					Geological Sequestration
           of
    Carbon Dioxide
            What is Sequestration?
         The removal of CO2 from the atmosphere

   Natural
    – Forests
    – Oceans
    – Soils
   Artificial
    –   Carbon capture
    –   Ocean
    –   Geological
    –   Mineral
        Geological Sequestration

   Injection of captured CO2 deep into the
    ground.
    –   800 meters
    –   Supercritical fluid
    –   Denser than gas
    –   Allows for more storage
    –   Potential to remain there
                    History
   Since 1970:              Since 1930:
    petroleum                 manufacturers, use
    companies use it to       it to make products
    retrieve more oil.        like dry ice.
   Pros                            Cons
    – Reduces CO2                    – Could reactivate
       Largest    contributor         faults
           to global climate             Environmental
           change                         effects
                                         Be harmful to
                                          humans
                                     – Research still in
                                       progress
                    Case Study
   Norway implemented
    a $55/ton tax on
    CO2
    – Norway’s state oil
      company
        Sleipner facility
        First and only

        Cost to construct: $80
         million
        Annual cost 1%

        Saves $55 million/year
            Conclusion
 Stillneed more observations and
  research
 Reduces CO2, reducing global climate
  change
 Financially stable business technique

 Not the only solution to global
  warming but it appears to be a good
  start
