MELBOURNE, Aug 24 (Reuters) - Australia has awarded Japan's Inpex Corp, France's TotalEnergies and Woodside Energy Group offshore acreage permits for assessing carbon emissions storage as the government pushes to speed up emissions reductions.

While environmental groups say carbon capture and storage (CCS) has yet to work effectively and will prolong the use of fossil fuels, the Labor government sees it as essential to slashing emissions by 2050.

At the same time as announcing the award of the CCS permits, the government also invited bids for new offshore oil and gas exploration acreage, which it said was important for securing energy supplies.

"Australia has the capacity to continue to be an energy export leader, at the same time as developing a domestic offshore carbon capture and storage (CCS) industry," Resources Minister Madeleine King said in a statement.

Inpex, Woodside and TotalEnergies jointly won a permit for an area in the Bonaparte Basin and Woodside won a permit in the Browse Basin, both off northwestern Australia, where Woodside is looking to develop the country's biggest untapped offshore gas prospect but only if it can do so profitably with CCS.

"Australia is ideally placed to become a world leader in this emerging industry, with large, stable offshore geological formations for greenhouse gas storage," King said.

Inpex, with a 53% stake, said it would be the operator of the Bonaparte CCS assessment joint venture.

"Acquiring this permit provides an exciting opportunity to prove up a large-scale carbon storage site in northern Australia, with the potential to become one of the largest CCS projects in the world," Inpex President Director Australia Hitoshi Okawa said in a statement.
