Chiyoda Corporation, NYK, and its affiliate Knutsen NYK Carbon Carriers (KNCC) have completed a joint study evaluating the feasibility of the CCUS value chain, the companies said on January 31.
This study encompasses liquefaction, temporary storage, and the marine transportation of carbon dioxide, exploring three distinct methods: elevated pressure (EP), medium pressure (MP), and low ressure (LP).
The study focused on the MP and LP methods, involving Type-C tanks on liquefied CO2 carriers and large tanks at onshore storage facilities. In contrast, the EP method explores the use of cylinder tanks, based on existing pipeline manufacturing principles, for both liquefied CO2 carriers and onshore storage facilities.
The joint study has revealed that employing cylinder tanks for onshore storage facilities can significantly reduce construction periods, optimise land utilization, cut down on investment and operational costs, and enhance the energy efficiency required for operations, the companies stated.
The EP method, leveraging existing pipeline manufacturing principles, not only accelerates construction timelines but also proves to be an economically viable and energy-efficient alternative, the companies added.
