Fully submerged mission exceeded published performance specification in a non-linear underwater profile representative of real subsea operations

Burnaby, British Columbia – 21 April 2026 — Cellula Robotics Ltd has demonstrated more than 2,000 km of fully submerged endurance with its Envoy Autonomous Underwater Vehicle (AUV), powered by a hydrogen fuel cell, exceeding the platform’s published performance specification in a representative underwater mission profile.

Completed fully submerged, the mission provides a realistic indication of usable underwater range beyond a straight-line transit figure. Over the course of the profile, the Envoy AUV executed more than 4,000 turns and manoeuvres, each of which increased energy demand compared with steady, linear travel. This makes the result a more meaningful demonstration of real-world subsea performance in practical operating conditions.

The milestone was achieved using hydrogen fuel cell technology developed with Infinity Fuel Cell and Hydrogen, Inc., whose fuel cell solution supports Envoy’s long-endurance performance below the surface.

The Envoy AUV remained on mission for 385 hours and covered 2,023 km submerged on hydrogen fuel cell power The result demonstrates persistent, long-range AUV performance in a real underwater operating context and reinforces hydrogen fuel cells as a practical enabling technology for extended autonomous subsea operations.
