“Callide Oxyfuel Combustion Project” turns out successfully

200,000-300,000 tons (approximate estimates) of oxygen were utilized for about 3 years

In the middle of December, 2012 at the Callide A Power Station, a coal-fired facility, located in a suburb of Biloela, in the Shire of Banana, Central Queensland, Australia, the demonstration operation commenced related to the world’s first CO2 liquefaction and capture based on oxyfuel combustion process at an actually operating thermal power station. At the beginning of March of this year the targeted 10,000 hours of oxyfuel combustion operation had been reached. In addition along with this, the demonstration operations of the CO2 liquefaction and capture facility were also conducted, lasting over 5,500 hours. The CO2 captured at the power station was transported to the state of Victoria and trials were carried out whereby the CO2 was injected underground. These demonstration operations, spanning 2 years, turned out successfully. Questions arise such as how much oxygen was used, what was the carbon dioxide used for after capture, and how will the success of demonstration operations be made use of in the future. We conducted interviews at IHI which came up with the idea of the “Oxyfuel Combustion Process”, the core technology of the demonstration project, and participated in the development of the technology.
