On January 29, the construction of the 2×600,000-kilowatt coal underground gasification power generation project for the Yankuang Luxi Power Generation Project officially commenced. This is the first large-scale underground coal gasification power generation project in Shandong Province, and it represents another innovation in the green extraction and utilization of coal. The total investment in the Yankuang Luxi power generation project is approximately 5.6 billion yuan. The construction scale consists of 2×600,000-kilowatt-class high-efficiency ultra-supercritical coal-fired condensing generating units. Additionally, a dedicated railway line for coal transport, as well as projects for generating electricity through coal gasification underground, will be built. Desulfurization and denitrification facilities, along with related production, auxiliary production, and supporting infrastructure, will also be established. Unit 1 is scheduled to come online in February 2021, while Unit 2 is scheduled to come online in May 2021. Industry experts say that underground coal gasification technology offers good economic and environmental benefits. Shifting from \"physical coal mining\" to \"chemical coal mining\" will **improve the utilization rate and efficiency of coal resources, and it represents an important area of research and development in China’s clean coal technology. It is understood that coal gasification is one of the important forms of coal conversion, playing a pivotal role in various production processes. Coal in-situ gasification is a technology that involves the controlled combustion and gasification of coal located underground. Through thermal and chemical processes applied to the coal, usable gaseous energy is generated; the useful components are extracted while waste materials such as coal gangue and carbon dioxide remain underground. This approach reduces carbon emissions and prevents safety accidents, At the same time it also enables the production of chemical products such as hydrogen, methane, and methanol. Coal underground gasification for power generation is a new technology that integrates multiple processes such as shaft construction, coal mining, gasification, and power generation to develop clean energy and chemical raw materials. It boasts advantages such as good safety, low investment, high efficiency, and minimal pollution, and is regarded as the second-generation coal mining method. Coal in-situ gasification technology can not only recover coal resources left behind in mines, but also be used to extract thin coal seams, deep coal seams, coal seams under roads, buildings, and railways, as well as coal seams with high sulfur, high ash, and high methane content – seams that are difficult to exploit using conventional mining methods or for which such extraction is not economically or safely viable. This technology allows for a significant increase in the amount of coal that can be extracted. Depending on the composition of the gas and the application conditions, underground gasification gas can be used for combined-cycle power generation, the production of pure hydrogen, as well as as a raw material gas for the chemical industry, an industrial fuel gas, and urban household gas. In particular, after underground gasification, a combustible hydrogen-rich gas is produced; through various purification and separation processes on the surface, this gas can be divided into two parts: one part is compressed hydrogen, and the other part is pure carbon dioxide. Hydrogen can be used as an energy source to generate electricity in fuel cells, while carbon dioxide can be captured and stored underground. Previously, Yankuang Group, Shandong Heavy Industry, and Guohui Investment jointly established the Shandong Hydrogen Energy and Fuel Cell Industry Alliance, focusing on the hydrogen energy sector; this initiative serves as a perfect illustration of Shandong’s commitment to advancing hydrogen energy technology. Li Xiyong, Secretary of the Party Committee and Chairman of Yankuang Group, said: “Accelerating the integrated development of coal and power generation is an important measure to promote the clean and efficient development of coal-based power generation.” ”It is reported that Yankuang Group began investing in the power industry in the 1980s; currently, its total installed capacity is 784,000 kilowatts, with an annual electricity generation volume of 4.5 billion kilowatt-hours. Earlier, Yankuang Group signed a Framework Agreement on the Transfer of the Luxi Prison Power Generation Project with the Shandong Provincial Prison Administration Bureau, thereby obtaining control rights over the Luxi power generation project. It is understood that the 2×600,000-kilowatt coal underground gasification power generation project of Luxi Power Generation Co., Ltd. is located in the industrial park of Taiping Town, Zoucheng City, and its construction was approved by the Shandong Provincial Development and Reform Commission in 2016. Once completed and put into operation, this project will be able to generate 6 billion kWh of electricity per year, as well as provide 100 tons of steam per hour for industrial use. It will serve a heating area of 23 million square meters in the eastern part of Jining City, thus becoming a key heat supply source for centralized heating in this city as planned. Yankuang Group stated that it will strive to turn the Luxi power generation project into a world-class, technologically advanced, environmentally friendly and efficient factory of a garden-like design, making it a model project, an exemplary project and a high-quality project for the transformation of old and new growth drivers in our province.
