Manufactured in the USA, our NDAA-compliant, fully electric UAVs boast industry-leading flight durations of up to 150 minutes, all while producing zero emissions and facilitating effortless refueling.H2-6 Unmanned Aerial System
Hydrogen-powered drone with extended flight capabilities and adaptable payload options

- Flight duration of up to 140 minutes with a 2 lbs payload
- Flight duration of up to 120 minutes with a 6 lbs payload
- Flight duration of up to 60 minutes with a 10 lbs payload
This fully electric platform is powered by easily replaceable hydrogen cylinders, utilizing an onboard fuel cell to convert hydrogen into electricity, emitting only water vapor as a by-product. With minimal moving parts, primarily the motors, the aircraft ensures enhanced reliability and reduced maintenance needs. The adaptable UAS can be tailored to meet specific mission demands and can accommodate a range of leading-edge payloads and sensors,including:- Sony ILX-LR1 – 61 MP camera for aerial inspections and photogrammetry
- Phase One P3 – 120 MP camera with integrated laser range finder,perfect for high-precision mapping and inspections
- AerialOGI – leading OGI (optical gas imaging) sensor for detecting methane and hydrocarbon leaks

Request Scenarios
Inspection of Power Lines, Pipelines & Railroads
The H2-6 can cover distances 3 to 5 times greater than battery-operated drones in a single flight, enhancing efficiency for long-distance inspections and corridor assessments, eliminating the need for frequent landings and battery changes.
Wind Turbine & Solar Farm Inspections
The H2-6 can survey multiple turbines and entire solar installations without needing to land,facilitating streamlined data collection and enabling operations during tighter weather conditions.
Optical Gas Imaging for Leak Detection
The H2-6 excels in optical gas imaging, providing extensive coverage for identifying methane and hydrocarbon leaks in oil and gas facilities, all while minimizing operational costs.
Photogrammetry & lidar Applications
With the H2-6’s extended flight capabilities, aerial photogrammetry operators can achieve high image resolution without sacrificing flight time. The platform can also carry heavy LiDAR payloads longer than battery-powered drones, resulting in greater coverage per mission and fewer data gaps.
Data Relay & Communication Support
The H2-6 can function as an airborne data relay,ensuring reliable connectivity that supports emergency responses and remote infrastructure operations in areas with limited communication or network access.
