Envision Energy’s green ammonia successfully bunkered in Dalian

In China, Envision Energy announced that green ammonia fuel produced from its world’s largest green hydrogen and ammonia plant in Chifeng has successfully powered the world’s first green marine ammonia bunkering operation. The milestone event took place at COSCO Shipping Heavy Industry’s terminal in Dalian, where China Shipping & Sinopec Suppliers Co., Limited completed the inaugural bunkering of green ammonia fuel for a 5,500 HP ammonia-fueled port vessel. This historic achievement demonstrates that the entire value chain, from green ammonia production to transportation, bunkering, and operation of ammonia-powered vessels, is now fully established and marks a concrete step by Envision in pioneering the “New Oil” era, showcasing Envision’s leadership in advancing net zero fuels for the global shipping industry.

The port tugboat that received the green ammonia fuel is equipped with key technologies including an independently developed ammonia dual-fuel engine and a dedicated fuel supply system. The vessel achieves an ammonia substitution rate of up to 91%, significantly reducing reliance on traditional fossil fuels and effectively cutting carbon emissions during operations. This vessel has obtained the “Ammonia Fuel Tug” classification from China Classification Society, setting a benchmark for the future of green shipping technology.
