全球每年生产70亿吨碱性材料，作为工业活动的产品或副产品。这些材料的水溶解产生高pH溶液，溶解二氧化碳，以固体碳酸盐矿物或溶解的碳酸氢根离子的形式储存碳。我们在这里表明，到2100年，这些材料每年的二氧化碳储存潜力为29亿至85亿吨，并可能在将全球气温变化限制在
7 billion tonnes of alkaline materials are produced globally each year as a product or by-product of industrial activity. The aqueous dissolution of these materials creates high pH solutions that dissolves CO2 to store carbon in the form of solid carbonate minerals or dissolved bicarbonate ions. Here we show that these materials have a carbon dioxide storage potential of 2.9-8.5 billion tonnes per year by 2100, and may contribute a substantial proportion of the negative emissions required to limit global temperature change to
