China firm launches world-largest green hydrogen and ammonia plant

A Shanghai-based company, Envision Energy, has launched what it claims to be the world’s largest and most advanced green hydrogen and ammonia production facility in Chifeng, China. Powered entirely by the largest off-grid renewable energy system, the plant integrates wind, solar, and energy storage to produce green ammonia with an initial annual target of 300,000 tons, scaling up to 1.5 million tons by 2028. The facility is notable for being fully AI-enabled, allowing real-time optimization and stability at industrial scale, and is located within the Chifeng Net Zero Industrial Park, the world’s largest zero-carbon industrial park. This project represents a significant advancement in clean energy and industrial decarbonization, employing innovative energy storage and load flexibility technologies such as converting surplus green power to liquid nitrogen and dynamically adjusting electrolyzer operations based on renewable power availability. Envision positions the plant as a modular, replicable model for clean industrial hubs globally, emphasizing its strategic role in achieving net-zero
