A techno-economic assessment for replacement of conventional fossil fuel based technologies in animal farms with biogas fueled CHP units

In this paper, a case study applied to an animal farm in Iran, covering both technical and economic aspects of biogas production using manure from livestock to replace fossil fuel used for heat and electricity generation is presented. The mentioned farm has 3058 dairy cows. Biogas production followed by small-scale combined heat and power (CHP) units based on a new dual fuel internal combustion engine (ICE) have replaced conventional technology...
