Abstract - This study gives a critical review of flywheel energy storage systems and their feasibility in various applications. Flywheel energy storage systems have gained increased popularity as a method of environmentally friendly energy storage.
A flywheel-storage power system uses a flywheel for grid energy storage, (see Flywheel energy storage) and can be a comparatively small storage facility with a peak power of up to 20 MW. It typically is used to stabilize to some degree power grids, to help them stay on the grid frequency, and to serve as a short-term compensation storage.
Source: Endesa, S.A.U. Another significant project is the installation of a flywheel energy storage system by Red Eléctrica de España (the transmission system operator (TSO) of Spain) in the Mácher 66 kV substation, located in the municipality of Tías on Lanzarote (Canary Islands).
The clean energy projects at the base are planned to have an installed capacity of 6 million kW, which includes 4.5 million kW of wind power and 1.5 million kW of solar power. Construction of the supporting energy storage facilities is also included.
It was constructed in conjunction with the CHN Energy’s East Ningxia 1.5 GW Composite Photovoltaic Base Project, with a planned total capacity of 200 MW/400 MWh.
All projects at the base are scheduled to be put into operation within China's 14th Five-Year Plan (2021-25) period. Once operational, the base is expected to export 24 billion kWh of power annually to East China’s Shandong Province through the ultra-high-voltage power transmission line.
Once operational, the base is expected to generate more than 14 billion kWh of clean power, equaling that produced by burning 4.2 million tons of standard coal and a reduction of 11 million tons of carbon dioxide.

Total wind energy potential: According to the World Bank estimation, the technical wind offshore power potential exceeds 70 GW, which is 10 times the capacity of all power plants in Turkmenistan in 2022. Onshore Wind Potential: 10 GW, 222W/m2 at a height of 50m.
To support these initiatives, Turkmenistan is improving energy interconnectivity with neighbors and expanding its transmission network into Europe and South Asia. Key projects include the Trans-Caspian Pipeline (TCP) and the Turkmenistan-Afghanistan-Pakistan-India (TAPI) gas pipeline.
Average Theoretical Solar Potential: 4.4 kWh/m2, roughly 655 GW of additional capacity. Potential: Turkmenistan, with the world’s fourth-largest natural gas reserves, is strategically positioned for hydrogen energy development, as 68% of global hydrogen production is derived from natural gas, making it the most cost-effective method.
The low-carbon energy transition in Turkmenistan is stalled due to the dominance of fossil fuels, which crowd out low-carbon alternatives. Key factors include: Abundant fossil fuel reserves lead to low-cost energy production that meets domestic demand, limiting the market for low-carbon options.
