CCUS(CO2 Capture, Utilization and Storage)
Examples of CO2 Capture Initiatives From a variety of Flue Gas Sources
As a leader in CO2 capture technologies, MHI provides solutions around the world. We are engaged in initiatives to capture CO2 from a wide range of sources (see below).
Supplying plant to Petra Nova Carbon Capture (USA), the World’s Largest Post Combustion CO2 Capture Project
MHI has supplied a CO2 capture system to the Petra Nova Carbon Capture Project, the largest post combustion CO2 capture project in the world that targets coal combustion flue gas. It is located in the southern part of Houston, Texas, USA, and commenced commercial operation at the end of December 2016.
This is a large-scale enhanced oil recovery (EOR) project conducted by Petra Nova Parish Holdings LLC, a subsidiary of JX Nippon Oil & Gas Exploration Corporation.
The CO2 capture plant consists of flue gas pre-treatment (desulfurization), CO2 absorption and regeneration, CO2 compression, and utilities. It captures 4,776 tons of CO2 per day from a coal-fired power generation plant, which contains a high concentration of CO2 in its flue gas, with a CO2 capture rate(Note) of 90%.
(Note) CO2 capture rate (%): The ratio of CO2 captured by our CO2 capture plants to the amount of CO2 contained in combustion flue gas.
CO2 Capture Systems at Cement Production Facilities: Pilot Capture System (Canada) and FEED Contract for the UK's First CO2 Capture Plant
In 2023, MHI delivered and installed a small-sized CO2 pilot capture system called CO2MPACTTM for Heidelberg Materials, a major global cement manufacturer, at its cement plant in Edmonton, Alberta, Canada, and is conducting a demonstration test for CO2 capture.
Also in 2024, MHI is being deployed by Heidelberg Materials UK, for Front End Engineering Design (FEED), to further study the specifications of a CO2 capture plant at its Padeswood Cement Works in Flintshire, UK.
This project is a partnership between MHI and Worley, a global industrial engineering company of energy, chemicals and resources experts, and will implement the basic design of the CO2 capture plant using the Advanced KM CDR ProcessTM, our proprietary CO2 capture technology developed jointly with the Kansai Electric Power Co., Inc.
Through these projects, we are supporting Heidelberg Materials' vision of leading the decarbonization of the cement industry and promoting the establishment of a CCUS value chain.
Mitsubishi Shipbuilding Holds Christening and Handover Ceremony in Shimonoseki for Demonstration Test Ship for Liquefied CO2 Transport -- New Vessel "EXCOOL" to Contribute to Protecting the Global Environment --
Mitsubishi Shipbuilding Co., Ltd., MHI Group company based in Yokohama, held a christening and handover ceremony for a demonstration test ship to transport liquefied carbon dioxide (LCO2) in 2023. The ship will be used for the CCUS R&D and Demonstration Related Project / Large-scale CCUS Demonstration in Tomakomai / Demonstration Project on CO2 Transportation (the demonstration projects) being conducted by Japan's New Energy and Industrial Technology Development Organization (NEDO). The ceremony took place at the Enoura Plant of MHI's Shimonoseki Shipyard & Machinery Works in Yamaguchi Prefecture, in the presence of the ship owner Sanyu Kisen Co., Ltd. and other related parties.
CCUS (Carbon dioxide Capture, Utilization and Storage) is gaining attention as an effective means of achieving a carbon-neutral society. Because the sources of CO2 emissions are often located distant from the sites selected for carbon utilization or storage, demand is expected to increase for LCO2 carriers being able to transport such cargo safely and economically. MHI Group utilized its expertise and advanced gas handling technologies cultivated through the construction of liquefied gas carriers (both LPG and LNG types) to handle the entire design and construction of the vessel, including the cargo containment system.
