ETI Insights Report - Targeting a 30% improvement in fuel efficiency for marine vessels

Abstract:

This ETI Insights document summarises the findings of ETI's Marine Heavy Duty Vehicles project. Key headlines are:<ul> <li>Shipping emits substantial amounts of CO₂ which, without significant intervention, will rise as a proportion of our national emissions as we become less carbon dependent in other industry sectors</li> <li>Ocean voyaging ships have the biggest impacts on CO₂ emission due to the length and speed of their voyages and the current calculation method1 underplays the UK's share of international shipping carbon emissions</li> <li>There are economic advantages to emitting less carbon (and the economics of such are more cost-effective than some other carbon abatement opportunities in marine and other sectors)Using non-fossil fuels such as nuclear or high levels of biomass does not appear credible in the timeframe assessed</li> <li>In the medium to long term (to 2050), the best potential to achieve substantial CO₂ reduction is by fuel consumption reduction</li> <li>ETI modelling has shown that a 30% fleet fuel consumption reduction can be achieved using innovative technologies with an economic payback period of around two years and a fuel price of $720/Tonne</li> <li>For the opportunity to materialise, fuel-saving technology demonstration is needed to give confidence to stakeholders and overcome market barriers</li></ul><!-- CO2 -->
