Renewable resources

  2. 2. Major sources of Power generation
  3. 3. Renewable Energy
  4. 4. Major Renewable Energy Sources SolarWind Biomass Waste to Geothermal Energy
  5. 5. Solar Energy That will be explained in the succeeding slide
  6. 6. Technology Concentrated Solar Power (CSP) Photovoltaic (PV)It consists of – It consists of –• Solar Collectors• Turbine •Solar Arrays• Generator & Transformer • Inverter• Cooling Tower • Transformer
  7. 7. Future Technology – Solar-Hydrogen Revolution Usable Waste high-quality Heat energy Storage The and environmentSolar light Transport Combustion Decomposition of water H WaterPower 2H2 + O2 2H2O 2H2O 2H2 + O2 2 VaporPlant
  8. 8. Advantages and Disadvantages Advantages Disadvantages Sun does not shineAll chemical and radioactivepolluting byproducts of the consistently.thermonuclear reactionsremain behind on the sun, Solar energy is a diffusewhile only pure radiant energy source. To harness it, wereaches the Earth. must concentrate it into an amount and form that we can use, such as heatEnergy reaching the earth is and electricityincredible. By onecalculation, 30 days of Addressed by approachingsunshine striking the Earth the problem through:have the energy equivalent of 1) collection,the total of all the planet’s 2) conversion,fossil fuels, both used and 3) storage.unused!
  9. 9. Global & India scenario Global growth of Solar Power State-wise Power Generation 1.2% 8% 1.5% 2.2%MW 20.2% 66.9% Installed Capacity (as of 2011) : 979.4 MW Year
  10. 10. India’s Leading Players in Solar Technology.....
  11. 11. Other ApplicationsArchitecture & Agriculture & Solar Vehicles WaterUrban Planning Horticulture TreatmentSolar Sewage Solar WaterTreatment Heating Solar Lighting Cooking
  12. 12. Biomass Energy It is organic material made from plants and animals (microorganisms). It contains stored energy from the sun. That will be explained in the succeeding slide
  14. 14. Technology Feed Gas Drying Zone DistillationThe main products Zoneobtained from Biomass – Reduction• Methane Gas Zone• Ethanol Hearth Zone• Biodiesel Air Ash Zone
  15. 15. Growth in Recent Times Present Installed Capacity in India List of Commissioned Biomass Projects (as of 31.03.11) 8.2% 8.75% 22.24%MW 13.64% 18.33% 13.71% 15.13% Year India’s Potential (2012) : 25,000MW
  16. 16. Interesting Facts
  17. 17. Positives & Not-so Positives Pros Cons
  18. 18. Leading Players of Biomass Energy in India
  19. 19. Geothermal Energy That will be explained in the succeeding slide
  20. 20. Technology Average gradient: – 2.5 - 3.0oC / 100m Variation: – 1.0 - 25oC / 100m So if assuming average, temps at depth will be: 0m 15°C 2000 m 70°C 4000 m 120°C
  21. 21. Types of Geothermal Power PlantsDry steam Flash steam Binary steam
  22. 22. Interesting Facts about Geothermal EnergyThe Cerro Prieto GeothermalPower Station is the largestgeothermal power station inthe world. Geothermal production of energy is 3rd highest among renewable energies! In Iceland, Geothermal Energy provides •86% of their space heating •16% of their electricity generation Produces 5% of California’s electricity, heats thousands of homes, greenhouses, office buildings.
  23. 23. Positives and Not-so Positives Pros ConsUseful minerals, such as zinc and silica, canbe extracted from underground water. Brine can salinate soil Geothermal plants do not require a Extracting large amounts of water can lot of land, 400m2 can produce a cause land subsidence, and this can lead gigawatt of energy over 30 years. to an increase in seismic activityGeothermal electric plants production in Can release H2S, the “rotten eggs” gas.13.380 g of Carbon dioxide per kWhGeothermal plants can be online There is the fear of noise pollution90%-100% of the time. during the drilling of wells
  24. 24. Direct Uses of Geothermal Energy Space Heating Melting Snow DryingAquaculture Hot water Air ConditioningIndustrial Processes Greenhouses Resorts and Pools
  25. 25. India Scenario Indian geothermal provinces have the capacity to produce 10,600 MW Exploration of Himalayan provinces could yield enormous geothermal energyIndias fist Geothermal power plant with aninitial capacity of 25 Megawatts will becoming up in Andhra Pradeshs Khammamdistrict by 2012.
  26. 26. Major PlayersGlobal Companies Indian Companies
  27. 27. Waste to Energy That will be explained in the succeeding slide
  28. 28. Technology Different ProcessesMost WtE processes produceelectricity directly throughcombustion, or produce acombustible fuel commodity, suchas methane, methanol, ethanol orsynthetic fuels
  29. 29. Future projectsEast Delhi Municipal Corporation to build twoplants at Ghazipur of 16 MW and a capacity of46 lakh metric tonnes Solar Bio Energy System commissioned its first Thermophillic Biomethanation plant in Solapur, Maharashtra of 4 MW and a capacity of 80 tonnes organic compostTihar Jail ties up with BARC to producebiogas and manure frombiodegradable kitchen waste
  30. 30. WtE in a nutshell Advantages Interesting Facts Commercial AspectsThe majority of waste that Segregated municipal solid waste On average, one ton of is generally not available at thewould normally go into waste produces 525 plant sitelandfill sites can be re-used kilowatt-hours (kWh) ofThe fuel is obtainable cheaply electricity Lack of financial resources with Municipal Corporations/Urban Reliable source of fuel Each year the average Local Bodies family throws away 1.5 Lack of conducive policy guidelines Disadvantages tons of rubbish from State Governments in respect Thousands of ton of of allotment of land, supply ofWtE facilities are expensive Metal can be recovered garbage and power purchase / from the ash by recycling evacuation facilitiesThe public at large is stillunconvinced that WtE is free The efficiency of a waste-to-energyfrom harmful chemicals plant is 20 - 30 %.
  31. 31. Present Installed Capacity in India Total Capacity (2011) : 1683 MW 62 MW 191MW 73 MW 78 MW 176 MW 112 MW 151 MW 123 MW 131 MW 148 MWIt’s a new concept in thecountryCommercial technologiesare required to be imported
