Panthalassa

Energy · Portland, United States · Founded 2016 Unicorn

Panthalassa is a renewable energy and ocean technology company founded in 2016 by Garth Sheldon-Coulson and Brian Moffat. The company is developing autonomous, floating nodes designed to harness the energy from open-ocean waves to generate electricity. The technology consists of a simple, solid-state spherical structure, approximately 50 meters in diameter, with a neck extending 60-70 meters below the surface. As wave motion moves the node, water is pumped into a pressurized reservoir and then flows through a single turbine to generate continuous power. This design aims to achieve a high capacity factor, delivering power up to 90% of the time, and intends to keep the energy generated in the ocean to power onboard applications. Potential uses include running AI computing clusters and producing clean fuels like green hydrogen directly at sea. The founders' backgrounds informed the company's direction; Garth Sheldon-Coulson was previously a senior investment associate and AI researcher, while Brian Moffat has a decade of research experience in ocean energy. Panthalassa's team includes professionals from aerospace companies, research universities, and naval architecture firms. The company has raised $78.1M in funding from investors including Founders Fund, Gigascale Capital, and Lowercarbon Capital to support its development and deployment efforts.
