Thermochemical adsorbent APO-Tric extrudates for heat storage
Large-scale utilization of solar energy for heating and cooling applications depends on effective thermal energy storage that reduces the mismatch between energy supply and energy demand. Most known technologies for heat storage are associated with high thermal losses over long periods of time, exhibit accelerated degradation, or are not cost-effective.Our technology aims to overcome this challenge.
Thermochemical heat storage is a sustainable technology based on a reversible adsorption and desorption of gases on porous solids. Microporous aluminophosphates are excellent candidates as water adsorbents in heat storage applications.
Our team has developed a method for preparing extrudates from the adsorbent developed years ago at our department. The adsorbent is the second-best water adsorbent among aluminophosphates for the sorption heat storage of solar energy.
Developed by: Department of Inorganic Chemistry and Technology.
Technology readiness level: TRL3.
