New energy power systems have high requirements for peak shaving and energy storage, but China''s current energy storage facilities are seriously insufficient in number and scale.
The quest for carbon neutrality raises challenges in most sectors. In coal mining, overcapacity cutting is the major concern at this time, and the increase in the number of abandoned mine shafts is a pervasive issue. Pumped storage hydropower (PSH) plants built in abandoned mine shafts can convert intermittent electricity into useful energy. However,
This approach should provide comprehensive support for coal-dependent regions, including mining cities, coal workers, and power generation companies. A holistic strategy must integrate energy transition with economic restructuring, worker reskilling, and other essential socio-economic changes to ensure the benefits are equitably distributed
Renewable energy plays a significant role in achieving energy savings and emission reduction. As a sustainable and environmental friendly renewable energy power technology, concentrated solar power (CSP) integrates power generation and energy storage to ensure the smooth operation of the power system. However, the cost of CSP is an obstacle
Pumped storage power stations in the power system have a significant energy saving and carbon reduction effect and are mainly reflected in wind, light, and other new energy grid consumption as well as in enhancing the proportion of clean energy in the power system [11, 12].The use of pumped storage and photovoltaic power, wind power, and other intermittent
The storage situation of China''s underground thermal water resources. The southwest region''s high-temperature geothermal energy has a power generation potential of 7.12 million kilowatts, and its exploitable quantity is equivalent to that of 15.3 million tons of standard coal. regarding the acquisition of geothermal mining rights, the
The share of new energy in China''s energy consumption structure is expanding, posing serious challenges to the national grid''s stability and reliability.As a result, it is critical to construct large-scale reliable energy storage infrastructure and smart microgrids. Based on the spatial resource endowment of abandoned mines'' upper and lower wells and the principle characteristics of the
Fossil fuels now make up less than half of China''s total installed generation capacity, increase new wind capacity by 66 percent, and almost quadruple additions of energy storage. strictly control new coal power, reduce energy and carbon intensity by 2025, increase the share of non-fossil energy sources to 20 percent by 2025 and to 25
