Scope
Expected Outcome: Project results are expected to contribute to all the following expected outcomes: Improved energy security of the energy system by offering cost-effective and efficient solutions for additional diverse and flexible energy storage capacities. Improve the sustainability and circularity of energy storage systems. Enhanced economic viability of energy storage by utilizing existing infrastructures. Scope: Demonstration of novel or improved technological solutions for cost-efficient, circular and sustainable energy storage, which contribute to grid flexibility and make use of existing obsolete or outdated energy or other infrastructures. Proposals should integrate the synergies between novel or improved energy storage technologies and retrofitting of obsolete or outdated infrastructures, like e.g. old hydropower dams and basins, decommissioned power plants, former industrial facilities, coal mines, fossil fuel infrastructure etc. by optimizing at the same time storage capacity and efficiency as well as circularity and socioeconomic and environmental sustainability, which should be addressed, e.g. by stakeholder outreach and consideration of possible environmental impacts. Furthermore, proposals should follow secure by design approach and integrate built-in security in the energy systems. Selected projects are expected to contribute to the BRIDGE initiative [1] and actively participate in its activities. Technology Readiness Level - Technology readiness level expected from completed projects Activities are expected to achieve TRL 6-8 by the end of the project – see General Annex B. Activities may start at any TRL. [1] https://bridge-smart-grid-storage-systems-digital-projects.ec.europa.eu/

The mix of organisations
Who coordinated them
Coordinating an EU project is a demanding, specific job. These organisations have done it on this topic line before.
This is the shape, not the consortium. It says how many partners these projects had and what kinds of organisation were in them. It does not know whether your idea needs the same mix, who is available, who is already committed elsewhere, or how the work and the budget should be divided. Those are judgement calls on a specific proposal, and no amount of public data answers them.
Building the actual consortium — finding the partners, agreeing the roles, and writing it so it survives an evaluation — is what Scientific Network Management does. Free either way; the radar does not change if you never ask.
Get told when something changes
Most institutions find out about a call with three weeks left. We write when something opens, moves or closes that fits what you work on, with the deadline, the fit and the funder's own exclusion clauses quoted. Nothing in a quiet week. Free, and one click to leave.
Starting from the programme you are reading: Horizon Europe (HORIZON) — change it below if you like.
Leave the second box empty and you get whatever opened or changed recently, closing soonest. Fill it in and it ranks against your words instead: that is the difference between a list and a shortlist.
Scientific Network Management will send you the current list for these terms, and after that only what changes: a call that opens, a deadline that shifts, a clause that rules you out. Nothing is sent when nothing has moved. One click to stop, in every message.
One confirmation email and nothing else until you click it. No tracking pixels, no sharing, one click to unsubscribe.
Of every 100 Horizon Europe proposals
A funding strategy reads your institution's own published record against the calls that are open, and says in writing which are worth the year and which to decline, with the reason for each.
Scientific Network Management, the grant-writing practice behind this radar: 13 years of EU-funded research projects, and a founder who has served as Key Expert and Team Leader on two EU-funded technical assistance contracts establishing biotechnology centres in Türkiye.
SNM also does
No obligation, and nothing here is conditional on using us: searching the calls stays free and asks for nothing either way.
