H3 Dynamics is a leading global developer of hydrogen solutions purpose-built for commercial and defense UAV and drone applications. Our product portfolio includes the Aerocell—a lightweight hydrogen-electric propulsion system—and the H2-Field, a mobile hydrogen refueling trailer designed for rapid deployment in remote environments. Together, these technologies enable emissions-free, long-endurance flight and autonomous field operations, empowering mission-critical applications across some of the world’s most demanding industries.
Aerocell Fuel Cell System
Lightweight hydrogen fuel cell systems for drones
The H3 Dynamics Aerocell is an innovative, light weight, PEM, hydrogen fuel cell system engineered specifically for drones and UAVs (unmanned aerial vehicle). Designed to overcome the limitations of conventional battery power and combustion engines, the Aerocell significantly extends flight endurance while minimising noise and thermal signatures.
The Aerocell’s advanced hydrogen fuel cell systems are enabling the next generation
- 5x longer endurance missions, unlocking beyond visual line of sight (BVLOS)
- Low acoustic and thermal signature
- Emissions-free operations.
- Remote field operations where hydrogen is unavailable.
Tailored for Defense and Commercial applications:
- ISR & Tactical Reconnaissance
- Border Security & Coastal Monitoring
- Stealth missions
- Disaster Response and Humanitarian Operations
- Logistics

Hywings H-25 Cargo UAV with Hydrogen Propulsion Nacelles
Hydrogen powered long-range fixed-wing logistics drone
The Hywings H-25 is a long-range fixed-wing UAV platform designed for zero-emissions cargo delivery applications. Powered by our unique Aeropak hydrogen propulsion nacelles, the H-25 can carry up to 5kg of cargo as standard.
The Aeropak nacelles can also be stacked to form a redundant distributed propulsion system, and allow the Hywings cargo UAV platform to be scaled up for custom solutions that can carry up to 500 kg.
Aeropak nacelles are also used to power Element One, a long-range hydrogen-electric concept aircraft designed for future cargo delivery and passenger transit requirements.
Element One is a 2018 concept design by H3 Dynamics of a zero-emission, long-range hydrogen-electric aircraft powered by a unique and patent pending distributed hydrogen-electric propulsion configuration.
