Heirloom’s DAC Technology
Heirloom’s innovative Direct Air Capture technology leverages limestone, one of the world’s most abundant minerals, to capture CO2 directly from the atmosphere. The process starts with extracting CO2 from natural limestone, which contains almost 50% CO2. This CO2 is then combined with water to create a material that efficiently absorbs CO2. Heirloom’s technology accelerates this natural process, reducing the time required to absorb CO2 from years to just three days.
Once CO2 is absorbed, it is extracted from the limestone material using a renewable energy-powered kiln. The captured CO2 is then permanently stored underground. This process not only makes DAC more efficient but also brings it closer to being a scalable solution for carbon removal.

With this significant investment, Heirloom is now well-positioned to scale its technology. The company aims to make a major impact on the global fight against climate change.
