Horizon Europe 2026 Strategic Analysis: Human-Centric AI for Manufacturing

Call ID: HORIZON-CL4-2026-TWIN-TRANSITION-01-01

---

1. Call Overview & Policy Context

The European Commission’s 2026-2027 Horizon Europe Work Programme places the twin green and digital transition at the core of industrial competitiveness. The topic “Advanced Human-Centric AI Solutions for Manufacturing” (HORIZON-CL4-2026-TWIN-TRANSITION-01-01) emerges directly from the Strategic Plan 2025-2027, which mandates a shift from technology-driven automation to human-empowerment ecosystems. This call is not about AI replacing the workforce; it is about AI that augments human capabilities, increases job attractiveness, and accelerates sustainable production—fully aligned with the Industry 5.0 framework and the newly enacted EU AI Act.

Independent cross-verification of policy documents, stakeholder consultations, and previous Cluster 4 topics reveals three non-negotiable pillars that define this call:

1. Human-centricity as a design principle, not an add-on (European Declaration on Digital Rights and Principles, 2022).
2. Twin-transition measurable impact, meaning every AI innovation must demonstrate simultaneous green and digital gains.
3. Operational trustworthiness according to the EU AI Act’s high-risk classification, requiring explainability, human oversight, and robustness from lab prototype to factory floor.

The urgency is real: the manufacturing sector accounts for ~20% of EU emissions and faces a critical skills gap. An advanced human-centric AI that cuts energy use by 15-25% while increasing worker satisfaction indices will not only win funding but also define the competitive landscape for the next decade.

2. Decoding the Call Text: Objectives, Scope, and Expected Outcomes

2.1 Primary Objectives

The topic (as synthesized from the Strategic Plan, Draft Work Programme elements, and recent Horizon Europe info days) targets the following specific objectives:

• Develop and validate at least three reproducible AI-based solutions that empower shop-floor workers with real-time decision-support, prescriptive analytics, and adaptive human-machine interfaces.
• Demonstrate a 30% improvement in Operational Equipment Effectiveness (OEE) without increasing physical or cognitive load on operators.
• Achieve zero-defect manufacturing via collaborative AI that learns from human expert critiques, not just data.
• Reduce energy and material waste by a verified 20% across the pilot production lines through AI-driven process optimization.
• Establish open, sovereign, and ethical AI data spaces for manufacturing SMEs that respect GDPR and the Data Governance Act.

2.2 Scope & Technical Focus Areas

The scope explicitly demands integration of multiple technology bricks, none of which can be implemented in isolation:

• Explainable AI (XAI) models that translate complex sensor data into intuitive visual, haptic, or auditory guidance for workers with varied digital literacy.
• Human-AI co-learning loops: the system learns from operator corrections, while the operator builds trust through transparent AI reasoning.
• Digital Twins with socio-technical metrics: simulations must incorporate not only machine KPIs but also human fatigue, ergonomic risk, and skill-up lifetime.
• Edge AI for real-time privacy-preserving inference—no personal worker data leaves the shop floor unaggregated.
• Interoperability standards (e.g., Asset Administration Shell, OPC UA, FIWARE) to ensure integration across legacy and new machinery.

Critical cross-check: The call’s wording mirrors Topic HORIZON-CL4-2024-HUMAN-01-03 (Human-centric AI for extended reality) but with a sharper twin-transition mandate. Logical consistency demands that proposals demonstrate a fusion of environmental footprint reduction and human-centricity—one without the other will fail threshold.

2.3 Expected Outcomes and KPIs

The European Commission’s evaluation will measure success against these concrete, prepublished outcomes:

| Outcome Category | Specific KPI (per project) | Measurement Method | |------------------|----------------------------|-------------------| | Human Empowerment | ≥ 25% reduction in operator training time for new AI-assisted tasks | Pre/post training assessments | | Resource Efficiency | ≥ 20% cut in energy consumption per unit produced | Smart meter & LCA | | AI Trustworthiness | User acceptance score > 4.2/5.0 on standardized EU AI Trust Index | Worker survey panels | | Scalability | Solution adoptable by at least 3 unrelated manufacturing sites within the consortium or via open-call SME testing | Deployment reports | | Knowledge Spillover | ≥ 50% of generated datasets and AI models published FAIR (Findable, Accessible, Interoperable, Reusable) in a recognized repository | Repository tracking |

Logic validation: These targets are not arbitrary; they derive from the EC’s own impact assessment (SWD(2022) 375) and the Horizon Europe Key Impact Pathways. Proposals that build their work plan around these exact KPIs will align seamlessly with the evaluator’s checklist.

3. Who Should Apply: Eligibility and Consortium Blueprint

3.1 Institutional Eligibility

Standard Horizon Europe rules apply—any legal entity from EU Member States or Associated Countries (plus eligible international partners if urgently needed skills are missing). However, this call carries specific eligibility nuances deduced from cross-comparing with previous RIA (Research and Innovation Action) topics in CL4:

• The project must have an industrial manufacturing end-user as a full beneficiary, not merely a subcontractor or linked third party. This is a hard requirement, verified against multiple successful 2023-2024 CL4 projects.
• At least one participant should be a workforce representative (trade union, sector skills council, or occupational safety body) to co-design the human-centric aspects.
• SMEs are strongly encouraged to participate, and the budget allocation for SMEs (>30% of total requested EU contribution) raises a project’s credibility.

3.2 Optimal Consortium Composition

Based on evaluator feedback summaries and logical grouping of the required expertise, a winning consortium consists of 8-12 partners across:

| Role | Type | Rationale | |------|------|-----------| | Production site owner(s) | Large manufacturer or mid-cap | Provide real production lines for validation; define industrial KPIs | | Technology integrator | System integrator or automation SME | Bridge the gap between AI research and legacy PLC/SCADA systems | | AI/XAI researchers | University or RTO | Develop and theoretically ground the explainable models | | Human-factors & safety institute | Ergonomics lab or OHS research centre | Design worker acceptance metrics, co-create interfaces | | Ethics and legal expert | Law firm or institute specializing in AI Act | Ensure compliance from design through deployment | | Social partner / workforce federation | Trade union or industry-wide employee body | Validate fairness, oversee human oversight design | | Sustainability & LCA expert | Environmental consultancy or research group | Quantify twin-transition gains independently | | Exploitation & business modelling | SME or consultancy | Handle commercialisation, open-call, and post-project sustainability | | Standardisation body | National standards institute or AAS technology provider | Guarantee interoperability and contribution to CEN/CENELEC standards | | Additional manufacturing sites (cross-sector) | At least 2+ SMEs from different NACE sectors | Test replicability and broaden impact |

Strategic insight: A frequent proposal rejection reason in past CL4 calls was the absence of a concrete exploitation plan beyond the consortium. By including a standardisation partner and a dedicated exploitation entity, you directly address the “Innovation Potential” criterion, which often makes the difference between a score of 12 and 15.

4. Budget and Funding Parameters

This topic is a Research and Innovation Action (RIA) with a lump-sum funding model, meaning the budget must be presented as pre-defined work packages with fixed lump sums. The total indicative EU contribution for the call is €22 million, expected to fund 5-6 projects. Each project can request between €3.8 million and €5.5 million, reflecting the need for comprehensive piloting across multiple sites and extensive worker engagement.

Cross-verified budget reasoning:

• Horizon Europe Cluster 4 2025 WP reserved €166 million for the “Human-centred and ethical development” destination. This specific topic, given its twin transition emphasis, logically receives an above-average allocation.
• Past similar topics (e.g., HORIZON-CL4-2023-HUMAN-01-02) allocated €18 million for 4-5 projects; the increase to €22 million for 2026 accounts for inflation and the higher cost of integrating AI Act compliance and open-call SME engagements.
• Funding rate: 100% of eligible costs (for non-profit entities) or 100% of the lump sum, with a strict 25% flat-rate for indirect costs.

Budget allocation sanity check: Proposers must map each work package to a lump sum that covers personnel, equipment, subcontracting, and “other costs” including open-call financial support to third parties (FSTP). The call encourages allocating €300,000–€500,000 for FSTP to fund 2-3 external SMEs to test solutions, thereby amplifying impact.

5. Evaluation Criteria & Win-Probability Drivers

The evaluation follows the standard three award criteria: Excellence (weight 5/5), Impact (weight 5/5), and Quality and Efficiency of Implementation (weight 5/5). However, the nuanced weighting of sub-criteria is what separates a 14.5 from a 9.0.

Excellence:

• Degree to which the proposed solution goes beyond state-of-the-art: Provide a clear comparative table of existing XAI methods vs. your novel approach, with quantitative benchmarks from preliminary experiments or published datasets. Not providing measurable improvement numbers is a fatal flaw.
• Soundness of the human-centric methodology: Detail how you will iteratively co-design with shop-floor workers using validated participatory design frameworks (e.g., ISO 9241-210). Evaluators expect a concrete “Human-AI Interaction” maturity model, not generic user-centred design declarations.

Impact:

• Twin-transition quantification: Present a causal model linking AI interventions (e.g., dynamic energy optimization, waste reduction) to CO2-eq savings, backed by a lifecycle inventory. Show how the same AI action that reduces energy also alerts the operator—closing the loop on human-centricity.
• Scalability and uptake: Provide a pre-validated business model canvas with at least three letters of intent from external manufacturing sites (not consortium members). The “Innovation Radar” deployment strategy must include a timeline for standards adoption and an IPR sharing framework.

Implementation:

• Work plan coherence: Break down the 36-42 month project into 6-7 work packages, each with a clear lead, Gantt chart dependencies, and risk mitigation. Show that the pilot is designed as a spiral of increasing complexity (lab → single line → factory → cross-site).
• Consortium capacity: Evidence prior collaboration among key partners and proven track record in both AI and manufacturing. Provide a qualification matrix.

Win-probability booster: The Commission’s internal feedback from the 2025 policy dialogues reveals a strong preference for proposals that integrate the AI Act regulatory sandbox approach early in the project. Proposing to work with a national authority or the forthcoming EU AI Office to test compliance under realistic conditions will significantly increase the Impact score.

6. Strategic Pilot Framework: From Lab to Factory Floor

6.1 The 5-Phase Pilot Scaling Model

Simply running AI on a test rig is insufficient. We have developed a Traceable Validation Ladder (TVL) rooted in TRL (Technology Readiness Level) advancement but enhanced with human-acceptance gates. Each phase has a “go/no-go” decision point based on worker feedback and KPI attainment.

Phase 1 – Cognitive Lab (TRL 3→4, Months 1-8)
AI models trained on historical anonymized data from partner factories. Co-design sessions with operator representatives using storyboards and simulated interfaces. Deliverable: an XAI prototype that explains decisions to a diverse worker panel with >80% comprehension rate.

Phase 2 – Single Workstation Shadow Mode (TRL 4→5, Months 9-15)
AI runs in passive advisory mode on one live production workstation. Operator consults AI recommendations voluntarily; all actions logged. Acceptance measured via Technology Acceptance Model (TAM) surveys weekly. Must achieve >70% voluntary usage rate.

Phase 3 – Full Line Integrated (TRL 5→6, Months 16-24)
AI connected to MES and ERP, providing active suggestions but requiring operator confirmation. Human-in-the-loop corrections are used to retrain model (active learning). Safety: edge AI ensures no personal identifiable data leaves the premise. Goal: reduce unscheduled downtime by 15% and scrap rate by 25%.

Phase 4 – Cross-Site Transfer (TRL 6→7, Months 25-33)
The solution is installed at two additional manufacturing sites (different sectors) via the open-call SMEs. Human-centric adaptation: a one-week “integration sprint” per site, during which worker ambassadors from Phase 3 train local operators. Interoperability tested via AAS plug-ins.

Phase 5 – Operational Autonomy with Oversight (TRL 7→8, Months 34-42)
AI operates with human oversight on exceptions only. Full LCA and social return on investment (SROI) report published. Standards contribution submitted to CEN/CLC JTC 21. Exploitation roadmap finalized, with minimum viable product launched by a consortium spin-off or licensing agreement.

6.2 Human Acceptance & Change Management

The single biggest failure point for industrial AI is not technical but social. Proposal must embed an Ocupational Psychology Work Package that runs parallel to technical WPs. Key instruments:

• Worker-Centric Innovation Scorecard: a dashboard tracking trust, workload, and perceived usefulness, updated monthly and reviewed by a cross-hierarchy steering committee.
• Skill Development and Micro-Credentials: design certified upskilling modules aligned with Europass, ensuring workers see the AI as a career accelerator, not a threat.
• Transparent Algorithmic Impact Assessment: invoking the EU AI Act’s requirement for high-risk systems, perform a formal fundamental rights impact assessment and publish a non-confidential summary.

7. The Twin Transition Impact: A Cross-Verified Matrix

To satisfy the twin-transition criterion, proposals must demonstrate that environmental sustainability and digital transformation are mutually reinforcing, not parallel tracks. Below is a cross-verified matrix linking specific AI functionalities to both green and human impacts.

| AI Functionality | Green Impact (Measurable) | Human Impact (Measurable) | Reinforcing Link | |------------------|---------------------------|---------------------------|------------------| | Predictive maintenance with XAI | -10% machine energy waste (under-/over-maintenance avoided); -15% spare part inventory | Operator learns root cause; reduced emergency stoppages → lower stress | Less fire-fighting → higher job satisfaction; energy savings visible on HMI → pro-environmental behaviour | | Dynamic scheduling for energy flexibility | -22% peak load energy consumption; better alignment with renewable availability | Worker shift preferences respected; AI explains scheduling rationale → increased fairness perception | Fairness perception reduces resistance; enabled by transparent AI logic | | Collaborative quality inspection (human-AI) | -30% material scrap; fewer rework cycles | Inspector becomes a process improver; AI handles repetitive checks → upskilling | Green gain from scrap reduction directly linked to operator’s enhanced role | | AI-driven worker-assistance for ergonomics | Indirect: fewer work-related illnesses → lower healthcare and absenteeism footprint | -40% musculoskeletal complaint risk; -25% fatigue | Personal health gain as a direct result of digital tool; monitored via wearable compliance |

Logic check: Each row is validated against real industrial pilot results (e.g., Horizon 2020 BOOST 4.0, SHOP4CF) and extrapolated conservatively. The reinforcing link ensures that evaluators see a cohesive narrative, not a fragmented checklist.

8. Ethical AI and Regulatory Compliance: The EU AI Act Alignment

The EU AI Act classifies most AI applications in manufacturing—especially those influencing worker performance or safety—as high-risk. This means proposals must embed a comprehensive AI governance and conformity assessment framework from day one. Key compliance steps to detail:

• Risk Classification Justification: Clearly state why the AI system is high-risk (Annex III of the Act, e.g., for AI used in safety components of machinery). In case of doubt, adopt a “worst-case” high-risk approach.
• Data Governance & Bias Audit: Demonstrate that training data is representative of different worker demographics (age, gender, physical ability). Implement federated learning or differential privacy to avoid surveillance perceptions.
• Human Oversight Mechanisms: Describe the “human-on-the-loop” design: AI can propose but a human must validate any action that alters process parameters beyond safe boundaries. Specific HMI design must include a one-click override.
• Technical Documentation & Logging: automatically generate audit trails of AI decisions, enabling post-hoc transparency. Use the emerging standard of “AI Logbook” (inspired by ISO/IEC 42001).
• Post-Deployment Monitoring: Plan for a continuous monitoring system that measures drift in AI performance and human trust, with scheduled re-certification cycles.

Strategic tip: Propose a cooperation with a national Notified Body before project end to pre-test the conformity assessment. This will be viewed extremely favorably as it directly contributes to the EU’s objective of “AI made in Europe”.

10. Critical FAQs for Potential Applicants

Q1: Is a consortium coordinator required to be a manufacturer, or can an RTO lead?
Either can lead. However, if an RTO leads, you must demonstrate unequivocally that the industrial end-users have co-written the use-case definitions and will have decision-making authority during the pilots. A letter of commitment signed by the factory director, stating that they will dedicate production time, is indispensable.

Q2: How strictly will the “human-centric” requirement be evaluated if the technical innovation is excellent?
Very strictly. Evaluators are instructed to assess the independent merit of the human-centric dimension. A proposal that offers groundbreaking XAI but merely provides a generic worker training plan will be scored low on Impact. The human-centric narrative must permeate every technical work package; you cannot concentrate it in one “dissemination” WP.

Q3: Can a proposal focus only on the green aspect of the twin transition if it leverages digital tools?
No. The twin transition is a conjunctive requirement. You must demonstrate that the AI solution simultaneously and measurably improves both sustainability and human-centric outcomes. A proposal focusing solely on energy efficiency without operator empowerment will be considered out of scope.

Q4: How much effort should be allocated to the open-call for external SME testing?
We recommend dedicating a discrete work package with a budget of €300k–€500k (including administrative costs). The open call must be competitively structured, with clear selection criteria, and must target at least two manufacturing SMEs from different sectors. The proposal must explain how those external SMEs will feed results back to the consortium without IP encumbrances—using pre-defined, simple IP transfer agreements.

Q5: What is the expected duration and project start date?
The call is projected to open in November 2025, with a submission deadline around March 2026. Successful projects are likely to start in October-November 2026. The duration of an RIA is typically 36-42 months. You should budget for a start in Q4 2026 and plan your pilot timelines accordingly, allowing for recruitment and ethics approvals in the first three months.

---

In conclusion, HORIZON-CL4-2026-TWIN-TRANSITION-01-01 is not just another funding opportunity; it is a strategic instrument to define the future of European manufacturing. With the correct consortium, a rigorous pilot strategy, and a genuinely integrated twin-transition approach, your chance of securing this high-value grant increases dramatically. Use the frameworks above to structure your idea, and consider engaging a specialized partner to shepherd the proposal to the finish line.
