Put oil back underground

Humanity has emitted hundreds of gigatons of CO₂.
Put it back underground with Charm.


Charm collects agricultural residues after the crop has been harvested


Charm builds pyrolyzers to convert biomass into bio-oil in a self-sustaining reaction


Charm's carbon-rich bio-oil is transported to the injection well site


Charm pumps the bio-oil underground where it sinks and solidifies in place

The best of nature and tech

Charm uses plants to capture CO₂ from the atmosphere. We convert biomass into a stable, carbon-rich liquid and then pump it deep underground. This removes CO₂ permanently from the atmosphere, out of reach of wildfires, soil erosion and land use change.
