Flywheel energy storage (FES) is no longer a niche concept—especially in Finland, where innovation meets practicality. Unlike traditional batteries, flywheels store kinetic energy in a rotating mass, offering rapid response times and near-zero degradation.
By combining battery technologies with flywheels or other storage solutions, the strengths of each technology can be leveraged to create a more balanced and resilient energy storage system.
Flywheels are one of the world''s oldest forms of energy storage, but they could also be the future. This article examines flywheel technology, its benefits, and the research from Graz University of Technology.
In this paper, state-of-the-art and future opportunities for flywheel energy storage systems are reviewed. The FESS technology is an interdisciplinary, complex subject that involves electrical, mechanical, magnetic subsystems.

Flywheel energy storage systems offer a durable, efficient, and environmentally friendly alternative to batteries, particularly in applications that require rapid response times and short-duration storage. For displacing solar power from midday to late afternoon and evening, flywheels provide a promising solution.
This mismatch between supply and demand necessitates effective energy storage solutions. While batteries have been the traditional method, flywheel energy storage systems (FESS) are emerging as an innovative and potentially superior alternative, particularly in applications like time-shifting solar power.
A project team from Graz University of Technology (TU Graz) recently developed a prototype flywheel storage system that can store electrical energy and provide fast charging capabilities. Flywheels are considered one of the world’s oldest forms of energy storage, yet they are still relevant today.
Flywheel systems are ideal for this form of energy time-shifting. Here’s why: Solar power generation peaks in the middle of the day, but energy demand peaks in the late afternoon and early evening. Flywheels can quickly absorb excess solar energy during the day and rapidly discharge it as demand increases.
Modern flywheels can achieve round-trip efficiencies of 85–90%, comparable to advanced battery systems. Moreover, flywheels can store and release energy with minimal losses, particularly when used for short-duration storage (on the order of minutes to a few hours).
Flywheels can charge and discharge energy rapidly, making them particularly well-suited for applications that require high power density and fast response times, such as grid stabilization and frequency regulation. In contrast, batteries, especially lithium-ion ones, may degrade over time if subjected to frequent and rapid charge-discharge cycles.
