I-Démo — France’s Flagship Innovation Demonstration Competition — sits at the summit of France 2030’s competitive grant architecture. Managed by Bpifrance, it funds the most ambitious collaborative R&D projects in the country: large-scale demonstrators that prove breakthrough technologies work at industrial scale, not just in a laboratory. For companies at the technology readiness valley — past fundamental research but short of investable product — I-Démo is the instrument that closes the gap.
What I-Démo Funds
I-Démo targets Innovation Demonstration projects: experiments at full industrial scale that prove a breakthrough technology is economically viable. The program explicitly excludes pure research (covered by ANR’s PEPR programs) and commercialization (covered by First Factory and Bpifrance equity). It occupies the critical middle ground where European competitiveness is typically lost to better-capitalized US and Chinese competitors.
Eligible project types:
- Industrial demonstrators proving new manufacturing processes at scale
- First-of-kind systems testing breakthrough technology under real operating conditions
- Collaborative platform projects uniting multiple companies and research institutions
- Green technology validation in the field (hydrogen production systems, battery chemistries, SAF production processes)
Funding Parameters
| Parameter | Detail |
|---|---|
| Minimum project cost | €5 million total eligible costs |
| Typical grant per project | €2M–€30M |
| Grant rate (companies) | 25–45% of eligible costs |
| Grant rate (research labs) | 40–65% of eligible costs |
| Project duration | 3–7 years |
| Minimum consortium | 1 company + 1 accredited research organization |
| Annual budget | Varies; typically €150M–€400M per major thematic call |
I-Démo grants are disbursed in tranches tied to project milestones — enforcing delivery accountability and aligning disbursement with actual progress.
I-Démo Across France 2030’s Ten Sectors
Every major I-Démo call since 2022 maps explicitly to France 2030 strategic sectors:
Hydrogen (€300M+ in I-Démo calls, 2022–2025): Electrolyzer scale-up demonstrators (10–100 MW), hydrogen mobility corridors, industrial process hydrogen injection for steel, cement, and glass.
Electric Vehicles and Batteries (€400M+): Next-generation battery chemistry demonstrators (solid-state, sodium-ion), battery recycling process validation, gigafactory automation pilots.
AI and Quantum (€200M+): Large-scale AI inference infrastructure, quantum error correction demonstrators, hybrid quantum-classical computing platforms.
Nuclear (€150M+): SMR component manufacturing demonstrators, advanced reactor materials testing, nuclear fuel cycle optimization.
Sustainable Aviation (€180M+): SAF production at scale, hydrogen aircraft propulsion ground tests, electric urban air mobility.
Semiconductors (€120M+): Advanced packaging technologies, silicon carbide wafer processes, photonic integrated circuit manufacturing.
Notable I-Démo Winners
Verkor (Electric Vehicles, 2022): French battery scale-up that won I-Démo funding for its battery chemistry demonstrator in Grenoble before scaling to its 16 GWh gigafactory in Dunkirk. The I-Démo grant — estimated at €12M–€18M — validated Verkor’s NMC cell technology before the company raised over €2 billion in total capital.
Lhyfe (Hydrogen, 2022–2023): Nantes-based green hydrogen producer secured I-Démo support for its offshore hydrogen production demonstrator — the world’s first system producing hydrogen directly from an offshore wind turbine at sea. Validated a model Lhyfe intends to deploy at gigawatt scale by 2030.
Alice & Bob (Quantum, 2023): Paris-based quantum computing startup received I-Démo funding to build a superconducting cat qubit demonstrator — hardware designed to reduce error correction overhead for fault-tolerant quantum computing.
Genvia (Hydrogen, 2023): The CEA/SLB joint venture secured I-Démo backing for its SOEC solid oxide electrolyzer demonstrator at Béziers. SOEC operates at 700–850°C using industrial waste heat, achieving 84–90% electrical efficiency. The grant supported a 1 MW pilot now scaled to 10 MW.
Newcleo (Nuclear, 2023): Lead-cooled fast reactor developer received I-Démo support for fuel fabrication demonstrator work — validating mixed oxide fuel rods for its LFR-AS-200 design.
The Application Process
I-Démo operates through thematic calls (appels à projets thématiques) rather than a permanent open window:
- Call publication: Bpifrance publishes call with full specification document
- Letter of Intent (optional): Submitted 8 weeks after publication; receives preliminary eligibility feedback
- Full Application: Submitted 16–20 weeks after publication. Required: technical description (50+ pages), consortium agreement, financial plan, environmental impact assessment, IP management plan
- Evaluation Phase: 16–24 weeks. Two-stage: technical expert panel then strategic panel
- Selection Committee: Bpifrance Investment Committee + SGPI representative
- Grant Agreement: Milestone-based disbursement negotiation (6–8 weeks)
Overall timeline from call to first disbursement: 12–18 months.
I-Démo: When to Choose It
I-Démo is the right choice when:
- Your project requires €5M+ total investment
- You have a credible industrial partner plus a research institution
- You are at TRL 4–6 (proof of concept to technology demonstrator)
- You can absorb a 12–18 month evaluation cycle
Choose I-Nov instead for projects below €5M total. Choose First Factory if technology is at TRL 7+ and ready for market.
The I-Démo Certification Effect
I-Démo winners close subsequent private financing rounds 40% faster and at higher valuations than comparable non-I-Démo companies in the same sector. This certification effect — government validation by independent technical experts — is arguably as valuable as the grant itself for early-stage deeptech companies.
