The global flywheel energy storage systems (FESS) market was estimated at USD 461.11 billion in 2024 and is projected to reach USD 631.81 billion by 2030, growing at a CAGR of 5.2% from 2025 to 2030. This growth is being driven by a combination of factors that are reshaping the global energy landscape.

One of the primary drivers is the rising demand for reliable and clean energy sources, as industries and governments around the world continue to seek alternatives to fossil fuels. This trend is further reinforced by increasing regulatory support for clean power generation, which is encouraging the adoption of advanced energy storage technologies.

The ability of flywheel systems to deliver uninterrupted power supply (UPS) solutions makes them particularly valuable in regions with unstable grid infrastructure, including many developing countries and remote locations. By ensuring consistent power delivery, flywheels are emerging as a dependable choice for critical applications where power interruptions can have significant consequences.

Another important growth factor is the integration of flywheel energy storage with renewable energy sources such as wind and solar. Flywheels play a crucial role in addressing the variability of renewables, helping to stabilize grids and ensure smoother energy distribution. Their long operational lifespan, high energy efficiency, and low maintenance needs compared to conventional battery storage technologies add to their appeal, making them cost-effective and sustainable over the long term.

As a result, flywheel systems are finding increasing applications in data centers, distributed energy generation, and industrial facilities, where reliability, durability, and efficiency are critical. Together, these advantages position FESS as a vital technology supporting the transition toward a more resilient, sustainable, and low-carbon energy future.
