Cellula Robotics
Cellula designs and builds its own AUV platforms end to end, pairing high-pressure hydrogen/oxygen fuel cells with Li-ion batteries for multi-month, multi-thousand-kilometre submerged missions. In April 2026 its Envoy AUV demonstrated more than 2,000 km of fully submerged endurance on hydrogen fuel-cell power. The Solus-XR (now Guardian) achieved Canadian Maritime Autonomous Surface Ship (MASS) compliance in November 2024, and the company partners with Integer Technologies (Nexus mission-control software) for adaptive multi-vehicle undersea autonomy. Customer mix is dual-use: defense programs (DRDC, US DIU) alongside offshore energy, mineral-exploration and science applications.
