Geoff CooperPresident & CEO AN EXTRAORDINARY FUEL Ethanol, or ethyl alcohol (C2H5OH),is a renewable fuel produced fromplants—organic materials containingstarches, sugars, or cellulosic matter.In the U.S., nearly all ethanol isprocessed by dry mills using fieldcorn not intended for humanconsumption via milling, cooking,enzymatic breakdown, fermentation,distillation, and dehydration.Ethanol used as a fuel sourcechecks several notable boxes: 4Renewable and sustainable4Reduces greenhouse gases4Boosts octane levels4Improves combustion efficiency4Supports energy independence4Stimulates rural economies4Offers savings to refiners and con-sumers A U.S. POWERHOUSE Global fuel ethanol production hit a record31.1 billiongallons in 2024. The United Statesremained the largest producer, accounting forover half of global output. Nearly200ethanol biorefineries across24states have acumulative total capacity of over18 billiongallons and anaverage per average plant capacity of92milliongallonsper year. Over halfof production capacity is installed in thelargest corn states of Iowa, Nebraska, and Illinois. FUELING THE ECONOMY In 2024, biorefineries processed 5.5 billion bushelsof corn worth roughly$23 billioninto$34.5 billionof ethanol and co-products. This50% boostmakesethanol the most important value-added market forU.S. corn. Ethanol’s Value-Added PropositionBased on average prices and product Based on average prices and product yields in 2024,a typical dry mill ethanol plant was adding approx-imately $2.06 of additional value—nearly 50%—toevery bushel of corn processed.yields in 2023, a typical dry mill ethanolplant was adding approximately$2.71 of additional value—a remarkable45%—to every bushel of corn processed. Corn Cost per Bushel Ethanol and the 2024 Economy Direct Jobs............................... 55,810Indirect/Induced Jobs............ 258,089Household Income.......... $28.3 BillionGDP Contribution............ $53.0 BillionTax Revenues................... $10.3 Billion The ethanol industry providesstable jobswithcom-petitive wagesin rural communities, offering valuableemployment opportunities where they are often scarce. FUEL AND FOOD The U.S. ethanol industry is among the largestsuppliers in the world of nutritious, high-proteinanimal feed. In 2024, ethanol biorefineries generated36 mmtof distillers grains and corn gluten feed and meal. On average,1 bushel of cornyields: 2.9 gallonsDenatured fuel ethanol14.5 poundsDistillers grains (10% moisture)0.9 poundsDistillers corn oil16.0 poundsCaptured biogenic CO2 DISTILLERS GRAINS CONSUMPTIONDistillers grainsare an important ingredient in animalfeed rations worldwide. BY SPECIES2024 DISTILLERS GRAINS CONSUMPTIONBY SPECIES Distillers corn oilis a key feedstock for biobaseddiesel and SAF. It is also an animal feed ingredient. High-purity CO2plays a vital role in the food andbeverage industry and serves a wide range ofessential industrial applications. HIGHER ETHANOL BLENDS EPA approves E15in100%of cars and light trucksbuilt over the past 25 years. Automakers endorse E15use in94%of vehicles sold in 2024. Over20 millionflex fuel vehicles (FFVs) on the roadtoday can use fuel blends with up to 85% ethanol. Still,automakers scaled back from 80 FFV models a fewyears ago to just a handful in 2025. In 2024, drivers choosingE85 pocketed74 centson every gallon versusregular gas. Expanded availability of E15 and higher level ethanolblends sustained the national average blend rate in2024 at nearly10.4%—well beyond the so-called“10% blend wall.” A GLOBAL MARKET Record 2024 U.S. ethanol exports represented12%of production and$4.2 billionin sales. Record-lowimported ethanol was recorded. Booming demand pulled37%of U.S. distillers grainsoutput into more than50countries. (12 mo. moving avg. through Oct.) THE POWER OF OCTANE WHERE’S THE BUZZ AROUND OCTANE? Automakers:Turbocharged, higher-compression engines thrive on high-octanegas to maximize performance. Consumers:Sales of premium (high-octane)fuel has seen exponential growth for thelast 15 years. Refiners:Sub-octane gasoline blendstockgets a boost from cost-effective octaneadditives, creating the 87 AKI fuel driversknow and love. Ethanol is thesafesthigh-octane fuel additiveavailable to refiners and blenders. Ethanol is also thelowest costadditive, so it helpslower prices at the pump. LET’S CLEAR THE AIR Ethanol is thebest tool availableto reduce tailpipeemissions of harmful pollutants. Adding ethanol to gasoline reduced 2024 transporta-tion sector GHGs by54.3 mmt.
