Heimdal

Heimdal builds machines that permanently capture and store atmospheric CO2. Congress has passed legislation (IRA) guaranteeing a price of $180/tCO2 removed via Direct Air Capture until 2032. We are building technology that profitably captures CO2 with this tax credit, right here in the United States.

We use abundant minerals, in a looping process, and existing industrial equipment to capture CO2. Our process starts with carbonation of an abundant sorbent. Over a short period of time, through passive contacting with atmospheric air, the material is carbonated, whereafter the captured CO2 is stripped and captured by heating the material to high temperatures. CO2 off-gas is captured and stored geologically, permanently.
