Mühlbauer et al. (2024): Techno-economic insights and deployment prospects of permanent carbon dioxide sequestration in solid carbonates

An in-depth techno-economic analysis of differentiated sequestration options for carbon dioxide (CO₂) in solid carbonates is not yet available, as direct air capture-based mineralisation is usually aggregated in direct air capture and carbon sequestration. This research gap is closed by studying mineralisation as a key carbon dioxide removal (CDR) option to sequester atmospheric CO₂ permanently, based on available literature. The most frequently discussed routes for mineralisation, i.e., in situ, ex situ mineralisation, and enhanced rock weathering, are examined. The deployment potentials of these options are determined globally for nine major regions.
