lämmönvarastomateriaali

Lämpövarastomateriaali refers to materials used to store thermal energy. These materials are designed to absorb heat and release it later, playing a crucial role in various energy-saving applications. The primary function of such materials is to buffer temperature fluctuations, allowing for more efficient use of available heat.

Common types of lämmönvarastomateriaali include water, molten salts, and phase change materials (PCMs). Water is a readily available and inexpensive medium for heat storage, often used in solar thermal systems. Molten salts, such as sodium nitrate and potassium nitrate mixtures, can store large amounts of heat at higher temperatures, making them suitable for concentrated solar power plants. Phase change materials are a more advanced category that store and release heat during a change of state, like melting or freezing. This characteristic allows PCMs to store a significant amount of energy within a narrow temperature range.

The selection of a lämmönvarastomateriaali depends on several factors, including the desired storage temperature, the required storage capacity, cost, safety, and lifespan. Applications range from domestic hot water systems and building heating to industrial processes and large-scale energy grids. Effective heat storage can reduce reliance on fossil fuels, decrease greenhouse gas emissions, and improve overall energy system stability and efficiency. Research continues to develop new and improved lämmönvarastomateriaali with enhanced properties for future energy solutions.
