Research on Validating the Future of Carbon Markets

Cindy Zimmerman Leave a Comment

Five years ago, the U.S. Department of Energy tapped the Daugherty Water for Food Global Institute (DWFI) to tackle the critical challenge of scientifically validating carbon sequestration in Midwest corn and soybean production. In a new Water for Food podcast, DWFI Director of Research Christopher Neale said the $3 million project at the intersection of energy, agriculture and policy is now in its final 120-day closeout phase.

“We’ve been working on measuring and modeling the whole carbon cycle in agricultural fields in the Midwest, specifically that produce grains for the ethanol industry,” said DWFI Director of Research Christopher Neale.

Neale says they studied fields that were representative of the acreage providing grain for the ethanol industry in different types of production systems. “So here in Nebraska, at Mead, one of our fields is an irrigated corn-soybean rotation, direct planting, … one’s in Iowa, which is rain-fed, but also corn-soybean, and it has cover crops…and then the third field was in Morris, Minnesota, also corn and soybeans, but in a different climate,” said Neale. “So what we’ve been doing is using the measurements in the models with all these other inputs to calculate how much carbon is sequestrated in a cornfield in a typical year, and then in soybeans and in the rotation of corn and soybeans.”

A new nationwide poll just released by the Renewable Fuels Association (RFA) shows a record 74 percent of registered voters support the Renewable Fuel Standard (RFS) today, with just 12 percent opposed to the policy first enacted in 2005 and expanded in 2007. This is the highest level of support for the RFS in 10 years of quarterly polling by RFA.

The poll, conducted by Morning Consult on behalf of RFA, surveyed more than 2,000 registered voters and also found that 87 percent believe it is important for America to be energy independent, and 80 percent said renewable fuels like ethanol are important to achieving energy independence.

“As Americans celebrate our nation’s independence this Fourth of July, these poll results send a clear message: voters recognize that American-made renewable fuels like ethanol strengthen our energy security, support domestic jobs, and help reduce our reliance on foreign energy,” said RFA President and CEO Geoff Cooper. “Record-high support for the Renewable Fuel Standard reflects a growing understanding that homegrown, affordable renewable fuels are essential to America’s energy future and economic strength.”

With the holiday weekend approaching and gas prices still high, the poll also found that 83 percent are concerned about gas price fluctuations, with 53 percent being very concerned, while 71 percent said rising gasoline prices are likely to influence their vote in the upcoming mid-term elections.

USDA Finalizes Regenerative Feedstock Rule

Cindy Zimmerman Leave a Comment

As President Donald Trump signed an Executive Order this week advancing regenerative agriculture, USDA Secretary Brooke Rollins announced a final Regenerative Feedstock Rule designed to help farmers voluntarily capture new value from regenerative agricultural practices through biofuel markets.

The Regenerative Feedstock Rule establishes a framework to connect regenerative agriculture practices to new markets within the biofuel supply chain for corn, soybeans, sorghum, and spring canola. These standards include:

Covered biofuel feedstock crops and participating entities throughout the supply chain;
Field-level quantification of crop-specific carbon intensity;
Mass balance chain-of-custody standards, including traceability and recordkeeping;
Auditing and verification requirements; and
Regenerative agriculture practice standards for covered feedstock crops.

USDA is also releasing an updated USDA Feedstock Carbon Intensity Calculator (USDA FD-CIC) to help producers quantify regenerative practices such as cover crops, and improved nutrient management, and conservation tillage—including no-till and reduced tillage. Producers can use the resulting reports when marketing eligible feedstocks to participating biofuel producers.

The new framework creates significant opportunities for America’s leading biofuel feedstock producers. American farmers currently produce approximately 6 billion bushels of corn used annually for ethanol production, with 68 percent of corn farmers already implementing at least one regenerative practice. Likewise, producers grow approximately 1.8 billion bushels of soybeans for biofuel production, while 70 percent of soybean farmers already utilize at least one regenerative practice. As participation grows, USDA expects the rule to expand premium market opportunities for producers across the country.

Biofueling Agriculture Podcast

Chuck Zimmerman Leave a Comment

ZimmCastAmerican agriculture is at a crossroads today, but biofuels could point the way to a brighter future, according to a recent study from S&P Global and commissioned by U.S. Farmers and Ranchers in Action (USFRA).

“Fueling Agriculture: Biofuels as the Catalyst,” finds that biofuels have the potential to restore long-term profitability to American farms and drive investment in rural communities; unlock demand for sustainable feedstocks, creating a market that rewards farmers for pioneering modern farm practices; and strengthen food, economic and energy security on a global scale. It could also help motivate the U.S. Senate to pass legislation allowing year-round, nationwide sales of E15 (15% ethanol-blended fuel).

In this episode of the ZimmCast, hear from USFRA CEO Kevin Burkum; USFRA vice chairman and Maryland farmer Chip Bowling; Kevin Lindemer, S&P Global Energy; Kelsey Barnes, USDA Senior Advisor for Rural Development and Biofuels; Sens. Chuck Grassley (R-IA) and Tina Smith (D-MN).

White House Includes E15 in Funding Request

Cindy Zimmerman Leave a Comment

Ethanol supporters were pleased to see the Trump administration include passage of legislation to allow year-round sales of E15 in its $87.6 billion supplemental spending request to “address urgent needs related to Operation Epic Fury (OEF), in addition to other critical needs such as…supporting hardworking American farmers.”

The supplemental request to Congress from Russel Vought, director of the Office of Management and Budget, includes an additional $11.1 billion to support American farmers with $10 billion in temporary economic assistance for row and specialty crops planted in crop year 2026. “Furthermore, the Administration requests additional authorities that it strongly supports. These authorities include .. an urgent and needed fix that codifies the permanent, year-round sale of E-15.”

Renewable Fuels Association President and CEO Geoff Cooper thanked President Trump for supporting the year-round availability of E15 in both of his terms in office. “We are very grateful for his continued leadership on this important issue,” said Cooper. “President Trump clearly recognizes that E15 helps Americans save money with each fill-up, while also strengthening the farm economy and bolstering U.S. energy security. He has called on Congress multiple times now to pass legislation that simply allows consumers to choose lower-cost E15 all year long. The House has heeded this call by passing year-round E15 legislation in May. Now it’s time for the Senate to move quickly and give Americans what they clearly want and need—relief at the pump.”

However, Senate Agriculture Committee Chairman John Boozman (R-AR) released a discussion draft of a new five-year farm bill this week that left out any provisions for nationwide year-round E15 sales that, while expected, was still disappointing to biofuels and agricultural interests. National Corn Growers Association (NCGA) President Jed Bower said, “While this Congress has few legislative days left, there is still a lengthy to-do list for agriculture, including action on the farm bill, securing Senate passage of year-round E15 and the renewal of the U.S.-Mexico-Canada Agreement. Corn growers from across the country will be in Washington, D.C., the week of July 13 to advocate directly with members of Congress on these priorities.”

RFA Helping Girl Scouts Learn Car Care

Cindy Zimmerman

Girl Scouts Senior Car Care Badge

The badges that Girl Scouts can earn today include such practical skills as car maintenance, and the Renewable Fuels Association has stepped up to help them learn about the value and importance of caring for their vehicles and choosing the right fuels through its partnership with the Philadelphia-based Girls Auto Clinic. The workshops will also include educational information on the importance of renewable fuels like ethanol.

“We’re happy to support this program to help ensure that the next generation of drivers understand their vehicles, the responsibility of caring for them, and being safe on the road,” said Robert White, RFA Senior Vice President for Industry Relations and Market Development. “Patrice Banks and her team at Girls Auto Clinic have continued to do great work in expanding automotive knowledge and confidence in women, and this new program is a perfect natural extension of their mission.”

RFA will sponsor a series of three Girl Scouts Car Care Workshops delivered by Girls Auto Clinic and the related Shecanic Foundation. This initiative will serve close to 100 girl scouts through hands-on, practical automotive education.

Through these workshops, scouts will gain practical, real-world automotive knowledge that most young drivers never receive before getting behind the wheel. Participants will learn how to check tire pressure and tread depth, interpret dashboard warning lights, perform basic fluid checks, and determine when a repair can be handled at home versus when a visit to a mechanic is warranted. Roadside safety and emergency preparedness are also covered. The program equips young drivers with the skills and confidence to handle the unexpected on the road.

Participating scouts will receive an unofficial special patch for participating that they can add to the back of their vests. Additionally, these workshops also fulfill the hands-on component of their official Car Care Badge journey, allowing scouts to apply what they are learning in a practical, safe, and supportive setting.

Chippewa Valley Ethanol Celebrates 30th Anniversary

Cindy Zimmerman

Chippewa Valley Ethanol Co. (CVEC) is celebrating its 30th anniversary today with an open house at its Benson, Minn. biorefinery.

CVEC began producing ethanol in 1996, founded by local corn producers and the local electric cooperative. Their vision sought out ways to add more value to the high quality corn they produced locally while stabilizing electricity rates. Starting with an annual capacity of 15 million gallons per year, CVEC has since expanded to 50 million gallons of capacity, and has attracted investment from more than 950 producers, elevators, and community members. In addition to producing fuel ethanol, CVEC is the parent company to Glacial Grain Spirits, which produces industrial and beverage grade alcohol, and CVEC is a founding owner of Renewable Products Marketing Group (RPMG), which currently markets approximately 2 billion gallons of ethanol and 2.2 million tons of distillers grains annually.

CVEC has been a member of the Renewable Fuels Association since 2001, with former general manager Bill Lee serving as RFA chairman in 2004 and 2005. General Manager Chad Friese currently sits on the RFA Board of Directors. “All of us at RFA are proud to join our friends at CVEC in celebrating this remarkable milestone,” said RFA President and CEO Geoff Cooper. “As the ethanol industry enters its next chapter, CVEC remains one of the most innovative, forward-looking companies in the business. We look forward to continuing our partnership with CVEC to build new markets and create new opportunities for ethanol producers and farmers alike.”

Wholesale E85 Prices Drop as Low as Eight Cents

Cindy Zimmerman

Retail prices for E85 are already a good deal compared to regular gas, but according to the Iowa Renewable Fuels Association (IowaRFA), wholesale prices for E85 are currently as low as eight cents per gallon, with the highest price listed at only one dollar, which makes it a huge deal for owners of flexible fuel vehicles (FFVs).

FFVs are designed to run on any fuel blend from no ethanol up to E85, which contains up to 85 percent ethanol. Wholesale prices do not include federal and state taxes, transportation costs, and markups for things like credit card fees, depreciation and retailer margins.

“As a trade association, we never tell anyone how to price a product at any point in the supply chain,” said Iowa RFA Executive Director Monte Shaw. “But the public data shows that E85 should be an amazing bargain for FFV owners right now. So, we do encourage all parts of the supply chain to pass along these savings to consumers.”

Only General Motors currently sells new FFVs but there are over 20 million FFVs on the road in the United States and there is renewed interest in conversion kits to make regular vehicles capable of using up to 85% ethanol-blended fuel.

According to E85Prices.com, the current national average price spread between E85 and regular gasoline (E10) is approximately 30%, or roughly $1.00–$1.26 per gallon less for E85. Some of the biggest price spreads now are being seen in Indiana, with the cheapest price per gallon for E85 at just 85 cents – or a price spread of 76 percent. California is at 62% with the lowest price at $1.99.

New Study Shows Benefits of Biofuels Expansion

Cindy Zimmerman

A new S&P Global Energy study released today shows how expanded biofuel markets are a catalyst for agriculture, revitalizing farm communities, stabilizing farm incomes, and providing both food and energy security.

Commissioned by U.S. Farmers and Ranchers in Action (USFRA), the research, titled “Fueling Agriculture: Biofuels as the Catalyst,” offers a detailed, evidence‑based assessment of agriculture’s future and presents a data-driven roadmap for sustainable growth.

“This research demonstrates that biofuels are not just an energy solution—they’re an economic engine that could transform farming’s future,” said Maryland farmer Chip Bowling, Vice Chair of USFRA. “New evidence offered by highly respected experts at S&P Global Energy show that biofuels can unlock agriculture’s potential to provide abundant and affordable food, feed and fuel.”

USFRA held a press conference to announce the findings of the report, with comments from Bowling, as well as CEO Kevin Burkum, Sens. Chuck Grassley (R-IA) and Tina Smith (D-MN), and Kelsey Barnes, USDA Senior Advisor for Rural Development and Biofuels.

Sen. Grassley said the findings show the importance of year-round, nationwide E15. “The report that you are releasing will help grow momentum to get E-15 through the Senate and through the President’s desk. Enacting E-15 is a perfect way to celebrate America’s 250th years of freedom,” said Grassley.

Going off his prepared remarks, the senior senator from Iowa blasted those who came out against the E15 legislation passed by the House despite never being opposed in the past. “We have never heard anything from small refineries. And we never heard from the American Soybean Association that they didn’t like certain things in it,” Grassley said, expressing frustration at the limited time frame left this year to get a vote in the Senate. “But we got to move, and it’s almost too late now if we don’t get some action. So anything you can do to help, and this report is going to help, I’m going to say God bless you.”

Under an optimized high-growth scenario, the study projects global biofuel production, driven by agricultural innovation, could triple by 2050, expanding renewable fuels to capture a significantly larger share of the approximately 940-billion-gallon global liquid fuel market – including marine and aviation fuels.

Kevin Lindemer with S&P Global Energy says the study showed E15 is important for increasing corn demand. “By 2050, E15 would represent about six million (more) acres of corn,” said Lindemer. However, declining oil demand means that will still fall short.

At the same time, technology and innovation advances could dramatically increase ethanol production in the same time period. “We could go from the current level of about 35 billion gallons worldwide up to 140 billion gallons by 2050…if supply could create demand.”
