In this study, the application and importance of Pumped Hydro Energy Storage (PHES) systems in coastal areas have been evaluated. These systems are considered one of the main solutions to achieve the reduction of greenhouse gas emissions and the increase in the use of renewable energy sources by 2050. Moreover, these systems are environmentally sustainable and can help to better management of renewable energies such as wind and solar power. The main objective of this research is to investigate the use of saltwater for PHES systems in coastal and offshore areas using natural and artificial reservoirs. Hence, the various types of storage systems, materials and methods that used, and the results of economic and environmental assessments have been evaluated. Additionally, low-head PHES systems can be a suitable solution for energy storage in coastal areas with low elevation topography. This study shows that with the proper implementation of PHES systems and the utilization of advanced technologies to prevent corrosion and sedimentation, this potential can be harnessed in Iran's coastal areas, especially in regions such as Assaluyeh, where the sea and mountains are very close, or the islands of Qeshm and Kish, by combining with renewable water and solar energy.
