Sealing Borehole Heat Exchangers (BHE) – Enhancing Hydraulic Integrity for Sustainable Geothermal Heating
About
We are preparing a proposal for the upcoming CETPartnership Joint Call 2025 – Call Module 6: Heating and Cooling Technologies (TRI4).
Our focus is a laboratory-based determination of the vertical hydraulic permeability of grouted BHE assemblies under realistic pressure and temperature conditions, using different pipes and backfilling materials. We aim to investigate:
-
Material and system sealing capacity under varying curing and operational conditions
-
Processes potentially occurring during backfilling (e.g., annular gap formation due to pressure tests)
-
Influences of emulated operational thermal and mechanical stresses
-
Correlations between installation parameters and sealing quality
-
and support regulatory reviews governing the construction and operation of BHE
We are looking for international partners from CETP-participating countries, especially:
-
Research institutes or universities with expertise in BHE, geotechnics, materials science, hydrogeology, or environmental protection
-
BHE drilling & installation companies (practical expertise, installation procedures, construction requirements)
-
Manufacturers of BHE pipes and backfilling materials (pipes, and grouts)
-
SMEs developing sensor technology, quality control tools, or installation equipment for geothermal boreholes
-
Public authorities or agencies with interest in standardisation and regulatory uptake
