Sucking up CO2

Carbon removal by bio-oil injection.

Big Picture

Every year the world produces over 100 gigatons of biomass waste in the form of sawdust, nutshells, corn stover, and other agricultural byproducts. Managing this waste can be expensive, so much of it is burned or left to rot, releasing greenhouse gases into the atmosphere. Capturing the carbon content from just a fraction of this waste could remove billions of tons of CO2 from the atmosphere. 

How it Works

Charm converts waste biomass into bio-oil through fast pyrolysis. That means heating things like plant waste up to 500ºC for a few seconds in an oxygen-free chamber. This process produces bio-oil, a liquid chemical mixture sometimes used today as a fuel. Instead, Charm injects it in underground wells as negative emissions or reforms it to produce green hydrogen as a fuel or industrial chemical.

Unfair Advantage

What sets Charm apart is the focus on bio-oil production rather than seeking to produce a pure stream of CO2. It enables the conversion of cheap inputs like agricultural waste into a carbon-rich bio-oil that can be stored deep underground, leveraging an extensive infrastructure for moving and storing oil itself. This will allow Charm to rapidly scale its supply of carbon removal credits.
