Resource assessment for deep sedimentary and basement reservoirs

This is a Horizon Europe grant opportunity titled "Resource assessment for deep sedimentary and basement reservoirs" under the call HORIZON-CL5-2026-11-D3-06. It falls under the type of action known as Research and Innovation Actions (HORIZON-RIA) and will use a lump sum grant funding mechanism (HORIZON Lump Sum Grant). The call is set to open on August 4, 2026, with a deadline for applications on December 1, 2026. The total funding available for this call is €18,000,000, divided into four grants of €4,500,000 each.

Eligible applicants include legal entities based in EU Member States and associated countries, such as universities, research institutes, companies (including SMEs), and other legal entities that demonstrate the required operational and financial capacity. The grant encourages consortium applications, requiring at least three partner organizations from different countries.

The focus of the call is on the assessment of geothermal resources, particularly in deep sedimentary and basement reservoirs. Projects should develop methods for identifying geothermal resources and enhancing geothermal systems, addressing challenges like data scarcity and environmental impact. This includes considerations of sustainability, social engagement, and impacts on local communities and ecosystems.

The projects should target Technology Readiness Levels (TRL) 2-6, suggesting a mix of development, validation, and demonstration activities. The funding will cover 100% of eligible costs without a co-funding requirement. The submission process is straightforward, with applicants required to submit full proposals in a single stage rather than in multiple phases.

While specific success rates for this grant have not been mentioned, Horizon Europe generally exhibits competitive success rates ranging between 10% and 39%. The application process involves creating profiles in the Funding and Tenders Portal, followed by the submission of detailed proposals during the specified timeline.

The overarching aim of this call is to enhance scientific and technical knowledge in geothermal energy, contributing to Europe's clean energy transition by advancing exploration techniques and methodologies. Successful proposals will also be expected to consider socio-economic impacts and engage local communities to ensure support for geothermal energy initiatives.

This is a Horizon Europe call focusing on resource assessment for deep sedimentary and basement reservoirs to unlock unexploited geothermal resources. The call, ENERGY (HORIZON-CL5-2026-11), is part of the Horizon Europe (HORIZON) program. The type of action is HORIZON-RIA (Research and Innovation Actions), utilizing a HORIZON Lump Sum Grant [HORIZON-AG-LS] Model Grant Agreement (MGA). The deadline model is single-stage, with a planned opening date of August 4, 2026, and a deadline of December 1, 2026, at 17:00:00 Brussels time.

The expected outcome of the projects funded under this call is to increase the knowledge base for developers to unlock unexploited geothermal resources, increase drilling success rate, increase geothermal sources performance, reduce the risk of induced seismicity, and deploy geothermal energy in a sustainable way in environmental (notably on biodiversity and pollution) and socioeconomic terms. The projects should also ensure that citizens and local communities are engaged and benefit from local, more secure, and affordable renewable energy sources.

The scope of the call includes 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. 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, and 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. This topic requires the effective contribution of SSH (Social Sciences and Humanities) disciplines and the involvement of SSH experts and institutions to produce meaningful and significant effects enhancing the societal impact of the related research activities.
