  • J-ENG successfully launched the country’s first large, low-speed two-stroke marine engine capable of co-firing with ammonia, a zero-emission fuel.
  • The project is a key component of NEDO’s Green Innovation Fund, aimed at advancing next-generation, zero-emission ships.
  • The engine is scheduled for shipment in October 2025 for installation on an ammonia-fueled gas carrier, marking the start of real-world demonstration trials.

Japan Engine Corporation (J-ENG) has launched Japan’s first large-scale, low-speed, two-stroke marine engine capable of co-firing with ammonia, reads an official release.

This achievement is a major leap in the global shift toward decarbonized shipping and supports Japan’s goal of achieving carbon neutrality by 2050.

Green Innovation Project

This development falls under the “Green Innovation Fund Project: Next-generation Ship Development,” sponsored by Japan’s New Energy and Industrial Technology Development Organization (NEDO). The project focuses on pioneering zero-emission marine technology.

Since May 2023, J-ENG has conducted extensive tests on the 7UEC50LSJA-HPSCR engine, confirming stable ammonia co-firing and safe handling practices. This testing phase provided valuable data for further engine optimization.

Looking Ahead: Engine Delivery and Trials

The engine is scheduled to be shipped in October 2025 and will be installed on an Ammonia-Fueled Medium Gas Carrier (AFMGC). Demonstration voyages are expected to follow, testing real-world performance.

To support demand and expand capacity, J-ENG plans to build a new manufacturing facility. This initiative is funded by Japan’s Ministry of the Environment and the Ministry of Land, Infrastructure, Transport and Tourism via GX Economic Transition Bonds.

J-ENG’s innovations mark a significant step toward cleaner seas and a greener global maritime industry. With this pioneering effort, Japan is solidifying its role in shaping sustainable shipping solutions.
