Carbon capture and storage
“Could we fight climate change by taking CO2 out of the atmosphere and putting it into the ground?”
It is a well-known fact that there is an overabundance of carbon dioxide in the atmosphere as a result of human activity. So are there any creative ways in which we could reduce this amount? Well, This, how about if we were to take the carbon dioxide during an energy generation process, and then funnel it into the ground? This seems like a good (yet crazy) concept, but as engineers, we can’t just make ideas, we have to implement them as well. The first step is to capture the CO2 during energy generation. This can be accomplished through one of two methods, post-combustion (which takes in the extra flue gas released during the burning of fossil fuels and uses a filter to separate out the CO2) and pre-combustion (which traps the CO2 gas before it is burned). This gas will then be transported through a pipe towards a deep rock formation, where it will finally be ejected and stored for a longer period of time. Carbon capture and storage has the potential to save much CO2 from entering the atmosphere (upwards of 14% of energy-related CO2 reductions by 2050). A stalwart example of a Carbon capture and storage plant is the Canadian Boundary Dam plant, which has the potential to save up to 90% of CO2 related emissions.
