Pumped storage technology has been successfully used for more than 100 years. It is one of the most mature, reliable, and economical technologies in large-scale storage of electrical energy. Abandoned coal mines were changed into pumped storage power stations.
Thermal energy storage (TES) technologies, including sensible (Hasnain, 1998), latent (Sharma et al., 2009) and thermo-chemical (Haider and Werner, 2013), are the strategic and necessary components for the efficient utilization of renewable energy sources and energy conservation.Among these energy storage technologies, STES have been well developed due
The mine water from abandoned coal mines can also be used for the development of Underground Pumped Storage Power (UPSH) or Compressed Air Energy Storage (CAES) plants [18–22]. Large amounts of stored water at stable temperature and low enthalpy are suitable for the supply of sustainable thermal energy in surrounding buildings.
Electricity storage systems are necessary to increase the efficiency of variable renewable energies. Mine water in closed underground coal mines can be used for underground pumped-storage hydropower plants. Subsurface energy storage systems require the excavation of a powerhouse cavern and a network of tunnels as lower water reservoir.
The underground space mined from coal mines as energy storage (CUCAES) can not only effectively utilize the original underground space and surface industrial equipment
Abstract. It is anticipated that utilizing the underground space in abandoned mines to build and operate pumped-storage hydroelectricity (PSH) plants can reduce capital investment and geological constraints. However, there are currently few detailed investigations into techno-economic feasibility except for conceptual studies. In this paper, an underground
Globally, studying the impact of coal mining on groundwater remains challenging. This is because the exploitation of coal resources and the sustainable development of groundwater resources involve economic, social, and environmental aspects. Over the last few decades, the number of publications on groundwater-related studies in coal mining areas has
In the context of sustainable development, revitalising the coal sector is a key challenge. This article examines how five innovative technologies can transform abandoned or in-use coal mines into sustainable energy centres. From solar thermal to compressed air energy storage, these solutions offer a path to a more sustainable future while addressing the decline
At the same time, filling materials is considered to increase the energy of post-peaking phase (non newtonian fluid: energy-absorbing materials), and further slow down the intensity of released
Proposals to build pumped hydro energy storage facilities in the voids left after mining pose risks to taxpayers and the environment. Filling the voids: Pumped hydro proposals could see taxpayers financing mine rehabilitation Many large open-cut coal mining operations in Australia will leave final voids after they finish mining because
The main components of UGES are the shaft, motor and generator, upper and lower storage sites, and mining equipment. The deeper and broader the mineshaft, the more power can be extracted from the plant, and the larger the mine, the higher the plant''s energy storage capacity, according to IIASA. Energy storage in the long-term
Filling and emptying processes during the operation of the turbine-pump are complex due to the presence of two energy storage, hydropower, coal mining, underground water reservoir. 23 1
1. Introduction. Backfilling was born to meet the needs of the mining industry, and it has a history of more than one hundred years. Firstly, the engineering practice of filling emerged in the 1930s, in noncoal mining [1 – 3].According to the development history and characteristics of filling materials, the mine filling technology has experienced a change from
