ICCT life-cycle analysis finds no climate benefit in using LNG as marine fuel

Green Car Congress

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. First, it contains very little sulfur.

MAN ES reports Tier III exhaust-after-treatment orders for low-speed engines pass 1,000

Green Car Congress

Approximately one-quarter of the orders have been for EGR (Exhaust Gas Recirculation) systems, with SCR (Selective Catalytic Reduction) systems accounting for the remainder. The milestone was passed in early January 2021 and is built upon references from the company’s portfolio of ME-B, ME-C and MC-C fuel-oil engines.

UBC researchers find life-cycle GHG benefits of LNG in marine shipping only from high-pressure dual-fuel engines in ocean-going vessels

Green Car Congress

A life-cycle assessment of emissions from domestic and imported liquefied natural gas (LNG), and heavy-fuel oil (HFO) for marine shipping by a team from the University of British Columbia has found that only high-pressure dual-fuel (HPDF) engines robustly reduce well-to-wake GHG emissions by 10% compared with their HFO-fueled counterparts.

Federal-Mogul marine piston ring technology reduces oil consumption and pollution from two-stroke diesels

Green Car Congress

Federal-Mogul Powertrain, a division of Federal-Mogul Holdings Corporation, has developed a new piston ring for two-stroke diesel engines that reduces oil consumption and marine pollution by allowing the quantity of lubricant used to be greatly reduced. This feed oil is not uniformly distributed on the cylinder wall.
