Envision: 300,000 tons of renewable ammonia capacity online this September
By on May 22, 2025
The Inner Mongolia region has substantial potential for the development of onshore wind and solar energy, and with this the production of electrolytic hydrogen feedstock. In this context, Envision is developing the largest renewable ammonia production facility in China, with a 100% off grid configuration in Chifeng City, East Inner Mongolia. Envision will develop this multiphase project with a final capacity of 5 million tons of green ammonia per year. Envision uses its full-stack in-house technologies to integrate wind power, BESS, electrolysis and ammonia synthesis together to form a competitive solution for the green hydrogen market.
Phase 1 coming online in September 2025

The initial phase of the project started producing ammonia on March 13th 2024, after construction began in April 2023. In this exploratory phase, Envision has so far tested different electrolysis technology types, dynamic ammonia synthesis, and off-grid system configurations. The official phase 1 of the project – with an annual ammonia production capacity of 300,000 tons – is set to come online very soon. Envision can begin to offer large quantities of renewable ammonia to both international and domestic markets from Q4 of 2025. The next phases are another 300,000 tons of annual production capacity (Phase 2), and then an additional 900,000 tons of annual production capacity (Phase 3).

At this week’s World Hydrogen Summit in Rotterdam, Envision announced that the project has been granted the Bureau Veritas Renewable Ammonia Certification, marking it one of the world’s first renewable ammonia facilities to meet Bureau Veritas’s stringent criteria. Envision is also pursuing China’s first ISCC-Plus certification for green liquid ammonia, along with the RFNBO compliance statement. Meanwhile, an offtake agreement with Marubeni has also been secured.
Phase 1 uses electricity transmitted directly from wind and solar farms toward a centralized hydrogen production, nitrogen purification, and ammonia synthesis plant. Envision aims to “debottleneck” electrolytic hydrogen production in future by connecting the facilities through hydrogen pipeline networks. Hydrogen pipeline infrastructure is currently under development in Inner Mongolia, consisting of a main line, two cycle lines, and five branch lines. The main line will connect Ordos City in Mid-West Inner Mongolia and Chifeng City in East Inner Mongolia, and is estimated to be at least 800km long.
Ammonia pipeline for distribution to Jinzhou Port
Renewable ammonia produced from the pilot plant near Chifeng City is currently distributed by trucks for local consumption in China. However, Envision aims to deliver renewable ammonia straight to the Jinzhou Port. Along with developing an ammonia storage terminal and jetty in Jinzhou Port, Envision is also planning a 300km liquid ammonia distribution pipeline, connecting production near Chifeng City to export capabilities in Jinzhou.
