Emerging Technology Flashcards
What is meant by Carbon Capture and Storage (CSS) ?
Technology designed to prevent carbon dioxide, produced when burning fossil fuels, from entering the atmosphere.
What is the benefit of Carbon Capture and Storage (CSS)?
Capturing the CO2 reduced the impact of the combustion of fossil fuels on climate change by reducing the amount of CO2 in the atmosphere.
How does Carbon Capture and Storage (CSS) reduce the impact of fossil fuel combustion?
CCS reduces the amount of greenhouse gases in the atmosphere
What are the 3 Stages of Carbon Capture and Storage (CSS)
Trapping and separating
Transporting
Storing
(CSS) Describe the process of trapping and separating
Collecting gas emitted from the process and separating the CO2 from the other gases.
This can be done by:
- Post-combustion capture
- Pre-combustion capture
- Oxy-fuel combustion capture
In carbon capture, what does pre-combustion capture and post-combustion capture imply?
These ways are carried out at specific times of combustion process
In carbon capture, does oxy-fuel combustion capture require?
Requires the fossil fuel being used and burnt in oxygen.
(CSS) Describe the process of Transporting
Moving the isolated CO2 (usually in liquid state) to a storage facility in a system of pipes running to an underground space such as a dis-used oil well or under the sea.
Why is the CO2 usually in liquified state when transporting during carbon capture
In the pipelines, CO2 (l) occupies less volume than CO2 (g)
What are the Risks and Hazards of transporting carbon dioxide?
- Leaking pipes
- Increase plant mortality nearby
- Damage to other aspects of ecosystems
- Affect human health
Describe the storage in carbon capture and storage (CSS)
A long term location to place the captured gas
Where is carbon dioxide commonly stored in CSS?
Underground or underwater
Explain the risks and hazards of storing carbon dioxide underground?
Pressure built up can lead to small seismic events
Leaks will affect the ecosystem due to higher concentrations of carbon dioxide in the vacinity
What is geo-engineering?
A range of processes which use our scientific and engineering knowledge to modify our planet’s natural systems.
Why do we need geo-engineering?
Try to counteract the effects of climate change
