In recent years, environmental awareness, including responses to climate change, has been increasing worldwide. Against this backdrop, the shipping industry is also working on various technological and business developments to realize a low-carbon society. One of these efforts is the introduction in various parts of the world of LNG-fueled ships, which have a low environmental impact. LNG fuel has the effect of reducing CO2 emissions, but engines using LNG can be prone to the problem of methane slip, where unburned fuel is expelled in the exhaust. Reducing methane slip is a pressing issue in engine design.
In this project, the partners aim to achieve a methane slip reduction rate of more than 70% for LNG-fueled vessels over a six-year period from FY2021 to FY2026. The reduction will be achieved by combining methane oxidation catalysts and engine improvements thereby further reducing the environmental impact of LNG-fueled vessels. YPT will also commission

(Note 1) Methane slip
A portion of the methane in LNG fuel is exhausted into the atmosphere as unburned methane. Methane has a higher greenhouse effect than CO2, and methane slip reduction is required from the perspective of greenhouse gas reduction.
Utilizing the technology cultivated as the only manufacturer of both 'catalysts' and 'marine diesel engines' in
MOL
MOL is developing various social infrastructure businesses such as marine business and wind energy-related business, centering on the shipping business such as dedicated ships that carry various raw materials and fuels, tankers, and product transport ships such as automobiles. With the world's largest fleet, experience, and technology cultivated over 130 years of history, and a spirit of challenge aiming to create new value, we are contributing to the development of the world economy and environmental conservation. In this project, we aim to further reduce the environmental load of LNG fueled ships by establishing the operation of methane reduction technology on actual ships. We will contribute to the reduction of greenhouse gas emissions from our vessels, the low-carbonization of customers' supply chains such as shippers, and the low-carbonization of society as a whole.
