World-leading technology to reduce carbon dioxide emissions

University of Queensland research into reducing carbon dioxide (CO2) emissions could add $25 billion to Queensland's economy.

Dr Paul Massarotto, Principal Research Fellow at UQ's CO2 program, said the technology had the potential to help sequester most of the current 45 million tonnes per year of CO2 emitted from Queensland's coal-fired power generating plants.

He said the process involves injecting the CO2 into deeper and uneconomic coal seams, sending the carbon back to where it came from.

"The beauty of the process is that as coal adsorbs the CO2 it releases extra coal seam methane, which can be recovered as a clean-burning fuel," Dr Massarotto said.

"The complete cycle could make our coal-fired power plants zero-emissions facilities."

He said by using this technology many large industrial sites in Queensland, and around the world, could reduce atmospheric emissions of CO2 and gain economic benefits as well.

Dr Massarotto said the International Energy Agency had identified Australia as the prime world region for implementing this geological CO2 sequestration technology, particularly at large point source emitters such as coal-fired power plants and big industrial processing plants.

UQ's extensive research program seeks to accelerate technical and environmental capability in deep coal sequestration of CO2, extending to field trials and eventual adoption in Queensland and New South Wales if demonstrated to be viable. Though pilot tested in the USA and Canada, there are still several knowledge gaps being researched by the 14-member UQ team.
