Mechanical energy storage systems take advantage of kinetic or gravitational forces to store inputted energy. While the physics of mechanical systems are often quite simple (e.g. spin a flywheel or lift weights up a hill), the technologies that enable the efficient and effective use of these forces are particularly advanced. High-tech materials
A flywheel is a rotating mechanical device that is used to store rotational energy that can be called up instantaneously. At the most basic level, a flywheel contains a spinning mass in its center that is driven by a motor – and when energy is needed, the spinning force drives a device similar to a turbine to produce electricity, slowing the rate of rotation.
Pendulum clock driven by three weights as "gravity battery". An old and simple application is the pendulum clock driven by a weight, which at 1 kg and 1 m travel can store nearly 10 Newton-meter [Nm], Joule [J] or Watt-second [Ws], thus 1/3600 of a Watt-hour [Wh], while a typical Lithium-ion battery 18650 cell [2] can hold about 7 Wh, thus 2500 times more at 1/20 of the

The very high power density of flywheels is based on their mechanical energy and may be somewhat of a theoretical maximum. Conversion to electrical power would have limitations, and ideally a flywheel would convert its energy directly to vehicle motion in an EV, where the high power may be best suited to acceleration and braking.
Thermal Energy Storage: Thermal energy storage systems store excess solar energy in the form of heat. This heat can then be used for space heating, water heating, or other thermal applications. Thermal energy storage systems offer high efficiency and can store energy for extended periods. However, they require proper insulation and are limited
Storing energy can be done in many ways, with the chemical storage method of a battery being one of the most common. Another option is a thermal battery, which basically means making something hot,
The main components of a typical flywheel. A typical system consists of a flywheel supported by rolling-element bearing connected to a motor–generator.The flywheel and sometimes motor–generator may be enclosed in a vacuum chamber to reduce friction and energy loss..
