Summary

Despite the variances among cellulosic sources, there are a variety of technologies for converting biomass into energy. Thermochemical conversion is more aptly used to create heat and electricity due to destruction of chemical bonds. The main thermochemical processes under which biomass can be converted into energy include: combustion, gasification, pyrolysis and hydrothermal liquefaction, while biochemical conversion technology includes anaerobic digestion process. Repowering can involve partial or total replacement of existing infrastructure. Within an integrated biorefinery, heat and electricity are produced through conversion technologies, then used to produce high-value products, recycled to aid conversion, or sold on the commercial market. The main benefit of using these technologies is the reduction of greenhouse gas emissions, but there are still a number of challenges these technologies must overcome.
