Research project

COMTES – Combined development of compact seasonal thermal energy storage technologies

COMTES main purpose is the development and demonstration of various techniques enabling to store heat over a long period (seasonal storage) with a high energy density and with less losses than conventional water storage. This should enable to increase the building heat solar fraction coverage.At SPF, investigation are lead on an absorption/desorption concept using sodium hydroxide (NaOH) and water as thermochemical heat storage mediums.

 

EMPA and Kingspan Renewables are SPF main project partner in this subproject line. The project is supported European Union's in the frame of the FP7 Research and Innovation funding programme (FP7, Project no. 295568)

Duration: 01.04.2012 - 31.03.2016
