要約

Fuel Cell-based Co-generative Heat and Power (FC/CHP) systems are very attractive for stationary energy generation, because they allow co-production of electricity and heat in a decentralized, quiet, efficient, and environmentally-friendly way. So, Enel Ricerca decided to install a natural gas-fuelled polymer electrolyte (PE) FC/CHP pre-commercial prototype, supplied by H-Power, at its experimental area.
The whole PEFC/CHP system has been experimentally analyzed under all possible operating conditions, so that thermodynamic and environmental performances have been evaluated. Using these results, two possible modifications of the PEFC/CHP system configuration to increase its energy conversion efficiency and improve its environmental impact have been highlighted. Then, an energy distribution scenario analysis has been performed. Supposing both a scenario with a large diffusion of the PEFC/CHP systems in the decentralized domestic end-users and a long-term scenario of hydrogen-fed systems connected to fossil fuel derived (joined with CO2 sequestration) hydrogen distribution grids, a global environmental impact comparison between combined and separated generation of heat and power has been executed. This scenario analysis has shown that a wide FC/CHP system diffusion in the decentralized end-users would reap large environmental benefits.
