CO2 Capture Demonstration Plant – Outline & Features
As part of the MoE’s Sustainable CCS Project, Toshiba has designed and constructedthe CO2 Capture Demonstration Plant, which captures more than 500 tons-CO2/dayfrom Mikawa Power Plant (more than 50% of its total emissions)
The Demonstration Plant has been built and fully integrated with the Power Plant, with turbine 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.
