As one of China's first national pilot hydrogen projects approved by the National Energy Administration, the project has a total investment of 3.5 billion yuan ($500 million), a hydrogen production capacity of 48,000 Nm³/h, and 12 spherical hydrogen storage tanks, each with a capacity of 1,875 m³. The project is powered by a 500 MW wind farm and a 5 MW off-grid solar-hydrogen production system. It also features a downstream chemical facility with an annual output of 150,000 metric tons of synthetic ammonia, as well as a 30 MW pure hydrogen gas turbine for hydrogen energy storage.

The project is expected to generate 1.4 billion kilowatt-hours of electricity annually, producing 20,000 tons of green hydrogen and 150,000 tons of green ammonia. This will save about 490,000 tons of standard coal, with renewable energy utilization exceeding 80 percent.

Aligned with Ordos' energy transition and industrial development goals, the project utilizes local renewable resources to produce hydrogen and supply it to downstream chemical sectors, forming an integrated green energy supply chain.

The project's supporting power supply has already been connected, and the 30-megawatt hydrogen turbine is operating steadily. The electricity generated will not only underpin the production of green hydrogen and ammonia, but also support Ordos' efforts to build a new power system dominated by renewable energy.
