ICCT life-cycle analysis finds no climate benefit in using LNG as marine fuel

Green Car Congress

The results of a new analysis by the International Council on Clean Transportation (ICCT) show that, when combined with a trend toward higher methane leakage and combustion slip, there is no climate benefit from using liquefied natural gas (LNG) as a marine fuel—regardless of the engine technology.

UBC researchers find life-cycle GHG benefits of LNG in marine shipping only from high-pressure dual-fuel engines in ocean-going vessels

Green Car Congress

A life-cycle assessment of emissions from domestic and imported liquefied natural gas (LNG), and heavy-fuel oil (HFO) for marine shipping by a team from the University of British Columbia has found that only high-pressure dual-fuel (HPDF) engines robustly reduce well-to-wake GHG emissions by 10% compared with their HFO-fueled counterparts.
