Phase change materials (PCMs) having a large latent heat during solid-liquid phase transition are promising for thermal energy stor-age applications. However, the relatively low thermal conductivity of the majority of promising PCMs (<10 W/(m K)) limits the power density and overall storage efficiency.
In phase change thermal energy storage technology, PCMs play a crucial role in determining the performance of the energy storage system. Researching and finding safe, reliable, high energy density, and high-performance PCMs is key to the advancement of phase change thermal energy storage technology. 2.2. Principles for selecting PCMs
Among these, solid-liquid phase change offers larger latent heat compared to solid-solid phase change and exhibits smaller volumetric expansion compared to gas-liquid phase change. As a result, solid-liquid phase change thermal energy storage technology has been widely applied in practical engineering.
In particular, the melting point, thermal energy storage density and thermal conductivity of the organic, inorganic and eutectic phase change materials are the major selection criteria for various thermal energy storage applications with a wider operating temperature range.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
