Wedoany.com Report, On March 16, 2026, China Datang Inner Mongolia Duolun Coal Chemical Co., Ltd. issued a procurement inquiry for technical services related to the feasibility study and green methanol certification consultation for the Zhongxin Nenghua Duolun Coal Chemical Project, which involves biomass co-firing, green power coupling, and green methanol production. The bid submission deadline is 17:00 on March 19, 2026, with validity until June 14, 2026. The procurement is being handled by the Datang Group Materials Branch. 
This green methanol project aims to promote the low-carbon transformation of the coal chemical industry through biomass co-firing and green power coupling technology. Previously, Datang Group successfully operated China's first green hydrogen-coupled coal chemical demonstration project in Duolun County, Inner Mongolia—the Datang Duolun 150,000 kW Wind-Solar-Storage-Hydrogen Integration Demonstration Project. This project entered full-scale market operation on November 20, 2025, achieving a synergistic model of "green power for hydrogen production + surplus electricity grid connection."
The Datang Duolun 150,000 kW Wind-Solar-Storage-Hydrogen Project has a total investment of approximately 1.3 billion yuan and was constructed by Datang Duolun Ruiyuan New Energy Co., Ltd., a wholly-owned subsidiary of Datang Group. The project commenced construction in November 2023 and was successfully connected to the grid in January 2025. It includes a 120 MW wind farm, a 30 MW photovoltaic power station, and an energy storage system, with an annual power generation capacity of 400 million kWh, of which 20% is surplus electricity fed into the grid.
The hydrogen production facility is located in the Duolun County Economic Development Zone and is equipped with 14 sets of alkaline water electrolysis hydrogen production units. It is expected to produce 70.59 million cubic meters of hydrogen annually, reducing carbon dioxide emissions by 138,800 tons, equivalent to the annual carbon absorption of 1,400 hectares of forest. The green hydrogen is supplied via pipeline for methanol and polypropylene production in the coal chemical process, replacing traditional coal-based gray hydrogen and supporting green methanol production.
