Assessment on Circular-by-design concepts

Potential circular-by-design solutions for geothermal wells will be investigated and analyzed, including advantages of using novel technology compared to SOA well completions, potential re-use of wells, e.g., converting to injection wells and/or for carbon mineralization storage, re-casing wells to prolong their production period, thermal storage, etc. Additionally, improved circularity potential of above surface processes will be investigated, e.g., thermal efficient co-generation using waste heat to produce hot water and other processes down the value chain, e.g., fish farming and greenhouse farming. Work will build on inputs from WP3, WP4, WP5 and WP7. In addition to KPIs defined in Task 2.4 for material selections, requirements for installation, operation, maintenance and end-of-life will be also considered. The developed software in WP5 will be extensively used to analyse several scenarios related to well construction alternatives, making use of the developed technologies in combination with other available solutions.

Report on social engagement

This task is aimed to engage with local communities to improve their awareness and acceptance towards geothermal. Results from T7.3 will be further analysed to map existing experiences of societal engagement and actions to promote the social acceptance towards geothermal energy and other energy facilities. Citizens will have the opportunity to contribute to the decision-making process of COMPASS solutions through engagement campaigns to ensure that most interesting and constructive feedbacks contribute to the project’s decision-making. A press campaign coordinated by COSVIG will be launched around month 14 up to the project end, with publication of informative articles on COMPASS findings and geothermal in local newspapers (both online and printed versions) and energy sector magazines. In a second step, communities living close to geothermal sites will be engaged in workshop(s) around month 28. These events will present project results and potential risks and benefits for local communities related to deep geothermal facilities. A participatory session (e.g., world café) will complement the events, to better understand communities’ expectations, co-design resource usage and how to follow up to continue with the societal engagement after these events, prepare findings briefs, videos to communicate (WP8) the participatory process narrative.

Data management plan

Describes how data required for the project will be managed and curated COMPASS will provide open access OA to research outputs eg publications data models material and components design etc through deposition in trusted repositories and digital tools for well simulator and decisionsupport accessible for geothermal communities through a webbases solution In fact partners will provide OA to peerreviewed scientific publications relating to their results The authors of all peerreviewed scientific publications will choose the most appropriate way of publishing their results and these publications will be stored in an OA trusted repository during and after the projects life The consortium will be encouraged to publish in the httpsopenresearcheuropeeceuropaeu platform

Cost performance of COMPASS geothermal plant

DSS developed in WP5 and with the support from all the partner, two case studies will performed, one case study will be around IDDP-3 in Icelandic supercritical/superhot resource scenario and the other will be around Tuscany in Italian resource scenario. Two case studies will elaborate the specific cost of plant, operation and maintenance cost of the plant, LCOE, and other financial indicators (for investment decision support) such as NPV, IRR, ROI etc. with sensitivity analysis.

Cement properties testing solution

For a fast design of reliable foam solutions, the current test rig developed by CURISTEC in previous geothermal projects will be further adapted up to ~450°C, allowing a continuous testing of the developed cement systems, both the short-term properties (hydration) and long-terms properties (set-cement), simulating the changes of cement properties as function of time in field conditions.

Communications guide for geothermal projects

The task will perform a meta-review of existing information and research literature. Drawing on EU funded project reports (see non-exhaustive list in 1.2.2) and partner’s own internal information sources). The COMPASS consortium includes SSH expertise covering several fields of science required to extract and collate relevant information available from several sources (e.g., economics, acceptance and NIMBY issues, policy and governance linked to licensing etc.). The NIMBY and social acceptance were reported by several H2020 projects (e.g., GEOENVI, GEORISK) and H2020-Crowdthermal has recently produced information and tool for social license to operate geothermal projects. The life cycle costing and LCA has been in focus of numerous projects and Environmental, Social and Governance (ESG) risk exposure for geothermal projects will be reviewed as well to establish baseline information for wider take-up of COMPASS results for wider deployment of geothermal energy as realistic renewable energy choice in more European regions.

LCA of COMPASS enabled geothermal plant

Using the LCA models developed in WP5 and with the support from all the partner, LCA studies for IDDP-3 will be conducted to represent Icelandic supercritical/superhot resource scenario and the Italic superhot resource scenario. Two case studies will elaborate the environmental impact for per MWh of energy production, different impact assessment methodology will be used such as IMPACT 2002+ (version 2.15) which will provide the life cycle impact assessment (LCIA) results in 15 midpoint impact categories, and 4 endpoint damage categories which includes Human health (in DALY), Ecosystem quality (in PDF*m2*yr), Climate change (in kg CO2 eq), Resources (in MJ primary).

Optimal retarders for developed foam cement

Novel cement retarders based on hybrid silica nanomaterials, previously developed by SINTEF, will be further designed for foam cements, ensuring sufficient thickening time for cement displacement in high-temperature wells, ensuring a reliable cement job for geothermal well drilling and completion. Different recipes will be synthesized and mixed with developed foam cements. Effects of the developed retarders on slurry properties (density, thickening time, rheology, early strength development) under relevant temperature and pressure will be investigated in the lab and benchmarked. The test results will be used to provide inputs for cement placement model in Task 5.1 and to select optimal solutions for further testing in Task 3.1.4.

Characterization of geothermal fluid & environment

We will map out physical and chemical conditions to be expected in future superhot wells, including estimations on the temperature, pressure, fluid composition and fluid phase. This will be based on information on properties of surrounding wells and information gathered from the previous IDDP, and other extreme wells that give information on greater depths (~4.5km). We will further characterize the chemical properties of the deep, superheated steam in the Hengill geothermal system by collecting deep downhole samples at selected depths in 3-4 wells in the hottest part of Nesjavellir field. The results of this downhole sampling will test the validity of using chemical analysis of IDDP-1 steam as a proxy for deep fluids in Hengill. This data will be used in WP3 for flexible foam cement design and WP4 for pre-screening and design of testing regimes for cost-effective casing corrosion control solutions.

Final DSS integrating well design, cost and LCA

To determine whether an energy technology can reach commercialization, a set of acceptance criteria when undertaking well design of a (deep) geothermal well with also be established in addition to cost and LCA model developed in T5.5, based on the specifications defined in T2.4. A user-friendly graphical user interface (GUI) along with visualization module will be implemented, efficiently visualizing the analyzed data, risks, and acceptance criteria for different investigated scenarios. This will provide a comprehensive overview and detailed insights, supporting a more precise and efficient decision-making process. A DSS web app with an interactive rich human graphical user interface will be built on top of several APIs which are developed in this work package.

The potential spill over effect of the project

The effect our project can have for other geothermal applications will be addressed, including the effect on conventional geothermal production. Through literature review and research, we will address how our technology and methods can improve geothermal well design as there are numerous issues regarding well integrity. Moreover, we will also look at the potential broader use of these methods, for instance in adapted oil and gas wells, to investigate the full range of environments, where our technology and methods can be useful.

Project Management Plan (PMP)

A Project Management Plan to be issued in M2 and updated in M18

KPI definition for cladding and cementing validation

To ensure a successful well design, KPIs related to cladding and cementing performance will be formalised with the assistance of the advisory board. This will be a live document, updated as the project progresses and new KPIs added if required. These KPIs will be used to validate the cladding and cement solutions in a credible scientific manner for work in WP3 and WP4 along with validation activities in WP6.

Replication potential of COMPASS solutions

The aim of this task is to evaluate the replicability potential of the technologies developed within the COMPASS project across the geothermal sector. Main results obtained from the technologies developed in previous WPs will provide the key guidelines to define the replication strategy and duly consider implications that may arise from exploitation and IPR management needs (T8.2). Replicability in geothermal utilization is complicated due to the heterogeneity inherent to this energy source at a wide range of geological settings. Therefore, the results will be tailored to fit further deployment and development needs post-project, suitable for geothermal energy development in new regions. The replicability of developed novel technologies suitable for superhot/supercritical geothermal is also well suitable for economical adaptation in less harsh geological conditions. These analyses will provide the replication plans for each technology developed in the project.

Optimal foam cements for high temperature wells

Selected cement systems (from Task 3.1.1 and Task 3.1.2) will be tested using the test rig developed in Task 3.1.3. The hydration properties (cement shrinkage, pore pressure) and set-cement mechanical properties (e.g., deformation, strength) in representative down-hole conditions will be monitored during the testing. The tests data will be used to calibrate well cement models developed in WP5 (Task 5.1 and Task 5.2), and to select the optimal cement systems for further verification in WP6.

Training and educational pilots

This task will build on to overall COMPASS results and combine with results from T7.2, 7.3 and T7.4 to prepare training modules and launch a series of regional workshops supported by WP8 (combined in person & webinars) focusing social research context results in combination with the core technical outcomes. Special target regions in addition to Iceland and Italy would be e.g., Canary Islands, Crete and Greek islands with potential to deploy renewable deep geothermal energy projects that would provide local energy to isolated islands currently dependent on imported energy like fossil fuels. The workshops will cover technical challenges requiring solutions for more sustainable geothermal energy developed by COMPASS in relation to high-level events in the geothermal sector. The project consortium is committed to attracting future students into a career in deep geothermal development and operations. This will e.g., be accomplished in part through a COMPASS Summer School for next-generation geothermal engineers and scientists that will be hosted during the last project year. The objective of the summer school is to teach the current best practice workflow for lowering costs and increasing the efficiency of geothermal operations. The final international conference or session will be run in the vicinity of one of the partner’s sites and attract different stakeholder groups.

Enhanced laser cladding hardware solution

Hornet will design, procure and deploy appropriate equipment and hardware for a high-performance EHLA cladding solution to enable manufacture and testing of specimens in WP4. The goal is to increase the productivity of the process through improved surface coverage speed (50%), which can be achieved through the development of a SOA higher power process head (~6kW).
