LNG's GHG emissions can be cut, says Wärtsilä

摘要

Wartsila claims LNG is the fastest, simplest pathway for shipping to achieve IMO's 2050 goal of halving shippings greenhouse gas (GHG) emissions. While software company Thinkstep states that LNG engines emit less GHG than HFO, a report by the International Council for Clean Transport (ICCT) claims gas engines are worse emitters than conventional diesel. However, Wartsila notes that ICCT's report calculates a 5.5g/kWh methane slip based on a low-pressure, duel-fuel medium-speed gas engine and does not reflect the latest advancements in gas engine technology.
