This work presents a development and investigation of a 'trimodal' energy storage material that synergistically accesses a combination of phase change, chemical reaction and sensible.
By simply warming a material, we can store substantial amounts of energy, which is released later as it cools. This storage can be achieved by heating the material, by driving a phase transition or by inducing a chemical reaction (such as dehydration, which releases water molecules).

How can thermal energy storage materials be highly thermal-energy dense?
The creation of materials that are highly thermal-energy dense can now be achieved by combining two components that work together to simultaneously undergo a solid-to-liquid phase transition and a dehydration reaction. This is a summary of: Saher, S. et al. Trimodal thermal energy storage material for renewable energy applications.
During discharge, the thermal energy storage material transfers thermal energy to drive the heat pump in reverse mode to generate power, as well as lower-grade heat that can be used in various other applications.
What are the different modes of thermal energy storage?
Various modes of thermal energy storage are known. Sensible heat storage represents the thermal energy uptake owing to the heat capacity of the materials over the operational temperature range. In latent-heat mode, the energy is stored in a reversible phase transition of a phase change material (PCM).
