lämmönvarastoihin

Lämpövarastoihin, or thermal energy storage systems, are technologies designed to store thermal energy for later use. This stored heat can be used for heating or cooling purposes. The primary goal of thermal energy storage is to balance the supply and demand of thermal energy, which can fluctuate significantly due to factors like intermittent renewable energy sources or changing weather conditions.

There are several types of thermal energy storage systems. Sensible heat storage systems store heat by changing the temperature of a storage medium, such as water, rocks, or concrete. Latent heat storage systems utilize the phase change of a material, like a phase change material (PCM), to store and release heat. This phase change absorbs or releases a significant amount of energy at a nearly constant temperature. Thermochemical energy storage systems involve reversible chemical reactions to store and release thermal energy.

Applications for thermal energy storage are diverse. They are commonly used in buildings for space heating and cooling, often coupled with solar thermal collectors or heat pumps. Industrial processes can benefit from thermal energy storage to manage waste heat or to meet fluctuating process heat demands. Furthermore, thermal energy storage plays a crucial role in grid-scale energy management, helping to stabilize the electricity grid by storing excess energy generated from renewable sources and releasing it when needed. The efficiency and effectiveness of these systems depend on factors such as the storage medium, the storage duration, and the specific application requirements.
