Charm Industrial

Carbon Removal with long-lived storage
Bio-oil sequestration
Price (GBP per tonne CO2e)


Converts waste biomass into high-carbon fast pyrolysis bio-oil for stable long term storage or for use as fuel.

About this project

Bio-oil is produced through a process called “fast pyrolysis” where biomass like wood, corn stover, rice straw, or almond shells is heated up to about 500°C in a few seconds without any oxygen present. This process produces a liquid mixture called bio-oil and a solid mixture of ash (like in a fireplace). This bio-oil has high carbon content and is injectable into the same deep underground rock formations that stored crude oil for hundreds of millions of years.

Charm converts waste biomass into fast pyrolysis bio-oil. They then inject bio-oil deep underground as negative emissions, or reform it to produce green hydrogen as a fuel and industrial chemical.

Charm's process for underground bio-oil injection is patent-pending.

Key benefits

  • Very strong credentials (see criteria assessment)
  • Currently an expensive option but viable that price will decrease with scale
  • Bio-oil sequestration is a key technology for future and early support is likely to help with R&D and technology adoption


Proven causality

Very Strong. Charm Industrial takes waste biomass (that would otherwise decompose and release CO₂, and other greenhouse gasses, back into the atmosphere), converts them into a low energy bio-oil, and sequesters it. This is a direct causal relationship and can be considered carbon removal because the process of new crops growing each year takes CO₂ out of the atmosphere. All emissions that occur from the pyrolysis, transportation and injection process are also accounted for.
