Environmental Impact Assessment of the 150,000-kilowatt Wind and Solar Hydrogen Production Integrated Demonstration Project in Dolun by China Datang New Energy Co., Ltd. (Hydrogen Production) Author/Source: Huahua Network Coal Chemicals Date: May 9, 2023 Clicks: 43 On May 7, the first public announcement regarding the environmental impact assessment of this project was made. China Datang Group New Energy Co., Ltd.’s 150,000-kilowatt integrated wind-solar hydrogen production demonstration project in Dolun (hydrogen production). Constructor: Datang Dolun Ruiyuan New Energy Co., Ltd. Location: On the east side of the Datang Dolun coal chemical plant, within the economic development zone of Dolun County, Xilingol League, Inner Mongolia Autonomous Region. Project type: New construction. Planned start date: June 2023. Planned commissioning date: December 2024. Scope of construction: The project involves the installation of 14 alkaline water electrolysis units capable of producing 1,000 Nm3/h of hydrogen each (including associated gas-liquid separation and hydrogen purification equipment); in addition, there will be 2 hydrogen storage tanks with a capacity of 2,000 m3 each, 2 hydrogen compressors, as well as auxiliary chilled water systems. The annual operating time of the project is 8,000 hours; upon reaching full capacity, the annual hydrogen production volume will be 70.59 million Nm3. The hydrogen produced is supplied to the methanol synthesis section of the Datang Dolun coal-to-olefins plant. Datang Duolun Coal Chemical Industry began operating its coal-to-olefins facility in 2011; it produces 1.68 million tons of methanol annually as an intermediate product, while the final products include 460,000 tons of polypropylene per year, along with 240,000 tons of high-purity methanol, 129,500 tons of gasoline, and 66,600 tons of LPG. In February 2023, Datang Group signed an agreement with the Inner Mongolia Autonomous Region; Datang will increase its investments in Inner Mongolia in areas such as new energy, green coal chemical industry, and the production of green hydrogen from renewable electricity. Datang plans to increase its investment in Inner Mongolia by 100 billion yuan over the next five years, and to pursue comprehensive, in-depth, and diversified cooperation with local enterprises in Inner Mongolia Autonomous Region in areas such as wind power, solar energy, green hydrogen production, new types of energy storage, clean coal power generation, coal mining, coal chemical industry, and urban heating. “During the 14th Five-Year Plan period, Datang Zhongxin New Energy Chemical Company accelerated the optimization of its coal chemical industry as well as its green transformation. The projects include the wind and renewable energy substitution project for the coal-fired power plant used by the Duolun coal chemical industry, the renewable energy substitution project for the coal-fired power plant in Keqi County, Chifeng City, operated by Datang, and the 150,000-kilowatt integrated demonstration project for hydrogen production using wind and solar energy in Duolun. Once completed and put into operation, these three projects will help reduce carbon dioxide emissions by approximately 700,000 tons per year, thereby enhancing the green development level and core competitiveness of the coal chemical industry.
