A combined heat and power demonstrator plant in the UK has been able to generate food grade carbon dioxide (CO2).
The plant, designed by Ricardo with consortium partners Bluebox Energy and Woodtek Engineering, is fed by sustainable wood waste to supply clean energy, heat and biochar along with CO2, and can capture up to 90% of carbon in the feedstock.
Annual performance figures for a commercial, single-module based on 8,000 hours of operation are 2,600 tonnes of waste woodchip; 540 tonnes of biochar; 2,300 tonnes of food-grade carbon dioxide; 330 MWh of electricity; and 1,200 MWh of heat, providing the potential to capture up to 4,100 tonnes of carbon dioxide equivalent (CO2e).
The consortium is funded by the UK Government through the Net Zero Innovation Portfolio (NZIP) under the Department for Energy Security and Net Zero.
