Study Notes
Geol 40310: Fossil Fuels and CCS Module Overview
- Carbon Capture and Storage (CCS) contributes about 15% of total CO2 emissions reduction in the "Net Zero by 2050" scenario according to the IEA.
- The IEA net-zero scenario predicts an annual CO2 capture and storage of 5 – 17 Gt CO2 across the total energy system by 2050.
- Subsurface Sequestration (Geosequestration) involves utilizing depleted oil/gas fields, unminable coal seams, enhanced oil recovery, saline aquifers, and mineral sequestration for CO2 storage.
- The Weyburn oilfield is sequestering 2 million tonnes of CO2 a year, with a total storage capacity of approximately 55 Mt CO2.
- Over 70% of CO2 used in CO2 EOR projects in the USA comes from natural sources such as natural CO2 reservoirs and industrial CO2 sources.
- The Sleipner CO2 Storage Project has been sequestering 1 million tonnes of CO2 per year in the Utsira sandstone since 1996.
- In 2022, approximately 43 million tonnes of CO2 were sequestered, mainly as part of Enhanced Oil Recovery activities.
- The Hellisheidi geothermal plant in Iceland mineralizes CO2 as carbonates within two years and has captured 12,000 tonnes CO2/year, around 30% of emissions.
- The projected CO2 capture and storage is expected to increase from 40 million tonnes in 2020 to 7,500 million tonnes in 2050, according to historical vs. IEA Net Zero Scenario analysis.
- The module assessment for the course includes a two-hour MCQ examination and continual assessment based on practicals and presentations.
- The module structure involves geology and reservoir engineering practicals, poster presentations, and seminar presentations, with a two-hour MCQ exam constituting 50% of the assessment.
- The examination for GEOL 40310 is scheduled for Friday 15th December 2023, and a sample paper is provided for preparation.
