Coolimba Oxy-fuel Project
Aviva Corporation and AES were planning to build a new 2x200 MW oxyfuel-ready power station near Eneabba in the mid west of Western Australia with the potential to capture and store up to 90 per cent of its CO2 emissions, and with plans to phase in up to 2.9 million tonnes a year of CCS – for up to 30 years – as a separate project, when feasible. According to the project website, the company’s investment in the proposals was written off in 2009 and development is now uncertain.
Coolimba could have become one of the first commercial-scale CCS projects in Australia. It is well placed within the region’s energy hub, close to two major gas pipelines and the Perth Basin gas fields. Fuel would have been sourced from the Central West coal deposit 15 kilometres south of Eneabba.
In July 2010, Australia’s Environment Ministry approved the project in part after assessing environmental approval appeals. The Environmental Protection Authority (EPA) had already recommended approval in March, subject to strict conditions.
The Coolimba Power Project was estimated to cost around A$1 billion. Investment was withdrawn in 2009.
The project's future is uncertain due to a reprioritisation of company investment, and is effectively cancelled.

Suitable sites for long-term storage of CO2 still need to be chosen. In 2008, Aviva commissioned the Cooperative Research Centre for Greenhouse Gas Technologies (CO2CRC) to assess potential in the mid west of Western Australia. Initial results of the study have identified the depleted gas reservoirs Beharra Springs, Dongara and Woodada in the Perth Basin as potential storage sites. More research is needed into several deep saline reservoirs.
