Presentation Transcript

  1. RENEWABLES ENERGY & POWER BIOMASS, GOETHERMAL, HYDRO,TIDAL, WAVE, WIND, SOLAR

  2. NETT ANNUAL PRODN = 400 Bt/yr ENERGY STORED IN BIOMASS = 25000 EJ TOTAL WORLD ENERGY CONSUMPTION = 400 EJ/yr BIOMASS USE = 55 EJ/yr FOOD ENERGY CONS. = 10EJ/yr WORLD PRODUCTION & USE OF BIOMASS

  3. CONVERSION OF SOLAR ENERGY BY PHOTOSYNTHESIS PER HECTARE (2.47 A)

  4. WORLD POTENTIAL FOR BIOMASS ENERGY SUPPLY IN 2050

  5. MAX 50 MWe, or 4 TWh e in the UK

  6. POSSIBLE PROJECT 6500 TONNES PER YEAR WOOD SHREDDER AND BURNER FOR A TOMATO GROWER ON GUERNSEY SIMILAR TO THE COMPACTOWER AT AVONMOUTH

  7. Piddlehinton, about a million kWhe per year Direct combustion of chicken dung, Suffolk, 12.5 MWe plant. 1 ch=1W

  8. SORGHUM AND MISCANTHUS

  9. Ethanol yields from crop fermentation, in litres per hectare per yr Sugar cane, 400-12000, Corn, 250-2000 Sugar beet, 500-4000 Sweet potatoes 1000-4500 Wood 160-4000

  10. POSSIBLE PROJECT AERODYNAMICS OF POLLEN FLIGHT AND CAPTURE

  11. BIG/STIG SYSTEM, BIOMASS INTEGRATED GASIFIER AND STEAM INJECTED GAS TURBINE. UK PRODUCES 25 MILLION TONNES MSW PER YEAR, 90% LANDFILLED

  12. MSW PRODUCES LFG BY ANAEROBIC DIGESTION UP TO 300M3 GAS PER TONNE WASTE LIFETIME UP TO 10 YEARS

  13. 500 KW MARINE ENGINE DRIVEN GENERATORS

  14. GEOTHERMAL ENERGY • EARTH’S CORE AT 7000C • TEMP GRADIENTS ON AVERAGE 25C/KM • WET OR DRY HOT ROCKS • TINY COMPARED WITH SOLAR FLUX • WORLD PRODN ABOUT 6GWe & ABOUT 4GWt

  15. 3 COMPONENTS – AQUIFIER, CAP ROCK, HEAT SOURCE

  16. MILLIWATTS PER SQUARE METRE

  17. SOUTHAMPTON, 1800m, 70C, 2MWt, saves 1000tonnes oil/yr

  18. CREIL DISTRICT, N. PARIS Finite lifetime 20/30 yrs. Note that GHP schemes now being installed around the world
