N1 - Funding Information:
Till Strunge has been funded by the German Federal Ministry of Education and Research (BMBF) as part of the project CO2MIN (033RC014) and received a scholarship at Heriot-Watt University. Phil Renforth is funded by the UK’s Greenhouse Gas Removal Programme, supported by the Natural Environment Research Council, the Engineering and Physical Sciences Research Council, the Economic & Social Research Council, and the Department for Business, Energy & Industrial Strategy under grant no. NE/P019943/1. We want to thank the CO2MIN project partners at RWTH Aachen and Heidelberg Cement for their support, in particular we want to dearly thank Mr. Hesam Ostovari and Mr. Dario Kremer for their detailed feedback.

N2 - The cement industry, an industry characterised by low margins, is responsible for approximately 7% of anthropogenic CO2 equivalent (CO2e) 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 CO2e 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 CO2e 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.
