The main achievements in the reporting period were as follows:
• Formalisation of end user specifications for the two demonstration sites in Balmatt (Belgium) and Zorlu (Turkey) (WP1);
• User workshops to generate the integration document with site specific data and proposed innovations at the demonstration sites (WP1 & WP10);
• Development of safety and risk register for demonstration sites to include information on equipment safety legislation codes, operational conditions and specification designs (WP1).
• Identification and selection of phase change materials in accordance with the site requirements (WP2);
• Design of thermal storage units for demonstration sites based on input data from the demonstration sites (WP2);
• Development of physical models for the different components of the ORC including the pump, heat exchangers, expander and piping (WP3);
• Work on preliminary design and control strategy for the aquifer-based hybrid cooling of the ORC (WP3);
• Work on production of the individual and overarching energy management and control systems and optimisation of the combined flexible ORC, thermal energy storage and aquifer-based hybrid cooling system for application at the Balmatt demonstration site (WP3 & WP6);
• Design of retention tank unit following the heat exchange unit to allow for silica scale formation prior to re-injection (WP4).
The main achievement in the RP2 were as follows:
• Following the change of demo sites, the key performance indicators (KPIs) were re-evaluated for relevance;
• New site specific (Insheim and KIZILDERE 2) integration documents including Process flow diagrams (PFD) and Piping and Instrumentation diagrams (P&IDs) were formalised to define the integration of the GeoSmart innovations on the demo sites;
• Previously established site specific safety and risk registers were updated to include information on relevant equipment safety legislation codes, operational conditions and specification designs.
Insheim site
• Design of pressurized water thermocline storage (10 MWh) as the TES of choice;
• Development of adiabatic cooling system specifications for air cooled condenser;
• Development in progress for implementation of a flexible energy management of ORC and district heating using a secondary cycle with industrial water.
Kizildere 2 site
• Finalization of design of two types of storage systems:
o Steam accumulator (5 MWh) and a Phase Change Material (PCM) module (2 MWh).
• Decision on final material choice (HITEC salt) for PCM module;
• Design and development of a small scale test module (PCM and HX) for laboratory testing in CEA and Fraunhofer respectivley;
• Design, development and delivery of a scaling reduction system for installation at Kizildere 2 site;
• Formalisation of detailed planning document for procurement of materials (tendering) to fabrication, installation and demonstration of the storage and retention tanks on Kizildere 2 site.
The main achievements in RP3
• Finalisation of design, installation and monitoring of the Adiabatic cooling system for energy efficiency Insheim
• Finalisation of design, manufacture and installation of the thermocline as thermal energy storage at Insheim site
• Development of model for flexible heat extraction and ORC operation at the Insheim site, show model functionality at Insheim site
• Establishment Database Module supports the effective management of maintenance tasks and activities for equipment within the GeoSmart system. It serves as a centralized repository for organizing and tracking equipment data, maintenance tasks, and failure modes, ensuring efficient management and recording of all maintenance operations at insheim site
• Integration and monitoring of the RT system
