- Flywheel Energy Storage: Flywheels store energy in the form of kinetic energy by spinning a rotor at high speed. They offer fast response times and high power density, making them suitable for grid stabilization applications.
Thermal Storage
Thermal storage technologies store energy in the form of heat or cold.
- Sensible Heat Storage: Sensible heat storage involves storing energy by raising the temperature of a storage medium, such as water, rocks, or molten salt.
- Latent Heat Storage: Latent heat storage involves storing energy by changing the phase of a storage medium, such as melting ice or vaporizing water.
- Thermochemical Storage: Thermochemical storage involves storing energy in the form of chemical bonds.
Hydrogen Storage
Hydrogen storage involves storing energy in the form of hydrogen gas or liquid. Hydrogen can be used as a fuel for transportation, power generation, and industrial processes.
