SHALLOW GEOTHERMAL DAYS [download the programme of this workshop by clicking on the title]

December 11, 2020
Brussels, Belgium
EGEC, GEOCOND

Synopsis:

The third day of the Shallow Geothermal Days 2020 focused on key concepts and measures to widen the scope of shallow geothermal in Europe. This session looked at the novel and promising technological concepts and good practices to operate and manage shallow geothermal in an efficient and sustainable way. The session addressed solutions from Europe and abroad.

This 2020 event was organised by the European Geothermal Energy Council (EGEC), the Renewable Heating and Cooling Platform (RHC-ETIP), GEOTRAINET aisbl and Geothermal DHC COST action, with the support of the GeoERA-MUSE project, EuroGeoSurveys, GEOCOND project and EHPA.

WORKSHOP ON THE TECHNOLOGICAL ADVANCEMENTS IN CEMENT ADDITIVES FOR RENEWABLE AND SUSTAINABLE THERMAL ENERGY STORAGE [download the programme of this workshop by clicking on the title]

9:30-12:30, January 12, 2021
Istanbul, Turkey
Sabanci University Integrated Manufacturing Technologies Research and Application Center &Composite Technologies Center of Excellence, Istanbul, Turkey

Synopsis:

The GEOCOND (Advanced materials and processes to improve performance and cost-efficiency of Shallow Geothermal systems and Underground Thermal Storage) project, with a unique consortium of Companies and leading Research Institutions in the area of SGES and Materials, focuses on four key development areas in a synergetic and system-wide approach: development of new pipe materials, advanced grouting additives and concepts, advanced Phase Change Materials and system-wide simulation and optimization. This workshop covers the suitable selection of carbon-based materials (graphite, graphene and carbon-by-products from waste sources) and Phase Change Materials (PCM) and the development of silica-carbon based hybrids by tailoring surface composition to improve the thermal conductivity and provide homogeneous suspensions in grout mixes. The interfacial interactions between carbon-based additives and grout constituents are explained by providing understanding the importance of surface chemistry. In addition, this workshop explains the properties of organic PCM and how they work allowing storage of thermal energy in the form of latent heat. The participants are able to understand the motivation of using PCM in SGE applications, diversity of PCM, why it is important to impart shape stability to organic PCM, how it can be done and how it was done actually within GEOCOND project framework, the considerations of importance in engineering and manufacturing Shape Stable PCM. Furthermore, the assessment of market potential of GEOCOND’s developed additives, route to the market, market drivers and the importance of circular economy in cement industry are analysed from an industrial point of view.

WORKSHOP ON CEMENT BASED-GROUTING [download the programme of this workshop by clicking on the title]

9:30-12:30, January 22, 2021
Stockholm, Sweden
RISE, UBeG and UPV

Synopsis:

This course describes the cement-based grouting that is used as backfill of boreholes for heat exchange in shallow geothermal energy systems (SGES). The course starts with an overview of SGES and the corresponding objectives in the GEOCOND project. It will be then continued by outlining the role of grout and the required properties. Following that, the grout development process, the final recipes and the associated testing and properties will be presented. Afterwards, a laboratory-scale test, which was a small-scale replication of a geothermal heat exchange borehole in a sand box conducted using the developed grouts, will be demonstrated. Subsequently, different aspects and the significance of proper grout mixing in practice will be discussed. Eventually, two large-scale field tests conducted in two different facilities in Valencia (Spain) and Borås (Sweden) will be summarized. The course will be finally summed up by concluding remarks and answers to the questions raised by the participants.

GEOTHERMAL LABORATORY FOR EXPERIMENTAL THERMAL TESTS [download the programme of this workshop by clicking on the title]

10:00-13:00 (CET), February12, 2021
Polytechnic University of Valencia, Valencia, Spain

Synopsis:

This session showcases the geothermal laboratory at the Polytechnic University of Valencia, in Spain. The first presentation shows a virtual tour of this facility, detailing its main features and singularities, which make this laboratory a reference facility. The session also focuses on the main stages of a typical experimental thermal test. Following this educational aim, an immersive virtual reality laboratory, designed for this purpose, is used for the explanation of how this facility operates. The session includes a Q&A section as well as a round table.
