MHIENG’s first compact CO2 cap

– Fully integrated customer support package to follow –

– On-site use of CO2 captured at the power plant will make the entire suburb of Seifu Shinto carbon negative
– Using proprietary CO2 capture technologies, MHIENG provides various solutions for small-scale installations

TOKYO, June 30, 2022 – (JCN Newswire) – Mitsubishi Heavy Industries Engineering, Ltd. (MHIENG), part of Mitsubishi Heavy Industries (MHI) Group, has started full-scale operation, on schedule, of a compact CO2 capture system ordered in November 2021 by Taihei Dengyo Kaisha, Ltd. This is the first system of its type to enter commercial operation.

The compact CO2 capture system was installed in a 7 megawatt (MW) class biomass power plant operated by Taihei Dengyo in Seifu Shinto, a suburb of Hiroshima city. The system has the capacity to capture 0.3 metric tons per day (tpd) and is based on a very versatile standardized design requiring an installation space of only five meters long and two meters wide. Its modular configuration allowed rapid transport to site and easy installation.

The CO2 captured from the factory’s flue gases will be used to grow vegetables in on-site greenhouses – an example of a circular economy. By fully consuming all the CO2 captured in its carbon-negative power plant, Taihei Dengyo seeks to help prevent global warming and promote a low-carbon society. The biomass power plant where the system was installed was delivered by Mitsubishi Heavy Industries Power IDS, Ltd. in October 2019.

In the next step, MHIENG will conduct a demonstration test of operational support services for the plant using a proprietary remote monitoring system with the customer. MHIENG ultimately aims to build a fully integrated customer support package, encompassing everything from system design and delivery to after-sales service, operation and maintenance. MHIENG also plans to expand its range of compact CO2 capture systems as well as reduce installation, operation and maintenance costs and accelerate deliveries. This will enable it to offer various solutions to customer needs, especially relatively small-scale industrial and other facilities.

The MHI Group is currently strengthening its position in the energy transition and the development of an ecosystem of CO2 solutions is at the heart of this initiative. Carbon Dioxide Capture, Utilization and Storage (CCUS) is gaining attention as an effective way to achieve a carbon neutral society.

MHIENG, as a leading decarbonization company and key to the group’s energy transition strategy, will continue to contribute to the large-scale reduction of greenhouse gas emissions by introducing its CO2 capture technology to high performance on a global scale. It will also forge ahead in the development of new solutions to contribute to the protection of the global environment.

About MHIENG CO2 Capture Technologies

Since 1990, MHIENG (originally MHI) has undertaken the development of the KM CDR process (Kansai Mitsubishi Carbon Dioxide Recovery Process) and the Advanced KM CDR process with The Kansai Electric Power Co., Inc. (KEPCO). As of June 2022, MHIENG has delivered 14 commercial plants adopting the KM CDR process, and two more plants are currently under construction. This solid experience makes MHIENG a world leader in CO2 capture technologies.
