SEA\LNG Coalition Highlights Emissions Reductions

LNG bunkering coalition SEA\LNG has found that the use of LNG as a marine fuel could cut greenhouse gas (GHG) emissions by up to 23% (LNGI Mar.25'21). The use of LNG as a low-carbon marine fuel continues to gain traction with new ships running on LNG and a buildout of related infrastructure (LNGI Mar.11'21; LNGI Mar.19'21). Although LNG does not have the low-carbon transport market to itself (LNGI Mar.10'21). In an independent study published on Apr. 16, SEA\LNG said that the reduction in GHG via the use of LNG as a bunkering fuel was compared to emissions from current oil-based marine fuels, measured from well-to-wake. Methane emissions from the supply chains as well as methane released during the onboard combustion process -- also known as methane slip -- have been included in the analysis, SEA\LNG confirmed. The study also reaffirms air quality benefits associated with LNG as a maritime fuel, with local emissions including sulfur oxides, nitrogen oxides and particulate matter, "all close to zero." SEA\LNG added that in addition to the considerable air quality benefits it delivers, LNG can “beyond question” contribute significantly to the International Maritime Organization’s GHG reduction targets. Going forward, SEA\LNG chairman Peter Keller says that it is "essential that detailed emissions analysis from Well to Wake, such as those performed for LNG, are available for all alternative fuels contemplated, enabling shipowners to make the right decisions for their fleet.” The chairman added that methane slip is often based on outdated data and has become "an overused argument for those wishing to justify inaction." The study underlines the advances being made to counteract this concern. Puget LNG was the latest company to join the ranks of SEA\LNG this week (LNGI Apr.13'21).
