Chinese wind turbine and energy management software company Envision Energy has announced what it calls the first bunkering of green ammonia fuel. The maritime fuel was produced from a green hydrogen and ammonia plant in Chifeng.
China Shipping & Sinopec Suppliers completed the inaugural bunkering of green ammonia fuel for a 5,500 HP ammonia-fueled port vessel. Envision said this demonstrates that the entire value chain, from green ammonia production to transportation, bunkering, and operation of ammonia-powered vessels, is now fully established.
“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.”
The company said its Chifeng Green Hydrogen-Ammonia Project is the world’s largest and most cost-effective facility of its kind. The project integrates wind, solar, and energy storage with proprietary hydrogen and ammonia production technologies. It has been awarded the ISCC Plus certification, becoming the world’s first project certified for green ammonia with a verified GHG (greenhouse gas) footprint. Additionally, the green ammonia produced has received renewable ammonia certification from Bureau Veritas.
The port tugboat that received the green ammonia fuel is equipped with 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.
Envision said this positions Dalian Port as the world’s first port capable of offering biofuel, green methanol, LNG, and green ammonia bunkering, filling a critical gap in the supply chain for green ammonia marine fuel for international trade vessels.
