CREATE – Compact REtrofit Advanced Thermal Energy Storage
DEVELOPMENT OF THE CREATE SYSTEM
The developed CREATE system features a modular prismatic storage module design, optimised towards compactness allowing the use of available volume in a building up to 21% more effectively than up to now used cylindrical closed storage systems. The storage material used is granulated potassium carbonate (K2CO3) and in the scope of the project a full system with three modules and a total of 1,250 liters of K2CO3 was build and experimental evaluated.

PROJECT PROGRESS
So far, the main project’s achievements revolved around (i) improvement of the salt performance such as power, stability and energy density; (ii) development and optimization of a prismatic shaped absorber vessel to improve stackability and space requirements; (iii) development and optimization of low-cost evaporator/ condenser; and (iv) optimization of the full-scale system on basis of lab experiments and annual simulation.
DEMONSTRATION
Implementation of the CREATE concept is taking place in a typical European dwelling. To demonstrate the applicability of the thermochemical storage solution and its operation in real-life conditions as well as to receive an early user feedback, the CREATE system will be installed in a full-scale into an orphanage in Warsaw, Poland. The climate at the location is characterized by cold winters and warm summers. The demonstration started in summer 2019.
