Ocean Power Technologies (OPT) and Stratum Holdings announced on Monday, October 26, 2026, that they have signed a non-binding letter of intent for a possible strategic collaboration: demonstrating offshore data center assets powered by renewable energy from waves, wind and sun.
Under the plan described in the announcement, OPT would grant Stratum a limited, non-exclusive licence to certain PowerBuoy platform patents for the demonstration programme, and would make available prototype assets it already has on hand. Stratum would contribute GPU assets, including latest-generation NVIDIA B300 GPUs, and integration expertise, and would pay OPT a monthly retainer under definitive agreements that still have to be negotiated.
What will be tested
The goal is to validate the technical feasibility of hosting edge AI inference and related workloads on systems powered mainly by onboard renewable generation, without a power cable connected to shore. According to the companies, local processing could also reduce the bandwidth needed to send data back to shore.
Another item to be tested is cooling: cooling accounts for a significant share of conventional data centers' power consumption, and the companies believe that placing these systems in cooler ocean regions could reduce that demand. The announcement itself makes clear that this has not yet been demonstrated and will be among the matters evaluated in the programme.
Patents and next steps
OPT says it holds more than 60 patents worldwide, including more than 15 in the United States, covering buoy architecture, energy conversion, mooring and anchoring systems, autonomous charging interfaces and communications. Initial efforts are expected to focus on system integration, performance validation and data collection from demonstration deployments.
“By combining our patented PowerBuoy technology with Stratum's GPU assets, we aim to demonstrate a practical path toward self-powered edge AI infrastructure that operates independently of shore-based power,” said Tracy Pagliara, Acting President and Chief Executive Officer of Ocean Power Technologies.
“Partnering with OPT allows us to explore the potential of renewable-powered offshore platforms combined with our GPU assets for edge AI inference, where local processing can reduce bandwidth requirements and leverage the natural cooling advantages of the marine environment,” said Nicholas H. Adler, Chief Executive Officer of Stratum Holdings.
What this is not yet
It is important not to overstate the announcement: there is no operating offshore data center and no definitive agreement has been signed. Results from the programme, if any, may inform future commercial applications in areas such as maritime domain awareness, offshore energy monitoring, scientific sensing and other remote edge-compute uses, but the announcement itself warns that the parties may never reach definitive agreements and that either side may end the talks.
