Kawasaki Heavy Industries, Yanmar Power Technology and Japan Engine Corporation (J-Eng) have formed a consortium of Japanese engine manufacturers to pursue joint development of hydrogen fuelled marine engines for ocean-going and coastal vessels, looking towards establishing a world-leading position in hydrogen engine technologies.

With the growing need to reduce greenhouse gas emissions, marine engines are expected to transition to various alternative fuels in the coming years. Among the many alternatives, hydrogen is attracting global interest for its application in a wide range of energy and mobility industrial sectors as a fuel that offers zero-emissions. The companies are looking to develop technologies in the hydrogen value chain towards global expansion of this important alternative fuel. By cooperating on common fundamental technologies such as basic experiments and analysis on hydrogen combustion, materials, and sealing techniques, as well as classification society requirements, each company aims to bring hydrogen-fuelled engines to the market by 2025.

Kawasaki Heavy Industries will develop medium-speed four-stroke engines, Yanmar Power Technology will focus on medium- and high-speed four-stroke engines, and Japan Engine Corporation will embark on the development of low-speed two-stroke engines. All three simultaneous developments will enhance the product line-up of propulsion and auxiliary (generator) engines for a wide range of vessels. In addition, a hydrogen fuel storage and supply system will be developed as part of the integrated hydrogen fuel system.

By developing advanced hydrogen marine engine technologies based on the distinctive engines and quickly launching in the market, the consortium will contribute to the Japanese shipbuilding industries. Furthermore, the companies aim to revitalise the Japanese maritime industries and realising a sustainable society by promoting the uptake of hydrogen fuelled engine technology for marine vessels.
