Review of the State of the Art and Development Trend of Thermochemical Heat Storage Technology for Medium Temperature Applications
摘要
Energy storage is an effective solution to bridge renewable energy and industrial energy demand by alleviating their intermittency problems. Thermochemical energy storage (TCES) is a more efficient energy storage method in this application compared with sensible heat storage (STES) and latent heat storage (LTES), as energy is stored in strong chemical bonds via a reversible chemical reaction so that it can offer higher energy density with less energy loss during long-term storage and long-distance transport, due to the temperature-independent storage of the working pairs. In this report, the state-of-the-art thermochemical energy technologies are reviewed and discussed, especially for medium temperature applications (200–500℃), including material selection.
