Some chemical CO₂ solvents are suitable for CO₂ capture under relatively low pressure conditions from large-scale CO₂ generation sources, such as the flue gases emitted by coal-fired power plants (Post Combustion Capture) or the blast furnace gases from steel-making plants.
 

In previous studies, we achieved our targeted CO₂ capture energy consumption rate of 2.0 GJ/t-CO₂. Moreover, we successfully developed novel solvent systems that enabled CO₂ desorption at temperatures below 100 °C, lower than the temperature of 120 °C required by conventional systems.
 

Currently, we are conducting the COURSE 50 Step 2 project. This project began in 2013 and is scheduled to finish in 2017 and has the goal of developing high performance CO₂ solvents that will reduce the costs associated with CO₂ capture to below 2000 JPN/t-CO₂ in the steel-making industry.
