Public Notice on the New Coal Chemical Waste Water to Hydrogen Production Technology Development Project in Yulin; Update Date: 2025-10-27. Recently, a public notice regarding the environmental impact assessment process for the megawatt-scale coal chemical waste water to hydrogen production with simultaneous freshwater generation technology development and industrial demonstration project carried out by the Yulin Zhongke Clean Energy Innovation Institute was released. The construction scope of the project includes the main facilities for this demonstration project, such as hydrothermal oxidation, two-stage reverse osmosis, two-stage resin adsorption, evaporation crystallization, low-temperature evaporation for recovering waste heat from electrolysis, catalytic electrolysis, gas purification, etc., along with the corresponding auxiliary facilities. The procurement process for engineering consultation and design services for this project has been completed: on January 23, 2025, Yulin Zhongke Clean Energy Innovation Institute issued a call for bids for engineering consultation and design services related to a project that aims to produce hydrogen and fresh water from coal chemical wastewater on a megawatt scale, with a budget amount of 901,400 yuan. On May 19, Dalian Chemical Engineering Design Institute Co., Ltd. won the bid for this project at a price of 870,000 yuan. The Yulin Zhongke Clean Energy Innovation Institute (the Yulin branch of the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, abbreviated as “Yulin Innovation Institute”) is an independent local institutional entity approved for registration by the Organizational Structure Committee of the Yulin Municipal Party Committee, as part of the cooperation between the Shaanxi Provincial Government and the Chinese Academy of Sciences in establishing the Yulin Energy Revolution Innovation Demonstration Zone. The Yulin Innovation Institute is located in the Yulin Science and Innovation City. The first phase of the complex covers an area of 109.64 mu, with a total construction area of 86,600 square meters; it includes 4 laboratory buildings and 1 office building. As the core and main component of the Yulin Energy Revolution Innovation Demonstration Zone, the Yulin Innovation Institute focuses on the needs of the zone’s development by establishing four platforms for advanced energy storage, comprehensive hydrogen energy demonstration, integration of hydrogen with coal chemical industry, and the sustainable utilization of carbon dioxide. To date, five key research areas have been established: hydrogen energy storage, downstream coal chemical industries, artificial intelligence, CCUS, and advanced gas production. Efforts are being made to create platforms for scientific research and innovation, with the aim of overcoming the bottlenecks that prevent scientific achievements from progressing from basic research to industrial application. Provincial and ministerial-level as well as municipal-level scientific research and innovation platforms such as the Energy Shaanxi Laboratory, the Key Laboratory of Clean Energy Utilization Technology in Shaanxi Province, and the Zhongke Qinchuangyuan Shangjun Energy Laboratory have been officially established and are under construction. Since its operation began in August 2022, the Yulin Innovation Institute has undertaken 69 research projects in total, resulting in 14 scientific and technological achievements across fields such as hydrogen energy storage, downstream coal chemical processing, and artificial intelligence. Among them, the successfully developed precise denitration technology for magnesium metal smelting flue gas reduces the denitration cost to 80 to 90 yuan per ton of magnesium, saving 70% on equipment investment and 80% on operating costs compared to traditional technologies. In particular, through the coordinated treatment of ammonia-containing wastewater, a daily processing capacity of 20 tons is achieved, creating a circular economy model that utilizes waste to treat other waste, thus achieving a win-win situation in terms of environmental protection and economic benefits.
