MOL Completes Ammonia/Liquefied CO2 Carrier Concept Study

Mitsui O.S.K. Lines, Ltd. (MOL) announced it recently completed a concept study on an ammonia/liquefied CO2 carrier intended to flexibly meet future demand for transport of liquefied CO2 and ammonia transport. The Japanese shipping company said it worked with the Mitsubishi Heavy Industry (MHI) Group's Mitsubishi Shipbuilding Co., Ltd. on this research.

According to MOL, its liquefied CO2 carrier (LCO2 carrier) concept is being developed in hopes that it will play a key role in efficiently transporting captured liquefied CO2 to storage reservoirs or usage sites in the value chains of carbon dioxide capture utilization and storage (CCUS), which is drawing attention amid global efforts to decarbonize.

In addition, MOL noted growing interest in ammonia as a next-generation clean energy source that does not emit CO2 during combustion. The movement to strategically use ammonia is increasing under the global trend toward decarbonization.

Like the LCO2 carrier, for which a concept study was completed in November 2021, the cargo tank capacity of the "ammonia/liquefied CO2 combined carrier," is set at around 50,000m3 on the assumption of the future liquefied CO2/ammonia market.

MOL entered the liquefied CO2 ocean transport business through investment in Larvik Shipping AS, which has managed LCO2 carriers for industrial customers in Europe for over 30 years. The company said it continues to study ways to realize the LCO2 carrier to meet customer needs, while drawing upon its accumulated expertise in safe vessel operation and LS's know-how and track record, to contribute to the worldwide growth of the liquefied CO2 ocean transport business.
