Review on Bioenergy Storage Systems for Preserving and Improving Feedstock Value

Lynn M Wendt et al. Front Bioeng Biotechnol. .

Abstract

Long-term storage is a necessary unit operation in the biomass feedstock logistics supply chain, enabling biorefineries to run year-round despite daily, monthly, and seasonal variations in feedstock availability. At a minimum, effective storage approaches must preserve biomass. Uncontrolled loss of biomass due to microbial degradation is common when storage conditions are not optimized. This can lead to physical and mechanical challenges with biomass handling, size reduction, preprocessing, and ultimately conversion. This review summarizes the unit operations of dry and wet storage and how they may contribute to preserving or even improving feedstock value for biorefineries.

Keywords: biofuels; biomass; feedstock logistics; long-term storage; recalcitrance.
