Closed-loop Pumped Storage Hydropower (PSH) systems are particularly beneficial environmentally in several regions due to their low greenhouse gas emissions and ability to support renewable energy integration. Here are some key points about the environmental benefits of closed-loop PSH systems:
- Low Emissions: Studies have shown that closed-loop PSH systems have the lowest life cycle greenhouse gas emissions compared to other energy storage technologies, such as lithium-ion batteries and compressed-air energy storage. This makes them an attractive option for regions transitioning to renewable energy sources.
- Environmental Impact Minimization: Closed-loop systems can minimize environmental impacts by not requiring connection to natural water sources, thus reducing disruptions to aquatic and terrestrial habitats.
- Brownfield Sites: Implementing closed-loop PSH on brownfield sites can reduce the global warming potential by approximately 20% compared to greenfield sites, as this approach avoids disturbances to untouched land.
- Support for Renewable Energy: In regions like the United States, where there is a push for rapid decarbonization and integration of variable renewable energy sources, closed-loop PSH can play a crucial role by providing grid-scale energy storage and resilience.
Examples of potential regions where closed-loop PSH systems could be beneficial include areas with suitable geography and a high demand for renewable energy storage, such as parts of the United States, Europe, and other regions undergoing significant renewable energy transitions. For instance, sites in the United States like those discussed in NREL’s studies can benefit from these systems. However, each location must be evaluated for its specific environmental and social impacts, as highlighted by concerns in areas like Goldendale, Washington.
