Technology of Latent Heat Storage for High Temperature Application: A Review

To save energy and reduce CO2 emissions, the utilization of solar energy and waste heat using latent heat storage (LHS) has emerged as an attractive solution because of advantages such as large density of heat storage, constant-temperature heat supply, and repeatable utilization without degradation. This review describes research trends in LHS technologies using phase-change materials (PCMs) based on papers published from 2001-2009, and state-of-the-art LHS technologies for high-temperature applications over 100 degrees C, such as solid solid PCM, encapsulation of PCMs, PCM composites, solar power generation with LHS, and waste heat recovery systems.
