Australia’s Queensland bans CCS in Great Artesian Basin

Australia's Queensland state government announced today it will ban carbon capture and storage (CCS) in its portion of the Great Artesian Basin.

Greenhouse gas (GHG) storage activities, including CCS projects, will be permanently prohibited in the basin as the government looks to protect its water resources, Queensland premier Steven Miles said on 31 May. The ban, which will be legislated, also includes enhanced oil or petroleum recovery activities that use a greenhouse gas stream.

Activities involving GHG storage or the injection of GHG streams into underground formations may be able to continue in other parts of the state, subject to existing assessment and approval processes. The government will appoint an expert panel to review projects outside the Great Artesian Basin, which will report back in 2025.

The Great Artesian Basin is Australia's largest groundwater aquifer. It is made up of several sedimentary basins spanning over 1.7mn m² across Queensland, the Northern Territory, South Australia and New South Wales. Water extracted from the basin is used for agriculture, irrigation and stock watering, as well as for industry and household supply in over 80 Queensland towns, according to the government.

Queensland's Department of Environment, Science and Innovation last week rejected the environmental impact statement for commodities producer and trading firm Glencore's CTSCo Surat Basin CCS project, which aimed to demonstrate carbon capture from a coal-fired power station and the permanent storage of CO2. The project was unsuitable to proceed because of the potential impact on groundwater resources in the Great Artesian Basin, the department said.

The CCS ban follows the state's decision late last year to ban unconventional oil and gas extraction in its portion of the Lake Eyre basin to protect inland waterways, as well as conventional production alongside rivers and on floodplains.
