Vessel Emission Reduction Technologies & Solutions

Published — August 29, 2022

Based on work completed as part of a Center working group consisting of Center partners and external participants and contributors, the impact and role of vessel greenhouse gas and air pollutant emission reduction in maturing alternative fuel pathways was evaluated. Working groups provide a collaborative framework facilitated by the Center to jointly engage partners and external experts and companies on specific topics to deliver clear and impactful results.

Project Objective

Determine the impact and role of vessel greenhouse gas and air pollutant emission reduction in maturing alternative fuel pathways

Onboard impact is defined in terms of tank-to-wake global warming potential with the role of onboard emission reduction either being for regulatory compliance or as an option to reduce emissions. Fuel pathway maturity is an assessment of solution readiness across the entire value chain including if vessels, fuel production plants or bunkering vessels can be ordered without technical risk, at realistic price levels and with underlying regulation in place.

Based on identified vessel emission risks, the working group completed deep dives into specific emissions that need to be addressed to increase alternative fuel pathway maturity. The objective of these deep dives is to understand current or potential emission levels, set reduction targets, and identify and map applicable technologies and solutions. Emission reduction potential is then determined, and recommendations given to mature the selected fuel pathways. Finally, areas or concepts for further research and development are identified including recommended future project topics.

An introduction to onboard emission sources, main risks, and solution mapping is provided in an introduction paper entitled “Determining the impact and role of onboard vessel emission reduction.” Deep dives and reviews are covered by individual papers on specific emissions within the paper series. The first three focus on methane slip, ammonia combustion and biofuel usage and emissions. Potential future topics include a broad assessment of particulate matter including black carbon for all main fuel alternatives as well as a complete assessment of emissions from methanol combustion.
