J-ENG to develop methanol-fuelled marine engine with 2027 completion goal

Japan Engine Corporation (J-ENG) on Tuesday (16 December) said it has commenced development of the methanol-fuelled marine engine, UEC50LSJM. 

Following the completion of its first ammonia-fuelled engine, 7UEC50LSJA, in August of this year, J-ENG is also working on the development of the hydrogen-fuelled engine, 6UEC35LSGH. 

“Based on the knowledge and know-how gained from the development of these new fuel engines, J-ENG will develop an engine that uses methanol, another alternative fuel candidate, in a short period of time, with the goal of completion within fiscal year 2027,” the company said on its website. 

Methanol is a low-carbon fuel that has the effect of reducing GHG (Greenhouse Gas) emissions, as well as sulfur oxides (SOx), nitrogen oxides (NOx), and particulate matter. 

The company added methanol also has the advantage of being a liquid under normal temperature and atmospheric pressure, making it relatively easy to handle, and is expected to be applied in many ship types, including medium and small-sized vessels. 

Furthermore, in the future, it is also expected to contribute to a significant reduction in GHG emissions through the supply of green methanol derived from biomass and renewable energy.

“As a first mover in the next-generation fuel engine field, J-ENG will contribute to the growth of Japan’s shipping and shipbuilding industries through the development and market introduction of a wide variety of engines,” the company added.

“At the same time, J-ENG will contribute to GHG reduction in the shipping industry and the realisation of carbon neutrality by 2050.”
