About HyLight
Small unmanned hydrogen airships for long range monitoring
HyLight builds and operates autonomous airships for long range monitoring. We focus on detecting methane leaks on pipelines and defects on power lines. Our innovation, the HyLighter, is a crossover between drone and airship technology. Like a drone, it is easily controllable and transportable. And, like an airship, it is extremely energy-efficient, enabling it to fly for up to 10 hours at slow speed (22mph) for optimal data collection which represents a range of 220miles. Today, energy infrastructure operators struggle with conducting inspections that are simultaneously: massive and precise. HyLight offers a solution to precisely detect issues on the infrastructure at an industrial scale, and all of this without emitting GHGs. We are 3 co-founders experienced in hardware and energy companies with Masters in Mechanical Engineering, Computer Science and Business from the best Engineering and Business School in France. We have developed 5 different flying aircrafts and signed 5 pilots programs with major energy infrastructure operators. We also have LOIs worth over $3.5M.
