Ethanol industry groups are intensifying efforts to ensure renewable fuels are included in emerging international maritime fuel policies, arguing the shipping sector could become a major new source of demand for U.S. agriculture. The push comes as the International Maritime Organization and national governments consider policies aimed at reducing greenhouse gas emissions from ocean-going vessels. Ethanol advocates say the fuel offers a lower-carbon alternative that can be used in many methanol-capable ship engines without significant modifications. The Renewable Fuels Association and other members of the American Biofuels Maritime Initiative are urging policymakers to adopt technology-neutral regulations that allow ethanol to compete alongside other alternative fuels. According to the coalition, expanding marine fuel markets could support U.S. corn growers and rural economies. Interest in ethanol as a marine fuel is growing among global shipping companies. Reuters reported that firms including Maersk and Vale have conducted trials or commissioned vessels capable of operating on ethanol-based fuels as they seek to reduce emissions and diversify fuel supplies. Industry estimates cited by the Renewable Fuels Association suggest capturing just 5% of the global marine fuel market could increase annual ethanol demand by 4 billion to 5 billion gallons and boost corn demand by roughly 1.5 billion bushels. Supporters say policy decisions made over the next several years will help determine whether ethanol becomes a significant player in the maritime fuel market.
