Abstract [en]

Access to electricity, clean drinking water andclean cooking gas services are genuine needs of the rural poor in order to improvetheir living conditions. One can think of addressing these needs individually orinstead use an integrated approach. Looking for solutions using a holisticapproach should always have a better impact. A small scale and distributedbiogas based poly generation system could be an effective solution to bringsustainable development to remote and rural areas of Bangladesh. Biogasdigesters are a popular and promising rural energy technology and the integrationof biogas production with power generation and water purification is aninnovative approach. This paper discusses such an integrated poly generationsystem and analyzes the techno-economic performance of the scheme for meetingthe demand of electricity, cooking energy and safe drinking water of 30households in a rural village of Bangladesh. The mass flows and energy balance,life cycle cost (levelized cost) of producing electricity, cooking gas and safedrinking water as well as the payback period of such a poly generation system wereestimated. In this study, it has been found that this poly generation system ismuch more competitive and promising than other available technologies whenattempting to solve the energy and arsenic-related problems in Bangladesh. Thedeterminant factors influencing the performance of the system and their impacton the cost have been looked at under different conditions. This paper willserve as a background paper in order to expand research further in thedirection of making biogas based poly generation system as a successfulbusiness solution in rural areas.
