In this report, ICCT describe trends in global ship activity and emissions for the years 2013 to 2015. ICCT found that emissions generally increased over this period, with efficiency improvements more than offset by increases in activity.
Although none of the ZEVs are estimated to be more competitive than conventional shipping by 2030, the technology options are evolving rapidly and it’s possible that over the next 10 years the gap could reduce even further than this study estimates. If this gap does not close then there may be a need for regulatory intervention in the near future, to drive the viability compared to conventional fossil fuels.
This new report assesses seven technology options for ZEVs, applied to five different case study ship types across three different regulatory and economic scenarios. These options consist of various combinations of battery, synthetic fuels and biofuel for the onboard storage of energy, coupled with either a fuel cell and motor, internal combustion engine; or a motor for the conversion of that energy store into the mechanical and electrical energy required for propulsion and auxiliary services.
Zero Emission Vessels 2030 is the latest in LR’s series of reports looking at fuel and technology trends for the marine industry, aimed at developing new knowledge and tools that can contribute to policy debate. Previous reports include Global Marine Trends 2030, Global Marine Fuel Trends 2030 and Global Marine Technology Trends 2030 and Low Carbon Pathways 2050.
