Mitsubishi Heavy Industries, Ltd. (MHI), and two of its Group companies – Mitsubishi Heavy Industries Engine & Turbocharger, Ltd. and Mitsubishi Heavy Industries Air-Conditioning & Refrigeration Corporation, have commenced joint demonstration testing of a system that liquefies the CO2 captured from gas engine generator sets. It will accelerate the quest efforts to achieve carbon neutrality by offering the liquefaction system and related technologies.

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 carbon capture system, and the gas is liquefied in MHI-AC&R’s compact CO2 liquefaction system. Introducing the expertise of the Research & Innovation Center which is in charge of R&D in MHI Group, the demonstration testing will target early practical application. As liquefied CO2 has less volume than gaseous CO2 and is more transportable, it is expected to accelerate the adoption of CCUS (Carbon dioxide Capture, Utilization and Storage).
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 the 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 the handling of liquefied CO2 but also the 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 carbon capture to liquefaction, to be conducted by 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 carbon neutrality.
