AbstractThe cement industry, an industry characterised by low margins, is responsible for approximately 7% of anthropogenic CO₂ equivalent (CO_2e) emissions and holds the highest carbon intensity of any industry per unit of revenue. To encourage complete decarbonisation of the cement industry, strategies must be found in which CO_2e emission reductions are incentivised. Here we show through integrated techno-economic modelling that CO₂ mineralisation of silicate minerals, aiming to store CO₂ in solid form, results in CO_2e emission reductions of 8–33% while generating additional profit of up to €32 per tonne of cement. To create positive CO₂ mineralisation business cases two conditions are paramount: the resulting products must be used as a supplementary material in cement blends in the construction industry (e.g., for bridges or buildings) and the storage of CO₂ in minerals must be eligible for emission certificates or similar. Additionally, mineral transport and composition of the product are decisive.
