China connects its first large-scale flywheel storage project to grid

Flywheel energy storage technology is a form of mechanical energy storage that works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as kinetic energy.

Energy storage

What is grid-scale storage? Grid-scale storage refers to technologies connected to the power grid that can store energy and then supply it back to the grid at a more advantageous time – for example, at night, when no solar power is available, or during a weather event that disrupts electricity generation.
