specific energy of the fuel-cell system, and help it meet the particular requirements of subsea applications. If successful, this novel new fuel cell could enable month-long underwater AUV missions, eliminating the need for either manned submarines for certain tasks or costly, diesel-using surface launch and retrieval vessels. “A fuel-cell AUV is ideal for things like Arctic surveillance,” says Jackson. “With our autonomous suction anchor,” also under development for DND now, “it could just park on the seafloor in power-saving mode for extended periods and, if it hears something, wake up and send data back.” Jackson believes ISE was “ahead of the curve” with its first AUVs, “designing fabulous machines, but it took the subsea world some time to catch up.” Now that it finally has, “I think the market is going to be big, really big. It’s a big ocean and there’s a lot of oil and gas there, there’s wind power, there’s tidal and wave generation, fishing, aquaculture, mineral exploration—they’re making new discoveries all the time, finding a lot of heavy rare earth elements.” For British Columbia’s ISE and Cellula, in other words, the world just may be their oyster.
