ABSTRACT

There is shortage in electricity supply for household use, which has resulted to prevalent massive subscription to fossil fuel powered electricity generating sets (of various capacities) otherwise known as generators. There exists the need for an adaptable sustainable alternative energy sources to the fossil fuels. The paper presents an Imagineering concept of running a holistic analysis of biogas to electricity conversion system to ascertain adaptability of biogas as alternative fuel source for electricity generation in Nigeria. Backward integration was applied, determining the electricity demand of household, the biogas need, and the capacity of the digester as well as the feedstock, to fulfill this. A typical household in the urban or sub-urban cities in Nigeria; with daily consumption capacity of 20 KWh per day to 30 KWh per day on 6 hours per day supply from the national grid, and 24 hours electricity need, was found to have need of 239kg to 358kg of the organic matter per month and a 12m3 to 18m3 digester size. This shows that the system with the current situation is not sustainable. The paper suggests various means of improving the sustainability and adaptability of the system
