Envision commissions world’s largest green hydrogen/ammonia plant in China

Envision, a global leader in green technology and energy transformation, has officially commissioned the world’s largest and most advanced green hydrogen and ammonia production facility. Powered entirely by the largest off-grid renewable energy system, the plant is also the first of its kind to be fully AI-enabled, achieving real-time optimisation and stability at scale.

Now delivering 320,000 tonnes/year of green ammonia with exports commencing in Q4, the facility represents a major leap forward in clean energy and industrial decarbonisation.

Located in the Chifeng Net Zero Industrial Park — the world’s largest zero-carbon industrial park — this project is a world-first in delivering green ammonia at industrial scale. For the first time at commercial scale, innovative energy storage and load flexibility is applied.

Surplus green power is converted to liquid nitrogen—stored within a dynamic air-separation unit—and electrolysers respond to renewable power swings, optimising energy absorption and ammonia production. By leveraging green ammonia as a stable transport and storage medium, Envision has unlocked a practical path to scaling hydrogen across heavy industries.

The plant is powered by a proprietary AI-integrated off-grid renewable system, featuring advanced wind turbines, grid-forming battery storage, and predictive meteorological modelling. This system dynamically balances wind and solar input with electrolyser and ammonia synthesis demands, ensuring continuous, cost-effective green fuel production without grid reliance.

By 2028, the industrial park is projected to produce 1.5 million tonnes/year of green ammonia, serving as a replicable model for clean industrial hubs worldwide.

The project has already attracted global commercial interest, including a long-term offtake agreement with Marubeni Corporation, one of Japan’s largest trading houses. The partnership will accelerate green ammonia adoption in sectors like fertilisers, chemicals, and shipping.

Designed on a modular, replicable model, Envision says its plant can be quickly deployed globally. It’s not only an engineering triumph but a strategic demonstration of how smart systems, AI, and renewables can come together to reshape global energy infrastructure, it adds.
