Thermochemical energy storage (TCES) shows great potential in solving the stated problems for clean cooking. This report focuses on TCES using salt hydration for storage of solar energy for time-shifted cooking and reaction initiation by hydration using liquid water. Various salts are considered for the application and from evaluation of properties and fit with context, two kinds of salts have been found best fit for utilising in a clean cooking salt hydration application. Through two test iterations with prototype rigs various parameters of both hydration and dehydration have been tested. Results show that salt hydration do have potential as a means of energy storage technology to be used for clean cooking solutions if certain parameters can be optimised.
