Cellen, Cantronic Team on Aerial Methane Detection
The partnership pairs a hydrogen-powered drone with an optical gas imaging payload to locate methane leaks over longer flight times.
Updated on Nov. 2, 2026 in Oil and Gas
Cellen H2 and Cantronic Systems Inc. announced a partnership to integrate Cantronic's REDEAGLE U340 optical gas imaging payload with Cellen's H2-6 hydrogen fuel cell drone. The companies are developing a long-endurance aerial methane detection solution.
Why it matters
Methane leak detection is a growing focus for oil and gas operators in Houston and across Texas, where regulators have issued optical gas imaging leak detection implementation guidance in 2026. A drone platform that stays aloft longer could help operators survey more infrastructure per flight.
The H2-6 platform is rated for about 90 minutes of flight, roughly three times a comparable battery-powered drone. Performance in real operating conditions has not been reported, and the U340 payload remains in ground testing in Erie, Colorado.
The players
Cellen H2
Cellen H2 is a company that builds hydrogen fuel cell drone platforms, including the H2-6 used for long-endurance flight.
Cantronic Systems Inc.
Cantronic Systems Inc. is a gas detection company that makes the REDEAGLE U340 optical gas imaging payload.
Texas Commission on Environmental Quality
The Texas Commission on Environmental Quality is the state agency that regulates air emissions and issued optical gas imaging leak detection guidance in 2026.
The details
The U340 optical gas imaging payload pinpoints where a leak is located and is paired with third-party quantification software to support leak rate estimation. The H2-6 runs on a hydrogen quick-change cylinder, which the companies position as a way to extend flight time.

Market Landscape
The partnership adds an aerial platform to optical gas imaging methods that Texas regulators have addressed in 2026 implementation guidance. It positions the companies among a growing set of technology providers competing to serve oil and gas operators facing tighter methane monitoring requirements.
Operators inspecting pipelines and well sites may eventually see aerial OGI surveys added to their leak detection programs, which could change inspection schedules. The effect on operating costs has not been reported.
The takeaway
Aerial leak detection is moving toward longer flights and specialized payloads, so operators tracking methane compliance should watch how field results compare with the claimed endurance figures.
