DNV GL paper suggests near-term success for LNG in shipping; alternative fuel mix to diversify over time

Green Car Congress

DNV GL is studying a number of alternative fuels or energy carriers that are already used or could be potentially used in shipping in the future. LNG bunkering for ships is currently only available in a number of places in Europe, Incheon (Korea) and Buenos Aires (Argentina) but the world’s bunkering grid is developing.
