Pelletizing wood is a convenient way to increase its energy density and to provide the consumer with a more convenient solid fuel than split wood. The wood is pressed through a die under pressure at moderate temperatures to produce the pellets.
Wood pellets are an attractive fuel, but continued research is needed to increase their energy density and to be able to produce them from a wider variety of biomass substrates. As wood pellets represent a densified biomass that has been pre-processed, we are interested in their use as a substrate to produce biochars and/or syngas. It is possible that pelletized wood would solve many of the problems for both these products as the substrate is more homogeneous and my have better controlled thermo-chemistry.
SERC’s partners are involved with numerous research projects concerning wood pellet technology and capacity. To learn more, please contact SERC.
