Our goal is to create an advanced ecosystem featuring a fully integrated hydrogen infrastructure, enhancing the drone sector with unprecedented levels of cost efficiency, operational endurance, and scalability.
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
The H2-6 represents a groundbreaking hydrogen-powered multirotor UAS, delivering top-tier flight durations for unmatched operational efficiency. Crafted in the USA, it adheres to all NDAA and FAA standards, including Remote ID, and is equipped for BVLOS (beyond visual line of sight) missions.
- 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.
