BIOCHSTA investigates how large-scale application of biochar—produced by Danish companies from local biomass—affects the long-term stability of stored carbon, soil quality, and groundwater. The project also explores how biochar interacts with different Danish soil types under changing climate conditions, including drought, and assesses the broader environmental and legal aspects of using biochar in agriculture.
In a recent Tech Talk hosted by Energy Cluster Denmark, Professor Henrik I. Petersen (GEUS) presented some of the latest findings—showing that, under the right conditions, biochar can remain stable for millions of years, far longer than many existing models assume. Watch the recording below.
