington for higher biofuel mandates. Last year, U.S. soybean prices crashed hard. China stopped buying American crops and switched to Latin American suppliers to avoid heavy trade tariffs imposed by President Donald Trump. Farmers represent a highly valued political base for Trump and the Republican Party. Politicians want to keep this group happy as they fight to protect their thin majorities in Congress during the November midterm elections.
The Renewable Fuel Standard forces oil refiners to blend billions of gallons of biofuels into the national fuel supply every single year. If a refiner cannot blend enough fuel, the company must purchase special compliance credits called RINs from other successful producers. If the entire industry fails to reach the blending targets, refiners must dip into their old savings accounts to use previously generated credits. Relying on this old bank of credits raises the overall cost of doing business. Those higher compliance costs eventually trickle right down to regular drivers at the gas pump.
Scott Irwin works as an agricultural economist at the University of Illinois and closely studies the biofuel market. He estimates that companies must generate exactly 915 million new credits each month to meet the new EPA mandates. The latest agency data, as of April 16, show that biodiesel blending generated only 651 million credits in March. While this marked a significant improvement over the 481 million credits generated in February, it still falls far short of the final goal. Irwin plainly states that the industry is nowhere near the required numbers and predicts massive deficits heading into 2027.
Government analysts also see a major shortfall coming soon. The U.S. Energy Information Administration recently published its latest forecast. The agency expects the country to supply about 1.52 billion gallons of traditional biodiesel and 3.53 billion gallons of renewable diesel in 2026. When you add those two numbers together, the total combined supply falls well below the strict requirement set by the EPA for the year.
Industry leaders admit they are scrambling right now to increase their daily output wherever possible. Paul Winters serves as the director of public affairs at the Clean Fuels Alliance of America. He says biofuel producers are deeply concerned about how they will comply with these new rules. Winters notes that coordinating massive supplies of raw materials and shipping the final fuel to the market always creates tough logistical challenges. Oil refiners agree with this assessment, stating that domestic supplies of raw materials simply cannot support the massive new EPA targets.
Weak demand in previous years forced many biofuel companies to shut down their plants or operate at very low capacity. Today, the biggest challenge involves waking these dormant factories up and pushing them to maximum capacity. Iowa produces more than 23% of all U.S. biodiesel. Monte Shaw leads the Iowa Renewable Fuels Association. He reports that idle plants across his state are spinning up as fast as possible following the EPA announcement. However, he warns that hitting Iowa’s combined annual goal of 400 million barrels will prove difficult until the Trump administration clearly explains a new clean fuel credit program called 45Z.
Farther north, Minnesota Soybean Processors decided to act quickly. The company restarted its idle Brewster plant less than one week after the EPA announced the new targets. General manager Jeramie Weller says the sudden surge in market demand sent a strong signal to the industry. His facility plans to produce 35 million gallons of fuel this year, a solid jump from the 25 million gallons it produced in 2025.
Processors claim they can run at full capacity if the government gives them enough time. However, building brand new plants remains a major headache. High tariffs on steel and aluminum make construction materials incredibly expensive, while a tight labor market makes it hard to find enough workers. On paper, the U.S. had 1.96 billion gallons of operable biodiesel capacity and 4.89 billion gallons of renewable diesel capacity sitting ready on January 1, 2026. This combined capacity should easily meet the 2026 quotas. Unfortunately, actual production in 2025 only reached 2.9 billion gallons, proving that running a plant at 100% efficiency is much harder in real life.
While soybean supplies look plentiful right now, market traders expect those raw materials to dry up significantly by the fourth quarter as more fuel plants come online. Winters summarized the brutal reality facing his industry. He says every single plant must run at 85% to 90% capacity year-round just to meet the current numbers. Beyond that, companies will absolutely need to build entirely new factories to meet the even higher mandates awaiting them in 2027.
