Decarbonization in Shipping Industry: A Review of Research, Technology Development, and Innovation Proposals

This review paper examines the possible pathways and technologies available that will help shipping sector achieve International Maritime Organization’s (IMO) deep decarbonization targets by 2050. There has been increased interest from important stakeholders regarding decarbonization, evidenced market surveys conducted Shell Deloitte. However, require financial incentives policies at an international regional level given maritime sector’s ~3% contribution to green house gas (GHG) emissions. The paper, based on research articles grey literature, discusses technoeconomic problems and/or benefits for IMO’s targets. presents a discussion recent literature alternative fuels (nuclear, hydrogen, ammonia, methanol), renewable energy sources (biofuels, wind, solar), maturity of (fuel cells, internal combustion engines) as well technical operational strategies reduce fuel consumption new existing ships (slow steaming, cleaning coating, waste heat recovery, hull propeller design). 2050 be achieved via radical technology shift together with aid social pressure, incentives, regulatory legislative reforms local, level.
