  • Geological Sequestrationof Carbon Dioxide

  • What is Sequestration? The removal of CO2 from the atmosphereNaturalForestsOceansSoilsArtificialCarbon captureOceanGeologicalMineral

  • Geological SequestrationInjection of captured CO2 deep into the ground.800 metersSupercritical fluidDenser than gasAllows for more storagePotential to remain there

  • HistorySince 1970: petroleum companies use it to retrieve more oil.Since 1930: manufacturers, use it to make products like dry ice.

  • ProsReduces CO2Largest contributor to global climate changeConsCould reactivate faultsEnvironmental effectsBe harmful to humansResearch still in progress

  • Case StudyNorway implemented a $55/ton tax on CO2Norways state oil companySleipner facilityFirst and onlyCost to construct: $80 millionAnnual cost 1% Saves $55 million/year

  • ConclusionStill need more observations and researchReduces CO2, reducing global climate changeFinancially stable business techniqueNot the only solution to global warming but it appears to be a good start
