Project Description: |
Increased
efficiency of fossil-fuel-fired power plants will have a large impact on CO2
emissions; but additional measures will be needed to reach projected
acceptable atmospheric levels of GHG.
Proposed responses include terrestrial; ocean; and geological carbon
sequestration strategies; as well as biological and chemical approaches. ARC's prior
research project; Reducing Greenhouse Gas Emissions by Direct Mineral
Carbonation; investigated the feasibility of direct mineral carbonation of
olivine and serpentine. The project
made significant progress in showing the technical feasibility of direct
mineral carbonation with olivine and serpentine and determining the
parameters that affect the reaction.
However; questions remain about how to improve reaction kinetics and
extent of reaction. Under conditions
investigated to date; the olivine reaction is slow to initiate; and
serpentine reacts poorly unless it is first heat treated to remove chemically
bound water; both cases present severe economic challenges. The scale of operations required to treat
CO2 emissions from fossil-fuel-fired power plants suggests that the process
might be carried out in-situ in appropriate geological formations. This project complements the previous mineral-carbonation
project by examining concepts that may lead to improved reaction kinetics and
extent of reaction and/or may reduce the importance of time as a process
parameter. |
