75% of EU Building Stock is energy inefficient meaning that buildings hold untapped potential for renewables and energy efficiency. Such improvement would undoubtedly add to decarbonising the EU economy and ensuring security of supply and cost savings to many households across the EU. Shallow Geothermal Energy Systems (SGES) is stable, reliable and renewable source of energy.
Some of its key features, in comparison with RES include:
• Available and applicable everywhere
• capable of providing both heating and cooling
• high efficiency in cooling
Borehole Heat Exchangers applying SGES technology are currently installed in over 1,4 million sites across the EU with combined capacity of over 16,500 MWth
Why do we need to develop this technology further?
• unlock the great potential of geothermal energy sources
• gain competitiveness and increase awareness
• penetrating further the market of building construction and renovation
*District Heating and Cooling needs improved heating and cooling storage technologies which could largely benefit from enhanced Underground Thermal Energy Storage (UTES) technologies.
The specific technological objectives of the project can be summarized as follows:
Geothermal pipes improved (at least 15%) thermomechanical ageing resistance and surface properties (external layer good adhesion to grout and internal low flow resistance).
High thermal Conductive HDPE pipes and fitting elements.
New pipes configuration based on the use of pipes with different thermal conductivities and diameters.
New additive for grouting: Low cost structures based on chemical bondings of silica (quartz) and thermal conductive carbonous particles.
New additive for grouting: Shape Stable Phase Change Materials (SS PCMs) with low tran-sition temperatures (30-35ºC) for heat storage at DHC
Tailor-made performance grouting and thermal soil enhancement technologies (TSE).
Material Selection Support System within an engineering methodology to optimize efficiency and minimize costs.
