Methane slip \u2013 the next compliance target?<\/strong> <\/p>\n \u201cWith IMO aiming to cut greenhouse gas emissions by at least 50% compared to 2008 levels, LNG has a major role as a bridge fuel in moving towards a carbon-neutral future,\u201d says David Jung, Business Development Manager at Alfa Laval. \u201cHowever, the awareness of methane slip and its influence on global warming is increasing. New regulations are not unthinkable, and any improvement from today\u2019s environmental benchmark is important. With or without regulations, WinGD\u2019s iCER technology with the Alfa Laval PureCool system will help the shipping industry align more fully with climate goals by minimizing methane slip.\u201d<\/p>\n <\/p>\n PureCool and its contribution to iCER<\/strong> <\/p>\n \u201cThe iCER option is a standalone installation adjacent to the engine,\u201d says Jung. \u201cDuring operation in gas mode, it improves combustion by cooling and recirculating about 50% of the exhaust gas through a low-pressure path with full turbocharger capacity. This minimizes methane slip, and the PureCool system provides the vital cooling function that makes it possible.\u201d<\/p>\n <\/p>\n <\/strong><\/p>\n <\/p>\n Up to 50% methane slip reduction<\/strong> <\/p>\n \u201cThis is not fine-tuning or a marginal improvement of LNG technology,\u201d says Jung. \u201cThis is a major environmental gain that truly strengthens LNG\u2019s profile. With the PureCool system at its heart, iCER will cut methane slip by as much as half.\u201d<\/p>\n <\/p>\n Fuel and energy savings<\/strong> <\/p>\n \u201cThe PureCool system improves a vessel\u2019s efficiency along with its emissions,\u201d says Jung. \u201cThe fuel savings inherent to iCER can have a positive impact on a vessel\u2019s Energy Efficiency Design Index.\u201d<\/p>\n <\/p>\n A new aspect of lasting commitment<\/strong> <\/p>\n \u201cAlfa Laval is determined to stay at the forefront of developing solutions, both for environmental protection and for fuel progress,\u201d says Jung. \u201cThe PureCool system represents the two sides of that commitment equally. Above all, it shows our dedication to keeping customers prepared for the challenges ahead.\u201d<\/p>\n <\/p>\n
\nAs a growing number of vessels turn to LNG as fuel, many shipowners are concerned about the potential appearance of methane slip regulations. LNG produces less CO2 than other fossil fuels when burned, but a small percentage of methane can slip through the engine without being combusted. Since methane has a higher global warming potential than CO2, even this small source of emissions may come into focus in meeting IMO\u2019s ambitious climate goals.<\/p>\n
\nDeveloped by Alfa Laval in close collaboration with WinGD, PureCool is the cascade exhaust gas cooling system at the heart of the iCER concept. Short for Intelligent Control by Exhaust gas Recycling, iCER is the first development presented in X-DF2.0, WinGD\u2019s second-generation dual-fuel engine technology.<\/p>\n
\nThe effectiveness of iCER with PureCool is nothing short of remarkable. Trials at WinGD\u2019s dedicated engine test facility, which were the final step in a two-year testing programme, show a methane slip reduction of up to 50%.<\/p>\n
\nBeyond the methane slip reduction, the iCER solution with PureCool offers engine buyers significant operational benefits \u2013 thus creating value even prior to potential compliance regulations. When combustion is improved with iCER, fuel consumption in gas mode is reduced by 3%.<\/p>\n
\nAs iCER moves into the commercial phase and prepares for a first pilot installation, Jung is proud to see the PureCool system enter Alfa Laval\u2019s compliance portfolio. It joins successful solutions for a wide range of environmental challenges, but it is the first such solution related to non-traditional fuel.<\/p>\n
