Maritime CO₂ transportation solutions support the transition to low carbon economy

Liquefied CO₂ carriers are intentionally built to efficiently transport liquefied carbon dioxide at low temperatures and high pressures to the location of storage or usage. These carriers are an economical option for transporting carbon dioxide produced by power plants, steelworks, and chemical factories.

FEATURES

A comprehensive range of CCUS solutions

To facilitate the transition to a low-carbon economy, work is currently underway to establish a global CCUS (Carbon Capture, Utilization and Storage) value chain that will entail the transportation of a projected 1 billion metric tons of CO₂ every year. In addition to carriers, the MHI (Mitsubishi Heavy Industries) group also supplies CO₂ recovery equipment, compressors, and related systems. MHI is also involved in the development of CO₂NNEX™, a digital platform for visualizing and optimizing the movement of carbon dioxide around the globe.

Accredited LCO₂ transportation technology

The MHI group has been building ships since 1857 and has extensive experience with the design and construction of LNG and LPG carriers. MHI is now taking its expertise in shipbuilding to supplement the transport and handling of cryogenic liquefied gases and applying it to liquefied CO₂ (LCO₂) carriers. Liquefied CO₂ (LCO₂) carriers the transportation of liquefied carbon dioxide at high pressure and low temperatures is subject to international technical and safety regulations stipulated by classification societies. The cargo tank system developed by Mitsubishi Shipbuilding has been granted Approval in Principle (AIP) by classification society Bureau Veritas , attesting to the fact that it meets technical and safety requirements. The carrier’s larger tanks also contribute to increased efficiency and reduced costs.

LCO₂ Carriers indispensable for long-distance transport

Carbon dioxide is primarily transported by pipelines or ships. While pipelines are more cost-effective over short distances, for longer distances over 300 km, ships are seen as delivering greater economic benefits. As a result, several Japanese and European projects are currently underway will use LCO₂ carriers to transport CO₂ for storage.
