A Large chunk of ethanol was transported via rail in US

The Energy Information Administration reports fuel ethanol is second only to coal as the most-transported fuel by rail. According to its Petroleum Supply Monthly, 95% of all US fuel ethanol deliveries between regions in the first half of 2022 were by rail. The majority of the US capacity to produce fuel ethanol (94%) is in the Midwest; however, most fuel ethanol is consumed in other regions.

In the first half of 2022, nearly all of the fuel ethanol that was delivered by rail (97%) originated in the Midwest. Rail accounted for 96% of the Midwest’s fuel ethanol deliveries to the East Coast and 90% of deliveries to the Gulf Coast. All fuel ethanol deliveries to the Rocky Mountain and West Coast regions were transported from the Midwest by rail. These percentages have held relatively steady since 2010, the earliest data on record.
