Underwater Data Center Market Size And Revenue Outlook Through 2030
The underwater data center market has seen swift expansion in recent years. Its value is set to climb from $1.11 billion in 2025 to $1.33 billion in 2026, exhibiting a compound annual growth rate (CAGR) of 19.9%. Historically, this market’s development can be linked to factors such as the increasing demand for sustainable data center solutions, rising energy costs, the adoption of cloud computing infrastructure, growing data storage requirements, and the expansion of telecommunications networks.
The size of the underwater data center market is projected to experience rapid expansion over the coming years. This market is forecast to reach $2.78 billion by 2030, exhibiting a compound annual growth rate (CAGR) of 20.2%. Factors driving this growth during the projection period include the increasing global deployment of underwater data centers, the escalating adoption of liquid immersion cooling to enhance efficiency, the rising need for edge computing in coastal regions, the expansion of AI and ML processing capabilities beneath the surface, and a heightened emphasis on decreasing the carbon footprint associated with data infrastructure. Key trends anticipated during the forecast period encompass the greater embrace of water and liquid immersion cooling methods, an uptick in the deployment of both shallow and deep-water data centers, the increasing incorporation of energy management and infrastructure monitoring software, the broadening of edge computing and AI/ML processing applications, and an elevated focus on remote operations and managed services.

Underwater Data Center Market Demand Drivers: What’s Powering Industry Growth?
The increasing volume of data traffic is projected to fuel the expansion of the underwater data center market in the future. Data traffic represents the quantity of digital information conveyed over networks and the internet during a specific timeframe, encompassing activities like streaming, cloud computing, file sharing, and real-time communications. This rise in data traffic, driven by the rapid increase in internet-connected devices and the widespread use of data-heavy applications such as video streaming, artificial intelligence, and cloud services, is exerting immense pressure on current land-based infrastructure. The escalating global transmission and processing of data heighten the demand for extensive, energy-efficient data center capabilities, positioning underwater facilities as an increasingly attractive option because of their inherent cooling benefits and closeness to coastal urban areas. As an illustration, a report issued in June 2024 by Ericsson, a Sweden-based telecommunications company, revealed that mobile network data traffic grew quarter-on-quarter by roughly 6 percent from the fourth quarter of 2023 to the first quarter of 2024. During that period, the cumulative worldwide mobile network data traffic for a specific month amounted to 145 exabytes (EB). Consequently, the escalation in data traffic is propelling the expansion of the underwater data center market.

Underwater Data Center Market Innovation Trends: What Developments Are Reshaping The Industry?
Major companies within the underwater data center market are concentrating on developing advanced solutions, such as seawater-cooled subsea modules, to boost energy efficiency, improve thermal management, and facilitate high-density computing beneath the ocean’s surface. Seawater-cooled subsea modules are pressure-resistant, sealed data center units installed underwater that employ the surrounding seawater as a natural heat sink, integrating sophisticated heat exchangers and renewable energy connectivity to maintain optimal server temperatures and lessen reliance on conventional air-conditioning systems. For instance, in October 2025, HiCloud Technology Co., Ltd., a China-based technology company, introduced a wind-powered underwater data center, which is a seawater-cooled subsea module. This solution, designed to assist hyperscale computing operators and cloud service providers, merges offshore wind energy with natural seawater cooling, includes sealed steel enclosures suitable for deep-sea deployment, and achieves a targeted power usage effectiveness (PUE) below 1.15 via optimized thermal exchange systems, thus enabling a sustainable, high-performance, and environmentally friendly underwater computing infrastructure.
