One challenge with renewable forms of energy like wind and solar power is that the power output from such facilities is intermittent. One way to address the problem is to store power from times when it is being produced in excess for use at times when the quantity demanded is high.
This article describes a number of such energy storage options, including ‘Green Power Islands’ along with systems based on pumping water, compressing air, and storing heat in molten salt.
- Batteries for large-scale energy storage
- Baseload solar in Italy
- Proposed pumped hydroelectric storage in Australia
- Pumped and multi-lagoon tidal systems
- Pumped hydroelectric storage in Wales
- Grid technologies to support renewable power
- Peak power, storage, and renewables
- Compressed air for mobile energy storage
