About Heimdal
Heimdal builds machines that permanently capture and store atmospheric CO2. We are building technology that profitably captures CO2 with this tax credit, right here in the United States. Our first deployment is Bantam, the largest DAC facility in the US with the lowest cost per ton anywhere in the world.
