Rio Tinto after-hours price dips 0.21%, carbon capture trial starts at Shougang steel plant

Rio Tinto's stock traded at EUR 82.73 after-hours on September 29, 2026, down 0.21% from the prior close of EUR 82.90. The modest move comes alongside news that the miner and Shougang Group have commissioned an industrial-scale carbon capture facility at Shougang's Jingtang operations in China. The trial can process up to 3,000 cubic meters of blast-furnace gas per hour and capture up to 10,000 tonnes of CO2 per year, with plans to convert captured CO2 into syngas for recycling in steelmaking. For investors tracking decarbonization in heavy industry, this trial is a concrete step toward cutting emissions from steel production, which accounts for a significant share of global CO2 output. The integration into Shougang's existing ironmaking system means the project is not just a lab experiment but a real-world test of carbon capture at scale. While the stock move is negligible, the carbon capture development could have longer-term implications for Rio Tinto's climate strategy and its position in low-carbon steel supply chains.
