Underwater Data Center Global Market Report 2026

An underwater data center is a specialized facility for data storage and processing installed beneath the ocean or other large water bodies to house computing infrastructure such as servers and networking equipment. It leverages the naturally cool underwater environment to efficiently dissipate heat, reducing the need for conventional cooling systems and lowering energy consumption. These facilities are designed to improve energy efficiency, enhance data processing performance, and support sustainable deployment of data infrastructure.

The main components of underwater data centers include hardware, software, and services. Hardware refers to the physical infrastructure and equipment used in submerged data center environments, including servers, storage devices, networking systems, and enclosure units that support underwater computing operations. These employ cooling techniques such as water cooling and liquid immersion cooling and are deployed in shallow water and deep water environments. They find applications in data storage, cloud computing, content delivery networks, artificial intelligence and machine learning processing, and edge computing, serving end users including telecommunications, cloud service providers, government and defense, research and academic institutions, and enterprises.

Tariffs on imported servers, cooling systems, networking equipment, and storage devices are impacting the underwater data center market by increasing capital expenditure and deployment costs, particularly affecting hardware and high-tech software components. Regions such as North America, Europe, and Asia-Pacific that rely on imported specialized hardware are most affected. While tariffs raise costs, they also encourage domestic manufacturing of servers and cooling solutions, drive innovation in energy-efficient and modular underwater data centers, and promote regional supply chain resilience.

The growth in the forecast period can be attributed to growing deployment of underwater data centers globally, rising adoption of liquid immersion cooling for efficiency, increasing demand for edge computing near coastal areas, expansion of ai and ml processing underwater, growing focus on reducing carbon footprint of data infrastructure. Major trends in the forecast period include increasing adoption of water and liquid immersion cooling techniques, rising deployment of shallow and deep water data centers, growing integration of energy management and infrastructure monitoring software, expansion of edge computing and ai/ml processing applications, rising focus on remote operations and managed services.

The surging data traffic is anticipated to propel the growth of the underwater data center market going forward. Data traffic refers to the volume of digital data transmitted across networks and the internet within a given period, encompassing activities such as streaming, cloud computing, file sharing, and real-time communications. The surging data traffic, driven by the rapid proliferation of connected devices and widespread adoption of data-intensive applications such as video streaming, artificial intelligence, and cloud services, is placing unprecedented strain on existing land-based infrastructure. The increasing volume of data being transmitted and processed globally intensifies the demand for large-scale, energy-efficient data center capacity, making underwater facilities an increasingly viable solution due to their natural cooling advantages and proximity to coastal population centers. For instance, in June 2024, according to a report by Ericsson, a Sweden-based telecommunications company, from Q4 2023 to Q1 2024, mobile network data traffic experienced quarter-on-quarter growth of approximately 6 percent. The total global mobile network data traffic for the month reached 145 exabytes (EB). Therefore, surging data traffic is propelling the growth of the underwater data center market.

Key companies operating in the underwater data center market are focusing on developing advanced solutions, such as seawater-cooled subsea modules, to enhance energy efficiency, improve thermal management, and support high-density computing beneath the ocean surface. Seawater-cooled subsea modules refer to pressure-resistant, sealed data center units deployed underwater that utilize surrounding seawater as a natural heat sink, integrating advanced heat exchangers and renewable energy connectivity to maintain optimal server temperatures while reducing dependence on traditional air-conditioning systems. For example, in October 2025, HiCloud Technology Co., Ltd., a China-based technology company, launched a wind-powered underwater data center, representing a seawater-cooled subsea module. Designed to support hyperscale computing operators and cloud service providers, the solution combines offshore wind energy with natural seawater cooling, incorporates sealed steel enclosures suitable for deep-sea deployment, and achieves a targeted power usage effectiveness (PUE) below 1.15 through optimized thermal exchange systems, thereby contributing to sustainable, high-performance, and environmentally efficient underwater computing infrastructure.

In May 2023, Atlas Technology, a Singapore-based Web3 infrastructure service provider, partnered with Shenzhen Hicloud Data Center Technology to accelerate the commercialization of sustainable underwater computing infrastructure. Through this partnership, Atlas Technology and Shenzhen Hicloud Data Center Technology aim to propel advancements in subsea data center deployment, contributing to and supporting the promotion of energy-efficient, renewable-powered digital infrastructure to meet next-generation offshore computing requirements.
