Abstract
This paper presents a review of the technological, thermodynamic and economic aspects of the electricity generation from biomass. Technologies involved in an integrated system for the production of electricity from biomass usually are the conventional steam cycle, the Organic Rankine Cycle and the Internal Combustion Engines coupled to biomass gasifiers. Collecting up-to-date information allowed estimating the costs and performance of different electricity generation technologies from biomass. To be analyzed, the generation systems were divided according to their power ranges in industrial > 3 MWe, medium scale generation 0,1-3,0 kWe and small-scale generation < 0,1 kWe. Typical energy efficiencies of these cycles are between 8 and 30 %, with the conversion efficiency increasing with size. The investment cost of the technologies, that just reached the commercial stage - including erection - varies between 5.000,00 and 10.700,00 USD/kW. This review paper intends to be a contribution to summarizing the knowledge about using biomass for electricity generation and information needed for energy planning and energy system analysis. No such analyzes were found in the literature reviewed. Another novel contribution of the paper is the presentation of a methodology allowing do determine the power capacity of the generation unit starting from available biomass in ton/h, while defining the electricity generation technology, primary conversion reactors, and biomass pretreatment technology to be used, based on reviewed information from published papers and reports.
