Purchasing Entity: Datang Inner Mongolia Dolun Coal Chemicals Co., Ltd. Procurement Agency: Materials Division of China Datang Group Corporation. The 150,000-kilowatt wind, solar, energy storage and hydrogen production project in Dolun has fully entered market-based operation. On November 20, 2025, China’s first demonstration project integrating green hydrogen with coal chemical processing, namely the 150,000-kilowatt wind, solar, energy storage and hydrogen production integrated demonstration project in Dolun, began full market-based operation, with the collaborative model of “producing hydrogen using green electricity and selling any excess electricity back to the grid” being successfully implemented. The 150,000-kilowatt integrated wind, solar, energy storage and hydrogen production demonstration project in Datang Duolun began construction in November 2023; after 14 months of work, it was completed. It was successfully connected to the power grid on January 17, 2025, and by May 2025 all 17 wind turbines had been connected to the grid, resulting in a 5% increase in the capacity for transmitting clean energy. The total investment in the project is approximately 1.3 billion yuan, and it will be funded and constructed by Datang Duolun Ruiyuan New Energy Co., Ltd., a wholly-owned subsidiary of Datang Group. Datang Group is a state-owned, large-scale energy enterprise under direct central government oversight, and it is one of China’s five major power groups. The new energy project is located near Honghuashan in Luanyuan Town, Tulun County, where a wind farm with a capacity of 120 MW, a photovoltaic power plant with a capacity of 30 MW, and an energy storage system with a capacity of 22.5 MW/45 MWh will be built. Once operational, it will generate 400 million kW•h of electricity per year, with over 20% of that electricity being fed back into the grid. The hydrogen production facility is located to the east of Datang Tuolun Coal Chemical Complex in the Tuolun County Economic Development Zone, covering an area of approximately 46,000 square meters. It is equipped with 14 sets of alkaline water electrolysis systems capable of producing hydrogen at a rate of 1,000 m³/h, as well as hydrogen storage tanks, hydrogen compressors, and chilled water units. The planned annual operating hours are 8,000 hours, with an expected annual hydrogen production volume of 70.59 million cubic meters. This will result in a reduction of 138,800 tons of carbon dioxide emissions; the environmental benefits equivalent to those achieved by 1,400 hectares of mature forest over one year. The green hydrogen it produces is supplied directly via pipelines to the methanol synthesis and polypropylene (PP) production units at the Tonglun Coal Chemical Plant, replacing traditional coal-based gray hydrogen with clean green hydrogen.
