Against the backdrop of accelerated pursuit of the dual carbon goals and the development of new power systems, energy storage has evolved from an optional solution into an indispensable necessity.
Among diverse technical routes, Yuankong maglev flywheel energy storage stands out with its pure physical working mechanism, millisecond-level response speed and tens of millions of charge-discharge cycles. It is playing an irreplaceable role in core scenarios including grid frequency regulation, industrial energy conservation and data center emergency power supply, serving as a leading practitioner of this cutting-edge technology.
Its essence lies in the instantaneous conversion between electric energy and kinetic energy without any chemical reactions. When power is input, dual-direction motors drive flywheel rotors to spin at high speed in a vacuum chamber to store electricity as kinetic energy. When power output is needed, the decelerating flywheel drives generators to convert kinetic energy back into electric energy, relying purely on physical motion.
Adopting high-strength and low-density carbon fiber composite rotors, the system operates stably at tens of thousands of revolutions per minute in vacuum environments. Equipped with maglev bearing technology that minimizes friction loss, it achieves an energy conversion efficiency of over 93% and realizes millisecond-level charge-discharge response.
Derived from dual-purpose flywheel technologies for satellite attitude control and energy storage, this core technology won the First Prize of National Technological Invention and owns seven national invention patents.
Compared with electrochemical energy storage, it boasts three prominent strengths:
Tens of millions of cycles with zero performance degradation throughout service lifeIt supports over ten million charge-discharge cycles with a design lifespan of more than 20 years, maintaining rated power capacity permanently without capacity attenuation. It requires no intermediate equipment replacement and ensures predictable full-lifecycle asset value.
Absolute operational safety and eco-friendlinessFree from chemical reactions, thermal runaway risks, explosion hazards and hazardous waste disposal issues, it realizes zero pollution covering production, operation and decommissioning.
Space-saving layout and flexible capacity expansionIt only occupies around one-third of the land area required by lithium batteries of the same power rating, presenting outstanding advantages in densely loaded areas such as data centers and industrial parks.
Its one-time investment locks long-term operation and maintenance costs. It needs no complex temperature control systems or regular battery replacement, keeping daily operating expenses stable long-term.
With the growing installed capacity of wind and solar power, grid frequency fluctuations become more frequent and intense. Traditional thermal power units only feature second-level regulation speed, failing to match the millisecond-level volatility of renewable energy.
Yuankong maglev flywheel energy storage completes power compensation instantly before grid frequency deviation occurs, acting as the primary safeguard for grid stability. It can independently conduct primary and secondary frequency regulation, or form hybrid energy storage systems with electrochemical batteries. Flywheels undertake high-frequency short-duration power regulation while batteries provide sustained energy support. This combination improves frequency regulation accuracy and extends battery service life effectively.
In rail transit, it recycles braking kinetic energy of running trains to cut station energy consumption significantly.
It also delivers reliable instantaneous power supply for petrochemical plants, 5G base stations and computing centers with strict power stability requirements, ensuring continuous operation of key facilities, lowering maintenance costs and eliminating environmental concerns.
Its application scope has further expanded to stable power supply for data centers, peak-shaving power utilization in industrial and commercial parks, and flexibility renovation of thermal power plants.
The rapid growth of renewable energy installation has sharply increased market demand for fast grid regulation capacity. Featuring millisecond response and ultra-long cycle life, Yuankong flywheel energy storage has become a vital fast-regulation resource for modern power grids.
It collaborates with pumped hydro storage and electrochemical energy storage to build a diversified three-dimensional energy storage network. Pumped hydro undertakes large-scale long-duration regulation, electrochemical energy storage realizes multi-hour energy shifting, and flywheel energy storage provides instant millisecond power support, jointly guaranteeing safe and stable grid operation.
The National Energy Administration has listed flywheel energy storage as a key development direction for new energy storage and defined it as an independent technical route in industrial standards. Local governments have issued supportive policies to boost industrial development.
Yuankong has established a complete industrial layout consisting of one operation center and two manufacturing bases: the Hefei Operation Center oversees business expansion, supported by the CRRC OEM Base in Zhuzhou and the Industry 4.0 Intelligent Manufacturing Base in Chaohu. Strategic cooperation has been built with CRRC Group, State Grid Anhui Comprehensive Energy Service Company and other leading enterprises to supply core equipment and technical services for thermal power plant renovation and independent energy storage frequency regulation power stations.
As the energy revolution goes deeper, the evaluation standard of energy storage is shifting from initial installation cost per kilowatt-hour to full-lifecycle power cost and comprehensive economic benefits.
With millisecond response speed, tens of millions of service cycles, zero capacity decay and fixed long-term operating costs, Yuankong maglev flywheel energy storage has built irreplaceable competitive edges in grid frequency regulation, industrial energy conservation and data center backup power supply.
It is no longer a futuristic technology, but a mature asset ready for large-scale commercial application. The flywheels keep spinning, and Yuankong Energy Storage & Charging keeps moving forward steadily.
