Abstract

Examining the dissolution behavior of solid mineral phases for open ocean alkalinity enhancement scenarios with laboratory-based experiments was basically impractical. The general occurrence of secondary mineral precipitation during dissolution experiments led to a shift of focus towards the stability of alkalinity and the description of the observed runaway precipitation processes. Based on detailed examinations of the triggering factors for the observed precipitation, results from the stability experiments derived upper feasible limits for the implementation of open world OAE application scenarios.
