MHIENG to deliver compact CO2 capture system to biomass power plant

Mitsubishi Heavy Industries Engineering (MHIENG), a group company of Mitsubishi Heavy Industries, has received an order for a compact CO2 capture system for a biomass power plant in Japan.

The order comes from Taihei Dengyo Kaisha, a provider of plant construction, maintenance, and auxiliary services. The CO2 capture system offers a capacity of 0.3 tonnes per day.

Taihei Dengyo is targeting the establishment of carbon-negative solutions from carbon-neutral systems, to help achieve a circular society. The firm aims to achieve this shift through the separation, capture, and initial storage of the CO2 emitted by biomass power plants, followed by the use of the stored carbon to grow plants, for example.

The introduction of a newly ordered compact CO2 capture system forms part of this initiative. Plans call for its integration into a 7 MW class biomass power plant operated by Taihei Dengyo at an urban complex in Hiroshima City.

The system is based on a test plant manufactured to verify the impact of applying the new CO2 capture system to a biomass flue gas source, which made early commercialisation possible. The base system is a pilot facility used in the BECCS project conducted at a biomass power plant owned by Drax.

The CO2 capture technology adopted in the new system is the KM CDR Process™, jointly developed by MHIENG and Kansai Electric Power Co, which employs the high performance KS-1™ amine solvent. It significantly reduces energy consumption.

As of November, MHIENG has delivered a total of 13 commercial plants using the KM CDR Process at locations globally, and two more are currently under construction.
