In 2023, the Iowa Renewable Fuels Association (IRFA) reported a historic milestone in ethanol production, with Iowa's output reaching an unprecedented 4.6 billion gallons, surpassing the previous record of 4.5 billion gallons achieved in 2022. This remarkable increase underscores the resilience and dynamism of Iowa's ethanol industry, particularly given the relatively stable demand for ethanol observed in recent years. The ability of Iowa ethanol producers to elevate production levels once again reflects their dedication to innovation and operational efficiency, as well as the robust support from Iowa corn growers.

The sustained growth in ethanol production bodes well for the industry's future prospects. To capitalize on this momentum and facilitate further expansion in the short term, stakeholders are advocating for the swift finalization of year-round E15, which would unlock additional avenues for growth and market penetration. Moreover, there exists a promising opportunity to tap into a burgeoning market segment: sustainable aviation fuel. The adoption of sustainable aviation fuel could catalyze substantial biofuels growth over the next three decades, offering a pathway towards greater sustainability and reduced carbon emissions.

In contrast to the notable uptick in ethanol production, Iowa's biodiesel sector experienced stability in 2023, with production remaining consistent at 350 million gallons, a figure nearly identical to the 349 million gallons produced in the preceding year. This steady performance is indicative of the maturity and resilience of Iowa's biodiesel industry, which has adeptly navigated market fluctuations and regulatory changes. The sustained production levels also reflect the broader expansion of soybean crush capacity, both nationally and within Iowa, with soybean oil comprising 77 percent of the feedstock for biodiesel production in the state.

The data compiled by the IRFA, drawing from industry surveys, public reports, and other reputable sources, provides valuable insights into the state of Iowa's renewable fuels sector. As the leading advocate for the state's liquid renewable fuels industry, the IRFA plays a pivotal role in fostering its growth and development. Iowa stands at the forefront of renewable fuels production in the United States, boasting ethanol refineries with an annual production capacity exceeding billions of gallons, alongside biodiesel facilities capable of producing over 400 million gallons annually.

With Iowa contributing approximately 30 percent of the total U.S. ethanol production in 2023, the state occupies a central position in the nation's renewable fuels landscape. The substantial increase in annual ethanol production capacity, which now stands at approximately 4.7 billion gallons in Iowa alone, underscores the industry's potential for further expansion and advancement. However, the realization of this growth potential hinges on the alignment of market dynamics, regulatory frameworks, and technological advancements to meet evolving consumer demands and sustainability imperatives.
