Methane slip from gas-fuelled ships back in the spotlight

Within the space of a week there have been three future fuel reports with very different takes on today’s controversial leading alternative fuel, LNG.

Likely grabbing the most headlines is an 80-page report from the Washington DC-based International Council on Clean Transportation (ICCT) which claims real-world methane emissions from LNG-fuelled ships are higher than current regulations assume. 

Policymakers have been urged to consider increasing the default methane slip value to at least 6% for the most common LNG engine on the back of the ICCT study which is based on data collected by drones, helicopters, and onboard sensors during the two-year Fugitive and Unburned Methane Emissions from the Ships (FUMES) project, a collaboration between the ICCT, Danish emissions monitoring firm Explicit, and the Netherlands Organization for Applied Scientific Research (TNO).
