Seven steps to safe, approved use of ammonia or hydrogen ship fuel

Thinking about running ships on ammonia or hydrogen? Read about a smart way to gain approval under IMO’s alternative design approval process.

Our latest article on maritime decarbonization summarizes how shipowners can apply a practical, structured approach to gaining approval for ammonia- or hydrogen-fuelled ships. From engaging early with flag administrations to addressing design risks, training crews, and managing bunkering safely, we describe seven essential steps to receive approval.
