| Abstract |
This paper reports development trends of latent heat energy storage technology, one of thermal energy storage technologies, using phase change materials. Part 1 presents policy plans and market size associated with thermal energy storage, evaluation of phase change materials for target temperature, and derivation of thermo-physical properties. Market demand for latent heat storage is increasing to reduce the use of fossil fuel as a way to improve the efficiency of energy-intensive combustion systems through heat recovery. Accordingly, each government is proposing specific policies for thermal energy storage. Demonstration research is being carried out in Germany and Korea. The temperature range of the heat source generated in the high-temperature combustion system is mainly 100-300℃. For this purpose, applicable phase change materials were evaluated. It can be seen that the use of organic materials such as paraffin and fatty acid and inorganic materials such as salt hydrates is appropriate in the low-mid temperature range between 0-100℃ and that molten salt and mixtures thereof are suitable for latent heat storage in the high temperature range of 100-300℃. |
