the market for CO2 as a raw commodity is pretty large and growing significantly!

I think your comment on the concrete capped price assumes that the price for producing CO2 does not increase. If current concrete produces CO2 (which it does produce a lot) and CO2 gets taxed, it makes concrete that sequesters CO2 very financially viable even if it cost more than the current concrete market price. Plus I know I would pay more for concrete that sequesters CO2 so maybe that's another competitive advantage that allows it to cost slightly more.

Plants are great and we love and support using our lands more effectively, but there is not enough land to store the CO2 that has been emitted over the last century from fossil fuels, and keep up with the increasing energy demand from population growth as well as developing nations. So plants cannot do this on their own.

There is such a large market for CO2 (and its growing!) that we can find users of the CO2 very near our storage tanks. For example one pilot program we are planning right now has a CO2 concrete producer only 6 miles away! Of course our CO2 hauling trucks will have our device and we will get better and better at leveraging existing infrastructure (pipe lines and trains) to transport CO2 efficiently.

I say put this to work for fizzy drinks. Haul carbon dioxide to fizzy drink company, then pick up fizzy drinks. Profit.
