Stiesdal’s technology converts waste biomass from agriculture into biochar and gas
Denmark invests in biomass pyrolysis for carbon removal
Startup aims to store emissions from waste crops as solid biochar
Danish climate technology firm Stiesdal is moving to scale up its Skyclean pyrolysis technology as it eyes opportunities to decarbonise industry, agriculture and transport. The firm has recently secured a DKK124mn ($17.4mn) government grant, which it will use to fund a 20MW project co-located with a bioenergy plant owned by BB Bioenergi in Vra, Denmark. The technology heats waste biomass from agriculture, converting it into inert solid biochar and biogenic gas. The company estimates that for every 40,000t of dry waste biomass, 15,100t of biochar will be produced. Because the CO₂ in the biochar is essentially removed from the atmosphere, the firm says this results in 28,200t of CO₂ emissions
