Abstract

Matching the supply of renewable energies with electricity demand, providing cooling services and desalinated water are main challenges faced by desert regions. One solution for the increase in variable renewable sources in the grid is seawater-based pumped hydro storage (PHS) located near mountainous coastlines. However, the widespread adoption of this technology is limited due to the added costs associated with corrosion and safeguarding against seawater intrusion, which can outweigh the advantages of not using freshwater with a lower reservoir. Nevertheless, when contemplating seasonal storage, the use of seawater in PHS plants becomes substantially more compelling. This paper accordingly integrates seasonal pumped hydro storage, seasonal thermal energy storage, and reverse osmosis, so that the same pump and motor is used for storing energy and desalinating seawater. Results presented in this paper are based on the two proposed projects and show that the levelized cost of storage for the projects investigated is 23 and 45 USD/MWh, which is similar to the cost of solar power. In conclusion, integrated seasonal pumped hydro, cooling, and reverse osmosis could be a viable alternative to desert coastal regions.

集成季节性抽水蓄能、冷却和反渗透技术：沙漠沿海地区的解决方案

使可再生能源供应与电力需求相匹配、提供冷却服务和淡化水是沙漠地区面临的主要挑战。电网中可变可再生能源增加的一个解决方案是位于山区海岸线附近的海水抽水蓄能（PHS）。然而，由于腐蚀和防止海水入侵带来的额外成本，这种技术的广泛采用受到了限制。尽管如此，在考虑季节性蓄水时，在 PHS 发电站中使用海水就变得更有吸引力了。因此，本文整合了季节性抽水蓄能、季节性热能储存和反渗透技术，从而使用相同的泵和电机来储存能量和淡化海水。本文基于两个拟议项目得出的结果表明，所调查项目的平准化储能成本分别为 23 美元/兆瓦时和 45 美元/兆瓦时，与太阳能发电成本相近。总之，集成季节性抽水蓄能、冷却和反渗透技术可以成为沙漠沿海地区的可行替代方案。

期刊介绍： Desalination is a scholarly journal that focuses on the field of desalination materials, processes, and associated technologies. It encompasses a wide range of disciplines and aims to publish exceptional papers in this area. The journal invites submissions that explicitly revolve around water desalting and its applications to various sources such as seawater, groundwater, and wastewater. It particularly encourages research on diverse desalination methods including thermal, membrane, sorption, and hybrid processes. By providing a platform for innovative studies, Desalination aims to advance the understanding and development of desalination technologies, promoting sustainable solutions for water scarcity challenges.
