[Rio Tinto commissions carbon capture pilot at Shougang Jingtang steel base]
Rio Tinto has commissioned a pilot carbon capture unit at Shougang Group's Jingtang steel base in China, capturing CO2 directly from blast furnace gas. It can treat up to 3,000 cubic metres of blast furnace gas per hour, targeting up to 10,000 tonnes of CO2 a year in the trial phase. The start-up marks a milestone under a 2022 MoU to develop low-carbon technologies across ironmaking and steelmaking. Blast furnaces are primary steelmaking's biggest emissions source, so point-source capture is a transitional option while DRI and green hydrogen scale up. The trial will produce data on solvent performance, energy use and gas pre-treatment, helping assess commercial CCUS retrofits across China's steel sector. Miners facing Scope 3 pressure see direct trials with steelmakers as key to protecting long-term high-grade iron ore demand.
