What GreenGT does
GreenGT SA is a Swiss hydrogen technology development partner specializing in fuel cell systems and integration services for original equipment manufacturers (OEMs) in aviation, defense, motorsport, and heavy-duty mobility. Founded in 2008 by Jean-François Weber and headquartered in Morges, Switzerland, the company supports customers across the full hydrogen value chain — from initial concept through production — with a portfolio of consulting, engineering, fuel cell systems (including its proprietary NGT cell), and technology integration services. Notable engagements include fuel cell supply for the 49 SUD ClimateImpulse hydrogen-powered aircraft, a strategic co-development partnership with Pratt Miller for defense and motorsport applications, and a hydrogen retrofit initiative for airport ground power units.
The company's core technology stack centers on fuel cell development and system integration, with proprietary expertise in hydrogen retrofitting of heavy-duty vehicles through its H2TICE platform and broader sector-coupling applications. GreenGT operates a direct enterprise field-sales model, selling bespoke engineering projects and fuel cell systems to OEM partners through project-based, non-publicly-disclosed pricing. With 11-50 employees, the company is small and founder-led, operating from a single Swiss site while serving a global customer base through a distributed partnership ecosystem that includes Airbus, Liebherr, EKPO Fuel Cell Technologies, Hitachi, RUAG, Syensqo, and other major industrial players. The company holds ISO 9001 certification validated by SGS.
GreenGT generates revenue through a mix of one-time system deliveries (e.g., fuel cell supply for ClimateImpulse), professional services contracts (consulting and engineering), and technology integration engagements (H2 retrofit solutions for trucks and airport GPUs). Recent commercial momentum is evidenced by the 2025 Pratt Miller partnership, the 2024 49 SUD contract, and the 2025 launch of an airport GPU hydrogen retrofit project, alongside international trade show appearances at CES 2025 and AERO Friedrichshafen 2026. However, GreenGT remains at an early commercial stage: its only recorded capital event is a CHF 290,000 grant from the Canton of Fribourg in January 2026 for the H2TICE project, and the company has not raised institutional equity funding or disclosed revenue figures.

GreenGT competitors and assessment
Company assessmentEmerging players
- ZeroAvia: Hydrogen-electric aviation propulsion developer; comparable to GreenGT's ClimateImpulse/aviation fuel cell integration work and addresses the same emerging H2 aviation market.
- Cellcentric: Volvo Group/Daimler Truck JV developing heavy-duty fuel cell systems; competes directly for the same heavy-duty mobility contracts GreenGT targets.
- Universal Hydrogen: Hydrogen powertrain and infrastructure company focused on aviation; comparable to GreenGT's hydrogen aviation integration thesis.
Broad incumbents
- Ballard Power Systems: Mature PEM fuel cell manufacturer targeting heavy-duty mobility, marine and stationary power; broader and more capital-intensive than GreenGT but competes for the same OEM programs.
- Cummins Accelera: Cummins' hydrogen powertrain unit covering fuel cell and hydrogen production for heavy-duty trucks, rail and industrial applications — broader incumbent competing in GreenGT's heavy-duty niche.
- Plug Power: Larger hydrogen fuel cell and infrastructure player targeting mobility and stationary applications; overlaps conceptually with GreenGT but at very different scale.
Direct peers
- Hyliko: French hydrogen heavy-duty truck developer covering retrofit and fleet solutions — directly overlaps with GreenGT's H2TICE heavy-duty truck retrofit focus.
- Refire: Hydrogen fuel cell system integrator for commercial vehicles and power applications; a partner of GreenGT and a peer in hydrogen system integration.
