Thermochemical Sorption Systems can provide multiple functions, including storage of low-grade thermal energy, heat upgrade, cold production and provision of power when coupled with adequate turbomachines. As such, they have the potential to play a significant role in the decarbonization of industrial processes whose energy demand is dominated by thermal needs. Thermochemical Resorption Systems exploit two reversible solid-gas chemisorption reactions to store thermal energy in the form of chemical potential during the charge phase, while producing cold and/or heat during the discharge phase. This work investigates the performance of a thermochemical resorption system for recovery and storage of low-grade heat and cogeneration of cold and power (TRSC), by means of a scroll expander.
