Many technologies are being considered to reduce carbon emissions from shipping. The American Bureau of Shipping (ABS) publication Setting the Course to Low Carbon Shipping: Pathways to Sustainable Shipping has categorized the available maritime fuel options for decarbonization. Among them, hydrogen (liquefied LH2 , or gaseous H2 ) was identified as a low- to zero-carbon fuel that can help meet the IMO GHG reduction target for 2050. Hydrogen offers ship owners and operators a low-carbon and low-emission fuel option for potential use in internal combustion engines and fuel cells.
Through a series of sustainability whitepaper publications, ABS is providing additional information to highlight the fuels being considered by the marine industry to meet the IMO GHG goals. This whitepaper provides information for the consideration of hydrogen as marine fuel in both the near-term and long-term.
