STO1 is at an advanced stage, since WP1 is completed. The IDDS methodology has been adapted to geothermal retrofitting, explained in dedicate workshops and is currently being applied to all pilots. ICT tools for ground research (GPR ) and worksite monitoring (UAV, accelerometers, GBInSAR) are being prepared for application to selected pilots. Information Delivery Manual (IDM) has been conceived specifically for Drilling Processes. BIM activities (WP6) are ongoing (BEP plan and cloud-based platform specifications have been provided ; BIM library for the components designed in WP4 have been set-up and first GEOBIM models for some pilot sites have been created.
STO2 is being tackled in WP2, WP3 and WP4. Task 2.3 already investigated main damaging mechanisms acting in drilling tools, establishing the base to properly recommend solutions in materials selection. Methods to calculate the thermal response of ground heat exchangers have been investigated and the overall design process for novel ground (slinky/earth basket) type shallow heat exchangers has been described, providing information and procedures for data collection and evaluation.
WP4 studied heating and cooling needs of 2 pilots based on modelling software, suggesting LTH and HTC systems and simulating their performance, evaluating it against comparable alternatives. The main heat pumps configurations (both electrically and thermally driven) and their design and control through numerical models have been investigated and optimal solutions have been identified.
STO3 is mainly addressed in WP5. At present, monitoring devices have been installed at pilots. To do so, different degrees of integration in the existing BEM have been applied. Based on the final configuration of devices to be installed in pilots (Heat Pumps and their control systems; LTH/HTC technologies and their control systems), a high level control strategies, robust and cloud-based, will be developed and applied, enabling for testing of flexibility services capabilities.
STO4 is to be reached by demonstrating GEOFIT’s innovative results to pilots. At present, the IDDS process is being applied to pre-design and design phases (Design and pre-intervention monitoring). Successive phases of IDDS, such as installation, commissioning and operation, will be faced as soon as pilots construction starts.
STO5 is transversal to the entire project. At present, IDDS methodology is being showcased and dissemination and exploitation activities will from now on establish it in the daily business of construction and engineering companies working on geothermal based retrofitting.
Guidelines have already been issued in WP1 and WP3. Implementation Procedures and Installers Manual has been drafted and will be delivered in Month 20.
Communication activities (WP10) have started early in the project and have delivered high-quality material in a regular way (logo, website, poster, brochure, video, interviews). News on the GEOFIT website are being published regularly, at least once a month.
Basis for full deployment and exploitation of EGS has been created with Market Watch activities and Market Analysis and with the Exploitable Results Table.
