Energy density of lithium batteries hit the fundamental limit, which no one can break through for a decade. Our solution is lightweight Plug&Play hydrogen stack. Its x5 times better than Li-ion and based on 7 years of research. Our product is changing the structure of markets and opening new possibilities for moving machines. For example, drones with our stack fly more than 3 hours instead of 20 minutes with Li-batteries; different shared mobility platforms drive of up to 700km instead of 150 km with Li-batteries; Backup systems for the 5G network are cheaper, lightweight and quiet.
