Ammonia contains no carbon, so burning it as a ship fuel produces no CO₂. That makes it a leading candidate for deep-sea decarbonisation. It is also toxic, corrosive to some materials and hazardous to people even at low concentrations. Our approach starts from that reality.
The world is moving from talk to practice. Ammonia bunkering for an ammonia dual-fuel vessel has already been carried out at Ulsan, South Korea, and India is building the supply base: renewable ammonia production is ramping up at projects such as AM Green’s mega-project.
In February 2025 IMO issued MSC.1/Circ.1687, Interim Guidelines for the Safety of Ships Using Ammonia as Fuel. They are non-mandatory but provide a goal-based safety framework for ship design, equipment, operations, bunkering, toxicity mitigation and crew protection. Key expectations include refrigerated storage at atmospheric pressure, inerting and gas-freeing of bunkering lines, secondary enclosure of fuel pipes, and no expansion joints or bellows in ammonia piping. We design and plan operations to these principles and to applicable Indian regulations.
