Assessing the potential of hybrid energy technology to reduce exhaust emissions from global shipping

Significance of output:

Global shipping’s fleet of 90,000+ vessels contributes 3- 4% to anthropogenic CO2 emissions. The International Maritime Organisation identified this could rise to 50% for CO2 unless new solutions are found for ship propulsion. The work, based on fundamental knowledge of ship propulsion (Molland, Turnock & Hudson, Ship Resistance and Propulsion, CUP, 2011) shows that hybrid coupling of energy storage and propulsion could be attractive even for large ships in helping reducing emissions of CO2 as well as NOx and SOx. This work is helping inform concept design of future ships. (David Connolly, D.Connolly@shell.com, Shell Shipping Technology).
