Over the past century humans have extracted and burned hundreds of gigatons of fossil fuels, increasing atmospheric CO₂ from 280 to 415 ppm. Today we’re excited to announce that Charm has developed a new, patent-pending method to help reverse that: bio-oil sequestration.
Bio-oil is produced through fast pyrolysis of waste biomass, then transported to an injection well, prepared for injection, and pumped underground. In the US these injection wells are regulated by the EPA Underground Injection Control Program. The process effectively takes atmospheric CO₂, captures it in biomass, converts the biomass to a liquid similar to crude oil but with half the energy content, and injects it into rock formations that have stored crude oil for hundreds of millions of years.
We’re also excited to announce our first customer for this method: Stripe. Stripe has committed to spending a total of $1m this year across a portfolio of negative emissions projects, and today Stripe has announced that Charm will receive a portion of that to sequester 416 tons CO₂e at $600/ton, using our new bio-oil sequestration method.
While $600/ton CO₂e may seem like a high price for negative carbon emissions, it’s already cheaper than equivalent-scale direct air capture. In the long-run at scale, we believe costs as low as $45/ton CO₂e are achievable.
We plan to complete our first injection in the next few months. Subscribe here for updates. In the interim, you can find answers to frequently asked questions or contact us.

The transition from paper exercise to real operations is never more clear than when a truckload of logs gets dropped off in your yard. When your raw material grows in forests or gets baled in cornfields, and shows up in piles taller than a house, inventory management stops being a spreadsheet exercise and starts being an engineering challenge. Running a diversified supply chain, where your sources are piles of wildfire residue in one location, and bales of corn stover in another, presents a real organizational challenge. At Charm, our business depends on turning irregular biomass residues into stable carbon that is stored underground. As we scale our carbon removal operations, quantifying those piles early, accurately, and repeatedly isn’t just helpful, it’s foundational. That’s why we’ve leveraged AI to measure, store, and evolve our biomass inventory using photogrammetry and computer vision - designed for real yards, real terrain, and real-world variability.

Humanity has emitted hundreds of gigatonnes of CO₂. Now you can put it back underground.
