The Subsea Supercharger developed by Teledyne Energy Systems enables persistent AUV/ROV operations without needing a crew nearby to retrieve or redeploy the underwater vehicles, or a tether to supply power from above the water. In addition to the AUV/ROV operations, the Subsea Power System can be used to power subsea instruments that require a longer duration and power than batteries alone can provide. The system is fully recoverable and rechargeable.

The heart of the Subsea Supercharger is a fuel cell stack, a commercial product with over 10,000 hours of testing. The system can be customised to various power needs via additional fuel cell stacks and/or a hybridising battery and the power output can be changed as required. System life is guaranteed for 50,000 amp-hours with a fuel cell stack life expectancy of well over 100,000 amp-hours. The reactant tanks of hydrogen and oxygen can be stored indefinitely, no differently than if they were stored gas cylinders. A 5-year shelf life with no reduction in performance is typical.

For easy subsea connection the Subsea Supercharger uses Teledyne ODI DryMate / WetMate connectors. Teledyne Benthos acoustic modems are integrated into the system, which transmit up to 15.36 kbps of information over 9-27 kHz frequency bands to transducers 6km away.
