The current need to carry out an energy transition towards a 100 % renewable horizon places the energy storage as the key. Thermal energy storage has the potential to be an optimal technology. Nowadays electrical resistors are used to convert electrical energy to termal energy by heating an air flux which is stored afterwards. In this work, it is proposed to use a multistage thermoelectric heat pump (MS-TEHP) to do this energy conversion. It has been experimentally analyzed and compared the performance of two MS-TEHP with different internal heat exchangers. With this preliminary research, it has been demonstrated the feasibility of this novel thermoelectric technology which aim is to improve the energy conversión process for thermal energy storage.
