Problems and initial situation:

Thermochemical energy storage, based on reversible chemical reactions is an auspicious storage method, because: Particle related storage densities are very high Losses during storage period are neglect able new value-added chains can be created concerning new energy distribution systems based on waste heat recovery or increased use of regenerative (solar) sources

Available literature evaluates thermochemical materials and concepts optimistic concerning e. g. storage density as well as reaction behaviour.

Objectives and methods:

So the target of the precursor-project “SolidHeat Basic” and the current proposal “SolidHeat Kinetics” is to identify (SolidHeat Basic) and describe comprehensively all found materials (SolidHeat Kinetics) based on the database initialised in “SolidHeat Basic”.

The following methods of analysis are applied:

  • TGA / DSC
  • Powder X-ray diffraction
  • X-ray fluorescence analysis
  • infrared spectroscopy
  • software based identification methods for reaction kinetics
  • further methods for the identification of material properties (specific heat capacity, heat conductivity, thermal expansion coefficient...)

These physical and chemical methods are completed by the (further) development of a flexible and extendible materials data base, where all necessary information about certain thermochemical materials is available.
