Abstract

The potential for carbon dioxide (CO₂) sequestration via engineered chemical sinks is investigated using a three dimensional chemical transport model (CTM). Meteorological and chemical constraints for flat or vertical systems that would absorb CO₂ from the atmosphere, as well as an example chemical system of calcium hydroxide (Ca(OH)₂) proposed by Elliott et al. [Compensation of atmospheric CO₂ buildup through engineered chemical sinkage, Geophys. Res. Lett. 28 (2001) 1235] are reviewed. The CTM examines land based deposition sinks, with 4° × 5° latitude/longitude resolution at various locations, and deposition velocities (v). A maximum uptake of ∼20 Gton (10¹⁵ g) Cyr^-1 is attainable with v ≥ 5 cms^-1 at a mid-latitude site. The atmospheric increase of CO₂ (3 Gtonyr^-1) can be balanced by an engineered sink with an area of no more than 75, 000 km² at v of 1 cms^-1. By building the sink upwards or splitting this area into narrow elements can reduce the active area by more than an order of magnitude as discussed in Dubey et al.
