The shipbuilding sector continues to report strong progress in developing future designs to use ammonia as the primary fuel. Designers are working to develop ships in each of the primary categories that in the future will be able to use the new fuels and provide shipowners a viable migration path to future-proof current investments in ships. Japan’s Mitsubishi Shipbuilding and South Korea’s Samsung Heavy Industries each reported design approval for additional ships designed to employ ammonia as their primary fuel.
