Envision Energy has commissioned what it says is the world’s largest green hydrogen and ammonia production facility, powered by an off-grid renewable energy system.
Located at the Chifeng Net Zero Industrial Park in Inner Mongolia, an autonomous region of China, the new facility is currently producing 320,000 tonnes of green ammonia annually, with exports set to commence in the fourth quarter of this year.
By 2028, plans are to ramp up this output to 1.5 million tonnes per year.
At the facility, surplus green energy is converted to liquid nitrogen – stored within a dynamic air-separation unit – while electrolysers intelligently respond to renewable power swings, optimising energy absorption and ammonia production.
An AI-integrated renewable energy system, which incorporates wind turbines, grid-forming battery storage, and predictive meteorological modelling, balances wind and solar input with electrolyser and ammonia synthesis demands, ensuring the facility can operate independently of the grid.
‘Scalable, green alternatives’
“This is more than a technological milestone,” commented Lei Zhang, Envision’s founder and CEO. “Scalable, green alternatives are now real and operational. We can’t get to net zero without green hydrogen, and we can’t afford to wait. This is the blueprint for a clean energy future.”
The facility has signed a long-term offtake agreement with Japan’s Marubeni Corporation, one of Japan’s largest trading houses, which will accelerate green ammonia adoption in sectors like fertilisers, chemicals, and shipping, Envision noted.
The facility has also been awarded the Bureau Veritas Renewable Ammonia Certification for meeting sustainability and safety standards.
‘Designed on a modular, replicable model, Envision’s plant can be quickly deployed globally,’ the company noted. ‘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.’ Read more here.
