-23% greenhouse gas emissions by using LNG, according to a recent study
14 Jun 2021 - ConferenzaGNL
According to a recent study commissioned by Sea-LNG and SGMF (Society for Gas as a Marine Fuel) to the consultancy firm Sphera, the use of Liquefied Natural Gas in maritime transport would allow a reduction of CO2 emissions up to 23%, depending on of the technologies used.
The study, entitled “2nd Lifecycle GHG Emission Study” is based on data provided by ship engine builders and major oil companies and updates the results of a research carried out in 2018/2019, offering new insights into the potential of LNG.
According to the study, LNG can guarantee a reduction of emissions in the order of 14/23% on two-stroke engines (slow-speed engines) mounted on board large ships, while on four-stroke engines (medium- speed engines) reductions range from 6 to 14%.
It should be noted that in addition to ensuring greater CO2 reductions, two-stroke engines have a lower loss of unburnt methane, a significant source of emissions. Analysts argue that the environmental impact produced by methane spills in shipping will be eliminated by 2030 thanks to the introduction of new technologies in marine engines.
