DOI: 10.1115/1.4047406 Corpus ID: 224867454 Techno-Economic Feasibility Analysis of Pumped Storage Hydroelectricity in Abandoned Underground Coal Mines @article{Shang2020TechnoEconomicFA, title={Techno-Economic Feasibility Analysis of Pumped Storage Hydroelectricity in Abandoned Underground Coal Mines},
According to statistics, from 2016 to 2020, 5300 coal mines were closed in China (Fig. 1 b), leaving a large number of underground spaces such as underground roadways, chambers and goafs of working faces (Fig. 1 c), providing sufficient water storage space; ).
On this basis, Xie et al. (2015) estimated that the total amount of water storage and energy generation in abandoned and operating coalmines in China is approximately 7.25 × 10 6 MW·h. Fig. 5 shows the PHS integrated technology concept includes solar and wind power generation; however, these energy sources are random,
Underground roadway + underground roadway. C. Open mode A pumped storage power station is constructed by utilizing the difference in heights between the abandoned open pits. Since the upper and
Rock salt in China is primarily bedded salt, usually composed of many thin salt layers and interlayers (e.g. anhydrite, mudstone, and glauberite). Thus, the feasibility analysis of abandoned salt caverns located in salt beds to be used as Underground Gas Storage (UGS) facilities is full of challenges. In this paper, we introduce the feasibility analysis of
Pumped Storage Hydroelectricity (PSH) is a very important method for energy storage. The cycle of water usage, starting with using excess energy, is of great significance for
New energy power systems have high requirements for peak shaving and energy storage, but China''s current energy storage facilities are seriously insufficient in
China is gradually transforming its coal-based energy supply structure towards sustainable development, resulting in a growing number of abandoned coal
The construction of pumped storage power stations using abandoned mines not only utilizes underground space with no mining value (reduced cost and
Introduction. In China in 2021, coal-power plant created 59.67% of electricity generation, which is the largest source of CO 2 emissions. Coal is the most
As of the end of 2021, China had 36.4 GW of installed pumped storage capacity in operation, with an annual power generation of 3.9 × 10 10 kW·h ( Fig. 1 (a)).
To address the problem of unstable large-scale supply of China''s renewable energy, the proposal and accelerated growth of new power systems has promoted the
In addition, PSHM can achieve water storage, energy storage, power generation, water circulation, renewable energy development and utilization, and so forth. Moreover, it is characterized by a short response time (minutes and seconds) and a long working life (40–60 years), with high energy efficiency (up to 80%).
Technical feasibility of abandoned coal mine goafs used as reservoirs is analyzed. The pumped-hydro energy storage system using one goaf has an efficiency of 82.8%. • For a typical mining area, the effective storage capacity can reach 1.58 ×
The OMAs lack of oversight has allowed mining to proliferate in protected areas. 6. Mining has led to the destruction of ecosystems in the Canaima and Caura National Parks, which overlap with the OMA. Yapacana National Park, which is located outside the OMAs borders, has been harmed indirectly 7.
Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation.
China''s civil electricity price is cheap and the power quality is high, so China''s user-side energy storage is concentrated in commercial use. The scale of energy

Chinese researchers have estimated the potential of underground pumped hydro storage facilities for all the abandoned mines in the Yellow River basin, which crosses nine Chinese provinces and
As an energy basin, the Yellow River basin is a key demonstration area to promote energy system reform in China. There are a large number of abandoned mines
