Techno-economic assessment of the effects of biogas rate fluctuations on industrial applications of solid-oxide fuel cells

Results from Industrial Size Biogas-Fed SOFC Plant (DEMOSOFC Project)

“…If a minimum plant size for biogas production is considered (internal energy generation is crucial for the goal of self-sufficiency), only 5,141 plants (19.1%) are large enough to include anaerobic digestion (with a minimum limit of 20 0 000 P.E.) [3]. The EU WWTP average size correspond, considering a biogas production rate of 15 l biogas/P.E./day, corresponds to a CHP size of 75 kW e (with an electrical efficiency of 53% [4]).…”
