Japan Engine Corporation (J-Eng) has commenced the development of its methanol-fuelled UEC50LSJM engine.
Following the completion of its first ammonia-fuelled engine, 7UEC50LSJA, in August 2025, J-Eng is also working on the development of the hydrogen-fuelled 6UEC35LSGH engine. Based on the knowledge and experience gained from the development of these new fuel engines, J-ENG aims to 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.
Methanol is a low-carbon fuel that has the effect of reducing GHG emissions, as well as SOx, NOx and particulate matter. Methanol 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 future, it is 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 says it will contribute to the growth of Japan’s shipping and shipbuilding industries through the development and market introduction of a wide variety of engines. At the same time, J-Eng will contribute to GHG reduction in the shipping industry and the realisation of carbon neutrality by 2050.
