TOKYO -- With decarbonization emerging as a priority in the traditionally emissions-heavy shipping industry, Japan's Imabari Shipbuilding aims to launch a cargo vessel that runs entirely on ammonia by 2026.

No ammonia-powered ships have been built to date, but the fuel is considered a key green energy source for the future. Imabari looks to take a lead in the cutting-edge field both in terms of technology and rule-setting, possibly regaining some of Japan's market share in shipbuilding lost to China and South Korea over the last several decades.
