Description du projet
Des systèmes géothermiques pour des bâtiments à haut rendement énergétique
Les systèmes d’énergie géothermique superficiels (SGES) constituent une source d’énergie stable, fiable et renouvelable pour les bâtiments. Ils présentent l’avantage d’être omniprésents et d’assurer une efficacité inégalée en matière de chauffage et de refroidissement. Ils doivent toutefois encore surmonter divers obstacles, et notamment éliminer les barrières du marché et devenir compétitifs. Il convient également de développer la nouvelle génération de systèmes géothermiques avec de nouveaux matériaux et d’exploiter des technologies améliorées de stockage souterrain d’énergie thermique (UTES). Le projet GEOCOND, financé par l’UE, relèvera ces défis en développant des solutions qui permettront d’améliorer les performances thermiques de divers sous-systèmes d’un SGES et d’un UTES. La combinaison de solutions matérielles, d’une ingénierie sophistiquée, de diverses optimisations, d’essais et d’une validation sur site permettra d’atteindre objectif. Le projet s’est, entre autres,fixé pour objectif de réduire les coûts globaux de 25 % et d’accroître la compétitivité.
Objectif
The 75% of the EU building stock is energy inefficient. Buildings hold a large untapped potential for renewables and energy efficiency in order to decarbonise the EU economy, to ensure security of supply and to provide cost savings to EU households and businesses alike. In this context, Shallow Geothermal Energy Systems (SGES) are a stable, reliable and renewable energy source with some key features compared to many other RES: being available everywhere and being capable of providing not only heating, but also cooling with unparalleled efficiency. Amongst SGES, closed loop systems with vertical Borehole Heat Exchangers enjoy the widest deployment in the EU where the total installed number of GSHP units amounts nowadays to about 1,4 million, representing an installed capacity of about 16.500 MWth. Against this background, there is still a need to remove market barriers and gain competitiveness, but also to develop the next generation of geothermal systems with new materials for penetrating further the market of building construction and renovation. Also the area of District Heating and Cooling needs improved heating and cooling storage technologies which could largely benefit from enhanced Underground Thermal Energy Storage (UTES) technologies. By a smart combination of different material solutions under the umbrella of sophisticated engineering, optimization, testing and on-site validation, GEOCOND will develop solutions to increase the thermal performance of the different subsystems configuring an SGES and UTES. An overall cost reduction of about 25% is the overall aim, leading to a substantial gain in competitiveness. GEOCOND, with a unique consortium of Companies and leading Reseach Institutions in the area of SGES and Materials, will focus on four key development areas in a synergeic and system-wide approach: development of new pipe materials, advanced grouting additives and concepts, advanced Phase Change Materials and system-wide simulation and optimization.
