Abstract There is a strong correlation between electrification and rise in human development, but in developing countries access to electricity is often unreliable, unavailable, or unobtainable, especially from a centralized electric grid. Portable electrification using batteries provides an affordable energy source while sidestepping costs and regulations associated with physical transmission lines. In this paper, an anaerobic digestion system consumes organic waste and produces biogas that fuels an electric generator for battery charging. The paper presents a detailed approach for conducting an engineering economic analysis of the system. Two candidate business models to evaluate the potential of portable energy storage device distribution services of different sizes to return profit are proposed. The results offer a promising starting point for local entrepreneurs to implement similar business models, particularly at a small scale with a modest capital investment of about $1500, with revenue of about $100 per week, and a payback period of 18 months on the investment.
