Competitive Advantages
- Accommodates expansion of PCMs at elevated temperatures
- Withstands more thermal cycles than current TES systems
- Greater amount of energy storage
- Can be used for new or existing TES systems
Summary
Our researchers have developed a novel method of manufacturing PCMs that involves coating the PCM in a flexible material to allow for the expansion and shrinkage of the pellet during phase changes and then coating the pellet in metal to extend its lifespan. Initial testing with a potassium nitrate-sodium nitrate coating showed that the pellets lasted for over 2,000 thermal cycles at 202-242°C with little degradation. These properties make the novel PCMs ideal for industrial applications in solar plants and other power plants. Additionally, they are easily implemented as they can be retrofitted to existing TES systems or designed for new TES systems.
