Resumen
The project's goal is to develop and demonstrate novel modular, compact, high performances and
Plug&Play thermal energy storage (TES) solutions for heating, cooling and hot tap water production.
The new concept of TES proposed in the project will provide electricity load shifting with
meaningful peak shaving of the thermal and electric load demands. Furthermore, the exploitation of
renewable sources will be a key point of the new TES device considering at the same time the
cost-effective results in terms of energy, costs and sustainability of the system. The project will
provide a TES system able to store energy for heating and cooling in building applications for a
period of at least four weeks. The novel TES system will be based on a closed-loop TCM reactor
insulated by PCM and equipped with an ice storage, again integrated with PCM, for high cooling
energy demand. The thermodynamic cycle has been designed to benefit from a further PCM thermal
buffer tank, breaking through the closed-loop concept by compensating the energy for humidification
with its latent heat. An advanced heat pump will be finally dedicated to the power conversion
during the thermal charging process of reactor and PCMs storages, increasing the overall
performance. A dedicated control system will be developed to operate the TES according to the
energy production and the end-users' requirements, adapting to the conditions of use according to
the type of air conditioning system and the particular demand for domestic hot water. The TES
solution will be adaptable to all the different possible European scenarios, in terms of energy
policy and end-users' requirements. Tt will be designed to be used both as integrated into the
building heating system and in
eating and cooling network. Different characteristics of the system
ill be taken into account, ranging from storage efficiency and durability to cost reduction and LCA
and LCCA.
