Chiyoda Corporation, Nippon Yusen Kabushiki Kaisha, and Knutsen NYK Carbon Carriers have signed a memorandum of understanding to jointly explore carbon capture and storage deployment across global markets.
The agreement focuses on integrating onshore capture infrastructure with marine transport and offshore injection systems, a combination that reflects the industry’s current bottleneck rather than its technological frontier.
The CCS value chain is increasingly constrained not by capture capability but by the ability to move and store CO2 efficiently. For industrial emitters without direct access to geological storage, shipping liquefied CO2 has emerged as a flexible alternative to pipeline networks. However, the lack of standardization in transport conditions continues to complicate project economics.
The partnership centers on evaluating three transport modes for liquefied CO2: low pressure, medium pressure, and elevated pressure systems. Each configuration presents trade-offs between energy consumption, liquefaction requirements, vessel design, and storage compatibility. Elevated pressure systems can reduce liquefaction intensity but may increase vessel complexity, while low-pressure systems align more closely with existing cryogenic shipping infrastructure but require deeper cooling and higher energy input.
These variables translate directly into capital expenditure and operating cost uncertainty. Without established benchmarks across full-scale projects, developers are still relying on modeled assumptions rather than operational data, limiting financial clarity for investors and policymakers.
The structure of the collaboration reflects the segmented nature of CCS deployment. Chiyoda will focus on onshore terminal development, including capture integration, liquefaction facilities, and temporary storage, as well as regulatory compliance. This stage is critical, as capture and liquefaction determine the physical state and quality of CO2 entering the transport system.
NYK Line will lead coordination efforts and assess marine transportation logistics across pressure configurations. Shipping remains one of the least mature components of the CCS chain, with limited commercial-scale experience in CO2 transport compared with liquefied natural gas. Vessel design, routing efficiency, and loading infrastructure are still evolving, particularly for multi-source aggregation models.
KNCC’s role extends into offshore operations, including direct injection and floating solutions for liquefaction and storage. Offshore injection introduces additional technical and regulatory complexity, particularly in cross-border projects where liability frameworks for stored CO2 remain underdeveloped.
Prior Study Highlights Gaps Between Engineering and Deployment
The companies’ collaboration builds on a 2024 joint study that evaluated cost structures and timelines across the entire liquefied CO2 value chain. The study compared low, medium, and elevated pressure transport systems and identified key barriers to large-scale implementation, including infrastructure integration, permitting timelines, and public acceptance.
Such studies are increasingly central to CCS development, as the industry lacks a large dataset of operating projects. While pilot and demonstration facilities provide technical validation, they do not fully capture the logistical and economic complexity of multi-source, cross-border CO2 networks.
The ability to translate these findings into project-specific value chain designs will determine whether CCS can move beyond isolated industrial clusters into broader deployment. Customization is necessary because storage sites, emission sources, and regulatory environments vary significantly across regions.
Japan’s Strategic Position in CCS Supply Chains
Japan’s involvement reflects its structural position as a major industrial emitter with limited domestic storage capacity. This constraint has driven interest in international CCS value chains, where captured CO2 is transported to offshore or overseas storage sites.
Shipping-based CCS solutions are particularly relevant in this context, enabling flexibility in routing and storage selection. However, this approach also introduces geopolitical and regulatory dependencies, as cross-border CO2 transport requires alignment on liability, monitoring, and long-term storage obligations.
The partnership’s global scope suggests an effort to position Japanese engineering and shipping capabilities within emerging international CCS networks. Whether this translates into commercial-scale deployment depends on the ability to align technical solutions with regulatory frameworks and long-term storage agreements.
One of the more technically complex elements under consideration is the use of floating infrastructure for liquefaction, storage, and injection. Floating systems could reduce the need for extensive onshore development and enable deployment in regions without existing port or pipeline infrastructure.
However, floating CCS introduces additional cost layers and operational risks. Offshore environments require robust engineering to manage pressure, temperature, and safety constraints, while also ensuring continuous injection into geological formations. These systems must operate reliably over long time horizons, as storage integrity is a core requirement for regulatory approval and environmental credibility.
