CO2 Storage – The lifeline for fossil fuels? Illustrate your essay with specific examples.
Increasing atmospheric concentrations of carbon dioxide (CO2) is
regarded as one of the main causes of anthropogenic climate change.
This byproduct from combustion of fossil fuels traps reflection of
heat from the Earth back to the Sun, in effect acting as a thermal
greenhouse roof surrounding our planet in the Milky Way. Scientists
have coupled this to a number of potentially devastating
consequences like globally rising sea levels.
The political process to mitigate these threats has come to the
spotlight through a series of UN summits. The aim is to reach
consensus and binding agreements on a cap limiting the amount of
CO2 emitted worldwide. Each nation will have their individual
CO2 storage is an exciting idea to remove carbon dioxide
otherwise headed to the atmosphere from major plants. This paper
studied the principles and how it is being used around the world. A
special focus was put on the different technical methods.
It was found that oxyfuel provides the best reduction in
emissions, in particular as it also diverts nitrogen from the
outlet. It is at present more expensive than post combustion and
therefore used mostly in very big plants. There is hope that this
price can fall as better ways to obtain the necessary purified
oxygen are developed. I expect oxyfuel to be the technology of
choice for the future.
