Nihon Shipyard and Mitsubishi Shipbuilding launch joint study for
Development of an Ocean-Going LCO2 Carrier-- Project Utilizing the Strengths and Knowledge of Both Companies
to Support the Emerging Era of Large-Scale Marine Transport of CO2 -♦ Project to utilize Nihon Shipyard’s wealth of shipbuilding experience in commercial ships andmarine structure and advanced technology capabilities, along with Mitsubishi Shipbuilding’s
knowledge regarding design and construction of liquified gas carriers.
♦ Aiming for completing construction at Nihon Shipyard from 2027 onwards.

Tokyo, May 22, 2023 – Nihon Shipyard Co., Ltd., a Tokyo-based joint venture for ship design and sales
between Imabari Shipbuilding Co., Ltd. and Japan Marine United Corporation and Mitsubishi Shipbuilding,a part of Mitsubishi Heavy Industries (MHI) Group, have started joint study for the development of an
ocean-going liquified CO2 (LCO2) carrier. Nihon Shipyard is pursuing this project with the aim of completing
construction of the vessel from 2027 onwards.

Demand for LCO2 carriers is expected to grow in the future as a means to transport large volumes of CO2
safely for CCS (Carbon dioxide Capture and Storage) projects, in which captured CO2 is stably storedunderground. Following the lead of the EU region, it is expected that CCS project in Asia will be accelerated
by the promotion of national governments, so it will be essential to establish a shipbuilding framework inJapan to meet the demand for LCO2 carriers.

This project will take advantage of the wealth of shipbuilding experience for various type of vessels andadvanced technology capabilities that Nihon Shipyard has accumulated over years, as well as theknowledge and advanced gas handling technology that Mitsubishi Shipbuilding has acquired in designingand constructing liquified gas carriers (liquified petroleum gas (LPG) and liquified natural gas (LNG)
carriers), as strengths that can be mutually supplemented.
Nihon Shipyard, in anticipation of future regulations restricting CO2 emissions, is proactively working
toward the commercialization of LNG and ammonia fueled ships. As its next initiative, the company isconsidering the potential for LCO2 carriers, aiming to further solidify its leading position in the industry.
MHI Group is pursuing strategic measures to strengthen its business for the energy transition. For its rolein this initiative, in addition to conventional shipbuilding centered on manufacturing, Mitsubishi Shipbuilding
aims to utilize its marine engineering technologies rooted in shipbuilding to contribute to the developmentof the maritime industry in Japan and around the world. This project is a part of that effort. Throughcollaboration with multiple Japanese shipping companies and with domestic/overseas energy companies,
and also construction of demonstration ship for transport of LCO2, Mitsubishi Shipbuilding is actively
pursuing the development of LCO2 carriers and commercialization of LCO2 shipping.
Going forward, Mitsubishi Shipbuilding and Nihon Shipyard will provide the world with the LCO2 carriers
necessary to establish a CCS value chain, and contribute to the realization of a carbon neutral world.
