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
