While Heirloom declined to disclose the price tag to build the California facility, the company aims to operate at a cost of $100 per ton of carbon removed by 2030
From a Techwire article:
Heirloom estimates that the current cost of the technology ranges from $600 to $1,000 per ton of CO2 removed.
I could not find any article on how much the carbon cost was to run such a facility and move the raw materials to/from it.
Well, they’re using renewable energy to power it. The limestone looks like it’s just constantly recycled, so it would be just the initial transport there. Their output is tanks of compressed carbon dioxide which is sent to a concrete maker, so it really depends on how far away the concrete maker is. There’s a thing called industrial symbiosis, where manufacturers co-locate so that one factory’s waste easily becomes the factory next door’s input.
