The U.S. market is driven by aggressive federal and state-level environmental policies, such as California’s clean air rules and the federal push for decarbonization under the Inflation Reduction Act. The DOE's support for alternative fuels and maritime sustainability grants has provided crucial momentum for ammonia-diesel engine adoption. Coastal hubs like Los Angeles, Seattle, and Houston are becoming focal points for alternative fuel demonstrations. Technological innovation and pilot demonstrations, especially along the Gulf Coast and West Coast ports, are expanding the application base of ammonia-diesel engines in tugboats, ferries, and commercial ships. However, regulatory clarity on ammonia handling, fuel quality standards, and crew safety protocols remains a concern. Involvement from naval institutions, academia, and industrial consortia adds to the momentum. The U.S. market is expected to grow steadily as policies mature and infrastructure gaps are addressed.
