HyLight launched on Y Combinator's "Launch YC" recently!
"Small unmanned hydrogen airships for long range monitoring"
HyLight builds and operates hydrogen airships for energy infrastructure monitoring. They're currently running a paid pilot with the largest power line company in Europe and help companies inspect their assets in a sustainable & cost-effective way.
HyLight builds small unmanned hydrogen airships to automatically gather massive amounts of precise data in a sustainable and cost-effective way. 🚫 The problem
Current solutions (helicopters, airplanes, satellites and drones) are not adapted to make accurate, efficient and sustainable observations.
HyLight is currently focused on:
💨 Pipeline inspection to detect methane leaks (4% of global greenhouse gas emissions).
⚡Power line inspection to prevent outages, reduce wildfire risks ($19 billion per year in the US), and ensure grid reliability.
✅ HyLight's solution
HyLight's solution is a crossover between drone and lighter than air technologies, using hydrogen as a lifting gas and power source.
