Overview
HyLight designs, manufactures and operates long-endurance autonomous airships that carry cameras, LiDAR and methane sensors over linear infrastructure. Its software converts the collected data into geolocated inspection findings for network operators.
Why HyLight is interesting
HyLight targets a costly inspection market where helicopters offer range but high emissions and operational risk, while conventional drones, satellites and ground sensors each leave coverage gaps. Commercial deployments with major infrastructure operators make fleet industrialisation the central execution test.
Product & use cases
The 12-metre HyLighter uses helium for lift and a hydrogen fuel cell to power electric motors. It can carry up to 10 kilograms of sensors and has regulatory approval for beyond-visual-line-of-sight operations over critical infrastructure.
- Power-line inspection
- Pipeline and methane-leak monitoring
- Railway inspection
- Critical-infrastructure digital mapping
Key facts
- More than 750 flight hours and thousands of kilometres inspected, according to the company.
- Customers named by the company include Enedis, NaTran, Téréga, SNCF Réseau and VINCI.
- Targeting a fleet of 15 HyLighters by 2027 from four aircraft.

Competitive landscape
Edge: Long endurance and low-speed flight can combine the coverage of helicopters with denser data collection and zero in-flight emissions.
HyLight competes most directly with helicopter inspection providers, while long-range drones, satellites and fixed ground sensors are alternative data-collection methods. Its advantage depends on reliable operations, regulatory approvals and fleet utilisation.
-
Helicopter inspection operators incumbent
Provide proven long-range inspection but at higher cost, emissions and operational risk.
-
Long-range UAV providers direct
Offer unmanned inspection with lower emissions but generally less endurance or payload.
-
Satellite imagery providers alternative
Cover large areas but with lower spatial precision and revisit constraints.
