biochar

Carbon from the land, locked away for geological timeframes

what is biochar

Biochar is a carbon-rich solid produced from the pyrolysis of organic material. Made from recently grown biomass rather than fossil carbon, it has the potential to sequester carbon for geological timeframes.

From willow to stable char

A continuous, high temperature process turns field-grown biomass into a consistent, highly stable biochar.

01

Biomass

Willow is harvested and chipped directly in the field. The woodchip is then actively dried to a low moisture content.

02

Pyrolysis

The woodchip is fed into a high temperature pyrolysis plant, which breaks the biomass down through thermal decomposition.

Biochar

The Reverse Coal approach pumps this stable char into concentrated deposits underground, in optimised conditions, for long-term, easily verifiable carbon sequestration.

Production is not the end of the process

Storage is only achieved once biochar is held in a verifiable, stable and contained state for an indefinite period. Our solution combines proven experience from construction, mining and wastewater treatment, and applies it to carbon storage.

By burying the biochar in our patent-pending storage solution, we achieve long-term, stable carbon sequestration. It is one of the most concentrated and most easily verifiable of all carbon mass-storage solutions, storing up to 45,408t CO₂e per hectare.

compared to field application, contained storage is

  • More stable
  • More secure
  • Lower in transport costs and emissions
  • Far easier and cheaper to monitor and verify
Verifiable at any time

Long-term validation can be carried out at any point in the future by core-sampling the repository with a small diameter borehole rig.

applications

A consistent biochar for a variety of industries

Beyond permanent storage, our biochar is being investigated as a low-carbon replacement for fossil carbon in industry.

Low-carbon steelmaking

We are working with British Steel to investigate biochar as a substitute for coking coal, replacing fossil carbon with carbon from recently grown biomass.

Agriculture & soils

Biochar's porous structure makes it a candidate soil amendment, and we are exploring its agronomic value alongside industrial uses.
