Toyo Engineering Corporation (TOYO) has signed a Memorandum of Understanding (MOU) with SLB OneSubsea (OneSubsea), the world’s leading subsea technology and solutions provider, to explore collaboration opportunities in subsea CCS (CO2 storage below the seabed). Through this MOU, the companies aim to combine their respective strengths to develop optimized and highly feasible system solutions for subsea CCS projects, primarily in Japan and Southeast Asia.

As the world moves toward carbon neutrality, CCS is recognized as one of the most effective ways to reduce CO2 emissions. Globally, many geological formations capable of safely storing CO2 over the long term are located beneath the seabed. As a result, expanding CCS will require an integrated approach that combines onshore facilities with subsea systems.

At the same time, subsea CCS projects capable of handling large volumes of CO2 at commercial scale present technical challenges unique to offshore storage, including the safe transport and injection of CO2, as well as advanced operation and maintenance.

TOYO brings strong capabilities in optimizing CCS project development and engineering, including system integration across capture, transportation, and storage interfaces, as well as the design and engineering of onshore facilities. OneSubsea, meanwhile, has a proven global track record in subsea technologies, including subsea production and processing systems. By working together, the two companies believe they can offer optimized subsea CCS system solutions tailored to a diverse range of customer needs and project conditions.

Key Areas of Collaboration

In the subsea CCS field, the two companies will jointly explore:

Collaboration opportunities and marketing strategies
Integrated and optimized system design

TOYO and OneSubsea will initially explore opportunities across a wide range of subsea CCS projects in Japan and Southeast Asia, with the aim of addressing customers’ technical challenges associated with subsea CO2 transport, injection, and storage. By combining their expertise and technologies, the two companies aim to create new value in subsea projects and contribute to the realization of a decarbonized society.
