The results of a new analysis by the International Council on Clean Transportation (ICCT) show that, when combined with a trend toward higher methane leakage and combustion slip, there is no climate benefit from using liquefied natural gas (LNG) as a marine fuel—regardless of the engine technology. LNG is becoming popular for several reasons. First, it contains very little sulfur. Additionally, LNG engines are tuned to either emit low nitrogen oxide (NO x ) emissions—at the cost of higher methane emissions in some cases—or to incorporate NO x reduction technologies such as exhaust gas recirculation (EGR) or selective catalytic reduction (SCR). These low sulfur oxide (SO x ) and NO x emissions make LNG an attractive fuel for ships that operate in Emission Control Areas (ECAs), where ships must comply with more stringent air quality standards. Second, LNG is, and has been, less expensive than MGO and is now […]
