The Transformative Power of Carbon-Negative Energy
CNIL is developing a large-scale energy, biochar and carbon capture and biochar production facility in Lincolnshire — converting wood and woody biomass into a permanent carbon sink while generating clean energy.
A New Class of Infrastructure
Carbon Negative Infrastructure Limited is building the UK's most ambitious biochar production facility. Located in Boston, Lincolnshire, the plant may process up to 137,000 tonnes of biomass waste per year through modern pyrolysis technology and re-use of the existing machinery at the plant.
The process produces three outputs: synthesis gas (syngas), which is converted to steam then electricity , and biochar — a stable, carbon-rich material that locks atmospheric carbon into the soil for centuries, and durable CORC carbon credits.
The Energy and Biochar Process
Feedstock intake
Woodchip, forestry arisings, and clean, green biomass are received, dried, and prepared for processing. Feedstock is sourced from within a 50-mile radius where possible, minimising transport emissions.
High-temperature Pyrolysis
Biomass enters a pyrolysis chamber operating at 600–850°C in a low oxygen environment. This process breaks down organic material into syngas (CO, H₂, CH₄) and a solid carbon residue (biochar).
Syngas energy recovery
Cleaned syngas is combusted generating up to 12 MW of electricity and significant process heat — enough to power the facility and export surplus to the grid to power thoussnds of homes in the UK.
Biochar production and certification
The carbon-rich solid residue is processed into certified biochar meeting European Biochar Certificate (EBC) standards. Each tonne of biochar produced represents approximately 2.5t of CO₂ permanently removed from the atmosphere, depending on feedstock quality.
Soil application and carbon credits
Biochar is supplied to agricultural partners for soil amendment, improving crop yields and water retention. Each tonne generates verified carbon removal credits (CORCs) under internationally recognised standards such as Puro Earth.
Measurable, Permanent Carbon Removal
Unlike nature-based carbon offsets that can be reversed by fire, disease, or land-use change, biochar represents a near-permanent form of carbon sequestration. Once incorporated into soil, the carbon is stable for hundreds to thousands of years.
The CNIL facility will be independently verified and registered under recognised carbon removal standards, generating high-integrity carbon removal credits that meet the growing demand from corporate net-zero commitments.
