Solar Biomass Hybrid System For Cold Storage & Power Generation

  1. 1. Solar Biomass Hybrid System For Cold Storage & Power Generation Anand Upadhyay, Research Associate The Energy and Resources Institute
  2. 2. 1. Background 2. Project 3. System details 4. Future plans31-08-2012 2
  3. 3. Background31-08-2012 3
  4. 4. The Good• India is the 2nd largest producer of fruits and vegetables in the world.• Horticulture provides 6.5% of the countries GDP, 13% of employment and accounts for more than 9% of Indian exports with only 9% crop acreage.31-08-2012 4
  5. 5. The BadHarvested fruits and vegetables, worthRs.60,000 crores (USD 12 billion)are lost due to lack of post harvest handling and storage31-08-2012 5
  6. 6. and The Ugly…31-08-2012 6
  7. 7. • Short fall of 10 million tones storage capacity• Energy costs account for about 30% of operating costs.31-08-2012 7
  8. 8. 31-08-2012 8
  9. 9. Small sized cold storages should be built…31-08-2012 9
  10. 10. …should be built near agriculture field itself31-08-2012 10
  11. 11. In short…Small sized cold storages should be built nearagriculture field itself31-08-2012 11
  12. 12. BUT… Poor power supply31-08-2012 12
  13. 13. Most of the Indian landscape is blessed with perennial solar energy + biomass in villages31-08-2012 13
  14. 14. In 2006, TERI started working on a conceptwhereby indigenously available biomass andsolar resources could be used to operate small,decentralized cold storage right at the villagelevel31-08-2012 14
  15. 15. Interactions…Consultations with• National Horticulture Board• District Horticulture Offices• Central Food Technological Research Institute 31-08-2012 15
  16. 16. … Elaborate exercise to understand the fieldrequirements.31-08-2012 16
  17. 17. The System• A 15 kW Vapor Absorption Machine (VAM) coupled with a 50 kWe Biomass Gasifier system and a field of solar collectors.• Locally available biomass is used in the Biomass Gasifier to produce synthesis gas, which will then be used to run an engine to produce electricity.• Additionally the heat energy from the sun and gasifier is being utilized by the VAM to produce cooling effect in the cold storage.31-08-2012 17
