Most CO2 removal systems at the thermal power plants demand the vast energy of the steam for the power generation, which lowers the performance and increases the cost. Therefore reducing the energy consumption is inevitable for introducing the CO2 removal system into the thermal power plant.We have achieved the energy consumption of 2.6GJ/t-CO2 at a condition of 90% CO2 capture ratio at our 10t-CO2/day pilot plant in February 2011 using the flue gas from the coal fired boiler of the Mikawa power plant. This is the first time in the world that the consumed energy of much lower than 3.0 GJ/t-CO2 has been proved at a 10t- CO2/day scale pilot plant using the actual flue gas of the coal fired power plant, not only by simulations. According to the heat loss test and analysis, it would be reduced more 0.3 GJ/t-CO2 by reinforcing the thermal insulation, which means 2.3GJ/t-CO2 would be possible at larger scale commercial plant.Since the pilot plant had completed in September 2009, we have been operating it continuously using the flue gas from the coal fired boiler. Then we have reached the 6,809 hour cumulative operating time which includes more than 3,000 hour operating time exceeding the planning values of 10t-CO2/day and 90% CO2 capture ratio. This means our excellent solvent called TS-1 (Toshiba Solvent 1) has enhanced durability and reliability because any definite degradation by SOX, NOX and oxidization has not been emerging during the operation.Furthermore we are reconstructing the pilot plant again and planning the next performance test starting in March 2012 targeting the less energy consumption
