Olivine Mineral Proposed as Carbon Capture Solution in Australian Climate Initiative

Australian scientists are exploring the use of olivine, a silicate mineral, to combat climate change through carbon capture. When crushed and spread on land, olivine absorbs atmospheric CO₂ through a chemical process called the Urey reaction, permanently storing it in soil carbonates. Australia's abundant silicate rock deposits and mining expertise position it to potentially lead in this nature-based climate solution. However, current extraction and transportation methods using fossil fuels reduce effectiveness, requiring cleaner energy systems to maximize benefits. Research suggests applying crushed silicate rocks to agricultural lands could remove significant CO₂ volumes while improving soil quality.
