Australian independent Santos will deliver about 20 PJ/yr (534mn m³/yr) to Whyalla steelworks under a 10-year binding term sheet signed with the South Australian (SA) state government.
The total of 200PJ of gas will supply the 1.2mn t/yr Whyalla steelworks after it transitions into a low-emissions iron facility, subject to a gas supply agreement being signed by 30 June, Santos said on 20 February. Deliveries will start from 1 March 2030.
Delivered ex-Moomba using indexed pricing with a prepayment structure, the deal will coincide with the expiry of Santos' Horizon contract with the 7.8mn t/yr Gladstone LNG joint venture that began in 2016.
Santos' gas will enable Whyalla to deploy direct reduced iron technology to process magnetite ore into low-carbon iron, chief executive Kevin Gallagher said on 20 February, cutting emissions by about 50pc compared to the former coal-fired blast furnace operations.
The steelworks were forced into administration on 19 February 2025 after SA's government passed laws to remove control of the plant from UK-based GFG Alliance. Australian steelmaker BlueScope is leading a consortium hoping to acquire the works, while the aid of more than A$2.5bn ($1.76bn) in subsidies is aimed at moving the works towards a low-emissions facility.
The 20 PJ/yr Whyalla will draw on is about 30pc of Santos' current gas production from the Cooper basin, the Adelaide-based firm said.
SA's Labor government previously planned to build a green hydrogen sector based at Whyalla but last year abandoned plans for a 250MW electrolyser and 200MW hydrogen-fired power station and instead redirected unspent funds to saving the steelworks.
Australian think-tank Climate Energy Finance has been sceptical of the gas-led steel output strategy backed by the federal and state governments, due to Australia's uncompetitive domestic gas prices, it said.
