What’s the market size for concrete hardened with CO2?

From what I’ve read this is a technique to lower the cost of concrete, so the added value would be capped at roughly whatever the price of concrete without CO2 is. There’s also the possible substitute of CO2 derived from other sources with a lower recovery cost, such as sequestration at a plant as you mentioned. How much can be charged for captured CO2 and what’s the market price?

The big difference between plant sequestered CO2 seems to be the need to sweep up and store the CO2 which will be stored across the country. How will the infrastructure for offloading into the tank and delivering the captured CO2 work? How many tanks and how many trucks for moving the liquified CO2?
