Mitsui O.S.K. Lines, and Mitsubishi Shipbuilding  a part of Mitsubishi Heavy Industries  Group, have acquired Approval in Principle  from Nippon Kaiji Kyokai  for their jointly developed liquefied CO₂  / methanol carrier. AiP acquisition for this type of carrier marks a world’s first

Technologies for converting CO₂ into fuel or chemical products are attracting attention as a means of utilizing CO₂ in CCUS (Carbon dioxide Capture, Utilization and Storage). One such approach is the ongoing study toward realizing a supply chain for producing synthetic methanol^(Note3) from capturedCO₂. Synthetic methanol is expected to serve as one of the marine fuels that will contribute to decarbonization in the maritime shipping industry.

The vessel for which Mitsubishi Shipbuilding and MOL acquired AiP is based on a low-pressure LCO₂ carrier. It aims to transport CO₂, which serves as raw material, on outward voyages and synthetic methanol on return voyages. Use of dedicated vessels for CO₂ or methanol results in empty-cargo operation on half of their trips. If dual transport of CO₂and methanol is achieved, empty-cargo trips can be eliminated, thereby improving overall transport efficiency. MOL and Mitsubishi Shipbuilding will move forward with the development of the LCO₂ / methanol carrier, building on the findings and technical challenges identified during the concept study. The goal is to achieve commercialization of the LCO₂ / methanol carrier through collaboration with relevant companies in the supply chain and other partners.

The MOL Group is currently working to build supply chains for synthetic fuel/methanol and CO₂ through initiatives such as its investment in HIF Global LLC^(Note4), a U.S.-based company that develop, produce and transport synthetic fuel/methanol across North and South America and Australia. LCO₂ / methanol carrier is expected to enhance the overall economic viability of such supply chains and contribute significantly to their realization. In line with the “MOL Group Environmental Vision 2.2,” MOL is targeting net-zero emissions Groupwide by 2050. By further accelerating initiatives to transport CO₂ as well as to develop and supply synthetic methanol, MOL aims to contribute to realization of a low-carbon or decarbonized society.

MHI Group is currently pursuing strategic measures to strengthen its business for the energy transition. In conjunction with this initiative, Mitsubishi Shipbuilding is making efforts to contribute to the advancement of the maritime industries in Japan and around the world by utilizing its shipbuilding-based marine engineering technologies in addition to conventional shipbuilding. The development of LCO₂ / methanol carrier is one example of these efforts. Collaboration with MOL also demonstrates MHI Group’s commitment to partnerships. Moving forward, Mitsubishi Shipbuilding will continue to build strategic global partnerships both to incorporate external expertise and actively advance the development of a CCUS value chain. Through these efforts, the company aims to provide its technologies, products and services to ever more customers.
