Biomass energy is energy derived from plant life. For practical purposes biomass usually means woody or herbaceous (grassy) crops that can be used directly as fuel; for anaerobic digesting for biogas; or for making liquid fuel.
Wood is available for fuel as logs, chips, briquettes and pellets. Each form has its merits and each requires to be treated differently in terms of handling and combustion. Pellets are manufactured and are comparatively expensive but are consistent in quality, logs are cheap but can be more difficult to handle, chips are usually cheaper than pellets but more expensive than logs and the quality can vary. Wood quality can be affected by moisture content and the species of the tree they come from though pellets are unaffected. These variations in quality affect the performance and selection of the combustion and handling equipment.
Correctly managed, with the establishment of supply chains, biomass is a sustainable fuel source that can both offer a significant reduction in carbon emissions compared with fossil fuels and also provide local economic benefits.
