GREEN RAY TECHNOLOGIES
The GREEN RAY project aims at minimising methane slip from Liquified Natural Gas (LNG) engines and reducing the environmental impact of waterborne transport. Three technologies will be developed for LNG engines on both existing and new ships and aim to increase overall engine efficiency and reduce nitrogen oxide emissions while maintaining low sulphur oxide and particulate matter emissions.
GREEN RAY will be targeting the low-pressure dual fuel concept, as this is the most popular LNG engine technology. To address the issue from multiple angles, the project will provide solutions to reduce methane slip in two- and four-stroke engines as well as tackle the remaining methane slip through the development of an aftertreatment technology to convert the escaping methane into a less potent greenhouse gas (GHG).
All these technologies developed in GREEN RAY will also be fully capable to utilize bio- or synthetic methane instead of fossil LNG.
