MHI testing CO2 liquefaction

Mitsubishi Heavy Industries (MHI) is testing a system that liquefies the CO2 captured from gas engine generator sets.

In this demonstration testing program, CO2 from gas engine generator sets, forming a part of an in-house power station at MHIET’s Sagamihara Plant, is captured by CO2MPACT, a compact CO2 capture system, and the CO2 is liquefied in MHI-AC&R’s compact CO2 liquefaction system. Because liquefied CO2 has less volume than gaseous CO2 and is more transportable, it is expected to accelerate adoption of Carbon dioxide Capture, Utilization and Storage (CCUS), the company said.

In addition, verification of operational support services using MHI’s proprietary remote monitoring system will be implemented in the CO2 liquefaction demonstration test program. It is the same verification as that for CO2 capture system which has already been underway in the demonstration test since 2022. The test program will lead to not only acquiring know-how relating to handling of liquefied CO2, but also creation of a fully integrated customer support system from CO2 capture to liquefaction.

MHI Group aims to achieve carbon neutrality by 2040, and the company is now undertaking strategic initiatives toward decarbonizing the energy supply side. Establishing a CO2 solutions ecosystem that links diverse carbon emission sources with solutions for storage and utilization is a core aspect of these initiatives. The CO2 liquefaction demonstration test program will enable all processes, from CO2 capture to liquefaction, to be conducted applying MHI Group’s comprehensive strengths. Going forward, MHI Group will continue further development of solutions, in a broad range of industrial fields including gas engine generator sets, that will contribute to environmental protection in response to the decarbonization needs of its customers and society, toward achieving a carbon neutral society.
