Thermal Energy Storage Systems for Energy Efficient Buildings
An integrated solution for residential building energy storage by solar and geothermal resources.
TESSe2b project will enable the optimal use of renewable energy and provide advantageous solutions for 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) exploiting both solar and geothermal energy.

TESSe2b project is highly innovative as integrates innovative solution Phase Change Materials (PCMs) in thermal storage tanks, advanced energy management through smart self-learning model-based control system and enhanced Phase Change Materials in the borehole heat exchangers with the introduction of nano-enhancement materials in the PCM.

Demonstration and on-site monitoring evaluation of small scale TESSe2b solution at a single building in three pilot sites along Europe (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 targets to a 9 years return of investment for all the individual modules-components.

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