RECOAL AG will produce Negative Emission Coal (NEC) from waste biomass in its own production plants and store NEC in its own permanent underground deposits, called Negative Emission Vault (NEV).​ The RECOAL AG approach is the simplest and, at the same time, the safest and most efficient method of carbon removal to date. RECOAL AG imitates and accelerates what nature did millions of years ago with affordable costs.
