To begin, we will explore thermal energy storage and how it works. Thermal energy storage is a method of storing thermal energy by heating or cooling a storage medium, such as water, ice, or salt. This stored energy can then be used later to provide heating or cooling when needed. We will discuss how thermal energy storage can be used in various industries, including building cooling systems and power plants, and how it can contribute to energy efficiency and cost savings. Then, we will turn our attention to flywheel storage, which is a kinetic energy storage system that uses a spinning flywheel to store energy. We will explain how flywheel storage works, its advantages over traditional battery storage, and its potential applications in various industries. We will also discuss how flywheel storage can help balance the grid and improve the stability of renewable energy sources.
