Problem
Global energy demand is growing faster than terrestrial renewable infrastructure can be built, leading to supply constraints, high costs, and continued reliance on carbon‑intensive sources.
Solution
Panthalassa is developing a planetary‑scale energy platform that harvests power from the open ocean. By deploying modular, floating generation units in high‑resource marine environments, the system can be installed more quickly than land‑based projects and scaled to meet large‑volume demand. The platform is designed to deliver ultra‑low‑cost electricity with zero emissions, leveraging ocean wind, wave, and solar resources while minimizing land use and transmission losses. Energy produced offshore is transmitted to shore via high‑efficiency subsea cables, providing a continuous, renewable supply for compute clusters, data centers, and other high‑intensity loads.
Target Audience
Primary customers are large‑scale electricity consumers such as data center operators, cloud compute providers, and industrial facilities seeking reliable, low‑cost renewable power.
