E15 Sales Set Another Record in MN

Cindy Zimmerman Leave a Comment

Sales of 15 percent ethanol blended fuel, known as E15 or Unleaded 88, set another record in Minnesota last year.

The final report for 2025 out from the Minnesota Department of Commerce last week showed a one percent increase in Unleaded 88/E15 sales in 2025, totaling 144.34 million gallons compared to 142.89 million gallons in 2024. Last year was the fourth straight year annual sales in the state exceeded 100 million gallons.

“The record sales of Unleaded 88 in Minnesota over the last five years show that despite regulatory uncertainty from Washington, D.C., retailers continue to expand access and consumers continue to fill up with E15. That’s because it works in any car 2001 and newer and saves drivers between $0.15 and $0.30 per gallon. As the ‘E15 Rural Domestic Energy Council’ continues to consider a framework for passing year-round E15, we urge them to listen to consumers who are clearly demanding permanent access to a better fuel at a better price,” said Brian Werner, executive director of the Minnesota Bio-Fuels Association.

According to MN Biofuels, Unleaded 88 is now available at 552 stations in the state. BP became the latest brand to offer Unleaded 88 in Minnesota last year, joining Amoco, ARCO, Casey’s, Cenex, Holiday, Hy-Vee, Kwik Trip, Little Dukes, Love’s, Marathon, Minnoco and Speedway.

EPA and USDA Officials to Speak at NEC

Cindy Zimmerman Leave a Comment

The Renewable Fuels Association has announced key officials with the U.S. Department of Agriculture and Environmental Protection Agency will be speaking at the upcoming National Ethanol Conference Feb. 24-26 in Orlando.

On Wednesday, Feb. 25, attendees will hear from Aaron Szabo, assistant administrator of the U.S. Environmental Protection Agency’s Office of Air and Radiation. This office oversees implementation of Clean Air Act programs, including the Renewable Fuel Standard. Szabo is expected to address the work of the Trump administration on ethanol, including EPA’s proposal creating the highest-ever renewable volume obligations under the RFS, the issuance of emergency waivers allowing year-round sale of E15, and the agency’s swift efforts to reform vehicle tailpipe GHG standards and remove the federal EV mandate.

The following day, Daniel Whitley, administrator of the Foreign Agricultural Service, will provide an update on global trade policy issues affecting the ethanol industry at a time when we are seeing record exports of ethanol—more than 2 billion gallons in 2025. As the Trump administration has focused on new trade agreements around the world, expanding ethanol exports has been a priority in many of them.

An historic alignment of agreement between the oil and ethanol industries is being held hostage by a small number of refiners, threatening the future of nationwide, year-round E15 (15% ethanol fuel).

Nebraska Ethanol Board chairman Jan tenBensel shared a graphic on social media last week calling out six refining companies by name with a combined revenue of nearly $172 billion. “The handful of refining companies trying to kill the year-round E15 bill make more money than all of our nation’s farmers and ranchers combined! Yet, they say they need RFS “hardship exemptions” to avoid blending ethanol and biodiesel? Give me a break!,” tenBensel said on X.

The companies named are Tennessee-based Delek US, HF Sinclair, Canadian companies Cenovus Energy and Suncor Energy, CVR Energy in Texas, and Houston-based Par Pacific.

The impact the refinery hold-outs could have on the push to get E15 legislation completed this month in Congress was discussed at last week’s Iowa Renewable Fuels Summit.

“I think this is a story of more than 95% of the liquid fuel supply chain on one side and six billion dollar companies masquerading as small refiners on the other side. And I think that retailers are firmly on the right side of that,” said Matt Durand, Deputy Legal Counsel, National Association of Convenience Stores.

Troy Bredenkamp, Senior Vice President of Government & Public Affairs for the Renewable Fuels Association, said the support for E15 is significant, but the retailers who are opposed are powerful. “We have probably 100% of the ag community in support or neutral. We have 100% of the retail segment in support or neutral, certainly the biofuel segment in support,” he said. “So you really have these outlying midstream refineries, publicly traded mostly, some of them are foreign-owned, that are the losers in the new deal. When you’re talking about shrinking the size of the small refining sector from 37 facilities down to 17, there’s losers in that group.”

Bredenkamp says there are about 20 refineries in total, with the six named mid-size refineries owning multiple facilities. “So there’s a windfall that they’re going to be out of if they don’t continue to get small refinery exemptions. The 5 or 6 in that category have friends in high places. And so those are the ones that we’re up against.”

E15 Deadline Coincides with Ethanol Conference

Cindy Zimmerman Leave a Comment

The National Ethanol Conference is coming up February 24-26 in Orlando, coinciding this year with an important deadline facing the recently formed E15 Rural Domestic Energy Council, which has been having meetings over the past week in Washington D.C.

The council is tasked with submitting a legislative proposal by February 15 with the goal of considering the bill by February 25. Renewable Fuels Association President and CEO Geoff Cooper says that will make the NEC interesting. “The whole focus of our event this year is on unleashing American ethanol, unleashing new opportunities for corn growers, and unfortunately the pathway to doing that often runs through Washington DC or through state capitols,” said Cooper. “So we will have a heavy focus on what are those solutions for unleashing greater ethanol demand, greater demand for corn, greater value for both commodities, and E15 is a big part of that.”

Other topics to be addressed at NEC 2026 include energy, ag, and tax policy issues; the impact of AI in the ethanol marketplace, global demand for ethanol, maritime markets, 45Z tax credit opportunities, and updates from USDA and EPA.

Winter Weather Impacts Ethanol Production

Cindy Zimmerman

Ethanol production plunged along with the temperatures across the country last week, according to the latest EIA data analyzed by the Renewable Fuels Association for the week ending January 30.

Ethanol production dropped 14.2% to 956,000 b/d, equivalent to 40.15 million gallons daily and the lowest weekly volume since mid-April 2024, reflecting the effects of the winter storm. Output was 14.0% lower than the same week last year and 8.8% below the three-year average for the week. The four-week average ethanol production rate declined 3.2% to 1.10 million b/d, equivalent to an annualized rate of 16.85 billion gallons (bg).

Ethanol stocks decreased 1.0% to 25.1 million barrels. Stocks were 4.8% less than the same week last year and 0.3% below the three-year average.

Refiner/blender net inputs of ethanol fell 10.4% to 791,000 b/d, equivalent to 12.16 bg annualized. Ethanol exports expanded 37.6% to an estimated 216,000 b/d (9.1 million gallons/day).

Former Industry Leaders Warn of Farm Crisis

Cindy Zimmerman

A bipartisan group of former leaders of America’s major agricultural commodity associations and biofuels organizations, farmer leaders, and former senior USDA officials, sent a letter to Congress this week sounding the alarm about the current state of the farm economy and the potential for “widespread collapse of American agriculture.”

In a letter released today to the leadership of the House and Senate Agriculture Committees, twenty-seven former agricultural executives and officials with decades of experience detailed how current Administration policies have harmed the farm economy and the need to take substantial action. The signatories include past presidents and CEOs of the American Soybean Association, National Corn Growers Association, National Pork Producers Council, National Barley Growers Association, National Milk Producers Federation, US Grains Council, and Renewable Fuels Association, past Directors of the Illinois and Nebraska Departments of Agriculture, and other farm leaders and senior agricultural policy experts.

Among the letter signatories are former presidents of NCGA Harold Wolfe and Pam Johnson, past NCGA CEO Jon Doggett, former RFA chair Randy Doyal, and past RFA CEO Bob Dinneen.

“First and foremost, what we want to do is to start a conversation,” said Dinneen. “Let’s focus on the solutions. We outline what we think some of them might be, but we don’t have all the answers. Let’s figure that out. The bottom line is we’re in a perilous state, and we say that without hyperbole or exaggeration. It is perilous. We need to figure it out.”

Dinneen says the group offered nine actions that can be taken to help restore the farm economy. “Let’s end the tariffs on farm inputs. Let’s try to open up markets elsewhere. Let’s stop some of the chaotic trade policies that are out there. But there’s more than that. We think even on biofuels, there are things that can be done, and Congress has been irresponsible in not addressing the things that they could be doing to increase biofuel demand. Let’s get E15 year-round done once and for all.”

The former RFA executive says the creation of a Rural Domestic Energy Council instead of passing legislation is an insult. “You don’t need a council. You need legislative action. You need a backbone,” said Dinneen. “The failure of Congress to get year-round E15 done has really hampered the expansion of the Renewable Fuel Standard because EPA is reluctant to move beyond 15 billion gallons of corn derived ethanol without there being a place to put that. And as automobiles are becoming more fuel efficient and needing less fuel on a yearly basis, the need to grow that market and get more ethanol into each gallon so that you can break through that blend wall has been more and more critical. So E15 is important to allow the renewable fuel standard to do what it was supposed to do, and that is to drive increased demand for fuel ethanol.”

Treasury Releases Proposed 45Z Regulation

Cindy Zimmerman

The Department of the Treasury and the Internal Revenue Service today issued proposed regulations for domestic producers of clean transportation fuel to determine their eligibility for and calculate the clean fuel production credit, often referred to as the 45Z credit, as modified under the One, Big, Beautiful Bill. The clean fuel production credit provides businesses an income tax credit for clean transportation fuel produced domestically after Dec. 31, 2024, and sold by Dec. 31, 2029.

Today’s guidance also proposes rules to implement certain OBBB changes to the clean fuel production credit. OBBB changed the clean fuel production credit to:
Extend the credit to Dec. 31, 2029;
Limit feedstocks to those grown or produced in the US, Mexico, or Canada;
Add prohibited foreign entity restrictions;
Broaden sale attribution for fuel sold through related intermediaries;
Eliminate the special rate for sustainable aviation fuel;
Add an anti-abuse provision to prevent double crediting;
Prohibit negative emissions rates except for fuels derived from animal manure;
Require feedstock-specific emissions rates for fuels derived from animal manure; and
Exclude indirect land use changes from emissions rates.

Renewable Fuels Association President and CEO Geoff Cooper says the proposed rule is a step in the right direction. “The proposal appears to resolve some of the previous confusion around what constitutes a ‘qualified sale,’ and begins to integrate the important improvements to 45Z that resulted from the One Big Beautiful Bill Act, such as the removal of indirect land use change emissions from the carbon intensity scoring framework.

“However, much work remains to be done and many questions still need to be answered. First and foremost, ethanol producers are anxiously awaiting a new, revised version of the 45ZCF-GREET model, which will help shed light and provide clearer direction on several critical issues. In addition, questions remain to be resolved around the quantification of emissions related to low-carbon feedstock production at the farm level, implementation of foreign feedstock prohibitions, and provisions related to the use of energy attribute credits.”

Cooper said RFA looks forward to providing comments on the proposal to the Treasury Department and intends to testify at an upcoming hearing on the rule.

American Coalition for Ethanol (ACE) CEO Brian Jennings would like to see additional clarity on how ethanol producers can monetize low-carbon farming practices through the tax credit.

“We urge Treasury to continue working closely with the U.S. Department of Agriculture and the Department of Energy to develop and finalize the tools necessary to achieve full monetization of farming practices, such as USDA’s Feedstock Carbon Intensity Calculator (FD-CIC) and DOE’s 45ZCF-GREET model,” said Jennings. “Last year, USDA asked ACE to help peer-review and beta-test the FD-CIC, and we submitted reams of data and feedback on the tool. We are encouraged Treasury expects the 45ZCF FD-CIC to undergo periodic updates, including incorporation of new data gathered from real-world activities such as the USDA Regional Conservation Partnership Program (RCPP) activity being led by ACE. This work is specifically designed to address the perceived need for more empirical data on the low-carbon benefits of farming practices to help improve the accuracy of modeling tools. We are hopeful the FD-CIC and 45ZCF-GREET model will reflect the feedback we provided and are finalized soon.”

Written or electronic comments will be accepted for the next 60 days and a public hearing has been scheduled for May 28.

What is E15?

Cindy Zimmerman

When President Trump was in Iowa last week and spoke about E15, there were many on social media who asked the question, “What is E15 and why is the president talking about it?”

“I promised to support E15 all year round… I am trusting speaker Mike Johnson and Leader John Thune to find a deal that works for farmers, consumers, and refiners, including small and mid-sized refiners, to get E15 approved and they’re working on it and they’re very close to getting it done,” said Trump, during remarks in Clive, Iowa.

The fact is that very few people actually have any clue about E15, and the few who do know what it is, even within the industry, do not understand the issue that has been plaguing it for over a decade – mainly because it is very technical and makes absolutely no sense. It is an issue that cannot be explained in a simple sound bite. Simply saying that we need year-round, nationwide E15 does nothing to explain the issue, especially since retailers have been able to sell E15 during the summer months for the past several years, thanks to waivers.

So, what is the issue? E15 was first approved for use in new vehicles by the EPA in 2010, extended to 2001 and newer vehicles in 2011. This was granted by a partial waiver under the Clean Air Act. However, also under the Clean Air Act, gasoline sold during the summer ozone season (generally June 1–September 15) must meet lower Reid Vapor Pressure (RVP) standards to reduce evaporative emissions (a contributor to smog). E15 typically has a higher RVP than E10 and therefore doesn’t automatically qualify for the summer gasoline waiver that E10 enjoys — meaning E15 normally cannot be sold in most of the U.S. during summer.

That is the problem. Up until 2019, summer sales of E15 were prohibited in those regions with RVP volatility limits. In 2019, President Trump tried to fix the problem by having his first term’s EPA issue a regulatory action to extend the 1-psi RVP waiver to E15 during the summer season.

However, industry litigation led a federal court to determine the agency’s interpretation exceeded the authority in the Clean Air Act. As a result, the seasonal RVP restriction remained in effect in most parts of the country even after that 2019 rule. Since 2022, under President Biden, summer sales of E15 have been allowed by emergency waivers.

The first emergency fuel waivers specifically for summer E15 were issued under CAA Section 211(c)(4)(C) citing “extreme and unusual” fuel supply circumstances in April 2022 under the Biden EPA. These temporary (up to 20-day) waivers have been renewed multiple times each summer since then (2022, 2023, 2024, and 2025 under the Trump EPA), effectively allowing continued nationwide summer sales on a stopgap basis.

The summer restriction on E15 is basically a statutory problem baked into the Clean Air Act (CAA) which sets the Reid Vapor Pressure (RVP) limits for gasoline sold during the summer ozone season (June 1–Sept. 15). Congress wrote a specific 1-psi RVP waiver into the law only for gasoline containing exactly 10% ethanol (E10). That is why Congress is the only pathway for a final fix to the problem because only Congress can amend the Clean Air Act and explicitly extend the 1-psi RVP waiver to E15
or create a new ethanol-neutral standard tied to emissions, not blend level.

Now the question is, what are the chances that this newly-formed E15 Rural Domestic Energy Council can get that done and passed by the end of this month? If I were a betting person, I would not put my money on it.
