Our synthetic limestone will be on par with mined limestone. At scale when accounting for the higher calcium content per tonne and value of carbon we expect to be cheaper even than mined limestone. You hit the nail on the head there. The most important cost factor is energy. We're looking at <3MWh/tonne of CO2 removed. Somewhat higher than some competing DAC companies that claim 1.5-2.5MWh. But these guys have the added cost of finding permanent storage of their gaseous CO2. Cost estimates for this, at scale, are as high as $100/tonne
