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.

Nature's carbon capture

Cellulosic biomass already captures 100+ Gt CO₂/year. We collect it and put it through a process called fast pyrolysis.

The ideal injectant

Charm's fast pyrolyzers break down biomass into bio-oil, a liquid rich in carbon but low in energy content.

Removed for millennia

Charm prepares the bio-oil and injects it into EPA-regulated injection wells, where the bio-oil sinks and solidifies in place for permanent storage.
