U.S.-based C-Power is due to deploy its SeaRAY autonomous offshore power system (AOPS) at the U.S. Navy Wave

Energy Test Site in Hawaii this year, for example. SeaRAY incorporates a wave energy converter and communications gateway at the surface, with power stor- age and delivery and communications at the seabed. The power delivery will be via a Halo subsea battery storage sys- tem from UK ? rm Verlume (previously known as EC-OG). A trial is set to dem- onstrate the ability to support resident underwater vehicles with power for re- charging and communications.

Another wave energy technology com- pany, UK-based Mocean Energy, is also working with Verlume. It’s due to test its

Blue-X wave energy device with a Ver- lume battery offshore Orkney this year.

This is also to demonstrate operations with an AUV, as part of a project with oil major Harbor Energy, the Net Zero Tech- nology Center and subsea inspection ? rm

Modus.

US-based Ocean Power Technologies has been working in this space for a num- ber of years, working with Premier Oil (now part of Harbour Energy) in the UK and Eni in Italy to trial its wave energy device in support of powering subsea wells at end of ? eld life and supporting resident AUVs, respectively.

For those wanting somewhat more power, a more extreme example of po- tential power solution has been shared in

Russia. There, Project Iceberg, presented back in 2017, proposed equipping seabed production facilities, in ice-bound areas, with nuclear reactors to provide power.
