As Callide Oxyfuel demonstration phase draws to a close, the world’s first industrial-scale demonstration of oxyfuel combustion and carbon capture technology has been successfully completed at the Project in Central Queensland.
The $245 million international joint venture project has achieved over 10,000 hours of oxy-combustion and more than 5,500 hours of carbon capture from the coal-fired electricity generation facility at CS Energy’s Callide A Power Station.
One of only a handful of low emission coal projects in the world, the Project is making a significant contribution to the international carbon capture and storage knowledge bank. The results from the Project will be analysed, published and potentially used in the development of future low emission projects the world over.
Callide Oxyfuel’s project director Dr Chris Spero said the international partnership has made a significant global contribution towards finding new ways of producing cleaner and affordable electricity from fossil fuels.
“We successfully tested oxyfuel technology and carbon dioxide capture under ‘live’ power station conditions for more than two years, and our results show it is ready for the next steps toward commercial application,” he said.
The Callide Oxyfuel Project has also helped advance the generation industry’s investigations into the viability of carbon dioxide storage through its collaboration with CO2CRC.
“Carbon dioxide from the Project was transported by road to Victoria and injected underground at CO2CRC’s Otway Project site in South Western Victoria. Building on the large body of work already done by CO2CRC, the injected carbon dioxide was used to evaluate the geochemical and physical behaviour of carbon dioxide within the storage rock.
“Our project has helped create a pathway for the design and construction of larger scale oxy-combustion plants with carbon capture, as both ‘bolt-on’ technology to existing plant or as new-build plant.
“The future for this technology is very exciting,” Dr Spero said.
The project was awarded $63 million from the Australian Government under the Low Emissions Technology Demonstration Fund. The Callide Oxyfuel Project has also received financial support from the Japanese and Queensland governments and technical support from JCOAL.
