Overview
Horizon Europe Cluster 4 „Digital, Industrie und Raumfahrt" ist eine der größten nicht verwässernden Förderquellen Europas für Hardtech: künstliche Intelligenz, Daten, Robotik, fortschrittliche Fertigung, Kreislauf- und saubere Industrie, Halbleiter, Internet der nächsten Generation, Rohstoffe und Raumfahrtsysteme. Es gehört zu Säule II von Horizon Europe, dem Vorzeige-Forschungsprogramm der EU. Das im Dezember 2025 verabschiedete Arbeitsprogramm 2026-2027 verfügt allein für Cluster 4 über rund 1,5 Milliarden Euro. Die Förderung erfolgt zu 100 % als Zuschuss, ohne Beteiligung und ohne Rückzahlung: Forschungs- und Innovationsmaßnahmen (RIA) werden zu 100 % der förderfähigen Kosten gedeckt, Innovationsmaßnahmen (IA) zu 70 % für Unternehmen. Einzelne Projekte erhalten in der Regel 2 bis 5 Millionen Euro, verteilt auf ein länderübergreifendes Konsortium aus mindestens drei Organisationen aus drei verschiedenen Ländern, wobei strategische Leuchtturmprojekte weit darüber hinausgehen. Unternehmen wie SALTO, das wiederverwendbare Trägerraketen-Technologie entwickelt, und QSNP, das ein europaweites quantensicheres Kommunikationsnetz aufbaut, gingen diesen kollaborativen Weg, ebenso wie das EROSS-IOD-Team, das die robotergestützte Wartung von Satelliten im Orbit demonstrierte. Der rote Faden ist Hardtech mit klarem strategischem Nutzen für die EU, entwickelt mit Partnern statt im Alleingang.
Seien Sie ehrlich zu sich selbst, was die Erfolgsaussichten angeht.
Is this for you?
- Consortium of 3+ organisations from 3+ EU/associated countries
- Universities, research institutes, SMEs and large companies all eligible
- Project matches a named topic in digital, industry, space or raw materials
- TRL 2–6 for research actions (RIA), TRL 5–8 for innovation actions (IA)
- At least one partner based in an EU Member State
- Lone startup that wants to apply solo → EIC Accelerator
- Seeking equity investment alongside the grant → EIC Accelerator (blended finance)
- Breakthrough idea that fits no published topic → EIC Pathfinder Open
- Single-country national project → your national innovation agency
Associated countries (UK, Norway, Israel and others) count toward the three-country minimum, but the consortium must include at least one EU Member State partner. Calls are topic-driven: if your project does not match a topic text in the Work Programme, evaluators will score it down no matter how good it is.
Call destinations
Manufacturing 4.0, circular economy, digital twins for industry
Semiconductors, advanced materials, raw materials, batteries
AI, data, cloud, IoT, next-gen internet, HPC
Digital health, creative industries, cultural heritage
Earth observation, navigation, secure connectivity
Open science, technology transfer, standards
Success rates — the honest picture
Roughly 1 in 6 applications gets funded. A sharp, evidence-backed proposal is what separates the funded from the rejected.
| Call | Submitted | Funded / passed | Rate |
|---|---|---|---|
| 2024 single-stage | 382 | 46 funded | 12.0% |
| 2024 two-stage (final) | 239 | 15 funded | 6.3% |
| 2025 single-stage | 639 | 72 funded | 11.3% |
| 2025 two-stage, stage 1 | 243 | 59 passed to stage 2 | 24.3% |
Two-stage maths: roughly 24% pass stage 1, then about one in four stage-2 proposals gets funded — around 6% end to end. Single-stage odds of 11–12% beat EIC Pathfinder's ~2%. There is no resubmission penalty: rejected consortia can revise and resubmit to the next call, and many winners are second attempts. The 2025 Space call was the outlier at 30% (27 of 90 eligible proposals, €138.6M).
Eligibility
- 1Sie benötigen ein Konsortium aus mindestens drei unabhängigen Rechtsträgern mit Sitz in drei verschiedenen EU-Mitgliedstaaten oder mit Horizon assoziierten Ländern; ein einzelnes Unternehmen kann nicht im Alleingang gewinnen.
- 2Der Koordinator (der Partner, der die Finanzhilfe einreicht und verwaltet) muss in einem EU-Mitgliedstaat ansässig sein, nicht nur in einem assoziierten Land.
- 3Jeder Rechtsträger ist unabhängig von der Größe teilnahmeberechtigt: Start-ups, KMU, Großindustrie, Universitäten, Forschungsinstitute und öffentliche Einrichtungen sind alle förderfähig, und die meisten erfolgreichen Konsortien mischen all diese.
- 4Ihr Antrag muss auf ein bestimmtes offenes Thema im Cluster-4-Arbeitsprogramm reagieren und die für dieses Thema aufgeführten erwarteten Ergebnisse treffen; eine hervorragende Idee, die zu keinem offenen Thema passt, ist automatisch außerhalb des Anwendungsbereichs.
- 5Ihre Technologie muss etwa bei TRL 3-7 liegen (im Labor validiert bis hin zur Demonstration in einer relevanten Umgebung); reine Grundlagenforschung und marktreife Produkte passen beide schlecht.
- 6Antragsteller aus dem Vereinigten Königreich sind nun als assoziiertes Land teilnahmeberechtigt, prüfen Sie jedoch die jeweilige Ausschreibung, da eine Handvoll Themen, die an strategische Vermögenswerte gebunden sind, Sicherheitsbeschränkungen für die Teilnahme von Nicht-EU-Akteuren mit sich bringen.
Cluster 4 runs on the standard Horizon Europe rule: at least three independent legal entities from three different countries, of which at least one in an EU Member State and two more in Member States or associated countries. A brilliant solo SME (small or medium-sized enterprise) cannot apply alone — unless a specific topic says otherwise, single-applicant proposals are inadmissible. Affiliates of the same group do not count as independent.
Cluster 4 is the cluster where the EU guards its 'open strategic autonomy'. A subset of space topics — notably EU non-dependence work on EEE (electrical, electronic and electromechanical) components and in-space operations — is restricted to entities established in the EU/EEA, shutting out all other countries, associated or not. Restrictions can also bite entities established in an eligible country but controlled, directly or indirectly, from a non-associated third country. The lockout is topic-by-topic: always read the 'specific conditions' block of your topic before assembling a consortium.
The UK is associated to Horizon Europe since 1 January 2024 and participates in everything except the EIC (European Innovation Council) Fund equity arm. Switzerland is associated retroactively from 1 January 2025 under the EU Programmes Agreement signed in November 2025, with confirmed access to Cluster 4's strategic areas — AI, quantum, communication networks and space — in the 2026–2027 work programme. Caveat: where a topic is restricted to Member States or EU/EEA entities under Article 22(5), associated-country status does not help.
If the requested EU contribution for the action is €500,000 or more, the coordinator's financial capacity is formally verified (public bodies and most universities are exempt). A private coordinator with thin equity or no closed accounts — typical of a newly created company — risks being asked for guarantees or told to hand coordination to a sturdier partner. The Commission can also extend the check to other beneficiaries where it sees risk.
Topics flagged as security-sensitive — common across Cluster 4's space, quantum and advanced-computing strands — undergo a security appraisal on top of the ethics review every proposal faces. Outcomes range from security requirements written into the grant agreement to classification of deliverables, and in extreme cases a proposal can be dropped. Budget time for it: the screening sits between evaluation and grant signature and can slow grant preparation.

The money — consortium grants, no equity
Cluster 4 pays grants split across a consortium — the EU takes no shares and asks for no repayment. Research and Innovation Actions (RIA, early-stage research) reimburse 100% of eligible costs for everyone. Innovation Actions (IA, prototyping and demonstration) reimburse 70% for for-profit companies and 100% for non-profits. Coordination and Support Actions (CSA, networking and policy work) pay 100%, typically €0.5M–€4M.
If you are a company in an IA, you cover 30% of your own costs from your own pocket. A €1M work package means €700K from Brussels and €300K from you. Budget for it before you sign up — it is the most common nasty surprise for first-time industrial partners.
A growing share of 2026–2027 topics use lump-sum grants: the budget is fixed per work package and paid when the work package is completed — no timesheets, no financial audits, no cost reporting. The catch: a half-finished work package earns nothing until it is done. Check the topic page on the Funding & Tenders Portal to see which regime applies.
The Commission pays a pre-financing instalment shortly after signature, then interim and final payments against periodic reports. All money flows through the coordinator, who distributes it to partners under the consortium agreement — negotiate that agreement carefully before the project starts.

Pre-financing is paid within 30 days of the grant agreement entering into force or 10 days before the action's start date, whichever is later — the first real money in the project account.
After you're funded
Funded projects are managed by HaDEA (the European Health and Digital Executive Agency), which assigns a project officer to each grant. They approve reports, sign off on amendments and are your single point of contact with Brussels for 24–48 months — most RIAs run 36 months.
Pre-financing arrives shortly after the grant agreement is signed, then interim payments follow each approved periodic report (every 12–18 months) and a final payment closes the project. Actual-cost grants above €430K per beneficiary need a certificate on financial statements from an auditor; lump-sum projects skip cost audits entirely.
Periodic technical and financial reports every 12–18 months, a data management plan, open-access publication of results, and a dissemination and exploitation plan you are contractually bound to deliver. Budget real person-months for this — it is not a formality.
Intellectual property, access rights between partners, money distribution and what happens when a partner underdelivers are all set in the consortium agreement, not the grant agreement. Sign it before the project starts, ideally before submission.
There is no resubmission limit or penalty in Cluster 4. Take the Evaluation Summary Report, fix what the three independent evaluators flagged, and come back to the next call — second-attempt proposals routinely win.
Practical notes
Cluster 4 spans Digital, Industry and Space, and each strand has its own dedicated EU-wide National Contact Point network with its own free brokerage and partner-search tools: Ideal-ist for Digital, NCP4Industry+ (coordinated by APRE) for Industry, and COSMOS4HEplus for Space. Identify which one owns your topic and contact your national NCP through that network rather than a generic helpdesk.
The thematic NCP networks offer applicants free services such as project-idea checks, partner-search facilitation, brokerage events and full draft-proposal reviews. Ideal-ist in particular runs a proposal check service free of charge, where experienced external experts and NCPs give written feedback to improve quality before submission — a genuine odds-mover that most applicants never use.
The Commission's Cluster 4 Info Days for the 2026 Work Programme ran online on 29-30 January 2026 (Day 1 Industry and Space, Day 2 Data, Digital, Human and Horizontal), and are paired with free B2Match matchmaking platforms: the Industry Brokerage Event ran 12 January-17 April 2026 with a pitching session on 10 February, and a Space Brokerage Event was held on 5 February 2026. Registration is mandatory but free; recordings of Info Days are published afterwards.
A large share of Cluster 4 topics flow from co-programmed public-private partnerships — Made in Europe, Processes4Planet (A.SPIRE), AI-Data-Robotics, Photonics, Clean Steel — whose Strategic Research and Innovation Agendas feed directly into which topics appear and how they are worded. Engaging early with the relevant partnership association (e.g. joining EFFRA for Made in Europe) gives you visibility into the agenda and access to its consortium-building network before topics are even published.

Frequently Asked Questions
Jeder Rechtsträger kann teilnehmen: Unternehmen jeder Größe, Universitäten, Forschungsinstitute und öffentliche Einrichtungen. Die meisten Ausschreibungen erfordern ein Konsortium aus mindestens drei unabhängigen Organisationen aus drei verschiedenen EU-Mitgliedstaaten oder mit Horizon assoziierten Ländern. KMU und Start-ups schließen sich in der Regel einem größeren Konsortium an, statt sich allein zu bewerben, was für eine Gründerin oder einen Gründer der realistische Weg ist.
Cluster 4 ist zu 100 % Zuschussgeld, ohne Beteiligung und ohne zurückzuzahlenden Kredit. Forschungs- und Innovationsmaßnahmen (RIA) werden zu 100 % der förderfähigen Kosten gefördert und Innovationsmaßnahmen (IA) zu 70 % für Unternehmen (100 % für gemeinnützige Einrichtungen). Einzelne Projekte erhalten in der Regel zwischen rund 2 Millionen und 5 Millionen Euro, verteilt auf das gesamte Konsortium, wobei sehr große Themen darüber hinausgehen.
Für nahezu alle Cluster-4-Themen ja. Die Standardregel sind mindestens drei unabhängige Rechtsträger mit Sitz in drei verschiedenen EU- oder assoziierten Ländern, und der Koordinator muss in einem EU-Mitgliedstaat ansässig sein. Ein typisches erfolgreiches Konsortium hat 6 bis 12 Partner, die Industrie, Forschung und Endnutzer vereinen, sodass ein einzelnes Start-up nicht im Alleingang gewinnen kann.
Das Arbeitsprogramm 2026-2027 wurde am 11. Dezember 2025 verabschiedet und eröffnete Anfang 2026 fünf große Ausschreibungen. Stand Juni 2026 bleiben drei bevorstehende Fristen offen: Die Raumfahrt-Ausschreibung (HORIZON-CL4-2026-03, 90,97 Millionen € über 8 Themen) endet am 3. September 2026; die Ausschreibung zum Clean Industrial Deal (HORIZON-CID-2026-01, 125 Millionen €) endet am 15. September 2026; und Stufe 2 der zweistufigen Industrie-Ausschreibung (HORIZON-CL4-2026-02, 98 Millionen €, 3 Themen) endet am 13. Oktober 2026. Die große einstufige Industrie-Ausschreibung (HORIZON-CL4-2026-01, 319 Millionen €, 15 Themen, 21. April), beide Digital-Ausschreibungen (HORIZON-CL4-2026-04 mit 221,8 Millionen € und HORIZON-CL4-2026-05 mit 85,5 Millionen €, beide 15. April) sowie Stufe 1 der zweistufigen Industrie-Ausschreibung (17. März) sind für 2026 nun geschlossen.
Es ist hart umkämpft. Horizon Europe insgesamt liegt bei einer Erfolgsquote von etwa 12 % bis 16 %, wobei die Ausschreibungen um das rund Vier- bis Fünffache des verfügbaren Budgets überzeichnet sind. Einstufige Ausschreibungen verlangen von Anfang an einen vollständigen, ausgefeilten Antrag, während zweistufige Ausschreibungen Ihnen eine kürzere erste Runde (mit höherer Trefferquote) ermöglichen, bevor Sie den vollständigen Antrag einreichen.
Kalkulieren Sie mit 2 Millionen bis 5 Millionen € verteilt auf ein Konsortium und planen Sie Zeit ein. Die Kommission strebt an, Sie innerhalb von etwa 5 Monaten nach der Frist über das Ergebnis zu informieren, gefolgt von rund 3 Monaten Vorbereitung der Finanzhilfevereinbarung, sodass die Standard-Zielzeit bis zur Finanzhilfe bei etwa 8 Monaten liegt. Die Vorfinanzierung (oft 60 % bis 80 % des EU-Beitrags) wird in der Regel kurz nach Unterzeichnung der Finanzhilfe gezahlt.
Wählen Sie ein Thema und lesen Sie den Ausschreibungstext wörtlich, denn jedes Thema hat bestimmte erwartete Ergebnisse, die Sie treffen müssen. Anträge werden in Exzellenz (Excellence), Wirkung (Impact) und Umsetzung (Implementation) bewertet, jeweils mit bis zu 5 Punkten, und die Wirkung ist der Bereich, in dem die meisten Anträge scheitern, also beziffern Sie Markt, Arbeitsplätze und strategischen Nutzen für die EU. Ein glaubwürdiges Konsortium mit klaren Rollen, ein realistischer Arbeitsplan und ein echter Weg zur Markteinführung schlagen eine stärkere, aber vage beschriebene Idee.
