US-owned hydrogen-electric power systems for UAVs
Add endurance.
Not hydrogen complexity.
A qualified hydrogen-electric power and readiness system for persistent uncrewed aircraft. Endurance becomes a purchasable aircraft capability, not an internal hydrogen development program.
Target aircraft class: 15–35 kg MTOM, 0.8–1.2 kW cruise power.

Problem
Battery mass closes the mission before design review.
Endurance requirements convert directly into stored energy. At battery specific energy, that mass consumes the payload budget and the design loop ends before it starts.

Preliminary sizing range
Preliminary. Battery mass is the installed pack for 8.4 kWh delivered: 38 kg of cells at 220 Wh/kg cell-level, giving 45–48 kg at 176–187 Wh/kg pack-level after structure, BMS and wiring. Hydrogen hybrid sizing is preliminary and requires mission inputs: duty cycle, transient power, reserve policy, temperature and altitude.
Outcome 01
More payload, or more mission time.
Recovered mass is spent where the program needs it: sensors, comms relay, or additional hours on station.
Outcome 02
Refuel in minutes, not hours.
Cylinder exchange replaces charge cycles, so sortie rate is set by crew procedure rather than battery recovery time.
Solution
Three elements. One accountable supplier.
We deliver the airborne system, the ground support required to operate it, and an optional field hydrogen source when logistics demand it.
Airborne
Qualified endurance system
Fuel-cell module, hydrogen storage, hybrid battery, controller and installation kit, integrated and qualified as one aircraft power system.
Ground
Cylinder support package
Certified prefilled cylinder exchange, handling equipment, digital tracking and refuel procedures for sustained sortie rates.
Optional
Field hydrogen module
Partner electrolysis, purification and certified compression for sites where cylinder delivery logistics fail.
