Applying chemical heat storage to saving exhaust gas energy in

It was proposed that the wasted heat be stored during the dehydration of Mg(OH) 2 with the reaction products of MgO and H 2 O, and that the stored energy be released in the hydration of MgO. The storage density of Mg(OH) 2 is 81 kJ/mol. However, the thermal conductivity of the pure Mg(OH) 2 is very low (within 0.15–0.16 W/m.K [11]).To increase the

Introduction to thermal energy storage systems

Thermal energy storage (TES) systems can store heat or cold to be used later, at different temperature, place, or power. The main use of TES is to overcome the mismatch between energy generation and energy use (Mehling and Cabeza, 2008, Dincer and Rosen, 2002, Cabeza, 2012, Alva et al., 2018).The mismatch can be in time, temperature, power, or
