Description

Underground Thermal Energy Storage (UTES) is a particularly good way of providing thermal comfort in northern countries (e.g. Norway and Sweden) as well as in central and eastern Europe (e.g.
Poland and Ukraine). The project involves development of innovative structures of Borehole Heat Exchangers (BHEs). Structures tested as a part of the project will aim to maximize the energy
effect (which is defined as a unitary power obtained in BHE, in Watt per meter).
Innovative constructions include the pipe system in the borehole. New composite coaxial pipes system will be developed. Coaxial constructions will be analyzed and compared to the traditional, Utube based ones. The coaxial construction give possibilities use it in a boreholes with greater depth than U-pipe design.
Research methodology is based on mathematical modelling of a individual BHEs as well as fields consisting of multiple BHEs, taking into account their interference. Modelling will be verified by in
situ tests on created BHEs. It is expected to conduct Thermal Response Tests (TRT) on every borehole. Next innowation is TRT results interpretation. TRT results will be interpreted using three methods. Additionally, thermal conductivity test will be conducted on minimum three Borehole Heat Exchangers. It is new test of BHEs.
Very important innovation for BHEs fields making in the future is optimization of drilling technology parameters. New methodology will be developed for in situ application - on the begginning of
BHEs drilling with large number of boreholes.
Promotion of research results via conferences, scientific journals, monograph and the Internet is expected.
PhD thesises will be prepared, also many MSc thesises. Mentoring will be executed.
