Requirements to consider when choosing a thermochemical material for solar energy storage

摘要: Abstract Solar thermochemical reactors offer good potential for production of heat residential space heating and cooling domestic hot water. The materials able to store solar energy are called which based on reversible chemical reactions, focusing here solid–gas ones. These capable thermal in one direction release it the other, whenever is needed, with almost no losses. In literature several have been successfully analyzed tested at lab scale, but expected storage capacity, or yield, reactor implementing these not achieved. This paper shows that order reach calculated operation conditions, a detailed proper characterization solid involved needed (including solubility reactants products, evaluation crystallographic structure changes). Furthermore, reliable kinetic model should be obtained predict further behavior design suitable reactor. main goal this provide correct pathway obtain regarding important features considered when working storage.
