Envision has brought online the world’s largest green hydrogen and ammonia production plant, marking a significant development in industrial-scale decarbonisation. The facility, located in Chifeng Net Zero Industrial Park in China, is powered entirely by an off-grid renewable energy system and is the first of its kind to be fully AI-enabled for real-time optimisation and operational stability.
The plant is currently producing 320,000 tonnes of green ammonia annually, with exports expected to begin in the fourth quarter of 2025. The site integrates energy storage and load flexibility at a commercial scale, converting surplus green electricity into liquid nitrogen stored in air-separation units, while electrolyzers adjust in real time to fluctuations in renewable power.
Advanced wind turbines, battery storage systems, and predictive meteorological models are used to balance energy inputs with production demands, enabling uninterrupted ammonia synthesis without reliance on the grid.
Envision’s green ammonia output is intended for use in sectors such as fertilisers, chemicals, and maritime fuel. A long-term offtake agreement has been signed with Japan’s Marubeni Corporation, underlining growing international interest.
The facility has received Renewable Ammonia Certification from Bureau Veritas, verifying compliance with sustainability, safety, and emissions standards.
By 2028, the industrial park is projected to reach an annual output of 1.5 million tonnes of green ammonia. Envision also aims to achieve price parity with conventional grey ammonia and methanol within the same timeframe.
Designed with modularity for global deployment, the project offers a potential template for future clean industrial hubs seeking to decarbonise hard-to-abate sectors.
