Envision Commissions World's Largest Off-Grid Green Hydrogen and Ammonia Plant in China, Signaling Major Industry Shift
Key Insights
Envision has commissioned the world's largest green hydrogen and ammonia plant in Chifeng, China, powered entirely by an off-grid renewable energy system.
The facility utilizes advanced AI for real-time optimization, producing 320,000 tonnes of green ammonia annually from 500MW of electrolysis capacity.
Japan's Marubeni Corporation has signed a long-term offtake agreement for the green ammonia, targeting use in fertilizers, chemicals, and shipping.
This project serves as a blueprint for large-scale industrial decarbonization, with Envision aiming to expand its capacity to over 2.5GW by 2028.
Envision, the Chinese wind turbine and energy technology giant, has successfully commissioned what it describes as the world’s largest and most advanced green hydrogen and ammonia plant in Chifeng, China. The facility, located within the Chifeng Net Zero Industrial Park, commenced operations on July 10, 2025, and is powered entirely by an off-grid renewable energy system, marking a significant milestone in industrial decarbonization.
The Chifeng plant currently boasts 500 megawatts (MW) of electrolysis capacity, enabling the annual production of 320,000 tonnes of green ammonia. This substantial output positions the facility as a critical player in the burgeoning global green fuels market. The project integrates advanced artificial intelligence (AI) systems to provide real-time optimization and enhance operational stability, a key factor in maximizing efficiency and reliability for such large-scale renewable energy-driven processes.
The strategic importance of this project is further underscored by its immediate market impact. Envision plans to begin exporting green ammonia from the Chifeng site in the fourth quarter of this year. Notably, Japan’s Marubeni Corporation has already secured a long-term offtake agreement for a portion of the plant’s output. This green ammonia is slated for diverse applications, including the production of fertilizers, various chemicals, and as a clean fuel for the shipping industry, highlighting the compound’s versatility in reducing carbon footprints across multiple sectors.
This initiative serves as a powerful demonstration of the potential for integrated, off-grid renewable energy solutions to support large-scale industrial processes. The ability to produce green hydrogen and ammonia independently of the conventional grid not only enhances energy security but also offers a scalable model for regions aiming for energy self-sufficiency and deep decarbonization. Envision has articulated ambitious plans to expand its green hydrogen and ammonia capacity, targeting over 2.5 gigawatts (GW) by 2028, signaling a strong commitment to scaling up this transformative technology. The Chifeng plant’s operational success and the secured international offtake agreement are expected to catalyze further investment and development in similar green energy hubs globally, accelerating the transition away from fossil fuel-dependent industrial practices.
