Sucking up CO2
HQ: San Francisco, CA
Carbon removal by bio-oil injection.
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.
What sets them apart from other carbon removal efforts is the focus on bio-oil production rather than seeking to produce a pure stream of CO2. It enables the conversion of cheap inputs such as waste into high-value products like carbon removals, while leveraging an extensive built infrastructure for moving and storing bio-oil. This will allow Charm to rapidly scale their supply of carbon removals.
