Fig. 4: Costs for CO2 sequestration via enhanced benthic weathering.

From: Calcite is an efficient and low-cost material to enhance benthic weathering in shelf sediments of the Baltic Sea

Fig. 4

Mean costs including production, comminution, transport, and spreading per tonne of sequestered CO2 for dunite (a) and calcite (b) for a 30-year application period. Color codes indicate the annual addition of material. Line width indicates the geometrical surface (olivine) and the corresponding BET surface (calcite), respectively. Note different range of x-axis in panels a and b.
