The company’s technology has demonstrated a cost of capture of under $200 per ton, according to co-founder and Chief Executive Officer Marcus Lima. Heimdal’s approach to grabbing CO2 from the air involves heating quarried limestone, exposing the resulting material to air to absorb the gas, and then heating it again to extract the captured CO2.
