Critical Evaluation of Carbon Capture Technology and CO2 Sequestration
"Carbon Capture and Storage is also known as Carbon Capture and
Sequestration (CCS). CCS technology captures carbon dioxide (CO2)
from different CO2 emissions sources such as power plant and heavy
industries. It is then transported by carriers or pipelines to different sites
where it is injected and stored one to two kilometres deep inside the earths
crust. This storing of CO2 away from earths atmosphere is known as
sequestration.
CO2 can be sequestrated in various forms such as in geological
formation, ocean and other industrial uses. In geological sequestration,
CO2 can be stored into saline formation, depleted oil or gas fields and
methane coal bed. Geological sequestration process is well understood
and on commercial phase. Geological formation of CO2 was started in
1972 in the form of 'Enhanced Oil Recovery' (EOR) and till now there is
no major leakage. CO2 is sealed by natural non porous cap layers of rocks
and monitored by experts to ensure there is no leakage or have an adverse
impact on either public or environment.
One of the major problems for this technology is its cost. Capturing CO2
from the source is the most expensive part. Transporting the CO2 through
a pipeline is the least expensive and injecting it deep into the earth is more
expensive than transporting it. Research and Development programs are
running worldwide to develop improved and lower-cost technologies for CO2 capture.
Many organisations believe that CCS is the best technology to cut CO2
while other believes that CO2 is the waste of time and investment. But
according to author, CCS is the only option to cut the global emissions of
CO2 and other sources like renewable are good but will not be enough to
cut emissions in this industrial era.
This project is 'research based' on storing CO2 away from atmospheres
and saving the world form global warming. The idea of this project came from
my tutor. This innovative technology has the potential to save the atmosphere
from global warming. There are some barriers but these can be solved as the
technology progresses."
