Commercial Use of Biomass for Generating Electricity in a Small Village Reun Rina

Presentation Outline Introduction Production of Biogas Site Analysis Estimated Performance Conclusion

Introduction There is a lack of electricity access in rural areas About 200 houses don’t have enough energy to use Available source of biomass Animal waste Kitchen waste Market waste

Electricity of Biomass Anaerobic Digestion Use anaerobic digester for producing methane from animal waste Methane can be stored to run the generator

Production of Biogas Anaerobic digester Uses a tank above or below the ground Uses a mixture of animal waste and water(Slurry)

Chemical Equations of the Conversion

Site Analysis The analysis of using CFL vs. LED per bulb over 20 houses Financial saving /yr for 20 houses

Site Analysis An estimation of Cost of electricity used per year About 5-6 kWh of electricity must be generated every day to supply the villagers Cost of electricity consumption for 20 house per year of private electrical company: US$ 1344

Site Analysis Map of the village for mini-scale of Biomass-to-Electricity project

Estimated Performance The amount of biogas generated from various animal waste The available of source in the village is cow waste On average 1 kg of solid waste could produce 140 L of methane

Estimated Performance 11  m 3 of CH 4 runs 10kW generator for 1 hour(tested engine) Estimated cost of electricity $0.50/kWh Comparison cost: $3.00 vs. $4.20 /day.20 houses Total income is $986/yr Payback time 6 years

Conclusions Biomass(animal waste) is feasible for rural electrification This project can challenge the private electrical company It is better for environment and can provide 0.9kWh per 1  m 3 of CH 4 The lack of electricity in rural village will be solved and the village finance will increase If this project can be run, it could be copied to other areas
