Comparative Lca Of Stand-Alone Power Systems Applied To Remote Cell Towers, Eduardo Olmeda Noguera

Open Access Theses

Remote cell towers need on-site power generation or stand-alone power systems for operation and, traditionally, diesel electric generators have been used as backup power systems in combination with renewable energies. Currently, Polymer Electrolyte Membrane Fuel Cells (PEMFC's) are emerging as substitutes for the diesel electric generator, because of their reliability, high-energy conversion efficiency and zero emissions while operating.^ However, very few studies have compared the environmental impact of these two technologies, especially on remote cell tower applications. As PEMFC's have no emissions while operating, concerns about their environmental impact surge because of the use of rare and high processed materials, …
