The emission of the biogas to the atmosphere may contribute to the greenhouse effect. A solution to this problem would be the development of low-cost and high efficience processes for converting biogas into energy and higher value-added products. An efficient technology for the use of biogas for electricity generation would be its use in the production of H2 for the Proton Exchange Membrane fuel cells.
The UniSim Software has been used for the simulation of the production of H2 from the effluent, which has the installed capacity for the anual production of 70.000.000 m³. In this approach, the biogas is converted to syngas in a reformer, followed by steps of hydrogen purification: Water Gas Shift and Pressure Swing Absorption.
The use of biogas increases energy efficiency, helping reach the use of resources in a sustainable way, without harming the economic growth. The use of these efficiency tecnology can generate positive impacts on the environment, public health and economy. Studies estimate the possibility of having an installed capacity of generation of 311 MW of energy, which could supply a population of 5,6 millions of habitants.
