MITSUI AIMS FOR LEADING POSITION IN AMMONIA-FUELLED SHIPBUILDING MARKET

Dec 29, 2025 | Shipbuilding & ship repair news

Mitsui E&S has announced that its ‘Plan to Increase Production Capacity of Ammonia-Fuelled Propulsion Systems’ has been selected as one of the subsidised projects under the Japanese Ministry of the Environment’s and Ministry of Land, Infrastructure, Transport and Tourism’s public ‘Zero Emission Ship Construction Promotion Project’.

The project aims to lead the global effort in reducing CO₂ emissions by establishing a domestic production system for zero-emission ships and accelerating their market adoption, thereby strengthening industrial competitiveness and driving economic growth.

As GHG reduction in the maritime sector is becoming a pressing issue, Mitsui E&S has produced low environmental impact products such as LNG, LPG, and methanol fuelled engines which are ready for future net-zero GHG emission fuels and furthermore, by using this subsidy programme, will accelerate the production of ammonia fuelled products, engines and fuel supply systems. Mitsui E&S aims to increase its production capacity of dual fuel engines tenfold by 2040, mainly ammonia fuelled engines offering a zero GHG emission solution in order to achieve the IMO target for net-zero GHG emissions by or around, i.e. close to, 2050, as early as possible.

Japan’s marine industry aims to double shipbuilding capacity by 2035. By investing in production facilities for ammonia fuelled propulsion systems in addition to leveraging its strengths such as manufacturing capacities, Mitsui E&S says it is committed to expanding the global share of ships built in Japan and to the growth of shipping industry and will aim to achieve a global market share of 20% over for ammonia fuelled propulsion systems and maybe achieve the leading market share.
