The International Maritime Organization's (IMO) initial 40% GHG reduction targets by 2030 and decarbonizing shipping entirely by 2050 by achieving net-zero emissions targets necessitate a multi-pronged effort. National and port authorities are also raising their environmental standards; currently, the only available solution to meet the IMO goals is to switch to an alternative fuel, Liquefied Natural Gas (LNG), which provides an immediate benefit in terms of carbon, Sox, and NOx reductions. It is widely available, inexpensive, and the only alternative fuel with an existing and well-established infrastructure.
LNG conversion is a well-established and viable path toward more sustainable fuels, and it plays an important role not only in reducing ship carbon footprints but also in assisting in the elimination of other pollutants. It also opens up the possibility of adopting future green fuels, such as bioLNG or synthetic methane, without requiring major changes. According to research data on ships and vessels that have already been converted to LNG, the results prove that they have a significant reduction of around 85-90 percent in NOx emissions, 99 percent in Sox, and 20 percent reductions in CO2 emissions and other particulate matters.
