Molten carbonate fuel cell as resource to stimulate the energetic exploitation of the biogas: Analysis multicriteria applied to a real case

Research output: Contribution to conferencePaper

Abstract

The goal of the study is to show the validity of integrating an MCFC with anaerobic digester gas (biogas), thanks to the related advantages, in terms of: · Environmental benefits · Reduction of the dependence from fuels fossils · Economic revenue · Social benefits Wastewater treatment plants (WWTPs) and manure plants, operating with anaerobic digesters produce a methane-rich gas as a by-product of the process. In most of the cases, this gas is released into the atmosphere, thus increasing the greenhouse effect, due to the presence of methane. At the same time, the methane content makes the biogas an interesting source of energy. An efficient energy recovery presents the dual benefits of reducing greenhouse gas emissions and of producing a usable form of energy (typically electric current or heat), using a renewable source of energy, thus diminishing fossil fuel consumption. For WWTPs, the goal of the study is to investigate the Italian situation, in terms of: number of existing plants, served equivalent inhabitants, typologies of treatment, etc. This is achieved through a detailed analysis of Italian potentialities of biogas exploitation, by estimating the electric and thermal energy producible, and the avoided CO2 emissions. For manure plants, the study considers the Italian situation in terms of operating plants. The Italian potentialities for biogas exploitation, is conducted comparing three different types of energy conversion systems for combined heat and power production: reciprocating engines, gas turbines, and molten carbonate fuel cells. In the second part of the study, the manure-based plant of Marsciano-Perugia (Italy) is analyzed. Using in a techno-economical analysis and a multicriteria analysis, the three technologies have been compared. Results show that the environmental and social benefits of fuel cells will be available for such applications as soon as the production costs make them competitive with the other traditional technologies.
