Abstract
The Ph.D work, funded within the Bilateral Agreement Confindustria-National Research Council and carried out in collaboration with the University of Naples “Federico II”, the National Research Council – Istituto di Scienze e Tecnologie per l'Energia e la Mobilità Sostenibili (CNR-STEMS) and the company Costruzioni Motori Diesel (CMD) SpA, intends to give a tangible contribution to improving the performance of a micro-cogeneration plant, the CMD ECO20x. After an initial phase of literature review, a fully analysis of the CMD system consisting of a downdraft gasifier coupled with an internal combustion engine (ICE) was exploited, both through the experimental and the numerical approach. The numerical simulation and the multi-objective optimization provide useful information both in the m-CHP design and verification phase. The experimental activity includes the evaluation of syngas and pollutant emissions composition, ICE in-cylinder pressure and the main energy output measurements in a real environment, the municipal waste management centre of Mugnano (NA), in the Southern Italy. Lastly, a numerical study on the m-CHP integration with photovoltaic (PV) solar energy and hydrogen storage, possible thanks to the collaboration with Mälardalen University (Sweden), is made to understand the possibility of providing energy to e-car charging stations in the respect of constraints of compactness, high quality service and ultra-low environmental impact. These results give important information for the on-going project “Borgo 4.0” (2020-on going), funded by POR CAMPANIA FESR 2014-2020, in the creation of a totally innovative and 100% renewable charging infrastructure.
