Closed-loop pumped storage hydropower (PSH) is generally beneficial environmentally compared to open-loop systems because it minimizes aquatic and terrestrial impacts by not being continuously connected to a naturally flowing water body. While specific regional advantages are not detailed extensively, the following points highlight why certain areas might benefit more from closed-loop PSH:
- Off-Stream Locations: Closed-loop systems offer greater siting flexibility, allowing them to be located “off-stream.” This reduces the impact on rivers and streams, making them suitable for regions with sensitive aquatic ecosystems.
- Brownfield Sites: Using brownfield sites, such as former mining areas, can further reduce environmental impacts. These sites are particularly beneficial as they require less new land use and can help in the rehabilitation of existing disturbed areas, reducing the overall greenhouse gas emissions by about 20% compared to greenfield developments.
- Sensitive Environmental Areas: Regions with high environmental sensitivity, such as areas with protected species or unique ecosystems, might benefit more from closed-loop PSH. These systems can minimize the disturbance to local wildlife and ecosystems, making them a preferable choice in such areas.
- Areas with High Renewable Energy Integration: Regions aiming to integrate more variable renewable energy sources (like solar and wind) can benefit from closed-loop PSH’s ability to provide grid-scale energy storage. This capability helps stabilize the grid and ensure a smoother transition to renewable energy sources.
Overall, regions that prioritize environmental conservation, have sensitive ecosystems, or are looking to integrate more renewable energy into their grids can find closed-loop PSH particularly beneficial.
