UK clean technology company CapChar has launched an integrated biochar and heat recovery system on a livestock farm near Petersfield, Hampshire. The setup processes local woodchip into biochar through pyrolysis, captures the heat for later use with a patent-pending thermal battery, and includes digital measurement, reporting, and verification for carbon removals. About 4 tonnes of woodchip produce 1 tonne of biochar, which represents roughly 2 to 2.5 tonnes of CO2 equivalent, and the company estimates 74% of the carbon could remain in soil for more than 100 years. The project is expected to remove close to 250 tonnes of CO2e, subject to final production data and lifecycle assessment. CapChar is working with Carbon350 on a distributed model where farms and rural businesses can produce biochar locally, use the heat on site, and sell high-integrity carbon credits. The Hampshire installation builds on earlier pilot work in Cornwall and is being used to gather operational data ahead of wider commercial deployment.
