The 40,000 cubic metre liquefied carbon dioxide (LCO₂) carrier design developed by Greek carbon capture, utilisation and storage (CCUS) service provider ECOLOG in partnership with Hanwha Offshore and UK-based engineering firm Babcock LGE has received Approval in Principle (AiP) from the American Bureau of Shipping (ABS).
In September 2023, Hanwha Offshore, ECOLOG, Babcock LGE, and the American Bureau of Shipping (ABS) signed a Joint Industrial Project (JIP) for the collaborative development of a 40,000 m3 LCO₂ carrier. Under the JIP, Hanwha Marine is responsible for the hull and liquid cargo tank design; Babcock LGE is responsible for providing expertise in cargo handling systems and integration. The award of the AiP is the result of extensive collaboration during the detailed design development phase of the project.
The LCO₂ carrier takes into account the key characteristics of liquefied CO₂, featuring low pressure and shallow draught, which collectively aim to maximise energy integration and reduce greenhouse gas emissions.
ECOLOG noted that as a midstream CO2 service company, it is committed to achieving net-zero emissions in support of urgent action against climate change. With its knowledge of cryogenic gas transport and how LCO₂ transport fits into the wider CCUS supply chain, ECOLOG has contributed to this joint industrial project. It was also said that the resilience and commercial impact of various CO2 components on the versatility of cargo containment systems and cargo handling systems was a key consideration in the AiP study.
ECOLOG is said to be committed to building and owning a fleet of LCO₂ carriers to serve the emerging CCUS industry. The company's strategy is to utilise its midstream infrastructure, including vessels and terminals, to connect hard-to-abate emissions to cost-competitive sequestration sites and high-value reuse facilities. Within the CCUS supply chain, ECOLOG is developing the world's first large-scale CO2 service platform.
The new LCO₂ carriers awarded the AiP are capable of transporting large quantities of liquefied carbon dioxide, which can significantly improve operating costs, Hanwha Marine said.
Working with ECOLOG, Hanwha Ocean and ABS, the company's ecoCO₂® solution ensures the optimisation of CCUS value chain parameters, including shipping profiles, loading and unloading terminal parameters, cargo composition, and cargo volumes,’ noted Babcock LGE. This AiP marks an important milestone in the decarbonisation process."
In April this year, American Bureau of Shipping, on behalf of the Bermuda Flag Administration, has awarded ECOLOG the industry's first ISM compliance document for the operation of an LCO₂ carrier. Recently, the company also launched a liquefied natural gas (LNG) dual-fuel powered LCO₂ carrier with sail and shore power.
