Advantages and Disadvantages of Pumped Storage Hydropower in Terms of Environmental Impact
Advantages
- Low Greenhouse Gas Emissions: Pumped storage hydropower is noted for having the lowest global warming potential among energy storage technologies. This makes it an environmentally favorable choice for supporting renewable energy systems.
- Closed-Loop Systems: Closed-loop configurations are not connected to naturally flowing water bodies, which can reduce aquatic and terrestrial impacts compared to open-loop systems. This setup offers greater siting flexibility and potentially minimized environmental effects.
- Supports Renewable Energy: By providing a reliable means of energy storage, pumped storage hydropower helps balance the intermittent nature of renewable sources like wind and solar, thus supporting a cleaner energy mix.
Disadvantages
- Construction Impacts: The construction of reservoirs and dams required for pumped storage hydropower can alter ecosystems, affect water flow, and disrupt wildlife habitats. These changes can have significant environmental consequences.
- Geographical Alterations: Creating suitable reservoirs often requires significant alterations to the landscape, which can impact local environments. Finding optimal sites can be challenging due to geographical limitations.
- Closed-Loop Systems Limitations: While closed-loop systems minimize some environmental impacts, they can still affect geology, soils, and groundwater, particularly if they use groundwater for operation.
Overall, while pumped storage hydropower is a valuable component in a renewable energy portfolio due to its low greenhouse gas emissions, it does come with environmental challenges associated with its infrastructure and operational footprint.
