On July 22, 2025, Technovative Solutions Ltd. (TVS) joined the Regional Stakeholder Workshop: Unlocking High-Temperature Geothermal Energy in the Canary Islands, collaboratively hosted by the COMPASS project, the EU-funded GreetGeo project, and the local partners at Gran Canaria in Spain. The participants, from a wide range of sectors, including developers, operators, researchers, and public authorities, explored the deployment of high-enthalpy geothermal systems in the Canary Islands. They discussed corrosion mitigation, EHLA technologies, flexible well completions, and local integration into the energy mix.
The workshop was held as a part of the COMPASS project stakeholder engagement efforts, led by two of the project’s consortium partners, COSVIG and GEORG, among the European island nations. Through the efforts, the project focuses on cost-effective, sustainable solutions for drilling and completing high-enthalpy geothermal wells. This dialogue helped the stakeholders come ahead to exchange knowledge and address local challenges of the Canary Islands, since the region is now set for deep drilling operations.
To represent TVS, Dr Hye Chowdhury, the Lead Technologist at the organisation, contributed to the workshop. We talked to him to gather his experience on his participation at the event to shape this blog.
Dr Chowdhury delivered a speech titled "Environmental and Financial Assessments of Superhot Geothermal Resources" in the first session "Presentation of recent technological results from COMPASS" of the workshop, . The presentation focused on demonstrations of cost and environmental impact estimators that are used for surface plants utilising superhot geo-resources. The discussion investigated whether COMPASS-enabled geothermal systems are environmentally sustainable or not for extracting energy from deep geothermal systems under superhot geofluid conditions. He also talked about whether COMPASS-enabled geothermal systems are financially viable and worth investing in or not.
After the presentation, the audience particularly showed interest in navigating the estimators TVS developed and requested access to that platform. They also queried about the Life Cycle Assessment (LCA) and Cost Modelling tools for geothermal systems as well.
The COMPASS workshop provided a rich platform, consisting of leading stakeholders in the field of geothermal energy from the Canary Islands, Iceland and Italy, where the organisations could exchange their interventions and opinions on leveraging geothermal energy to build a sustainable future. Through the event, TVS showcased its commitment to driving environmentally and financially sound geothermal innovation through the COMPASS project to the industry leaders.
TVS is currently leading two tasks in work package 7 (Social, Environmental and Economic Life-Cycle Assessment) of the COMPASS project. The first one is financial performance evaluation using the Cost Estimator for surface plants developed in work package 5 (Integrated Well Simulation and Decision Support System). The second task is an environmental performance evaluation using the Environmental Impact Estimator (EIS) for surface plants developed in the same work package.
About the Project
The COMPASS project is inspired by global efforts to improve utilization of geothermal resources by enlarging production fields downwards. Energy output can be enhanced, without the need to expand surface infrastructure, by drilling into deep and hot formations. Calculations indicate that wells drilled into superhot conditions will yield 5-10 times more than a conventional well which can significantly reduce the number of wells required.
COMPASS has received funding from the European Union’s Horizon Europe research and innovation programme under grant agreement no. 101084623.
