In the process of coal energy utilization, a large number of greenhouse gases such as carbon dioxide will inevitably be produced. An important way of low-carbon conversion and utilization of coal energy is to collect and reuse these carbon dioxide or seal it underground. Therefore, carbon capture, utilization and sequestration (CCUS) is a new direction of greenhouse gas control, which integrates theoretical basis and technical application research. CCUS team of Low-carbon Energy Research Institute integrates the superior research resources of hydrogeology, chemical engineering, environmental engineering, electric power engineering and other disciplines, and introduces excellent doctors from universities such as Tsinghua University, East China University of Science and Technology, Zhejiang University and China University of Mining and Technology. The chief experts of the team include Professor Terry and Professor Feng Qiyan. Relying on "Jiangsu Key Laboratory of Coal-based CO2 Capture and Geological Storage", the team focused on CO2 storage mechanism, capacity evaluation and storage technology, CO2 capture and purification technology before coal combustion, CO2 resource reuse technology, CO2 geological storage safety monitoring technology, and the economy, management and policy of CO2 capture and storage.
Underground coal gasification R&D team
Underground coal gasification has been studied in China University of Mining and Technology for nearly 30 years. A large number of semi-industrial and industrial experiments have been carried out in Xuzhou, Jiangsu, Tangshan, Hebei, Xinwen, Shandong, Wulanchabu, Inner Mongolia and Huating, Gansu. The new technology of "long passage, large section and two stages" underground guided gasification, the new technology of preparing underground gasification agent by cryogenic air separation oxygen system and the underground gasification technology of coal without well were obtained. In May of 20 10, our school conducted a demonstration test of "Green Low-carbon Mining of Refractory Coal Gasification and Green Coal-electricity Industrialization" in Huating, Gansu Province, and the ignition was successful. The daily gas production is 6.5438+0.6 million standard cubic meters/day, the average calorific value of air gas is 5.45 MJ/ standard cubic meters, and the calorific value of water gas is 654.38+0.26 MJ/ standard cubic meters. In particular, breakthroughs have been made in the measurable controllability of underground gasifier combustion, high quality stability of gas production, smooth airflow and sealing of furnace body. From the point of view of clean coal conversion and utilization, it is a very important way to convert hundreds of millions of tons of economically unrecoverable and large amounts of stranded coal into gas through underground gasification, and then generate electricity or use it in chemical industry. Therefore, the Institute integrates the research resources of mining engineering, safety engineering, geological engineering, chemical engineering and other disciplines, introduces outstanding doctors from Nanjing University, Taiyuan University of Technology and China University of Mining and Technology, and forms a "research and development team for underground coal gasification". The chief expert is Professor Wang Zuotang.

R&D Carbon Footprint Investigation, Monitoring and Assessment Group
Carbon Footprint, also known as "carbon consumption", is a term to describe greenhouse gas (GHG) emissions generated by specific activities or institutions, and it is an international general indicator to evaluate the contribution of greenhouse gases emitted by departments, industries, enterprises and individuals to climate change. Among them, "carbon" is natural resources such as oil, coal and wood. The more "carbon" is consumed, the more carbon dioxide is emitted, and the larger the "carbon footprint" is. Conversely, the smaller the "carbon footprint". Therefore, carbon footprint is a new indicator to measure the environmental impact of carbon dioxide emissions caused by energy consumption.
How to calculate the carbon footprint of coal production scientifically? What should the carbon footprint include? The R&D team of carbon footprint investigation, monitoring and evaluation mainly studies the calculation method of carbon footprint equivalent of surface vegetation destruction and soil disturbance in coal mining; Calculation method of greenhouse gas emissions such as methane in coal mining; Calculation method of carbon footprint in coal processing: carbon footprint monitoring technology, etc. The chief expert of this group is Professor Zhang Shaoliang.

Comprehensive utilization of low concentration gas R&D team integrates superior research resources such as safety engineering, national engineering research center for coal mine gas control, chemical engineering and electric power engineering, and conducts research on key technical issues such as ventilation gas collection, purification, transportation and comprehensive utilization.
