 Basically the mass part has shrunk more than the energy part, and the consequence is that the calorific value of torrefied biomass increases significantly, to the extent that it can compete with energy dense coals used for electricity generation (steam/thermal coals).Vaclav Smil states that the energy density of the most common steam coals today is 22–26 GJ/t.The higher energy density means lower transport costs, and a decrease in transport-related GHG emittance.
