This week, Japan Engine Corporation (J-ENG) announced the launch of a new R&D program, in collaboration with the National Maritime Research Institute, that focuses on engine development for "combustion of carbon-free fuel (e.g. hydrogen and ammonia)."
Five hundred miles across the Sea of Japan, DSME has completed a techno-economic feasibility study comparing three fuels: HFO (with scrubber), LNG, and ammonia. The results of this study will be presented at the Ammonia Energy Conference, in Orlando, FL, on November 13. DSME is one of the three big shipbuilders in South Korea, and its business case for ammonia is strong enough that now "DSME is planning to expand our technology and business to NH3 engineering and systems for commercial ships."
