Partners start development of large-size ammonia carrier

Aims set on achieving operation of vessels fueled by ammonia – a clean energy – and increasing volume of marine transportation of ammonia

Partners start development of large-size ammonia carrier

Mitsubishi Shipbuilding Co., Ltd., a part of Mitsubishi Heavy Industries, Ltd. (MHI) Group, has reached an agreement with Mitsui O.S.K. Lines, Ltd. and Namura Shipbuilding Co., Ltd. on joint development of large-size ammonia carrier fueled by ammonia.

Ammonia is mainly used as a raw component of fertilizers, and is expected to be a high-quality, reliable and clean energy. The development aim to increase the volume of marine transportation of ammonia by large-size ammonia carrier which are fueled by ammonia. 

The three companies will jointly proceed with the development of basic design of large-size ammonia carrier where Mitsubishi Shipbuilding will take charge of the optimal design of cargo tank and deck tank used for ammonia fuel, organizing engine and related machinery systems including the fuel supply system, and development and design of cargo handling equipment, special equipment for ammonia transportation and safety equipment onboard.

In the years ahead, ammonia fuel is anticipated to increase in demand in the future as a next-generation clean energy that does not emit CO2 when burned, and as the global value chain of maritime industry shifts to decarbonization, it is highly expected as a long-term solutions for marine logistics. Ammonia is considered to be a promising choice for realizing carbon neutrality in Japan as well, and its demand is expected to increase especially in applications involving replacement of existing fuels in thermal power plants and as a hydrogen carrier.
