The operation took place at COSCO Shipping Heavy Industry’s terminal in Dalian, China, where China Shipping & Sinopec Suppliers Co., Limited bunkered green ammonia fuel for a 5,500 HP ammonia-fueled port tugboat.
The fuel was produced at Envision’s Chifeng Green Hydrogen-Ammonia Project, the world’s largest green hydrogen and ammonia facility. The site integrates wind and solar energy with storage and proprietary hydrogen and ammonia production technologies to deliver what Envision describes as the most cost-effective green ammonia on the market. The project has received ISCC Plus certification, as well as renewable ammonia certification from Bureau Veritas.
The port vessel used in the demonstration is equipped with an independently developed ammonia dual-fuel engine and a dedicated fuel supply system. It achieves an ammonia substitution rate of up to 91% and has been classified as an ‘Ammonia Fuel Tug’ by the China Classification Society.
“This successful bunkering demonstrates how net zero fuels can scale from renewable power generation to hard-to-abate sectors like maritime shipping – a true breakthrough for green ammonia,” said Frank Yu, Senior Vice President of Envision Energy. “We are proud that our green ammonia powered the world’s first bunkering of its kind. It’s a testament to Envision’s ability to deliver end-to-end net zero solutions that accelerate the replacement of fossil fuels with green energy in shipping and redefine what’s possible for the broader industrial transition.”
With this operation, Dalian Port becomes the first in the world to offer bunkering services for biofuel, green methanol, LNG, and green ammonia. Envision Energy states that the event establishes a complete value chain for green ammonia – from production and transport to bunkering and end use – and sets a scalable blueprint for the global adoption of net-zero shipping fuels.
