Complete list of activities for the dissemination of the GEOCOND PROJECT

[05/07/2018] - Overall approach and methodology

GEOCOND will follow a multidisciplinary and engineering oriented multilevel approach which at the same time will streamline and guide technical development in the different project areas and seeking optimization at system level. The focus of the project is system and user-oriented. The technical areas of GEOCOND follow a synergistic approach so that improvements in one area can benefit other areas of the project, seeking a balance between two a priori conflicting objectives: cost reduction and efficiency improvement. At the same time, the development of labscale tests and on-site demos will demonstrate the feasibility of technologies in a technical dimension, but also to allow a fair and realistic cost analysis of its implementation. Following this approach, the project has been divided into seven technical and one management are, with the following highlights:

 

WP1 – Geothermal Engineering - This area will ensure modelling and simulation at different levels, in order to incorporate solutions into different scenarios in terms of climate, building typology and soil conditions, amongst many other parameters. Simulations will be realized also to improve geometric characteristics of the SGE solutions by means of CFD modelling, using 3D simulation software. The specifications in terms of pipes diameter and configurations, grouting, sizes and dimensions set by WP1 are to be followed by the rest of partners within the development of their particular solutions and within the range of techno-economically accessible material parameters previously agreed on. Solutions with highest impact in terms of project KPI’s will be favoured. The area of engineering will also be responsible for the experimental design of the demo-level TRT tests, analysis of results and further optimization.

 

 WP2 - Geothermal pipes with improved ageing resistance and customized thermal properties – Several approaches will be proposed to improve the efficiency of shallow geothermal system such as: i) improve thermal conductive pipes by including carbonous particles in the plastic material, ii) reduce the thermal conductivities of the pipes by develop a pipe with a foamed internal layer.

 

 

WP3 – New additive for grouting applications: i) Functionalized silica: Commercial silane coupling agents will be used to develop a low cost chemical route to create chemical bonds between silica and carbon particles which are graphite, expanded graphite and graphite like particles having different thermal conductivity. Using these additives could be improve thermal conductivity of the grouting without increasing the amount of conductive additives and in consequence, reducing grout viscosity. ii) Heat storage materials for district installations. New low temperature transition Shape Stable PCMs will be developed from paraffin leading to an increase in the heat storage significantly in order to enhance the performance of the groutings employed in geothermal facilities at district level.

 

 WP4 – New grouting formulations and TSE - The progress that will be achieved after the realization of the GEOCOND project is focused on the production of a tested in relevant environment and ready to use admixture for grouting the borehole fields associated to the shallow geothermal installations with optimal performance permitting the reduction of the total borehole length (≈significant reduction of the installation costs associated to the boreholes). 

 

 WP5 – Validation of materials and technologies developed in relevant environment. – The development and validation area has two key roles within GEOCOND: first to ensure that the developed materials and solutions work as expected within the geological and thermal demands in a realistic setting; secondly to evaluate the techno-economic performance with respect to the standard state-of-the art best available solutions. The WP is subdivided into to fabrication tasks, in which an upscale of the lab scale solutions into a feasible, ready-to-install and safe material for testing is aimed. This include all measures and provisions to adapt or reprogram the fabrication tools that are most adequate for the task, as well as the needed fabrication protocols and specifications. Two in-situ test series, in Spain and Germany, will be performed based on the Thermal Response Test procedure and aimed at establishing not only the functionality of the new materials within the geological context, but also their relative performance.

 

 WP6 –Environmental, standardization and social impact monitoring. To complete the work done, an environmental, economic and social assessment will be carried out. All development in new materials needs to be checked against the needs for groundwater and soil protection, and if necessary adapted during the development process. Hence, the benefits derived from their incorporation will be quantified and discussed.

 

Finally, in WP8 the full management and risk assessment of the project will be provided, so that all the proposed developments are in line with the main objectives defined for the GEOCOND project. Dissemination and exploitation activities will target “take-up” actions within different companies (particularly SMEs) and sectors involved in the GEOCOND project to promote the growth of the implemented industrial materials and processes in WP7.
