Typed facts extracted from the source documents by Scindu's grant-data review. Each value keeps its own conditions. Unknown means unstated, not zero or unlimited.

Consortium required

Yes

Unless the exact topic-specific conditions provide otherwise, this action requires three independent beneficiary legal entities established in three different countries: at least one in an EU Member State and at least two others in different EU Member States or Associated Countries. Affiliated entities do not count toward the minimum. Topic-specific required organisation types, applicant restrictions, and exceptions recorded elsewhere in this packet remain applicable; this baseline does not replace them.

Other condition

The Work Programme specifies Innovation Action as the action type for this topic.

Other condition

Selected projects are expected to contribute to the BRIDGE initiative and actively participate in its activities.

Other condition

Entities established in eligible countries but directly/indirectly controlled by China (or China-established legal entities) cannot participate where the topic invokes the critical-technology restriction.

Other condition

Improve energy security by adding cost-effective, efficient and flexible storage capacity; improve sustainability and circularity of storage; and use existing infrastructure to enhance economic viability.

Other condition

Technology Activities are expected to achieve TRL 6-8 by the end of the project – Readiness Level see General Annex B. Activities may start at any TRL.

Other condition

Work Programme call table lists an indicative EU contribution of around EUR 7,500,000 per project and an indicative 3 project(s) expected to be funded. The amount and count are indicative, not guarantees or hard recipient caps.

Other condition

Where satellite data/services are used, beneficiaries must use Copernicus and/or Galileo/EGNOS; other services may also be used.

Other condition

Demonstrate novel or improved cost-efficient, circular, sustainable energy storage that contributes to grid flexibility and uses obsolete/outdated energy or other infrastructure. Integrate storage technologies and retrofitting, optimise storage capacity/efficiency/circularity and socioeconomic/environmental sustainability (e.g. stakeholder outreach and environmental impacts), and use secure-by-design. Selected projects are expected to contribute to BRIDGE.

Technology readiness level at end, maximumExpected end-of-project target upper endpoint, not a hard maximum

8 TRL level

Work Programme wording is “expected to achieve”; activities may start at any TRL. This is an expected target range, not a prohibited higher result.

Technology readiness level at end, minimumExpected end-of-project target lower endpoint, not a mandatory minimum at project end

6 TRL level

Work Programme wording is “expected to achieve”; activities may start at any TRL. The endpoints are not hard grant eligibility thresholds.

Indicative budget

€22,500,000

Topic budget as stated in the portal's budget table. Lump-sum and per-project limits are in the call conditions.

Eligible cost limit

25 percent flat rate of eligible direct costs, subject to the base exclusions in conditions

Horizon Europe General Annex G describes a 25% indirect-cost flat rate on eligible direct costs, excluding eligible direct subcontracting costs, financial support to third parties, and any unit costs or lump sums that include indirect costs. For HORIZON-AG actual-cost grants this is a cost-calculation rule, not a grant-rate increase. For HORIZON-AG-LS it informs the underlying eligible-cost estimate only; it is not an additional payment on top of the fixed lump sum. The topic indicative allocation and per-project contribution are distinct from this cost rate.

Funding intensity, maximum

70 percent of eligible costs (general Innovation Action maximum for non-profit status not established)

The exact Work Programme labels this topic an Innovation Action. General Annex G sets a 70% maximum for legal entities other than non-profit entities; the separate nonprofit maximum is represented in its own typed fact. This is an action-type maximum, not a guarantee or the topic-level indicative EU contribution; the final rate is fixed in the grant agreement. For the lump-sum topics, the rate is already applied in the lump-sum methodology and is not an extra multiplier.

Funding intensity, maximum

100 percent of eligible costs (up to; nonprofit legal entities only)

Only for a non-profit legal entity, the general Innovation Action maximum may be up to 100%; this is not automatic or a salary entitlement, and final funding parameters are fixed in the grant agreement. For the lump-sum topics, the percentage is embedded in the lump-sum amount methodology and is not an extra multiplier.

Expected contribution per projectCommission-estimated EU contribution per project for this exact topic

€7,500,000

The Work Programme says this amount would allow outcomes to be addressed appropriately but expressly does not preclude proposals requesting other amounts. It is not a minimum, maximum or award promise.

Topic allocationExact Work Programme topic allocation, not per-project funding

€22,500,000

The call table marks the budget indicative and subject to availability of Union appropriations; it is not a guaranteed grant or per-beneficiary amount.

• Other role

  Staff cost the grant can fund

  These are underlying personnel-cost estimate categories only where eligible in the applicable lump-sum methodology; they do not mean separate actual-payroll reimbursement. The source does not establish vacancies, salary amounts, headcount, or hiring decisions. MGA A.2/A.3 requires assignment to the action, employee-like working conditions, result ownership by the beneficiary unless otherwise agreed, and a rate based on actual incurred costs not significantly different from similar employee tasks.

• Other role

  Staff cost the grant can fund

  These are underlying personnel-cost estimate categories only where eligible in the applicable lump-sum methodology; they do not mean separate actual-payroll reimbursement. The source does not establish vacancies, salary amounts, headcount, or hiring decisions. MGA A.1 covers personnel working for the beneficiary under an employment contract or equivalent appointing act and assigned to the action; salary components follow Article 6.2 A.1.

• Other role

  Staff cost the grant can fund

  These are underlying personnel-cost estimate categories only where eligible in the applicable lump-sum methodology; they do not mean separate actual-payroll reimbursement. The source does not establish vacancies, salary amounts, headcount, or hiring decisions. Only SME owners not receiving a salary or natural-person beneficiaries not receiving a salary are covered; declared as Annex 2a unit costs, subject to general eligibility conditions.
