Launch of the CO2 Capture Pilot Plant

In a significant advancement towards achieving carbon neutrality, Mitsubishi Heavy Industries has inaugurated a new CO2 capture pilot plant at the Kansai Electric Power's Himeji Second Power Plant on May 14. This facility is critical for the research and development of carbon capture technologies, utilizing exhaust gases from the power station's gas turbines. The pilot plant boasts a capture capacity of approximately 5 tons per day, contributing to the ambition to strengthen the competitiveness of Carbon Capture, Utilization, and Storage (CCUS) initiatives.

A Legacy of Innovation in CO2 Capture

Since 1990, Mitsubishi Heavy Industries has partnered with Kansai Electric Power Company in progressive research and development of innovative CO2 capture technologies. The recent activation of this pilot plant enhances the research infrastructure, allowing for advanced validation tests using cutting-edge equipment. This capability is designed to meet diverse customer needs beyond just regulatory compliance with greenhouse gas emissions, ensuring that a variety of environmental demands can be addressed at a higher level.

In 2022, Mitsubishi Heavy also announced a collaboration with ExxonMobil to develop next-generation CO2 capture technologies. The pilot plant serves as a testing ground for these advancements, focusing on research and development aimed at reducing both environmental impact and operational costs. Additionally, the plant incorporates the ‘ΣSynX Supervision’ remote monitoring system, reflecting Mitsubishi's commitment to digital innovation in this field.

Commitment to Carbon Neutrality

Mitsubishi Heavy Industries has declared its mission to achieve carbon neutrality by 2040, under the initiative known as MISSION NET ZERO. This commitment drives strategic efforts to decarbonize both the demand and supply sides of energy. Central to their decarbonization strategy—identified as the “Energy Transition”—is the construction of a CCUS value chain that connects a diverse array of CO2 emission sources with storage and reuse solutions.

To bolster this initiative, the company is focused on enhancing its proprietary CO2 capture technology and promoting CCUS as a robust solution provider. These efforts are aimed at making a global contribution to reducing greenhouse gas emissions and advancing environmental protection through innovative solutions.

Advanced CO2 Capture Technologies

Mitsubishi Heavy has been at the forefront of CO2 capture technology, developing processes like the KM CDR ProcessTM and the Advanced KM CDR ProcessTM since 1990 in collaboration with Kansai Electric Power. As of May 2025, 18 facilities employing these technologies have been delivered successfully. The Advanced KM CDR ProcessTM utilizes an improved amine absorbent known as KS-21TM, which is noted for its superior regeneration efficiency, lower degradation, and remarkable energy-saving performance, all while reducing operational costs and minimizing amine emissions.
