Green Cement Decarbonisation Project
Green Cement Decarbonisation Project
As part of an overall decarbonisation plan for its Port Augusta (South Australia) cement manufacture facility, the Hallett Group would use renewables-based hydrogen to power the heating and drying of up to one million tonnes a year of lower-carbon substitutes for clinker.

Project description
In July 2023, the South Australian Government, the Hallett Group and Korean companies Elecseed and Korea Hydro and Nuclear Power (KHNP) signed a Statement of Cooperation in support of progressing development of a green cement processing project being undertaken by the Hallett Group in Port Augusta, South Australia.
As part of a broader cement decarbonisation plan by the Hallett Group, Elecseed-KHNP would build a 12 MW solar farm, battery energy storage system, and 6 MW hydrogen electrolysis plant at Hallett’s Port Augusta facility to power the heating and drying of up to one million tonnes a year of lower-carbon substitutes for clinker. These substitutes would include fly ash from the former Playford B and Northern Power Stations in Port Augusta and slag from Nyrstar’s Port Pirie operation to be made into green cement.
The Hallett Port Augusta facility uses circa 15 million litres of LPG per annum. The hydrogen produced by the proposed 6 MW electrolyser plant would supplant/displace around 20% of that volume.
The feasibility study stage of the project is completed, which the project aiming to progress to the FEED stage.
Construction on the project is expected to start in the first half of 2026.
