LNG on the road – the bottom line [LNG Condensed]
A number of recent studies have cast doubt on the extent of greenhouse gas emissions reductions to be gained from the adoption of LNG in transport. A report by Imperial College London’s Sustainable Gas Institute published in January suggested 16% GHG emissions savings on a full life cycle basis for road transport and 10% for shipping. An industry commissioned study unveiled in April by consultancy Thinkstep estimated well-to-wake reductions of 7-21%.
Most pessimistic of all was a study published in October 2018 by the European Federation for Transport and Environment, which concluded that “based on the latest available evidence fossil gas used in transport has no meaningful - and when including methane leakage and upstream effects in almost all cases no - climate benefits compared to petroleum based fossil fuels.” Yet this study too provided ranges showing some savings, -2% to +5% for trucks and -12% to +9% for ships compared with marine diesel rather than high sulphur fuel oil (HSFO).
