Revitalization of Hydro Energy: A New Approach for Storing Solar Energy

Currently, the most suitable technology for storing relatively large amounts of solar energy is hydro energy (pumped storage hydroelectricity (PSH)). Given the problem of intermittent solar energy and the inability to ensure a continuous energy supply to customers throughout the year, this chapter analyzes the integration of solar (photovoltaic or solar thermal) and hydro energy. With all known technologies of storage, only hydro energy can balance seasonal surpluses and shortages of solar energy, and in this way ensure continuous energy supply to consumers throughout the year with low environmental impact. The disadvantages of the site-specific construction of this system can be avoided by using geosynthetics for the construction of reservoirs of PSH in virtually all places where there are height differences. A very important polymer material, geomembranes, which belong to the group of geosynthetics (e.g., geotextiles, geogrids, geonets, geosynthetic clay liners, geopipe, geofoam, geocomposites), can significantly contribute to the further development of PSH technology. The results from the case study show that this concept of using hydro energy for solar energy storage could be flexible in design, construction, and operation.
