Solid and wet biomass fuels are of relatively low energy density, compared with fossil alternatives, and consequently large volumes are typically required to be stored and transported, both into the storage receptacle and from it to the energy conversion equipment.
Factors to consider
Biomass does not generally flow as freely as oil or natural gas.
It will usually absorb moisture if exposed to it.
It may naturally biodegrade in storage through a number of mechanisms, particularly if not absolutely dry. This will lead to loss of energy content and potentially the formation of moulds, the spores of which can be dangerous if inhaled.
Design of the storage facility
The storage of biomass must be well designed and constructed for a number of functions.
It must keep the fuel in good condition, particularly protecting it from moisture.
It must also be possible to deliver the fuel into an appropriate receptacle for transport, and convey it from there to its next destination conveniently and efficiently and requiring the minimum of additional energy input.
