英文摘要	As the world transitions from fossil fuels, solar and wind energy have become top renewable and cost-effective alternatives. However, their sporadic nature requires a form of energy storage that is both large-scale and affordable. Pumped Hydro Storage (PHS), despite being the global leader in energy storage, requires substantial amounts of fresh water. This poses a challenge in arid regions, as using seawater would lead to high operational costs. We present a techno-economic analysis of implementing Pumped Hydro Storage (PHS) for storing solar and wind energy, particularly in water-stressed areas. The study first explores the economics and operations of different electricity storage and generation methods, emphasizing the viability of Pumped Hydro Storage (PHS) for large-scale energy storage. It assesses the costs and availability of various electric energy sources, particularly solar and wind, and underscores their seasonal fluctuations. An example of optimizing a PHS system for efficient storage and use of solar and wind energies is presented. An analysis comparing solar and wind energy inputs to total electricity consumption is conducted, and the parameters for PHS sizing are established. Two optimization problems, Design A and Design B, are introduced to minimize seasonal energy storage and exportable energy fraction, respectively. The daily storage capacity considerations for the PHS system are discussed, and a comparison of the annual performances of Design A and Design B is provided. The cost estimates for the current energy mix (with an average LCOE of $42.52/MWh for California) and the proposed 100% solar + wind with PHS energy cluster (Design A results in 9 % annual saving with an average LCOE of $38.69/MWh) are also included. The paper also discusses the water requirements and their cost impact on PHS systems, exploring various options for supplying water to PHS systems in water-scarce areas. For water-stressed countries like Saudi Arabia, seawater desalination using renewable energy is suggested as the best option for implementing PHS, provided there is no environmental damage caused by the brine reject. Other options include harvesting seasonal rainwater and using suitably treated wastewater. The PHS reservoirs should be deep enough (at least 9 m for minimum elevation difference of 150 m) to limit water loss due to evaporation. Finally, the study suggests that the relatively high cost of PHS in the energy mix may be reduced by multipurposing and shared use of the PHS system. PHS systems could serve secondary purposes such as providing high power electricity on demand for Electric Vehicles (EV) supercharging, providing stability to the electrical grid, and serving as tourist attractions. The extra water produced could also be put to multiple uses or sold to increase the revenues.
