1. Geological Sequestration of Carbon Dioxide

2. What is Sequestration? The removal of CO 2 from the atmosphere  Natural –Forests –Oceans –Soils  Artificial –Carbon capture –Ocean –Geological –Mineral

3. Geological Sequestration  Injection of captured CO 2 deep into the ground. –800 meters –Supercritical fluid –Denser than gas –Allows for more storage –Potential to remain there

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

6.  Pros –Reduces CO 2  Largest contributor to global climate change  Cons –Could reactivate faults  Environmental effects  Be harmful to humans –Research still in progress

8. Case Study  Norway implemented a $55/ton tax on CO 2 –Norway’s state oil company  Sleipner facility  First and only  Cost to construct: $80 million  Annual cost 1%  Saves $55 million/year

10. Conclusion  Still need more observations and research  Reduces CO 2, reducing global climate change  Financially stable business technique  Not the only solution to global warming but it appears to be a good start
