Pumped hydro storage (PHS) facilities have several environmental impacts, which can vary depending on the type of PHS system (open-loop or closed-loop) and its location.
Main Environmental Impacts of Pumped Hydro Storage Facilities
- Alteration of Natural Water Courses and Ecosystems:
- Open-Loop Systems: These are connected to continuously flowing water sources and can disrupt natural water flows, affecting aquatic life and river ecosystems.
- Habitat Disruption:
- The creation of large reservoirs can lead to the displacement of local communities and wildlife, disrupting existing habitats.
- Geological and Groundwater Impacts:
- Closed-loop systems, while not connected to natural water bodies, can impact geology, soils, and groundwater, particularly if they use groundwater for operation.
- Localized Environmental Impacts:
- Closed-loop facilities generally have localized and shorter-duration environmental impacts compared to open-loop systems.
- Land Use and Visual Impact:
- Large areas of land are required for reservoirs, which can lead to changes in landscape aesthetics and potentially affect local ecosystems and biodiversity.
Mitigation Strategies
- Site Selection: Choosing brownfield sites or existing infrastructure like old mines can reduce environmental impacts.
- Design Improvements: Closed-loop systems offer more flexibility in terms of siting and can minimize aquatic impacts.
- Community Involvement: Engaging with local communities can help mitigate social impacts and ensure that projects align with local needs and preferences.
Overall, while PHS facilities have environmental impacts, they can also offer significant benefits in terms of low greenhouse gas emissions, making them a valuable tool for transitioning to renewable energy sources.
