An autonomous underwater vehicle (AUV) developed by Canadian company Cellula Robotics has traveled more than 2,000 kilometers underwater, powered by a hydrogen fuel cell, exceeding published performance specifications.
During the mission, the Envoy AUV performed more than 4,000 turns and maneuvers, which used more energy compared to static linear travel, better demonstrating how the vehicle would perform in real-world underwater conditions, Cellula Robotics said.
According to the company, the hydrogen fuel cell system generates water as a byproduct.
“The significance of this result lies not only in the distance achieved, but in that it was achieved fully immersed in a mission profile that better reflects real subsea operations.” He said Neil ManningCEO of Cellula Robotics. “This is what makes endurance meaningful to operators, with the potential for reduced recoveries, more continuous operations, and greater offshore efficiency.”
Using hydrogen fuel cell technology developed in collaboration with Infinity Fuel Cell and Hydrogen, Inc., the vehicle remained on mission for 385 hours and traveled 2,023 kilometers underwater.
“We are proud to support a landmark that demonstrates what hydrogen fuel cells can enable in real subsea operations.” He said William SmithPresident and CEO of Infinity Fuel Cell and Hydrogen, Inc. “This result highlights the role that fuel cell technology can play in increasing endurance, reducing intervention requirements, and supporting more capable long-range autonomous missions.”
