What Is The Driver Of The Underwater Data Center Market?

The surging data traffic is expected 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 due to 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 mounting volume of data being transmitted and processed globally intensifies the need 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 the fourth quarter of 2023 to the first quarter of 2024, mobile network data traffic experienced a 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 driving the growth of the underwater data center industry.
