US ethanol readily available to fuel the world’s methanol- capable fleet

Study published by MEMA, a platform of the Global Centre for Green Fuels, finds ethanol can use existing methanol engines and bunkering infrastructure

US well-positioned to support maritime biofuel demand, with around 2 billion gallons a year of spare ethanol production capacity

SINGAPORE, 12 November 2026 – Ethanol can use the dual-fuel engines and bunkering infrastructure built for methanol with limited modification. That gives shipowners a readily available fuel for a growing fleet at a time when supply of low-emission methanol remains constrained, according to a new study published today by the Maritime Ethanol & Methanol Alliance (MEMA), a platform of the Global Centre for Green Fuels (GCGF).

According to the study, Marine Ethanol: Unlocking the US Opportunity, ethanol can support the more than 300 methanol-capable vessels in service or on order, either on its own or blended with methanol.
