China awarded approximately 1.7 billion yuan (about 239 million US dollars) in construction contracts for a 1 gigawatt wind-solar-hydrogen project in Damao Banner, Baotou City, in the Inner Mongolia Autonomous Region, industry outlet FuelCellsWorks reported on September 13, 2026. The project, developed by Inner Mongolia Huadian Huayang Hydrogen Energy Technology Co., Ltd., a subsidiary linked to China Huadian Group, is designed to combine 700 megawatts of wind capacity with 300 megawatts of solar capacity to power green hydrogen production, according to project tender documents reported by Shanghai Metals Market (SMM) on July 8, 2026 and an environmental disclosure filing reported by Sina Finance on July 2, 2026, citing the Baotou Municipal Bureau of Ecology and Environment.
The project is being built in the Barun Industrial Park in Damao Banner. Once operational, it is expected to produce approximately 47,000 tonnes of green hydrogen annually, a figure consistent across FuelCellsWorks’ reporting on the contract award and the underlying environmental filing, which stated an annual hydrogen output of about 5.23 x 10^8 normal cubic meters, equivalent to roughly 47,000 tonnes a year. SMM reported a target completion and operation date of August 25, 2027.
Project scope
According to the SMM tender report, the wind component consists of 70 turbines rated at 10 megawatts each, while the solar component uses 710-740 Wp half-cell, double-glass N-type modules. The project also includes a 100 megawatt/200 megawatt-hour lithium iron phosphate (LFP) battery storage station and two 220 kilovolt step-up substations to manage the variable output from wind and solar generation before it reaches the hydrogen production units.
Hydrogen will be produced using 85 alkaline electrolyzers, comprising 83 units rated at 1,000 normal cubic meters per hour, one unit at 2,000 normal cubic meters per hour, and one unit at 3,000 normal cubic meters per hour, per the SMM report. The project includes hydrogen storage capacity of about 650,000 normal cubic meters across 25 spherical tanks of 2,000 cubic meters each.
The construction tender was structured in two sections: a first section covering 617 megawatts of wind, solar, storage and substation works, and a second section covering the remaining 383 megawatts of wind and solar generation along with the hydrogen production station and its substation. SMM reported that the tender process did not accept consortium bids, meaning each contractor bid independently for a full section of the work.
FuelCellsWorks described the project as the largest wind-solar-hydrogen project currently under construction in China. A separate, January 2026 Sina Finance report on an earlier equipment contract for the project’s wind towers described the broader 1 GW first-phase project as “currently China’s largest single green hydrogen project,” with total planned investment of approximately 5.767 billion yuan, a project-wide investment figure distinct from the 1.7 billion yuan construction-contract award reported in September.
Part of Inner Mongolia’s hydrogen build-out
The Damao Banner project reflects Inner Mongolia’s broader push to pair its wind and solar resources with hydrogen production, aiming to convert renewable electricity that might otherwise be curtailed into a storable, transportable fuel. The region has become one of China’s most active bases for wind-solar-hydrogen integration projects as the country works to expand renewable energy consumption alongside its hydrogen economy targets.
Elsewhere in the sector, China previously completed its largest integrated solar-hydrogen-storage project, underscoring how the country continues to scale up combined renewable-and-hydrogen infrastructure as a way of absorbing intermittent wind and solar output. India, meanwhile, has pursued a different application for green hydrogen, flagging off “NaMo Green Rail,” its first hydrogen-powered passenger train.

About the developer
Inner Mongolia Huadian Huayang Hydrogen Energy Technology Co., Ltd. is the project company developing the Damao Banner facility, operating under the Huadian Huayang structure linked to China Huadian Group, one of China’s large state-owned power generation companies. Huadian Huayang has been active in Inner Mongolia’s renewable energy buildout, having separately contracted for wind tower equipment for the project’s earlier construction phases in January 2026. The Damao Banner project forms part of a wider pipeline of wind-solar-hydrogen integration projects across Inner Mongolia’s Baotou region, where Huadian and other state energy companies have been expanding renewable generation capacity to support both electricity supply and green hydrogen production for industrial use.
