CO2 Capture Demonstration Plant – Outline & Features
Plant Outline

Plant Features As part of the MoE’s Sustainable CCS Project, Toshiba has designed and constructed
the CO2 Capture Demonstration Plant, which captures more than 500 tons-CO2/day
from Mikawa Power Plant (more than 50% of its total emissions) The Demonstration Plant has been built and fully integrated with the Power Plant, withturbine extraction steam feeding the energy for desorbing CO2 at the stripper tower.
 The Mikawa Power Plant has a boiler capable of burning 100% biomass.
Consequently, the project has the potential to be one of the first BECCS project in the world.
