Mitigating methane slip in LNG engines


5 years

2022 - 2027





The GREEN RAY project aims at minimising the methane slip from Liquified Natural Gas (LNG) vessels to enable clean waterborne transport. By developing three innovative technologies for LNG engines that can be installed on new and existing ships, GREEN RAY is working to reduce the negative impact of waterborne transport and protect human and environmental health.

GREEN RAY will be targeting low-pressure dual fuel concept, as this is the most popular LNG engine technology, and it is also the technology that produces the most methane slip. To tackle the issue from multiple sides, the project will provide solutions to reduce methane slip in two- and four-stroke engines as well as tackling remaining methane slip through the development of an aftertreatment technology to convert the remaining escaping methane into a less potent greenhouse gas (GHG).

The GREEN RAY project has received funding from the European Union’s Horizon Europe research and innovation programme under grant agreement No 101056642.
