Bio Coal – green, renewable and sustainable direct biomass replacement of conventional coal.
Bio-fuels are derived from the natural carbon cycle of plants, which absorb carbon from the atmosphere while they grow and normally return carbon dioxide to the atmosphere as they decompose. While they burn, they simply return the carbon they first removed with no change in the atmosphere’s net carbon. Therefore, replacing fossil fuels with bio-fuels prevents the release of extra carbon emissions into the atmosphere.
Biocoal is a solid fuel made from biomass by heating it in an inert atmosphere. The result is either charcoal, or if the process temperature is mild, a product called torrefied wood. Charcoal and torrefied wood also is known as biocioal or green coal.
Biocoal is a much cleaner fuel than fossil coal because it emits significantly less SOx and NOx (sulfur oxides and nitrogen oxides are pollutants that cause acid rain). Moreover, biocoal has energy density close to regular coal (25-28 GJ/ton), making it as efficient as coal.
Leveraging the enormous installed base of current power production assets and invested capital, torrefaction enables an affordable and fast substitution of fossil coal by biomass.
