Abstract:
As fossil fuels use contin
ues to grow, the climatic and environmental effects associated with increa
sing anthropogenic CO2 emissions are of increasing concern. A potentially v
iable alternative is carbon dioxide sequestration. Several approaches are b
eing considered, including geological, ocean and terrestrial sequestratio
n, as well as converting CO2 into useful materials.
In this talk, the d
ilemma scale-cost-permanence of CO2 mitigation shall be discussed through c
omparison of different sequestration approaches. Major focus shall be givento mineral carbonation processes which make the essence of both mineral (a
bove-ground) and geological (under-ground) sequestration as well as a numbe
r of novel CO2 utilization technologies. Three examples of CO2 utilizationstechnologies shall be discussed: (i) enhanced geothermal systems for renew
able energy; (ii) ground consolidation in unstable soils under existing bu
ildings and for new construction; (iii) development of novel and cost effe
ctive concrete products as building materials. Finally, use of the powerfu
l synchrotron in situ X-ray studies of mineral carbonation processes under
extreme conditions shall be demonstrated.
