In context of Horizon Europe

This grant€4.5M
The track runs to the largest grant in Horizon Europe (€171M). The median across the 482 calls we publish is €5.3M, this one is below it.

What this call funds

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.

These are Bemzu's estimates from the call's structure (the number of stages and whether a consortium is required) not figures published by the Commission. Only the co-financing share is read from the call itself.

Where these conditions come from

Two kinds of row. Most are the sentence we read the condition from, quoted out of the call itself. Some say plainly that they are not a quotation but the programme's own rule for this type of action, the EU portal publishes a table of contents where the conditions should be, so for a Research and Innovation Action the rate comes from the rulebook rather than from the fiche.

ConditionQuoted from the call, or the rule behind it
Consortium sizeNot quoted from this call — Research and Innovation Actions under the Horizon Europe rules are at least three independent legal entities from three different Member States or Associated Countries, at least one established in a Member State.
Funding rateNot quoted from this call — Research and Innovation Actions under the Horizon Europe rules are funded at 100% of eligible costs for every participant.
MaturityTechnology 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.
