Lämpövarastoihin

Lämpövarastoihin, or thermal storage, refers to technologies and methods used to store thermal energy for later use. This stored heat can be derived from various sources, including solar energy, industrial waste heat, or even electricity generated from renewable sources. The primary purpose of thermal storage is to bridge the gap between the availability of heat and the demand for it, improving energy efficiency and reliability.

There are several types of thermal storage systems. Sensible heat storage involves changing the temperature of a storage medium without changing its phase. Common materials for sensible heat storage include water, rocks, concrete, and molten salts. Latent heat storage utilizes the phase change of a material, such as the melting or freezing of a substance, to store and release large amounts of energy at a relatively constant temperature. Phase change materials (PCMs) are used for this purpose.

Thermal storage systems can be implemented at various scales, from small residential systems to large industrial installations. In buildings, thermal storage can be integrated into heating and cooling systems to reduce peak energy demand and utilize electricity generated during off-peak hours. In industrial processes, waste heat can be captured and stored, reducing the need for primary energy sources. Solar thermal energy systems often incorporate thermal storage to provide heat even when the sun is not shining. The efficient use of lämpövarastoihin is a key component in advancing sustainable energy practices and reducing carbon emissions.
