The system reduces methane slip by placing a methane oxidation catalyst in an LNG fuel engine and oxidizing the methane. This is the first time in the world that a catalytic methane oxidation system has received approval in principle (Note 2).
This project was adopted by the
The project aims to further reduce the environmental impact of the LNG fuel engine by achieving a methane slip reduction rate of more than 70% over a six-year period from FY 2021 to FY 2026 by combining a methane oxidation catalyst and engine improvements and by verifying the design concept in actual vessels. The approval is an important first step towards establishing the technology for this system.

Note 1: Methane Oxidation Catalyst System
This system is placed in the exhaust pipes of LNG fueled engines and generators that contain unburned methane, and the methane is oxidized on the catalysts to reduce methane slip.
Note 2: Approval in principle
An AiP is issued to equipment and systems that are unprecedented or have very little precedent where the
Note 3: Methane slip
In gas engines, part of the methane in the LNG fuel is emitted into the atmosphere as unburned methane, via the exhaust gases. Methane has a greater greenhouse effect than CO2, and reducing methane releases is necessary to achieve greenhouse gas reductions.

MOL develops various social infrastructure activities such as maritime activities and wind energy activities, focusing on maritime transport activities such as dedicated vessels that transport various raw materials and fuels, tankers and ships transportation of products such as automobiles. With the largest fleet in the world, experience and technology cultivated over 130 years of history, and a spirit of challenge aimed at creating new value, we contribute to the development of the world economy and the preservation of ‘environment. In this project, we aim to further reduce the environmental burden of LNG-powered ships by establishing how methane reduction technology works on real ships. We will contribute to the reduction of greenhouse gas emissions from our ships, the low carbonization of the supply chains of customers such as shippers and the low carbonization of society as a whole.
