Toshiba Corporation announced that it will accelerate development of its carbon capture technology by installing a pilot plant at Sigma Power Ariake Co. Ltd.'s Mikawa Power Plant, in Omuta City, Fukuoka Prefecture. Construction of the plant is scheduled to start in spring 2009, and the commissioning and validation testing is expected to begin in August.
CO2 separation and capture is an integral part of carbon capture and storage (CCS) system, along with subsequent storage of the gas. At the Mikawa pilot plant, Toshiba will deploy and validate its latest advances in separation and capture technology.
An effective separation and capture system must operate stably while minimizing the economic impact on the plant's operation costs. Toshiba has succeeded in developing an amine solvent that consumes minimal energy during CO2 separation and capture, and has confirmed on a bench-scale test that it matches industry leading standards.
The Mikawa pilot plant is designed to capture 10 tons of CO2 a day from the boiler flue gas of the coal fired thermal power plant. Beyond proving system performance, plant verification will encompass a wide range of tests aimed to accumulate know-how required for the design of utility-scale power plant application. These include the effects of the thermal power plant flue gas contents, such as SOx (sulfur oxide), on the operation of the system when integrated with other power plant equipment, such as turbines and boilers.
Toshiba is targeting installation of its system in demonstration plants in Japan and overseas in parallel with the validation tests at the Mikawa pilot plant. Toshiba's goal is to meet emerging needs for commercial scale CCS systems for thermal power plants, an area where demand is expected to grow from around 2015. Toshiba will accelerate its research and development efforts to support early establishment of this business.
