OceanBit, a developer of Ocean Thermal Energy Conversion (OTEC) technology, and Energy Estate, an energy and infrastructure development company, have partnered to build ocean thermal power plants paired with data centers. The initiative aims to enhance energy and digital resiliency for coastal and island communities in the Pacific and Indian Oceans.
According to a press release, OceanBit states that the partnership intends to replace diesel generators with sustainable, carbon-free energy while supporting high-density compute infrastructure. It also aligns with Energy Estate Digital’s expansion of subsea data cables connecting major digital hubs, including California, Japan, India, and Australia/New Zealand, with landing points on islands such as Hawaii, Fiji, the Maldives, and Coco Islands.
Vincent Dwyer, Co-Founder, Energy Estate, said, “By combining OceanBit’s technology leadership with our track record of developing energy and digital infrastructure, we can create resilient, future-ready ecosystems that deliver real and enduring benefits for coastal communities and industry.”
Nathaniel Harmon,Co-Founder & CEO, OceanBit, said, “Our collaboration with Energy Estate accelerates our mission to deliver sustainable energy to global communities and we will set new benchmarks for energy efficiency, connectivity and environmental stewardship, safeguarding ecosystems and resources for current and future generations.”
Simon Currie, Co-Founder and Chief Projects Officer, Energy Estate, said, “Co-location is the future. Integrating data centers with Ocean Thermal power plants will help islands reduce dependency on fossil fuel imports and support existing and new industries through access to enhanced digital infrastructure.”
The integration of OTEC technology is intended to provide continuous renewable power to co-located data centers, helping reduce emissions, lower costs, and enable electrification of island and coastal communities. The partnership marks a strategic step toward combining renewable energy generation with digital infrastructure to strengthen resilience and sustainability in remote island regions.
