In this episode of the podcast, I have talked about Carbon Capture Storage and why it matters.

The steps moving CCS to commercialization rely on making the necessary investments in the technology and involve both the private and public sectors. The four essential elements include:
Absorption:
A liquid sorbent is used to separate the CO2from the flue gas.The sorbent can be regenerated through a stripping or regenerative process by heating and/or depressurization. This process is the most mature method for CO2 separation. Typical sorbent include mono ethanolamine (MEA), diethanolamine (DEA)and potassium carbonate.
Adsorption:
In contrast to absorption processes which use a liquid absorbent, a solid sorbent is used to bind the CO2on its surfaces. Large specific surface area, high selectivity and high regeneration ability are the main criteria for sorbent selection. Typical sorbents include molecular sieves, activated carbon, zeolites, calcium oxides, hydro-talcites and lithium zirconate.
Once CO2 is separated from the rest of the flue gas components it needs to be transported to the storage site or to the facilities for its industrial utilization. Whatever the chosen final fate of CO2,reliable, safe and economically feasible system of transport is a key feature of any CCS project. Depending on the volumes involved a variety of means of transport may be utilized, ranging from road tankers to ships and pipelines. A study related to CCS in the North Sea highlights that CO2transport by ship tanker, using technologies derived from the LPG carriers, is feasible and cost competitive with pipelines with a total cost ranging from 20 to 30 USD/tonne when more than 2MtCO2/year are transported within the distances involved in North Sea storage .

Note: I apologize for the noise coming from the background, I tried my best to cut the noise from the background but it is the best edit I can do. I will cut the entire unwanted noise from my background in the upcoming podcast. I am once again Sorry, I promise it won't happen again.
