China-based Envision opens world’s largest green hydrogen, ammonia plant

Green technology developer Envision Energy has commissioned the world’s largest and most advanced green hydrogen and ammonia plant. The Shanghai-based company said the production facility, developed in its hydrogen park in Chifeng, China, is also the first in the world delivering green ammonia at industrial scale and the first of its kind to be fully AI-enabled.

The plant can deliver 320,000 tons of green ammonia annually, with exports set to begin in the fourth quarter of this year, Envision said, adding that the facility represents a major leap forward in industrial decarbonization. By 2028, the output is projected to rise to 1.5 million tons a year.

The project, powered by Envision’s proprietary off-grid renewable energy system, applies innovative energy storage and load flexibility. Surplus green power is stored in the form of liquid nitrogen, and electrolyzers intelligently respond to renewable power swings, dynamically optimizing energy absorption and ammonia production.

By leveraging green ammonia as a stable transportation and storage medium, Envision has unlocked a practical path to scaling hydrogen across heavy industries, reads the press release.

Zhang Lei, Envision’s founder and CEO, noted that scalable, green alternatives are now real and operational, adding that the world cannot reach net zero without green hydrogen.

The first offtake deal is accelerating green ammonia adoption in fertilizer production, chemicals, and shipping

Envision’s project has already concluded a long-term offtake agreement with Marubeni Corporation, one of Japan’s largest trading houses, which will accelerate green ammonia adoption in sectors including fertilizers, chemicals, and shipping.

The company announced that its Chifeng Hydrogen Net Zero Industrial Park is officially the world’s first green ammonia facility to receive the ISCC PLUS certification for green ammonia with a verified greenhouse gas footprint. Envision also noted that its plant has a replicable design that can be quickly deployed globally.
