This guidance document has been developed to provide a basic understanding of fuel cell technology and of how the technology is expected to be integrated and used on board ships, and to outline important considerations in the early concept and design phases.

The guidance is particularly intended for Shipbuilders and shipowners considering the use of fuel cell technology in new ship designs or considering the retrofitting of fuel cell technology on board existing ships.

The guidance includes lessons learned and industry best practice to support practical implementation and problem-solving.
