OPT Expands Power Options
Ocean energy solutions developer Ocean Power Technolo- gies, Inc. has expanded its suite of complimentary products that leverage the core technology of the PowerBuoy, which include subsea batteries and a hybrid (liquid-fueled) Power-
George H. Kirby, President and Chief Executive Of? cer of
OPT, said, “Our team has been working diligently to iden- tify opportunities to leverage our technologies to address the needs of current and potential customers in subsea environ- ments. These new product offerings provide OPT with the means to better serve customers by expanding its product and service offerings. In addition, this allows us the opportunity to have broader discussions during each customer visit, pro- viding more comprehensive solutions and further establishing our credibility and our ability to address each unique market.
“Our new products, subsea batteries and the hybrid Power-
Buoy, along with our existing PB3 Power-Buoy and backed by our existing support services, provide more comprehensive solutions that can meet the needs of more customers requir- ing reliable power and communications in their subsea work across the globe.”
OPT’s entry into the subsea battery market presents a com- plementary product to the PB3. Subsea batteries create a sea

These subsea batteries use lithium ion batteries (often replac- sea? oor battery. ing traditional lead acid batteries) to supply power that can
