Japanese duo to develop ammonia and hydrogen marine engines

Japan Engine Corporation (J-ENG) and Akasaka Diesel plan to complete the ammonia engine by 2025, and the hydrogen engine by 2026, J-ENG says.

This will be J-ENG's first ammonia-fuelled engine, which will have a bore size of 50 cm and power of 8,000 kW (kilowatts). The hydrogen-fuelled engine will be a two-stroke engine with a bore diameter of 35 cm and a power output of 5,000 kW, says J-ENG says.

The engine's bore size represents the piston diameter in centimetres. It varies with the type and size of the vessel.

The duo aims to apply the technologies used in developing the ammonia and hydrogen engines “to a wide variety of new fuels such as methanol”, J-ENG adds.

The two companies will make these engines under the Green Innovation Fund Project, which has been sponsored by Japan's New Energy and Industrial Technology Development Organization (NEDO).

NEDO is Japan’s national government fund and innovation accelerator for technical research required for the projects.
