Mitsubishi to test direct engine carbon capture

The demonstration marks MHIENG’s first attempt at capturing CO2 from gas engine flue gas

Two divisions of Mitsubishi Heavy Industries (MHI) will launch a demonstration test of carbon capture technology in a gas engine generator set.

Mitsubishi Heavy Industries Engineering, Ltd. (MHIENG)’s CO2 capture technology will be installed on a generator set operated by Mitsubishi Heavy Industries Engine & Turbocharger (MHIET).

The demonstration marks MHIENG’s first attempt at capturing CO2 from gas engine flue gas, the companies said. Tests will begin in July and last 10 months.

The tests will be carried out using a compact CO2 capture system manufactured by MHIENG and installed in gas engine generator sets forming a part of an in-house power station at MHIET’s Sagamihara Plant in Japan. The demonstration testing will be applied to study the impact of gas engine flue gas properties on capture performance, and to evaluate the component makeup of the captured CO2. Verification will also be performed on an operation support service utilizing MHIENG’s proprietary remote monitoring system. A fully integrated customer support structure will be put in place encompassing all aspects from CO2 capture system introduction plans for gas engines and other facilities, to after-sale services, maintenance and operation. In addition, a mass-production type compact CO2 capture system will be adopted and the system’s ease of installation and appropriateness for use in relative small-scale facilities will be evaluated, to enable enhancement of the system’s overall reliability.

MHIET intends to invite customers to tour the Sagamihara Plant while testing is underway. Plans also call for the captured CO2 to undergo liquefaction testing to facilitate its handling, conducted jointly with the Research & Innovation Center in charge of R&D at MHI Group. In this way, the MHI Group will strive as a whole toward early realization of utilization of captured CO2.

Mitsubishi Heavy Industries plans to test carbon capture on gas engines.

MHI Group said it is strengthening its position in the Energy Transition, and the development of a CO2 solutions ecosystem is a core component of that initiative. Carbon dioxide capture, utilization and storage (CCUS) is garnering attention as an effective means for realizing a carbon neutral society. Supporting the group’s strategy on the Energy Transition, MHIENG, as a leading company in the decarbonization area, will continue to help achieve wide-scale greenhouse gas emission reduction by introducing its high-performance CO2 capture technology globally. It will also press ahead in developing new proprietary technologies to contribute to global environmental protection. MHIET, as a manufacturer of gas engine generator sets, will seek to offer environmentally friendly gas engines with CCUS to various customers as a choice toward carbon free society.
