Why Cooling Systems Matter for Flywheel Energy Storage

Flywheel energy storage systems are gaining traction as a sustainable solution for industries requiring rapid energy discharge and high cycle efficiency. However, their performance hinges on one often-overlooked component: the cooling system. Without effective thermal management, friction-induced heat can reduce energy density, accelerate wear, and even cause system failure. Let's explore how advanced cooling technologies are shaping this industry.
