Pilot Plant Strips C02 From Atmosphere - My Understanding in 30 Minutes

A company called Carbon Engineering has made a pilot plant that is able to capture air and turn the carbon dioxide from the air to pure C02. The pure C02  can then be used in other industrial processes, such as making fuel, or it can be stored deep underground (similar to CCS). The technology uses two processes, an air contractor and a regeneration process. From my understanding the process works in the following way:

• The air contractor is powered using an energy source, however even if this energy source produces waste gases, these can also be taken into the overall process to capture the C02
• The air contractor takes in any atmosphere air and produces a solution which is rich in CO2 by capturing it with a special chemical solution
• The C02 reacts with KOH to make a solution of K2C03 which is taken through to a pellet reactor
• The pellet reactor contains Ca(OH)2 which results in a reaction that created solid CaC03 and regenerates the KOH used at first
•  The regeneration process then produces pure C02 and re-makes the original captured chemical
•  There is a continuous capture of C02  

It is expected that the process will be scaled up to industrial use very soon, which is important as the process claims to remove more C02 than any natural process such as through trees or plants. This process could potentially reduce the effects of climate change, which I find very intriguing.
