In Chifeng, China, Envision Energy launched the full operation of the Chifeng zero‑carbon hydrogen–ammonia industrial park, the world’s largest producer of green hydrogen and ammonia, with an estimated yearly production of 320,000 tons in Phase I. The plan is to scale it up to 5 million tons each year as the long-term ambition.
According to China Daily, the plant started operation of its Phase I last July 8, before the official estimated date of September 2025.
The company started construction of the project in April 2023 and in March 2024 initiated the first small-scale production, and now it’s working on boosting production. The project aims to reduce the carbon footprint of energy production and consumption, amidst global agreements, such as the Paris Agreement, to reduce CO₂ emissions.
“Already operational and scaling fast, this zero-carbon industrial hub is helping to decarbonize some of the world’s hardest-to-abate sectors—steel, chemicals, aviation, and shipping,” commented Envision Energy about the project.
The project received investment of over 40 billion Yuan (around $5.6 billion) in 2022 by the Chifeng City government, as part of a cooperation agreement between Envision Energy Group and the local government. The facility produces hydrogen and ammonia thanks to a completely off-grid electricity generation: 1.43 gigawatts (GW) of wind and solar generation, plus 680 megawatt-hours (MWh) of storage. This guarantees that the local electric system is not affected by the operation of the park.
During the fourth quarter of 2025, the company is expected to be able to sell large amounts of these energy vectors. However, this step is the beginning of an expansion pipeline, expected to double production in 300,000 additional tons per year by 2026-2027 in its Phase II, already in progress. Another 900,000 tons of additional capacity would be added in Phase III of the project, which would be online by 2028, according to the company’s statements.
With its full operation, CO₂ emissions would be reduced by 9.12 million tons each year. Besides the production of these vectors, the company confirmed that this plant will produce green methanol and sustainable aviation fuel (SAF), without specifying the dates.
To date, there are several green hydrogen and ammonia projects under development, planning, and construction around the world. The Australian Renewable Energy Hub is one of the most ambitious, aiming at a yearly production of 8 to 9 million tons of green hydrogen and ammonia, with construction expected to begin by 2026.
