Bio cng & microgrids for rural electrification 1

  1. 1. Bio-CNG & Microgrids for Rural Electrification rajunair@gogas.in 1
  2. 2. Agenda[ Insert your [ Insert yourtext here ] text here ] 2
  3. 3. Current SituationIndia • 30 million tonnes of solid waste • 4,400 million cubic meters of liquid waste 3
  4. 4. Potential in India•Solid Waste: 1457 MW•Liquid Waste: 226 MW 4
  5. 5. Potential StatewiseWet waste from urban area, Banana Stem from farms,Vegetable Market area in Jalgaon (No :1 State Maharahtra) 5
  6. 6. Technology Urban Waste Solid Liquid Thermal Biological Incineration Land filling Composting Biomethanation Gasification Biogas Pyrolysis Power 6
  7. 7. Merits of Biomethanation• Preservation of environment• Residue used as soil conditioner• Energy generation• Carbon Credits 7
  8. 8. Technical feasibility of Biomethanation Plant Parameters related with Technical FeasibilityNeed for obtaining Ensuring process kinetics Waste at processingwaste with desired sitecomposition • Removal of non• Annual seasonal • Digester Temperature & pH biodegradablesvariation in wastecomposition. • Carbon to Nitrogen ratio • Removal of binders like soil• Identification of • Maintenance of particles, stones,points for collection COD/BOD values of the etc.of waste. reactor feed • Adjustment of• Source specific water content incollection of waste. the feed to the reactor. 8
  9. 9. Feedstock 75% 3 % of Global banana production 16 % of India’s banana production 66 % farmers involved in banana farming 25% 9
  10. 10. Advantage of banana stem•Bananas give very high biomassproduction•Easily available•Available in all seasons•Stems and leaves can be separated formore value addition 10
  11. 11. Commercial viability• Input 20 tons – Dry Matter 15 % – Output Gas 7,200 m3 – Output Electricity 1.2 MW• 96% pure methane• Production cost – Gas Rs.8.00 per kg Sell Rs.50 per kg – 1 kg gas = 4 Units electricity – 1 Unit = Rs.6.83 (Source: Solapur power) 11
  12. 12. Return on Investment Sell only gas ROI – 4 to 5 years Electricity generation ROI – 10 to 11 years 12
  13. 13. Target Customers– Khandesh Mall– Auto Rickshaws running on petrol– Power co- generation at Bhusawal power plant 13
  14. 14. Case for Micro grids 32% efficient 92 % efficient Electricity Bio CNG Extraction Extraction processing processing & Transport & Transport 95 % Noefficient Conversion Conversion 34% 93 % Distribution efficient Distributionefficient Delivered to Delivered to Customer 32% 92 % Customerefficient efficient 14
  15. 15. Conclusion•Technology is optimum at 36 C° suitable in a (sub)tropical climate like India• Biogas plant needs minimum maintenance costs andcan produce gas for at least 20 years without majorproblems and re-investments•The slurry / residue is a clean organic fertilizer thatpotentially increases agricultural productivity 15
