It will demonstrate a carbon capture and storage solution developed by MHI in partnership with ExxonMobil aimed at reducing environmental loads and costs.
Mitsubishi Heavy Industries (MHI) has announced that a new carbon capture pilot at KEPCO's Himeji No.2 power plant in Hyogo Prefecture, Japan, has started operating.
The Himeji No.2 thermal power plant runs on LNG, consists of 6 units and has a maximum output of 2,919,000kW.
The pilot plant was established to conduct demonstration tests, as well as research and development for carbon capture technologies using flue gas from the gas turbines.
The plant has a capture capacity of approximately five tonnes per day.

It will demonstrate an end-to-end carbon capture and storage solution developed by MHI in partnership with US firm ExxonMobil, aimed at reducing environmental loads and costs.
MHI will also implement a remote monitoring system at the plant.
MHI has been collaborating with ExxonMobil on carbon capture tech since 2022 and developing CO2 capture technologies in collaboration with KEPCO since 1990.
Together with KEPCO, MHI Group has been developing what they refer to as the KM CDR Process (Kansai Mitsubishi Carbon Dioxide Recovery Process) and the Advanced KM CDR Process. The Advanced KM CDR Process utilises the KS-21 solvent. This solvent incorporates improvements over the amine-based KS-1 and offers superior regeneration efficiency and lower deterioration than its KS-1 counterpart. It also results in low amine emissions, according to MHI.
