Lämpösäiliöitä

Lämpösäiliöitä, commonly known as thermal energy storage systems, are technologies designed to store thermal energy for later use. This stored energy can be in the form of heat or cold. The primary purpose of a lämpösäiliö is to bridge the gap between the availability of thermal energy and the demand for it, thereby improving efficiency and enabling the use of intermittent energy sources.

There are several types of lämpösäiliöitä, categorized by their storage medium and operating temperature. Sensible heat storage systems store thermal energy by changing the temperature of a storage material, such as water, rocks, or molten salts. Latent heat storage systems utilize the phase change of a material, like phase change materials (PCMs), to store and release large amounts of energy at a nearly constant temperature. Thermochemical storage systems involve reversible chemical reactions to store and release heat.

Applications for lämpösäiliöitä are diverse. They are used in buildings for space heating and cooling, industrial processes to capture waste heat, and in solar thermal energy systems to store solar energy for use when the sun is not shining. Thermal energy storage can also play a crucial role in grid stability by storing excess electricity generated from renewable sources and converting it to heat or cold for later use. This helps to balance supply and demand and reduce reliance on fossil fuels. The efficiency and cost-effectiveness of lämpösäiliöitä are continually being improved through ongoing research and development.
