Stripe purchased 416 tons CO₂e in carbon removal from Charm in May 2020, as our very first customer. That carbon is now permanently sequestered in geological storage.

    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 typically EPA Class I or Class V salt caverns. 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. In the coming months we plan to publish a white paper documenting this new method in detail.

    Charm had a major milestone recently - the company turned 2 years old! More than ever, the team is driven to return the atmosphere to 280ppm CO2, and to do so profitably. We have been working hard designing, building and testing a gasifier that produces cost-competitive industrial hydrogen from biomass. (Did you know hydrogen is an existing $150B/year market and is responsible for 3% of global CO2 emissions?)

    There are many challenges associated with gasification, especially when it comes to gasification of grasses, which are preferable for their high yield and low cost per dry ton. The biggest challenges are ash slagging, acid gas removal, heat transfer into the grass, optimal moisture content, ash disposal, and a very long list of other fascinating puzzles… (we’re hiring!) but today we’re going to talk about one challenge that seemed extremely easy at first glance: how do you load grass into the gasifier?

Put oil back underground

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