PROS:- Capture process after boiler simplified- Little penalty associated with capture itself

CONS:- Energy penalty and cost required for ASU- Plant operational flexibility - Additional equip required for CO2 purity- No partial capture configuration possible

PROS:- Process proven in chemical industry- Adaptable to new build, existing retros- Adaptable to other emitters (steel, cement)- Partial capture configuration possible

CONS:- Energy penalty for capture- Equipments tend to be larger than other techs

PROS:- Capture equipments smaller (high pressure)- Capture energy penalty smaller

CONS:- Energy penalty and cost required for ASU- IGCC lacks operational flexibility of CC - Only new build application- No partial capture configuration possible

Ministry of the Environment Sustainable CCS ProjectOutline of the Project(1) CO2 Capture from the Mikawa Power Plant･ CO2 capture facility to be designed and constructed to capture more than 500 tons of CO2 per day.

(500 tons of CO2 per day is about 50% of the daily emissions from the 49 MW Mikawa Power Plant)･ The plant will be used to evaluate performance of technology under various operating conditions,

cost and environmental aspects of the amine-based post-combustion chemical absorption technology.(2) Establishing a Socio-political Environment for the Introduction of CCS in Japan･ Research on aspects including socio-economics and policies to establish an enabling environment

necessary for the smooth introduction of CCS in Japan.･ Develop basic concepts toward an integrated CCS system, with aims to achieve practical applications

of the capture technology by 2020.

Project Leader : Dr. Makoto Akai (Emeritus Researcher at AIST)


The CO2 Capture Demonstration Plant will be designed and built to capture more than 500 tons-CO2/day from Mikawa Power Plant (more than 50% of its total emissions)

The Capture Plant will be built and fully integrated with the Power Plant, with turbine extraction steam feeding the energy for regeneration of CO2 at the stripper tower.

The old coal boiler was replaced with a boiler capable of also burning 100% biomass. The new boiler is now fully operational and normally operating on biomass fuel. Consequently, the project may become one of the first BECCS project in the world.

Summary

Toshibaʼs present activity in development and deployment of post combustion CO2 capture technology started in full with the commencement of the Mikawa Pilot Plant in 2009.

The Mikawa Power Plant has been proposed by Toshiba to the MoE and selected as the site for its CO2 Capture Demonstration Project. It is now under construction, and is planned to start demo operation in FY2020.

Toshiba will continue to deploy this technology, and optimally integrate this with improvement on efficiency in the power plant, to substantially decrease its carbon emission footprint.
