Climate-neutral industrial alcohol made with renewable electricity appears to be the most suitable synthetic fuel to decarbonise international shipping, researchers from the Institute of Maritime Energy Systems at the German Aerospace Centre (DLR) have found. Switching to green methanol could reduce CO2 emissions by 96 percent over the entire life cycle of ships, the researchers said in a report commissioned by NGO Greenpeace.
