This is an interesting idea - great to see people trying out new innovative ideas. I would have a couple questions:
1. How much energy is required to extract and regenerated the adsorbent?
2. How much energy to store CO2 and how much space on-site?
(First two questions are trying to discern if it is truly a net negative product or if the remainder of the process diminish the carbon balance significantly)
3. How much are you anticipating selling CO2 and what is the level of purity (we use it for one of input gases at our company)?
4. What is the reload time for the trucks CO2 wise - and how much of an operational hurdle is the implementation/execution? Truck fleets are notorious for not wanting to change their systems, especially for new untested tech. (It is a thin margin business - risk tolerance is low)
