Home / Thermal Energy Systems / Development and testing of thermal energy storage systems

 

The development activities for innovative thermal energy storage systems range from characterization and optimization of materials and components up to the testing of lab-scale prototypes, both for residential and industrial applications.

Concerning the latent thermal storage technology, main activities focus on:

  • Identification and characterization of organic and inorganic materials, optimized for the given application
  • Cycling stability evaluation of the phase change materials (PCMs)
  • Heat exchanged desig optimized to achieve high energy and power density
  • Design, manufacturing and testing of lab-scale prototypes

The main instrumentations and software employed for these activities are the following:

  • DSC Mettler DSC-1
  • Transient plane source thermal conductivity analyzer (Mathis-TCi)
  • Testing rig for thermal storage prototypes, with 20 kW thermal capacity
  • Comsol Multiphysics 5.4

Concerning the thermochemical thermal storage technology, main activities focus on:

  • Development and characterization of sorbent composite materials for seasonal thermal energy storage technology
  • Evaluation of hydrothermal cycling stability of adsorbent materials
  • Design of reactors, evaporators and condensers for closed systems thermal energy storages
  • Experimental testing of advanced heat exchangers integrated with sorbent materials for thermal energy storage
  • Experimental testing of prototypes and systems for thermochemical thermal energy storage

The main instrumentations and software employed for these activities are the following:

  • Thermogravimetric apparatus for sorption equilibrium measurements on solid and liquid (DVS Vacuum)
  • TG/DSC for sorption measurement under saturated vapour conditions
  • Testing rig for hydrothermal ageing conditions
  • Testing rig for thermal storage prototypes, with rated capacity of 60 kW
  • Comsol Multiphysics 5.4
  • Dymola 2018
