Study Notes
Carbon Capture and Storage (CCS) in the Context of Net Zero Scenarios
- Net zero scenario aims to limit global temperature rise to 1.5 °C in 2100 without overshoot
- In the net zero scenario, negative emissions compensate for remaining positive emissions
- Carbon Capture and Storage (CCS) contributes about 15% of total CO2 emissions reduction
- CCS aims to ramp up by a factor of ca. 200 by 2050, from 40 million tonnes in 2020 to 5000-17,000 million tonnes in 2050
- Examples of CCS application include natural gas processing in Barents Sea and power generation in Boundary Dam, Canada
- CCS technology reduces greenhouse gas emissions by about 1 MtCO2 per year
- The retrofitted CCS plant is less efficient than a conventional coal plant, with a 20% reduction in energy production
- CCS system components have matured since 2005, as seen in the examples of Snøhvit and Boundary Dam
- CO2 storage options include ocean storage, geological storage, and enhanced oil recovery
- The behavior of CO2 in water varies based on depth and temperature, influencing its phase and dissolution rate
- Marine sequestration, such as dissolution and lake type storage, is part of the CCS discussion
- However, marine sequestration is not considered a long-term solution due to its potential detrimental impact on marine life and the carbon cycle
