Having completed initial pressure testing of its underwater data center pods, US startup Subsea Cloud has confirmed its structural integrity and performance targets at depths of 3000 meters or 9481 feet. Maxie Reynolds, co-founder and CEO of Subsea Cloud, described this as an important milestone in the company's goal to deploy hundreds of subsea data centers.

The company is building an underwater data center pod (UDCP) incorporating two proprietary components. UDCP's fluid and custom-container design allows it to reach depths of 10,000 feet. Lights-out, it rests on the seafloor with no need for maintenance. The facility is also more physically secure than land-based data centers, while at the same time it reduces carbon emissions by eliminating electrically-driven cooling and water usage, and it cannot emit harmful gases into the atmosphere or water.

Subsea Cloud is undergoing a sustainability assessment with Gold Standard, a voluntary carbon offset program focused on progressing the United Nation's Sustainable Development Goals (SDGs). Furthermore, this will enable serial production of these data centers and deployment in areas where sustainability issues have prevented deployment.

Subsea cables connect the pods to the grid at their destination. Pods will be installed in a modular fashion. As compared to a comparable land-based center, the first ten pods to be deployed will offset more than 7683 tons of CO2, the company claims.
