Hannover Messe 2026: New Infrastructure for Industry 5.0

03.05.2026

7 min read

The Hannover Messe 2026 (20–24 April) made one thing crystal clear: the term Industry 5.0 has moved from EU research-programme jargon into the operational reality of manufacturing companies. For DACH CIOs, that means a shift that goes beyond technology selection. Hardware, software and data infrastructure are becoming a continuum. The investment decisions behind them are leadership decisions, no longer mere IT questions.

Key Takeaways

Industry 5.0 is now an investment framework: Hannover Messe 2026 showcased a critical mass of vendors explicitly working within the Industry 5.0 framework. The EU funding programme behind it makes it the official investment roadmap for the coming years.
IT/OT convergence is a CIO-level topic: Operational technology (control, sensing, machine connectivity) and IT infrastructure are merging. CIOs who cede the OT domain to their COO colleagues risk losing influence over core investment decisions.
Data sovereignty as a differentiator: Gaia-X-based data infrastructure was no longer a niche topic at Hannover Messe 2026. European customers now ask suppliers for GDPR-compliant data processing across the entire value chain.
Investment priorities are shifting: Resilience trumps short-term efficiency. Redundancy, redundancy across sites and edge-computing scenarios for production disruptions now rank higher than pure throughput optimisation.

From Industry 4.0 to 5.0: What CIOs Need to Know About Operational Changes

What is Industry 5.0? Industry 5.0 is the EU’s research framework that goes beyond Industry 4.0 (efficiency through automation) by adding three dimensions: human-centricity (humans and machines as collaborative partners rather than humans replaced by machines), sustainability (circular economy as a production principle), and resilience (resistance to disruptions in supply chains and production). The European Commission explicitly funds Industry 5.0 research through Horizon Europe and the European Innovation Council.

For CIOs, the operational implications are more concrete than the concept suggests. Industry 4.0 was primarily an automation project with IT support. Industry 5.0 is an infrastructure initiative with strategic weight, because it answers the question: How will the factory of the next decade be connected, sovereign, and resilient?

Timeline: From 4.0 to 5.0 in DACH Practice

2018 to 2022

Industry 4.0: automation, ERP integration, early IoT deployments. IT and OT largely siloed.

2022 to 2024

Post-COVID resilience: supply-chain disruptions make redundancy a priority. First IT/OT convergence projects.

2024 to 2026

EU regulation (CSRD, NIS2, Ecodesign) meets Industry 5.0 funding programs. Data sovereignty becomes a requirement. Hannover Messe 2026 shows critical mass.

2026 to 2028

Industry 5.0 as investment framework: product passport, Gaia-X data spaces, human-robot collaboration as operational standards in lead markets.

IT/OT Convergence: Why It’s CIO Territory

Operational technology (OT) covers everything that controls machinery: SCADA systems, PLC controllers, process control technology. For years OT remained the domain of production engineers and COOs. IT departments rarely touched these systems.

That is changing structurally. Edge-computing infrastructure that processes machine streams in real time now sits at the intersection of IT and OT. If the CIO does not co-design the IT infrastructure in this context, decisions on data architecture, security concepts, and vendor dependencies are left to the COO or external system integrators. This is a power shift with long-term consequences.

CIO as IT/OT Shaper

Joint security concept for IT and OT
Edge-computing architecture on the shop floor
Data sovereignty over machine data
Vendor management for OT software
Coordination of product-passport data flows

Risks of a Passive CIO Role

Shadow OT architectures driven by COO solo decisions
NIS2 compliance gaps at IT/OT interfaces
Vendor lock-ins without IT governance
Data-silo structures blocking product-passport requirements
Lack of visibility into cyber-attacks on OT

Data Sovereignty: From Wish to Requirement

At Hannover Messe 2026, Gaia-X was omnipresent across the halls. Industrial data spaces for value chains (Catena-X for automotive, Manufacturing-X for industry) have now reached productive implementations. What does this mean for CIOs?

Major European customers are increasingly asking suppliers about their data-processing infrastructure. GDPR-compliant processing across the entire value chain is becoming a pre-qualification criterion in tenders. If you cannot answer “Where are your production data stored and which third parties have access?” you lose competitive position. This is no longer a compliance issue—it’s a sales question.

What CIOs Should Do Right Now

Three measures deliver a favorable cost-benefit ratio for entering Industry 5.0, regardless of company size or sector:

1. Coordinate an IT/OT inventory with the COO. Which OT systems are networked today? Where do the processed data end up and with which provider? This two- to four-week audit provides the foundation for NIS2 compliance and opens the dialogue with the COO on shared accountability.

2. Evaluate a data-space pilot. Catena-X onboarding is feasible for automotive suppliers with manageable effort. For non-automotive: Manufacturing-X has issued a call for pilot partners. A pilot with a strategic customer or supplier creates learning effects no concept can replace.

3. Anchor Industry 5.0 funding in the investment plan. The EU budget for Industry 5.0 projects under Horizon Europe 2024–2027 is limited. Submitting funding applications only in 2027 means competing for far fewer remaining funds. Assess now which ongoing or planned initiatives qualify for support.

Frequently Asked Questions

What exactly distinguishes Industry 5.0 from Industry 4.0 from a CIO perspective?

Industry 4.0 was primarily an efficiency project: automation, networking, and data collection to boost productivity. Industry 5.0 adds three dimensions that carry operational consequences for CIOs: human-centricity means designing human-machine interfaces as a core principle rather than replacing humans. Resilience means prioritizing redundancy as an investment. Sustainability means treating circular-economy data as an infrastructure requirement. The key difference in day-to-day leadership: Industry 5.0 decisions cannot be delegated to IT specialists because they directly impact business models.

How should CIOs position IT/OT convergence internally?

The most effective approach: frame IT/OT convergence not as IT expanding into OT territory, but as a joint infrastructure program with production and engineering colleagues. CIOs who make the shift from “IT service provider for the factory” to “joint infrastructure owner” consistently secure stronger budget positions, as shown in Hannover Messe documentation and DIHK surveys. This requires technical competence in OT basics (SCADA, PLCs, real-time demands) and political capital with the COO.

Which Gaia-X data spaces will matter to DACH industrial companies by 2026?

Catena-X (automotive supply chain) already has productive implementations with BMW, Volkswagen, and BASF. Manufacturing-X (cross-industry manufacturing) entered pilot phase in 2025/2026. For DACH CIOs outside automotive, starting via Catena-X-compatible interfaces makes sense because it offers the broadest vendor base. GAIA-X itself (gaia-x.eu) provides technical specifications and starter documentation for companies without automotive ties.

How are DACH CIOs prioritizing resilience vs. efficiency in their investment planning?

According to the DIHK Digital Report 2025, 58 percent of surveyed DACH industrial companies have elevated resilience investments (redundancy, multi-sourcing, edge failover) above pure efficiency in their priority lists. This is a direct response to supply-chain disruptions from 2021 to 2023. Practically, this means budget arguments for redundant infrastructure are easier to make in 2026 than in 2019, because the executive level has lived through the risks. This window is actionable.

What are the key takeaways from Hannover Messe 2026 for CIOs?

Three observations with direct relevance: first, IT/OT convergence is no longer a future topic—it has demonstrated mature implementations. Second, Gaia-X data spaces have moved beyond the concept phase. Third, vendors are explicitly positioning Industry 5.0 compliance as a differentiator against Asian competitors. For CIOs planning infrastructure investments in 2026/2027, Hannover Messe showed the market now delivers products, not just concepts.
