US railroads are preparing for a rise in ethanol shipments as the Section 45Z Clean Fuel Production Credit reshapes the biofuels market. Ethanol producers are adjusting operations to qualify for the incentive, which rewards lower carbon intensity through energy efficiency, carbon capture, or renewable power sourcing. Since ethanol cannot be shipped through petroleum pipelines due to its hygroscopic and solvent properties, rail remains the primary long-haul option, moving 60 to 70 percent of all US ethanol. Short-line and regional railroads are critical for first-mile and last-mile service to rural plants. As producers scale up or shift output to qualify for the credit, rail infrastructure and equipment investments will be key to connecting Midwest production hubs with coastal blending centers and export markets. The article also notes that rail's inherent fuel efficiency aligns with the low-carbon goals of the clean fuel economy.
