In Germany, the mitigation of CO2 emissions as well as the nuclear power phase-out are important political goals in the course of the sustainable energy transformation process (so-called “Energiewende”). The reduction in fossil- and nuclear-based energy supply has to be compensated by new renewable energies, especially wind power and photovoltaics. Most of the existing studies find that such an increasing contribution from volatile renewables calls for an intensified use of massive energy storage. Conventional technologies for this purpose are pumped-storage hydro power (PSHP) facilities. Typically, these require a storage reservoir on top of a mountain and another one at the bottom. In Germany, unfortunately, suitable sites are quite rare and the constructional measures often have a negative impact on the landscape and the ecosphere, which often induces public resistance. A possible future solution might be the use of underground PSHP (UPSHP) plants, for example, in closed-down mines. This study constitutes an early attempt to model such plants, in order to assess and better understand the economic viability of such underground UPSHP power plants in closed down coal mines. First, we examine the topic from a technical perspective, which is followed by an economic analysis. In the technical assessment, we analyze the feasibility of building an underground reservoir, installing the pressure pipes in the main shaft and equipping the machine cavern with turbines and pumps. In the economic examination, the expected costs for building a UPSHP are calculated. A rough comparison between the costs of a classic and a UPSHP plant is made that also includes the costs of redesigning and reconstructing the underground reservoir. Based on the techno-economic evaluation, we conclude that under favorable conditions the realization of UPSHP plants seems both technically feasible and economically reasonable. More specifically, an extension of a tube system seems the most promising option. We also find that a PSHP plant in a mine shaft is probably slightly more expensive than a conventional one, an outcome that depends strongly on the feasible head. Also, the significant reduction of the adverse impacts on the landscape and local residents could be an advantage. In addition, the number of potential sites might be quite large compared to those for conventional PSHP plants.

This work aims at the economic evaluation of a semi-underground pumped hydro storage power plant erected in an abandoned open pit mine. For the exploratory model-based analysis, we develop and apply both a simple deterministic and a stochastic net present value (NPV) approach, the latter of which uses Monte Carlo simulation to account for revenue uncertainty from electricity price fluctuations. The analytical framework developed is applied to two promising sites in the Rheinland region in Germany, Hambach and Inden, making reasonable parameter value assumptions and considering and ignoring the lengthy duration of lower reservoir flooding. The investor's value-at-risk is computed for alternative performance indicators (the NPV, net cash recovery, profit-to-investment ratio, and specific production costs) to compare the different outcomes in terms of the project's financial risk distribution. Calculations show that a semi-underground pumped hydro storage power plant in an abandoned open pit mine can be constructed at reasonably low investment costs and operated at low specific production costs. However, because the investment has to be made long before the pit lake is (naturally) flooded - a process that for realistic flow rates may take up to 20 years - the project is highly uneconomical and would require substantial subsidies, as compared to a situation where flooding happens immediately.
Pumped Hydro Energy Storage for Hybrid Systems takes a practical approach to present characteristic features, planning and implementation aspects, and techno-economic issues of PHES. It discusses the importance of pumped hydro energy storage and its role in load balancing, peak load shaving, grid stability and hybrid energy systems deployment. The book analyses the architecture and process description of different kinds of PHES, both established and upcoming. Different case studies of pumped hydro energy storage are discussed as well as the advantages and disadvantages of different applications. An essential read for students, researchers and engineers interested in renewable energy, hydropower, and hybrid energy systems. Provides a comprehensive overview of pumped-hydro storage systems and other uses of hydropower in hybrid energy systems Offers a practical approach that includes case studies to present in-depth information on project development and techno-economic challenges, including design, costs, performance and limitations of hybrid pumped hydro systems Explores pathways for hydropower energy storage systems optimization for better electricity generation
