Flywheel energy storages are commercially available (TRL 9) but have not yet experienced large-scale commercialisation due to their cost disadvantages in comparison with battery storages (higher investment, lower energy density).
Flywheel energy storage systems (FESS) are considered environmentally friendly short-term energy storage solutions due to their capacity for rapid and efficient energy storage and release, high power density, and long-term lifespan. These attributes make FESS suitable for integration into power systems in a wide range of applications.
Moreover, flywheel energy storage system array (FESA) is a potential and promising alternative to other forms of ESS in power system applications for improving power system efficiency, stability and security . However, control systems of PV-FESS, WT-FESS and FESA are crucial to guarantee the FESS performance.
Home » Clean Technology » China Connects World's Largest Flywheel Energy Storage Project to the Grid China has connected its first large-scale, grid-connected flywheel energy storage system to the power grid in Changzhi, Shanxi Province.
The use of new materials and compact designs will increase the specific energy and energy density to make flywheels more competitive to batteries. Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel's secondary functionality apart from energy storage.
Flywheel storage technology offers several advantages over conventional energy storage methods. It has a higher energy density and longer lifespan compared to lithium-ion batteries. Moreover, flywheels have a lower environmental impact since they do not use toxic chemicals and can maintain operational efficiency for 20-30 years.
Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm. Electrical energy is thus converted to kinetic energy for storage. For discharging, the motor acts as a generator, braking the rotor to produce electricity.

Pumped storage hydropower is the world's largest battery technology, with a global installed capacity of nearly 200 GW – this accounts for over 94% of the world's long duration energy storage capacity, well ahead of lithium-ion and other battery types. Water in a PSH system can be reused multiple times, making it a rechargeable water battery.
Pumped storage might be superseded by flow batteries, which use liquid electrolytes in large tanks, or by novel battery chemistries such as iron-air, or by thermal storage in molten salt or hot rocks. Some of these schemes may turn out to be cheaper and more flexible. A few even rely, as pumped storage does, on gravity.
Water in a PSH system can be reused multiple times, making it a rechargeable water battery. PSH systems typically have large capacities and can run for long durations. This is crucial because they can provide reliable power when demand is high.
