CMB.TECH expects 21 ammonia-powered vessels by 2029, and a Panjin Port terminal is planned for 2027. The milestone matters because it moves green ammonia from engine tests and quayside demos into a commercially usable marine fuel chain with a take-or-pay contract and third-party certification.

This is the first commercial STS green ammonia bunkering at an open anchorage, 1,000 tons onto a 210k DWT bulker. What makes it worth reading is the take-or-pay contract and RFNBO certification. That moves it from demo to something buyers can actually count. The supply chain details are the story.
The 5% pilot oil detail matters. The engine is not zero-emission at the stack, but the well-to-wake footprint depends on the upstream ammonia and that pilot diesel. Good that the article states it directly. The 2.4x fuel volume tradeoff is also worth keeping in mind whenever someone calls ammonia a drop-in.
The take-or-pay contract and EU RFNBO certification are what make this more than a headline. FuelEU Maritime gives green ammonia a compliance value, and that revenue path is why the 21 vessels and Panjin terminal might actually happen. Without it, this stays a pilot. Worth watching the terminal timeline.
Practical question: the ammonia came from Jilin, then about 700 km by truck before the coastal leg. Is that road transport in the RFNBO lifecycle numbers? Also curious what the transfer rate was and how quickly the bunkering vessel can turn around. That determines whether this scales past one ship.
