MHI, KEPCO to install CO2 capture plant at Japanese CCGT

Mitsubishi Heavy Industries (MHI) has joined forces with Kansai Electric Power Co. (KEPCO) to establish a CO2 capture pilot plant at 2.9 GW Himeji No.2 gas-fired power plant in Hyogo, Japan, it said on January 17.

This new plant is being established to demonstrate the next-generation CO2 capture technology as a substitution for the existing pilot plant installed at Nanko Power Station in 1991, and MHI aims to start operation in FY2025.

Designed for research and development of CO2 capture technology, the pilot plant will utilise flue gas from the gas turbine at Himeji No.2 power station, boasting a capture capacity of approximately 5 tonnes/day.

One of the key innovations of this project is the integration of a remote monitoring system, ΣSynX (Sigma Syncs) Supervision, part of MHI's digital innovation brand. This system enables real-time monitoring of the plant's operations from the MHI Yokohama Building and other locations, allowing for automated control and remote operation start-stop capabilities.
