Driving Global Innovation in Hydrogen-Combustion Flight
Phase 1: hydrogen-combustion turbofans using compressed gaseous H₂ — no cryogenics. Phase 2: passenger aircraft built around them. Safety and certification from day one in Guanacaste, Costa Rica (LIR).
Open Round
Hydrogen-Combustion Turbofans
We’re raising to achieve pressurized single-sector hot-fire and publish our NOx/stability maps. Engines first. Aircraft next.
Problem → Opportunity
Aviation must decarbonize, but batteries can’t deliver payload-range for turbofan missions today. Hydrogen combustion works at engine scale—the gap is ultra-low NOx, flashback-safe mixing, and certifiable high-pressure storage.
ColibriV focuses here: converting proven physics into certifiable, near-term products operators can adopt.
Phase 1 — Engines
- • Lean-premix / micromix combustor
- • Type-IV gaseous H₂ (350–700 bar)
- • AI-assisted test analytics
Phase 2 — Aircraft
- • Scalable passenger aircraft family (short-haul to trans-national)
- • Smart tank placement & CG management
- • Rapid refuel and real-world operations across diverse airports

For Investors
Hydrogen CombustionEngines FirstScalable Aircraft FamilyMulti-Country Ops
We are developing hydrogen-combustion turbofans using compressed gaseous H₂ (no cryogenics) and building toward a scalable passenger aircraft family for multi-country operations. Near-term value lies in emissions control, flashback safety, and certifiable high-pressure storage—engine-level data and IP that enable licensing and retrofit while we progress aircraft sizes and international certification pathways.
Pre-Seed (Now)
US$1.5–3.0M
Deliver pressurized single-sector hot-fire, initial NOx/stability maps, and a complete safety/cert plan (ARP/DO) to unlock the core-engine run.
- • Supplier MoUs (tanks, valves, gas partner)
- • HAZOP/FMEA v1, PRD & ventilation strategy
- • Data Pack v1 (plots + test logs) under NDA
Seed (Next)
US$10–12M
Execute the core-engine hydrogen ground run, kick off the flight testbed, and launch the global certification workstream (EASA/FAA and partner authorities) to support multi-country operations.
- • Core hardware + emissions campaign
- • Testbed approvals with DOA/ODA partner
- • International cert path mapping (EASA/FAA/DGAC-CR + partners)
- • Long-lead orders & aircraft trade studies
Monetization Path
IP licensing (combustor, mixing, controls), retrofit/integration kits for existing platforms, and a scalable aircraft program (multiple sizes) with after-market services for multi-country operators.

Near-Term Milestones
- Single-sector hot-fire at pressure; initial NOx & stability maps
- Means-of-Compliance draft & safety artifacts (ARP/DO)
- Core-engine test plan with DOA/ODA; supplier MoUs finalized
- Multi-authority certification mapping (EASA/FAA/DGAC-CR)
What differentiates you from incumbents?
We execute at engine level now—owning mixing, staging, controls, and validated emissions data. That creates licensing/retrofit revenue while we mature an aircraft family. Incumbents move on long timelines; our edge is speed-to-evidence with certification front-loaded.
Why gaseous hydrogen (non-cryogenic)?
Faster test cadence and fewer operational complexities for near-term demos. It’s ideal for proving combustion, safety, and emissions while building partner and market traction across multiple countries.
How do you manage safety & certification risk?
Alignment with ARP4754A/ARP4761, DO-160, and DO-178C; HAZOP/FMEA with defined PRD and ventilation strategies; and early DOA/ODA engagement to lock means-of-compliance for multi-authority pathways.
