In the quest for sustainable aviation, batteries alone cannot yet deliver on the payload-and-range demands of turbofan aircraft. That’s where ColibriV steps in — a bold startup addressing this gap with hydrogen-combustion turbofans.
Headquartered in Liberia, Guanacaste, Costa Rica, and operating its engineering and partnerships from Denver, USA, ColibriV is driving global innovation in hydrogen-combustion flight.
Company Vision & Focus
ColibriV’s tagline — “Vision, Velocity, Vector, Vanguard, Vigilance for Sustainable Aviation” — makes its ambition clear: to lead the transition to zero-emission flight.
The company’s approach is “engines first, aircraft next.” Rather than building a complete aircraft from day one, ColibriV focuses on developing certifiable hydrogen-combustion turbofans (Phase 1) and then scaling into a passenger aircraft family (Phase 2).
Why Hydrogen-Combustion?
While electric and battery-powered aircraft attract much attention, for many missions — especially medium to long haul — batteries still fall short in energy density and weight.
ColibriV argues that hydrogen combustion can operate at engine scale without cryogenics (using compressed gaseous hydrogen), achieving performance compatible with existing turbofan missions.
Key technological challenges include ultra-low NOx emissions, flashback-safe fuel/air mixing, and high-pressure hydrogen storage.
Location Advantage – Liberia, Costa Rica
ColibriV has chosen Liberia (Guanacaste) as its test and operations site, citing “cooperative authorities, a stable climate, and access to hydrogen infrastructure” that allow faster design-to-data cycles and earlier risk reduction.
This strategic location supports rapid turnaround testing and hands-on operational learning in a favourable environment.
Roadmap & Milestones
- M0: Architecture down-select, supplier MOUs, safety plan
- M1: Single-sector cold-flow and ignition, flashback margin testing
- M2: Pressurised single-sector hot-fire, NOx and stability mapping
- M3: Core-engine hydrogen ground run plan and flight testbed
Business & Monetisation Model
ColibriV intends to generate revenue through:
- Licensing IP for combustors, mixing systems, and controls
- Retrofit/integration kits for existing platforms
- Developing a scalable passenger aircraft programme (including after-market services and multi-country operations)
Certification & Safety Focus
From the outset, ColibriV emphasises certification pathways and regulatory alignment.
Its avionics and engine development work complies with standards such as ARP 4754A, ARP 4761, DO-160, and DO-178C, while incorporating HAZOP/FMEA and early means-of-compliance planning.
This commitment to safety and certification is essential for gaining acceptance in such a highly regulated industry.
Conclusion
As the aviation industry races toward decarbonisation, companies like ColibriV are poised to bridge the gap between concept and certified reality.
By focusing on engine-level innovation first and leveraging its strategic location in Costa Rica for testing, the company aims to deliver tangible, near-term progress in hydrogen-combustion flight.
ColibriV’s journey is one to watch — for investors, regulators, airports, and aviation operators alike.
