Global Submarine Carbon Dioxide Storage Market Strategic Research Report

Scope of the Report

The global Submarine Carbon Dioxide Storage market size is predicted to grow from US$ 1,193 million in 2025 to US$ 2,153 million in 2032; it is expected to grow at a CAGR of 9.0% from 2026 to 2032.

Submarine carbon dioxide storage (SCDS) refers to a systematic solution that uses engineering techniques to inject and permanently store captured carbon dioxide within specific geological structures beneath the seabed. This technology primarily utilizes sealed geological bodies such as deep saline aquifers and depleted oil and gas reservoirs buried beneath the seabed. Through physical sealing by overlying dense rock layers, capillary forces, and mineral solidification mechanisms, it achieves the safe isolation of supercritical carbon dioxide over millennia. Compared to onshore storage, its significant advantages lie in its distance from human settlements, its enormous storage potential, and its minimal impact on terrestrial ecosystems, making it particularly suitable for handling concentrated emissions from coastal industrial corridors. Currently, this technology has been commercially validated in areas such as the North Sea and Brazilian waters. Its core technological components include seabed geological exploration, drilling engineering, long-term monitoring, and risk assessment, and it is gradually becoming an indispensable deep-sea key technology pathway in the global carbon neutrality strategy.

The submarine carbon dioxide storage industry is at a critical juncture, transitioning from demonstration projects to commercial operation. Several large-scale projects are currently operational globally, with Norway's "Equinor" project being the most representative, marking the formation of a transnational carbon transport and storage business model. Current projects primarily focus on the revitalization of depleted oil and gas fields, mainly located in the North Sea, Brazilian waters, and Australian waters.

The next five years will see three major trends: first, breakthroughs in floating storage technology will open up new markets for deep-sea storage; second, improved regulatory frameworks will promote cross-jurisdictional cooperation in storage; and third, innovative monitoring technologies will enable real-time 3D visualization of stored materials.

The global development of submarine carbon dioxide storage exhibits a pattern of "North Sea leadership, followed by multiple regions." The European North Sea region holds a dominant position due to its mature oil and gas infrastructure, clear carbon pricing mechanisms, and strong government support, with Norway and the UK spearheading the construction of regional storage hubs. North America is accelerating the implementation of projects in the Gulf of Mexico through tax incentives. The Asia-Pacific region, represented by China, Australia, and South Korea, is actively assessing coastal storage potential and launching pilot projects. Brazil in South America is leveraging pre-salt oil fields for enhanced oil recovery coupled with storage. Current development is limited by the lack of transnational transport agreements and inconsistent monitoring standards. Future breakthroughs will focus on establishing an international responsibility framework and cross-border storage cooperation mechanisms to make this technology a key support for the global carbon neutrality strategy.
