Mitsui OSK Lines (MOL) is teaming up with Namura Shipbuilding and Mitsubishi Shipbuilding to develop a large ammonia carrier.
The size of the design was not disclosed, but it will be powered by ammonia as MOL looks to reduce greenhouse gas emissions from its fleet.
"Currently, ammonia is used mainly as a raw material for fertiliser, but its maritime transport volume is limited," MOL said.
