Geothermal monitoring for installation and operation with integrated consumption monitoring for individual optimization of the heat pump

Project Objectives

The objectives of the project are to develop a quality assurance and monitoring system for borehole heat exchangers (BHEs) based on dielectric high-frequency spectroscopy and a monitoring system which coordinates the habits and individual needs of the consumer with the heating system (conventional heat supply in combination with a ground-coupled heat pump).
The integration of the measuring system, the real-time monitoring of process parameters as well as the high spatial resolution of the obtained data enables error analysis in case of incomplete backfilling and long-term environmental monitoring of BHEs.

EIFER’s Contribution
  • Techno-economic market analysis for BHEs for a proper monitoring system setup
  • Basic dielectric characterization of relevant backfilling materials
  • Design and installation of pilot test rigs for evaluation of the monitoring system functionality
  • Simulation of different test conditions (backfill material, BHE system arrangement, cavities etc.)
  • Evaluation of test results and optimisation of test procedures and the monitoring system prototype
  • Acquisition of potential industrial partners for commercialization of the monitoring system
