Abstract
In this paper is study the potential of bioelectricity generation from vinasse biogas, to feed a water electrolyser to obtain biohydrogen. Is analyzed the production capacity of bioelectricity using the vinasse biogas in a internal combustion engine set Caterpillar CG 260-16 (60Hz) model. By the energy analysis of biohydrogen production, and energy efficiency determination of the process is possible the construction of the Sankey Diagram of the process. To study the electrical energy production potential, real production data from a sugar cane plant located in the state of São Paulo are used. The electrolyser used is the HySTAT 600 model, chosen by the minimum electrical power required for its operation. In the next step the cost of biohydrogen production by electrolysis using vinasse biogas from the sugar/alcohol industry of Brazil is determined as a function of payback period, operation hours and annual interest rate. Also, its economic feasibility is studied of the biohydrogen production process. As the conclusion, are demonstrate the efficiency level of bioelectricity generation and biohydrogen production.
