Solar Biomass Hybrid System For Cold Storage & Power Generation Solar Biomass Hybrid System For Cold Storage & Power Generation Presentation Transcript

  • Solar Biomass Hybrid System For Cold Storage & Power Generation Anand Upadhyay, Research Associate The Energy and Resources Institute
  • 1. Background 2. Project 3. System details 4. Future plans31-08-2012 2
  • Background31-08-2012 3
  • 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
  • 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
  • and The Ugly…31-08-2012 6
  • • Short fall of 10 million tones storage capacity• Energy costs account for about 30% of operating costs.31-08-2012 7
  • 31-08-2012 8
  • Small sized cold storages should be built…31-08-2012 9
  • …should be built near agriculture field itself31-08-2012 10
  • In short…Small sized cold storages should be built nearagriculture field itself31-08-2012 11
  • BUT… Poor power supply31-08-2012 12
  • Most of the Indian landscape is blessed with perennial solar energy + biomass in villages31-08-2012 13
  • 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
  • Interactions…Consultations with• National Horticulture Board• District Horticulture Offices• Central Food Technological Research Institute 31-08-2012 15
  • … Elaborate exercise to understand the fieldrequirements.31-08-2012 16
  • 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
  • The SystemSolar Dishes Cold Storage Ammonia VAM Biomass Gasifier Gas Engine Electrical Power
  • The System Solar dishes Cold storageGasifiersystem VAM31-08-2012 19
  • To provide• 50 kW clean grid quality power• Cold storage facility for about 20 tonnes of fruits or vegetables. 31-08-2012 20
  • TRNSYS simulation results Initial cooling load profile after product has been loaded in cold chamberTRNSYSmodel Cooling load over next 30 days after product has been brought to storage temperature 31-08-2012 21
  • Project Site N Located in SEC campus, Gurgaon, near solar parabolic trough collector field31-08-2012 The Beginning… 22
  • Setting up of system31-08-2012 23
  • Before & After AFTERBEFORE 31-08-2012 24
  • Technological USPs • First of a kind in World • Ammonia based VAM – GAX cycle – built for subState of the ART zero temperature Renewable • Biomass – TERI’s Advanced Gasification System Energy • Solar –Fixed focus concentrating dish Grid • Electricity generated from gasifier & gas engine Independent System • Integration of Biomass gasifier, Solar dishes and Integration Ammonia VAM with Cold storage
  • SpecificationsCold Storage capacity : 20 MTCooling Capacity : 15 kWCold storage Temperature : 0 to 5°CGas Engine capacity : 50 kWeBiomass consumption : 60 kg/hr
  • Specific details on solar energy• 30% thermal energy met using Scheffler dishes• 4 dishes of 16 m2 each (from Thermax)• Detailed hourly simulation done using TRNSYS• Hybridization with biomass energy31-08-2012 27
  • System at site31-08-2012 28
  • Contd…31-08-2012 29
  • Complete system31-08-2012 30
  • Size flexibility Power Energy Cold Storage Size Source Generation Requirement Fruits Cooling Duty Biomass Grid quality Vegetables (15 to 50 power for kW) domestic, Self community, Flowers* Solar Sufficient and productive Dairy & loads Capacity Milk* (20 to 100 Fish & MT) Hybrid Meat** Under development
  • Derivative schemesEnergy side Technology Application variations Absorption Horticultural technology for Biomass positive temperatures Non horticultural Absorption technology for sub zero temperatures Food processing Solar Vapor compression technology for all temperatures Deep Freezing
  • Mix ‘n’ matchScheme • Biomass coupled with absorption Technology AScheme • Solar & Biomass Hybrid Coupled with Absorption Technology BScheme • Biomass coupled with vapor compression Technology C
  • Adsorption technologies31-08-2012 34
  • What all has been difficult• Simulating the system for sizing and predicting performance• Stakeholders !!! (in plenty)• System integration31-08-2012 35
  • Way forwardCurrent pilot system• Long term monitoring and tests to optimize future systems• System cost reduction• Field replications31-08-2012 36
  • Sincere thanks to owners of the photographs (which have been used in this presentation) who have shared their wonderful work on internet, and without which the audience would have been sleeping. Thank you so much ! Thank You!!! anand.upadhyay@teri.res.in31-08-2012 37
