Pumped storage hydropower (PSH), particularly closed-loop systems, has been shown to have the lowest global warming potential (GWP) compared to other energy storage technologies. Studies conducted by the National Renewable Energy Laboratory (NREL) and published in various journals highlight this advantage.
Key Findings
- Lowest GWP: Closed-loop PSH systems have the lowest life cycle greenhouse gas emissions among various energy storage options.
- GWP Range: The global warming potential for PSH spans from approximately 58 to 502 grams of CO2 per kilowatt-hour of stored electricity, though some studies indicate a range up to 530 grams.
- Comparison to Other Technologies: PSH offers significant climate benefits over other energy storage technologies, making it a valuable tool for integrating more renewable energy into the grid.
Overall, pumped storage hydropower is recognized as a critical component in the transition to a net-zero carbon economy due to its low environmental impact and grid resilience capabilities.
