Project Overview

TESSe2b Project - Thermal Energy Storage Systems for Energy Efficient Buildings is a EC financed H2020 four years project, that develop an integrated solution for residential building energy storage using solar and geothermal energy, with the purpose of correcting the mismatch that often occurs between the supply and demand of energy in residential buildings.


TESSe2b design, develop, validate and demonstrate a modular and low cost thermal storage technology based on solar collectors and highly efficient geothermal heat pumps for heating, cooling and domestic hot water (DHW) production.


That is achieved by integrating compact Thermal Energy Storage Tanks with Phase Change Materials (PCM TES) coupled with enhanced Phase Change Materials inside the borehole heat exchangers (BHEs), and an advanced energy management smart self-learning control system.


Demonstration and on-site monitoring evaluation of small scale TESSe2b solution at a building in three pilot sites (Austria, Spain, Cyprus) conducted with the aim of evaluate the system’s integration into building space, assess the impact of TESSe2b solution in different climates and provide evidence about its overall technical and economic feasibility.


TESSe2b project has received funding from the European Union’s Horizon 2020 Research and Innovation Programme, under the Grant Agreement number 680555.
