Long duration energy storage allows electricity to be stored for long periods of time (typically over 12 hours) in order to help manage the intermittency of renewable sources like wind and solar. It works by storing excess energy generated by renewables when demand is low and releasing it when demand is high. This helps support a reliable energy grid while allowing renewable sources to contribute a greater share of overall power production. Long duration energy storage can be achieved through various technologies such as pumped hydroelectric, compressed air, flywheels, and batteries.
Here are some example findings from our report:
- Form Energy: Iron-air batteries for storing energy for 100 hours.
- Energy Dome gets €17.5M for deploying their CO2 battery.
- A paper on power-to-methane systems for energy storage in urban energy districts.
