LNG has a much better emissions performance than conventional fuels and solutions. LNG far out-performs conventional marine fuels on a local emissions basis, effectively insulating companies from the impact of future, more demanding, regulation. LNG emits zero SOx and virtually zero particulate matter. Compared to existing heavy marine fuel oils, LNG can, depending on the technology used, emit 90% fewer NOx emissions.
LNG’s greenhouse gas (GHG) performance represents a major step forward when compared with traditional marine fuels.
Utilising best practices and appropriate technologies to minimise methane leakage, realistic reductions of GHG by 10-20% are achievable, with a potential for up to 25% compared with conventional oil-based fuels.
In the longer term, as pressure grows on the shipping sector to contribute even more to global GHG reductions, LNG-fuelled vessels and bunkering infrastructure provide an obvious potential decarbonisation pathway through the substitution of conventional (fossil fuel) LNG with bio-LNG, as technology developments allow.
