- KEY POINTS TO THE SOLUTIONS
- Given the economics outlined above, and the need to optimize each process in the value chain, it makes sense to work closely with a small number of stakeholders who have in-depth expertise and proven technology solutions in the CCS arena.
- To optimize the performance in the entire CCS value chain effectively, reducing the costs of sequestration, capture, and transportation is critical as they make up more than half of the overall cost.
MHI Provides Solutions that Enable Cost Optimization Across the Most Demanding Processes in the CCS Value Chain
To optimize performance and cost management for each process strategically, MHI can supply appropriate technologies for each process in CCS value chain: CO2 capture, compression, transportation, regasification, and pressurization. For CCUS, MHI also supports Enhanced Oil Recovery implementations.
MHI Delivered the World's Largest CO2 Capture Plant
In 2017, MHI America, collaborating with a partner firm, completed the construction of the world’s largest carbon capture plant in Texas, U.S.A. as the turnkey contractor. At the plant, 4,776 metric tons per day of CO2 is captured from a coal-fired thermal power plant to use for EOR.
Today, MHI has 13 commercial plants in operation and two under construction.
Shipbuilding Expertise Supports Effective CO2 Transportation
MHI’s renowned shipbuilding business is responding to the industrial demands for long-distance CO2 transport and flexible ship sizes.
For more than 150 years, MHI has been at the cutting edge of ship-building and innovative technology development for the shipping sector.
For transporting sequestered carbon, the company can draw on its expertise of building liquefied petroleum gas (LPG) carriers as these have the same architectural model as the LCO2 ships needed in the CCS value chain.
To reduce the cost of long-distance transportation, it is desirable to increase the size of the vessel. But liquefied CO2 needs to be stored under low temperature and high-pressure conditions. To avoid it solidifying and to maximize the size of the vessel, it is necessary to adopt low-pressure LCO2 handling technology.
MHI has been contributing to the development of LCO2 shipping technology for more than 20 years, working on both the company’s own and government-led R&D projects.
MHI is transferring its expertise in LPG and LNG handling technology to low-pressure LCO2 handling on land and offshore, working on this new technology development with its group companies and its research and innovation center. Initial plans for an LCO2 ship capable of both domestic shipping (approximately 6,000 km) to ocean-going shipping (more than 20,000 km) are complete.
A Partner for the Carbon Capture Journey
In applying its many years of experience - gained as part of large projects in the U.S. and Europe - and innovation capabilities in the CCS value chain, MHI is dedicated to contributing to the prevention of global warming.
