Review of the various CO2 mineralization product forms

Abstract

Two experimental modes of operation, a sequence of batch and a continuous one, have demonstrated the technical feasibility of Shell’s proposed slurry-based direct flue gas mineralization concept on the basis of activated serpentine. The base case mineralization concept can be simplified yielding a variety of product forms and significantly reduced CO2 abatement costs. Combined with a positive first assessment of the sustainability of the various mineralization product forms, all mineralization concepts deserve to be further investigated. To optimally take advantage of integration opportunities so as avoid parasitic CO2 emissions and minimize cost, this should be done over the complete technology chain.
