Europe’s power grids, pipelines and rail networks mostly get inspected by helicopter, which is expensive, weather-dependent and risky. A French startup wants to replace that with something slower and cheaper.
HyLight, founded in 2022, builds autonomous hydrogen-powered airships for aerial infrastructure inspection. The company has raised €13M from Rubio Impact Ventures, DRW and Teampact Ventures, with existing investors Y Combinator and Ring Capital following on.
The premise is endurance. Airships stay aloft far longer than quadcopters and carry heavier sensor payloads than fixed-wing drones, which suits the long linear corridors of transmission lines and pipelines.
HyLight has already cleared a hurdle that stops most industrial hardware startups: it designed, built and industrialised its aircraft rather than stopping at a prototype.
Grid operators across Europe are under pressure to inspect ageing infrastructure more frequently as renewables add strain and extreme weather accelerates wear. Manned inspection flights are one of the largest line items in that maintenance budget.
Hydrogen as the lift and power source cuts emissions against helicopter alternatives, and the slow flight profile produces clearer imagery than fast-moving aircraft.
