Amogy, Mitsubishi complete a feasibility study of ammonia supply system

The two firms conducted the study to confirm the feasibility of collaborative concept designs for onboard hydrogen production and use on ammonia-powered ships.

Collaborative concept design involves a collective effort to resolve complex problems.

The duo carried out a feasibility study of a power train combining ammonia cracking and a hydrogen fuel cell system for ships, along with a hydrogen supply facility that transports hydrogen as a pilot fuel to an ammonia-fuelled engine.

The study is part of a Memorandum of Understanding (MoU) signed between US-based ammonia tech startup Amogy and Mitsubishi Shipbuilding, which is a subsidiary of the Japanese engineering firm Mitsubishi Heavy Industries (MHI).

Amogy has developed an ammonia cracking technology, which involves a power system that uses ammonia to generate hydrogen on ships. This system moves liquid ammonia stored onboard the vessel to a catalyst-based reactor. Ammonia is then broken down into nitrogen and hydrogen molecules, in what is termed “ammonia cracking”.

Last month, Amogy received certification from the American Bureau of Shipping for its ammonia-to-power technology.
