Topic description
Expected Outcome: Deep sedimentary/basement reservoirs are usually characterized by low permeability, high drilling cost and a scarcity of data, as they are typically ignored by hydrocarbon exploration. Major exploration challenges relate to predicting deep sedimentary and basement reservoir structures and properties to identify suitable locations for reservoir-independent approaches, capable of overcoming the low permeability obstacle, such as Enhanced Geothermal Systems (EGS) or closed-loop geothermal systems. Project results are expected to contribute to all of the following expected outcomes: Increased knowledge base for developers to unlock unexploited geothermal resources, increase drilling success rate, increase geothermal sources performance and reduce the risk of induced seismicity and deploy geothermal energy in a sustainable way in environmental (notably on biodiversity and pollution) and socioeconomic terms. Citizens and local communities are engaged and benefit from local, more secure and affordable renewable energy sources. Scope: Advanced methods, technologies and conceptual models, for different geological settings, to identify suitable conditions for geothermal resource exploitation, tackling the issue of data scarcity and leveraging the information available. The proposals are expected to contribute to the assessment of environmental and social impacts and to unlock geothermal resources marked by low natural permeability at depths between 2000-6000m. The scope covers advances beyond the state of the art in equipment, methods and models capable of providing in-depth understanding and predictive power for properties and processes beyond conventional depths. The proposals are expected to take into account the impact of reservoir conditions and parameters (i.e. in-situ stress, temperature, geo-mechanical, chemical properties) on the development and performance of the geothermal resources, covering, when relevant, aspects such as the suitability for different stimulation techniques, well designs and completion technologies, the possibilities for the coproduction of raw materials, wellbore stability. The proposals are expected to validate the benefit of the proposed solution in the context of state-of-the-art decision and risk analysis methods. To ensure trust building and communities’ support, partners are expected to practice inclusive societal engagement, which is early, continuous, and sensitive to the technical specificities (e.g. impact on biodiversity, water balance, pollution, land occupation, visual impact, noise as well as geo-mechanical changes (e.g. seismicity) and underground changes (e.g. disturbance of non-targeted aquifers)) that could affect local communities and ecosystems [1] . This topic requires the effective contribution of SSH disciplines and the involvement of SSH experts, institutions as well as the inclusion of relevant SSH expertise, in order to produce meaningful and significant effects enhancing the societal impact of the related research activities. Technology Readiness Level - Technology readiness level expected from completed projects Activities are expected to achieve TRL 4-5 by the end of the project – see General Annex B. Activities may start at any TRL.

Destination
This Destination includes activities targeting a sustainable, secure and competitive energy supply. In line with the scope of cluster 5, this includes activities in the areas of renewable energy; energy system, grids and storage; as well as Carbon Capture, Utilisation and Storage (CCUS). This Destination contributes directly to the Strategic Plan’s Key Strategic Orientations ‘ Green transition ’, ‘ Digital transition ’ and ‘ A more resilient, competitive, inclusive and democratic Europe ’. In line with the Strategic Plan, the overall expected impact of this Destination is to contribute to the ‘Ensuring more sustainable, secure and competitive energy supply through solutions for smart energy systems based on renewable energy solutions’ . This destination contributes to the activities of the Strategic Energy Technology Plan (SET Plan) and its implementation working groups. The main impacts to be generated by topics under this Destination are: Renewable energy Energy producers have access to efficient and competitive European renewable energy and renewable fuel technologies with a solid knowledge base and are able to deploy them to enhance the EU’s energy security and reach its climate neutrality objectives, in a sustainable way in environmental (e.g., biodiversity, multiple uses of land and water, natural resources, pollution) and socioeconomic terms, and in line with the Sustainable Development Goals. Technology providers have access to European, competitive, resilient, reliable, sustainable, and affordable value chains of renewable energy and renewable fuel technologies including emerging ones, and with strong export potential to supply both the EU internal and global markets. They benefit also from circular renewable energy technologies that are safe and sustainable by design with reduced and diversified external dependence on critical raw materials [1] . Economic sectors benefit from better integration of renewable energy and renewable fuel-based solutions that are, among others, competitive, cost-effective, efficient, flexible, reliable, and sustainable. Such integration is facilitated through digitalisation and integration of artificial intelligence of renewable energy technologies that provide network stability and reliability. European industries benefit from a reinforced export potential of renewable energy and renewable fuel technologies, also through international partnerships, and become more competitive in innovative renewable energy technologies in Europe and globally. European researchers benefit from a stronger community and from a reinforced scientific basis on renewable energy and renewable fuel technologies including emerging ones, also through international collaborations. European citizens have access to an energy market that is fair and equitable, more resilient, uses all different types of local renewable energy resources, and is less dependent on fossil fuels imports. Citizens experience less fuel and energy poverty, and also benefit from new employment and upskilling opportunities. Local communities benefit from a more decentralized, affordable, and secure energy system and from multiple uses of land and water. Energy systems, grids and storage R&I actions will support the just digital and green transformation of the energy system through advanced solutions for accelerating the energy systems integration and decarbonisation . The developed clean, sustainable solutions will contribute to making the energy system work better for actors and supply more reliable, resilient and secure energy – even under increasingly more frequent extreme climate events. The solutions developed will contribute to increase flexibility and grid hosting capacity for renewables through optimizing cross sector integration and grid scale storage as well as cover off-grid situations. They will improve the preparedness of the electricity system to support the EU's binding target for 2030 of minimum of 42.5% renewables in the gross final energy consumption (with the aspiration to reach 45%), and full decarbonisation by 2050. They will enable further electrification of demand and will enhance the competitiveness of the European value chain , reduce pressure on resources (also by making technologies ‘circular by design’) and decrease dependencies. Such solutions would also enable a better EU resilience to climate risks. The solutions will improve consumer awareness and engagement in the energy transition, via innovative offers and services (e.g. demand response, energy communities) and will target different types of consumers, including “hard to reach” population groups (such as energy poor or low-income households). This will result in increased trust in, and uptake of the new products and services entering the energy system. Carbon capture, use and storage (CCUS) and carbon dioxide removal (CDR) Accelerated deployment of carbon capture, use and storage (CCUS) as a CO2 emission mitigation option in electricity generation and/or in industry applications, as well as carbon dioxide removal for negative emissions.
