Solar heat storage (SHS) solves the fundamental challenge of solar energy: the sun does not always shine. It captures thermal energy from the sun and holds it for later release when energy demand is present, such as during nighttime hours or on cloudy days. The 280 MW plant is designed to provide six hours of energy storage. This process functions similarly to a battery, but instead of storing electrical charges, it holds thermal potential within a storage medium. By storing this heat, solar energy. In a concentrating solar power (CSP) system, the sun's rays are reflected onto a receiver, which creates heat that is used to generate electricity that can be used immediately or stored for later use. This enables CSP systems to be flexible, or dispatchable, options for providing clean, renewable. These systems follow mechanisms that allow for the storage of thermal energy, making it continuously available on demand and not only when the heat source is active and available.
