Portland Startup Gets $140M for Wave-Powered Data Centers

Imagine data centers that float in the ocean, powered entirely by waves and cooled by seawater instead of guzzling electricity and fresh water on land.

That future just got $140 million closer to reality. Portland startup Panthalassa raised the massive funding round to build floating computing stations that turn wave energy into clean power for artificial intelligence.

The technology is surprisingly elegant. Steel spheres about 33 feet wide bob vertically in the ocean, with 200-foot columns extending underwater. As waves move the spheres up and down, they force pressurized seawater through turbines that generate electricity. That power runs computer servers onboard, which communicate with land via satellite.

The spheres don't anchor to the ocean floor. They're self-propelled and use the surrounding seawater to cool the hardware naturally.

Billionaire investor Peter Thiel led the funding round, joined by venture capitalist John Doerr, Salesforce CEO Marc Benioff's TIME Ventures, and PayPal co-founder Max Levchin's SciFi Ventures. The investment values Panthalassa at $1 billion and will fund prototype development and a pilot manufacturing facility in Vancouver, Washington.

Founded in 2016, the company now employs 120 people. CEO Garth Sheldon-Coulson says the Pacific Northwest's maritime infrastructure and tech talent make it the perfect hub for ocean energy innovation.

The timing couldn't be better. Data centers supporting AI have exploded across Oregon, with communities making room for 9,100 acres of new facilities that could quadruple the industry's footprint. These centers consume enormous amounts of electricity and water for cooling, straining local resources and prompting Governor Tina Kotek to form a task force studying their environmental impact.

The Ripple Effect

Panthalassa's approach tackles both problems at once. The ocean contains tens of terawatts of untapped wave energy, and floating data centers eliminate the need for freshwater cooling systems that stress municipal supplies.

The company plans to deploy fleets of these floating nodes in the planet's most energy-dense wave regions, far from shore. Each sphere represents a small piece of infrastructure that collectively could add up to significant clean computing capacity.

For Oregon communities watching data center development reshape their landscapes, this offshore solution offers a glimpse of how technology's growing energy appetite might be satisfied without overtaxing local power grids and water systems.

Clean energy from the ocean could power the digital future while leaving coastal communities with resources to spare.
