JERUSALEM ARTICHOKE (HELIANTHUS TUBEROSUS L.) AS ENERGY RAW MATERIAL
Keywords:Jerusalem artichoke, energy efficiency, heating efficiency, cultivars, biogas, bioethanol
Jerusalem artichoke is suitable for use in biorefineries due to the very high biomass production and low soil, climate and cultivation requirements. Tubers of this species can be used for the production of methane fermentation or bioethanol. The aboveground part can be used for the production of biomethane, as well as in the direct combustion process or for the production of briquettes and pellets. Of the cultivars tested, Albik and Violet de Rennes proved to be the most useful for energy purposes. An important advantage of Jerusalem artichoke is its resistance to adverse climatic conditions (drought, frost), resistance to diseases and pests and the possibility of self-renewal.
