Summary

Chemical energy storage (CES) uses a chemical-sorption process to store energy. This experimental study investigates the performance of a CES system that uses sodium sulfide-water. To form a reactive mixture, sodium sulphide nanohydrated salt was mixed with a graphite binder. A prototype using this reactive mixture was comprised of an annular tube reactor, an evaporator and a condenser. The experiment investigated the effect of three variables, which are evaporating temperature (40-50 °C), regeneration temperature (110-120 °C), and cycle time (45-75 minutes).
