The recently launched GREEN RAY initiative, coordinated by VTT Technical Research Centre in Finland, is aiming to develop three solutions for reducing methane slip from LNG-fuelled engines in both new and existing vessels, says an article published in BunkersSpot.
The five-year project, which launched last month, has received a €7 million grant from the European Commission under the new Horizon Europe research and innovation programme.
Other companies participating in the initiative are Chantiers de l’Atlantique, CMA Ships, Wärtsilä, Shell, DNV, the Finnish Meteorological Institute, MSC Cruises Management, MSC Malta Shipyard Management, and REVOLVE communications agency.
The GREEN RAY project is focused on low pressure, dual fuel engine technology.
The consortium will develop two engine technologies and one after treatment technology for existing ships and newbuilds.
The first engine-based approach will focus on reducing methane slip at all engine loads for four-stroke engines and would have applications in the cruise, ferry and gas carrier markets.
The project will also focus on developing a solution for two-stroke engines, based around a patented LNG injection system, and this would have applications for the tanker and containership segments.
The third solution within the scope of the programme will be the development of a sulphur resistant catalyst system which would potentially reduce methane slip emissions by up to 95% and reduce methane slip to less than 1G/kWh.
All the technologies will be demonstrated onboard two new ships and one retrofit to existing vessels, all of them targeting the Technology Readiness Level (TRL) 7: System prototype demonstration in an operational environment.
