LNG dual-fuel ME-GI engines selected for newbuild liquefied CO2 carriers
China’s Dalian Shipbuilding Industry has ordered two MAN B&W 7S35ME-GI dual-fuel engines in connection with the construction of two 7,500-m3, liquid CO2 carriers for Northern Lights
Each of the two-stroke, Diesel-cycle ME-GI engines will have MAN Energy Solutions’ proprietary EcoEGR exhaust gas recirculation system. The 130-m LCO carriers will be delivered mid-2024.
Northern Lights, a joint venture between Equinor, Shell and TotalEnergies, is responsible for developing and operating CO2 transport and storage facilities as part of ‘Longship’, the Norwegian Government’s full-scale, carbon-capture-and-storage project. Northern Lights will create the first ever, cross-border, open-source, CO2 transport-and-storage infrastructure network, offering European companies the opportunity to store their CO2 safely and permanently underground.
MAN Energy Solutions chief sales officer and executive board member Wayne Jones said, “With the current focus in the maritime world on reducing methane slip, our dual-fuel ME-GIs will keep carrier emissions to a minimum in this project whose green credentials will be carefully examined.” Mr Jones added the new LCO carriers “enable the revolutionary development of a flexible and efficient, European infrastructure for CO2 capture from industrial customers.”
The newbuilding carriers will be used in the first phase of Northern Lights’ transport-and-storage-infrastructure development and are designed to transport liquid CO2 in purpose-built, pressurised cargo tanks. The dual-fuel ME-GI engines will mainly burn LNG, while other innovative technologies – such as a wind-assisted propulsion system and air lubrication – will be installed to reduce carbon intensity by around 34%, compared with conventional systems. The ships are the first of their kind and have the potential to set a new standard for CO2 shipping on coastal trading routes.
The Northern Lights project allows for further phases to expand capacity through future investments triggered by market demand from large CO2 emitters across Europe.
Norcem carbon-capture project
The Norwegian Government’s Longship project aims to demonstrate that carbon-capture technology can be applied to larger industrial plants and set a new standard for future industrial projects. The HeidelbergCement Norcem plant near Oslo will be the first to use the carbon capture heat recovery technology (CCWHR) developed by MAN and Aker Carbon Capture from mid-2024 when it will capture 400,000 tonnes of CO2 annually, corresponding to 50% of its overall emissions. The gas will be compressed, liquefied and subsequently transported by Northern Lights using the new carriers to their onshore receiving terminal near Bergen in western Norway, from where a pipeline will lead to an underground storage location in the North Sea.
MAN Energy Solutions chief executive Dr Uwe Lauber said, "CO2 emissions are currently unavoidable in cement production, with the sector accounting for 6 to 7% of the world’s carbon-dioxide emissions. This is why the cement industry is key on the road to a decarbonised future.”
MAN Energy Solutions’ scope of supply for the cement factory includes an electrically powered compressor train – type RG 63-7 with integrated CCWHR technology – which allows the compression heat of the recovery compressor to be exploited. The steam generators cool the CO2 mixture between the compressor stages and generate steam that is in turn used for capture.
