Industrial carbon capture trial
Rio Tinto and Shougang launch industrial carbon-capture trial at Chinese steelworks.
Anonymous
Rio Tinto and China’s Shougang Group have commissioned an industrial-scale carbon-capture trial at Shougang’s Jingtang steelworks, designed to process up to 3,000 cubic meters of blast-furnace gas per hour and capture as much as 10,000 tonnes of carbon dioxide annually. The facility is integrated into existing ironmaking operations and will be used for long-term research and testing, following a smaller installation in 2024 as part of the companies’ 2022 steel-decarbonization partnership. The partners are assessing whether waste heat can lower capture costs and whether captured carbon dioxide can be converted into syngas for reuse in steelmaking; the project’s capture efficiency and share of site emissions addressed have not been disclosed.
Key Points
1
The 2022 partnership also covers low-carbon sintering and optimization of both blast furnaces and basic oxygen furnaces, extending beyond carbon capture.
2
Rio Tinto vice president Ramona Sim described the trial as part of the companies’ 30-year relationship and said carbon capture and utilisation could help reduce emissions from existing blast furnaces as the technology develops.
3
The trial is taking place at Shougang’s Jingtang operations in Hebei province, and Shougang is described as one of the world’s top-10 steel producers.
4
The articles place the trial within a wider regional push: a separate BHP-led consortium is conducting a preliminary feasibility study to identify potential large-scale carbon-capture and storage projects in Asia, with steelmakers including ArcelorMittal, Nippon Steel India, JSW Steel and Hyundai Steel among its participants.
