Queensland outlaws carbon storage in Australia's most significant aquifer

Australia's Queensland state will prohibit carbon capture and storage in a giant aquifer that spans much of its area, the state federal government said on Friday, after an outcry from farmers who said such projects could poison their supply of water.

The decision closes one path to decarbonisation in Queensland, which intends to minimize its greenhouse gas emissions by 75% from 2005 levels by 2035 and achieve net no by 2050.

The state had currently this month obstructed a plan by mining giant Glencore to bury melted carbon dioxide caught from a coal-fired power plant in part of the aquifer.

Today is a fantastic day for Queensland, for the environment, for farmers, and for the Great Artesian Basin, state Premier Steven Miles stated in a declaration.

I've listened to Queenslanders, he stated. I think the Excellent Artesian Basin's distinct ecological, agricultural, financial and cultural significance deserves safeguarding.

The basin is a network of aquifers that covers the majority of eastern Australia, supporting farming and neighborhoods.

Greenhouse gas storage activities including carbon capture and storage and boosted oil recovery utilizing a greenhouse gas stream will be permanently forbidden in the basin, the state federal government said.

These activities might be possible in other parts of the state and the government would put together an expert panel to evaluate the security of doing so, it stated.

When obstructing the Glencore task, the state's environment ministry said the buried carbon dioxide might migrate, spreading pollutants consisting of lead and arsenic and triggering irreparable or long-term damage to groundwater.

Glencore blamed the choice, which followed a project by farmers, on misinformation and political opportunism. It said its proposal was safe, targeted an area deep underground with unused, low-grade groundwater and the co2 was incredibly not likely to spread far.

Queensland's orders do not affect other areas that host the basin. Oil firm Santos is building a carbon capture and storage job in part of the basin in South Australia state.
