How big is the storage tank, in terms of volume? To me the one in the video looks too small. I would expect that co2 needs more space than the fuel (since oxygen is added). So a truck needs roughly 100 gallons of fuel for the distance you claim. I would be actually surprised if you can fit the co2 from that into a 400 gallon container (but chemistry is not my strong suit). Any comments?
Edit: I looked up some numbers. 1 gallon produces 9kg of co2, so 80% capture is around 7kg. Co2 has a density of 2g/l at 1 bar (0C). So at modest 200bar you have 0,4kg, so 1 gallon needs 7/0,4=17,5 litre, so 100 gallon 1750 litre=460gallons, and of course a 200 bar compressor.
The tank in the video is just a component of the device overall. The device is 2 cubic meters total, including the storage tank. We'll be storing 600 miles worth of CO2 at a time, or roughly 1800 pounds of CO2.
You are onto something! The video is a proof of concept, so it has the components and performs the adsorption and such but could not capture or store enough for a 600 mi drive cycle.
We are compressing the CO2 significantly, and currently working with tank manufactures to find the right balance between pressure, volume, and weight of the tank (goal is to store ~1800 lb of CO2).
If you want to do math like this for a living we are hiring! :)

Does that sound right to you?
