Why is PCM a good energy storage technology?

PCM offers high energy storage density, surpassed only by chemical storage in hydrogen and methanol, demonstrating its high suitability as a main contributor towards energy efficiency. Figure 1. Comparison of energy storage technologies .

Can nano-PCMS be used for thermal energy storage?

Many studies from the researchers have shown that optimally designed nano-PCMs offer better and efficient thermal performance than those with conventional PCMs. Researchers had identified a significant potential of such nano-PCMs to be used for a wide range of thermal energy storage-based applications in the future.

Are PCMS suitable for thermal management?

The peculiar isothermal nature of PCMs during latent heat transfer makes them suitable for thermal management in various applications like space heating and cooling at constant temperature, solar water heating system, solar desalination, and other building applications.

How much heat does PCM produce?

It was found out that PCM with mass concentration of 60% results in high latent heat of 135 kJ/kg [4, 5]. Buildings form a major portion of energy consumption worldwide (30–40%). Over the last decade, rapid urbanization and new investigation in air-conditioning sector have made buildings highly energy intensive.

What temperature does a PCM melt?

However the most commonly used PCMs use solid-liquid phase transition with melting temperatures in the range of 20–32 °C for maintaining thermal comfort and 32–50 °C for water heating applications in buildings.

What is the optimum operating temperature for a PCM?

To date, numerous potential PCMs have been identified. In literature, authors have listed extensive thermal properties of these reported thermal properties for all known PCMs with melting points between −10 and + 100°C. For the purpose of building applications, however, the most optimum operating temperature range lies between 0 and 35°C.
