HD Hyundai Heavy Industries has developed the first medium sized cargo ships capable of running on ammonia. The vessels, named Antwerpen and Arlon, feature dual fuel engines and a capacity of 46,000 cubic meters. Ammonia is a key alternative for heavy maritime transport because it contains no carbon in its molecular structure. Using it as a fuel source allows shipping companies to eliminate direct CO2 emissions during combustion.

HD Hyundai is moving on ammonia ships for Exmar. These two vessels have a 46,000 cubic meter capacity and use dual fuel engines to cut CO2. It is a concrete step for heavy shipping, but we need to see the actual fuel source.

The ship is one thing, but the bunkering infrastructure is another. Where is the green ammonia coming from? If it is grey ammonia from natural gas, the carbon footprint just shifts upstream. Does the article mention the supply chain for the fuel?

That is the core issue. Without strict carbon accounting and certification for green ammonia, these ships are just a hardware update. The real win happens when fuel subsidies shift from fossils to zero carbon feedstock.

Curious about the maintenance costs of ammonia engines compared to standard diesel. Ammonia is corrosive and toxic, so the safety systems and crew training will add significant overhead to the operating budget.
