A compact carbon dioxide (CO2) capture system has become the first of its kind to go into commercial operation after its integration into a 7-megawatt (MW) class biomass power plant in Hiroshima City, Japan.

Announced yesterday, 30th June, the engineering arm of Mitsubishi Heavy Indistries (MHI) Group – MHI Engineer, Ltd. (MHIENG), installed the system for its client Taihei Dengyo as part of the company’s efforts to decarbonise heavy industry. 

Capable of capturing 0.3 metric tonnes of CO2 per day, the easily transportable and compact, modular nature of the system sees it requiring an installation space of just five metres in length and two metres wide.

Captured from the plant’s flue gas, the CO2 will be utilised to help grow vegetables in on-site greenhouses, contributing to a circular economy. 

“As the next step, MHIENG will perform demonstration tests of operational support services for the plant using a proprietary remote monitoring system with the customer,” the company stated. 

“MHIENG also has plans to expand its line-up of compact CO2 capture systems as well as to pursue reduced installation, operation and maintenance costs and faster deliveries.” 

By focusing on solutions around carbon capture, utilisation, and storage (CCUS), MHI Group aims to advance the energy transition as part of its emission reduction strategy.
