This appears to me like an elaborate "carbon laundering" scheme?
Producing concrete involves decomposing limestone into calcium oxide and CO2, which is done in a furnace powered by fossil fuels and then just released into the atmosphere. Concrete cures by capturing some of that CO2 again.
This plant takes more limestone, decomposes it using "renewable energy" (i.e power that could have been used to displace non-renewable sources, but isn't), but stores the CO2 in a tank, which is then just put back into concrete. Concrete that would have naturally slightly offset itself anyway?
The net effect is surely just a bit worse than nothing?

But ultimately it doesn't meaningfully reduce the amount of carbon being produced as the costs are just passed onto the customers of those carbon producers to maintain profitability.
