Transcript

  • 1. Renewable Energy WorkshopBy Kevin MacLennanEnvironmental Engineer
  • 2. Overview•  Introduction to Renewable Energy– What is it?– Why Use it?– What are the Technologies•  Where is it suitable•  Available Financial Support•  Can I use Renewables•  What next
  • 3. Before We Begin…•  Before thinking about renewable energy,consider the energy hierarchy:– Reduce the need for energy– Use energy more efficiently– Use Renewable Energy– Use fossil fuels efficiently
  • 4. Before we begin…
  • 5. Why Use RenewableEnergy?•  Renewable Energy can:– Reduce environmental impact– Save money– Increase security of supply– Improve the ‘green’ credentials of yourorganisation
  • 6. Remember…•  The biggest returns will always be realisedfrom using renewable energy on site
  • 7. What is Renewable Energy?•  Renewable energy is energy that comesfrom resources which are continuallyreplenished such as sunlight, wind, rain,tides, waves and geothermal heat.
  • 8. Renewable Technologies:•  Wind•  Solar PV•  Solar Water Heating•  Biomass (including Biofuels)•  Hydro-Electricity•  Geothermal and Heat Pumps•  Anaerobic Digestion
  • 9. Wind Power – What is it?•  Power from the windIt’s been around for years
  • 10. Wind Power – Types ofTurbines
  • 11. Large Wind –Suitable for yoursite?Some points to consider:• Is it windy – (Wind Energy Database)?• Is there space?• Connection to the National Grid• Planning permission• High Capital Costs
  • 12. Small Wind – suitable for yoursite?•  Again, is it windy (Wind EnergyDatabase)?•  Lower capital costs•  Do you have an electrical baseload?•  Are there space, planning restrictions?
  • 13. Wind Energy Database
  • 14. Solar PV
  • 15. Solar PV – Electricityfrom the Sun•  It is a proven technology – in the rightlocation•  Low efficiency (~10%) and low energyoutput•  Works best where it’s sunny•  Not financially viable in UK withoutNIROCs (typical payback of 60+ years)
  • 16. Solar PV – is it right for your site?•  Do you have rood space?•  ~£1,600 per kW•  14 year payback without NIROCs•  6.1 year payback with NIROC’s
  • 17. Solar Water Heating
  • 18. Solar Water Heating
  • 19. Solar Water Heating•  Slightly more effective than PV•  Can be effective in the right circumstances•  High capital costs compared to returns•  Can not be considered as a primarysource of hot water.•  Benefits from RHI support
  • 20. Solar Water Heating – Right foryour site?•  Available Roof Space?•  DHW demand?•  £500 per m2 of panel•  ~£10-12 saving per m2 per year withoutRHI – 42 year payback•  ~£30 saving per m2 per year with RHI (upto 200 kWth output) – 17 year payback
  • 21. Biomass Heating
  • 22. Biomass Heating – is itsuitable for your site•  How do you currently heat (oil, gas,electricity)?•  Can be very attractive compared toelectricity or oil•  Tried and tested technology•  Can often be integrated with existingsystems.
  • 23. Biomass Heating – is itsuitable for your site•  Requires a lot of space, particularly for fuelstorage.•  Most suited to predictable constant loads –good for meeting a heating baseload•  Generally works best in tandem with oil orgas heating•  Benefits from RHI support
  • 24. Hydro Electricity
  • 25. Hydro Electricity
  • 26. Hydro Electricity•  Again, a tried and tested technology•  Can be very predictable in terms of output•  Highly dependant on site conditions•  Capital costs can be high•  Well supported by NIROC’s
  • 27. Hydro Electricity – anopportunity for you?•  Is there a water source on your site?•  Is there a drop in height (head)?•  Is there space to exploit it?If the answer to all of the above is yes, thenperhaps Hydro is worth exploring further.
  • 28. Geothermal and Heat Pumps
  • 29. Geothermal and Heat Pumps
  • 30. Geothermal and Heat Pumps•  High capital costs for relatively low returns•  May be cost effective where excavation isbeing carried out•  Unlikely to be suitable as a primary heatsource•  Paybacks typically 15+ years
  • 31. Anaerobic Digestion
  • 32. Anaerobic Digestion
  • 33. Anaerobic Digestion•  Gas from organic material, such as:– Catering waste– Vegetables– Milk– Manure
  • 34. Anaerobic Digestion•  Increasingly popular technology•  Requires space and a waste stream•  Relatively labour intensive•  High capital costs•  Can be tricky to get right
  • 35. Anaerobic Digestion – rightfor you?•  Do you have a waste stream?•  Do you have space?•  Can you use the gas?
  • 36. Funding Support•  Northern Ireland Renewable ObligationCertificates (NIROC’s)•  Renewable Heat Incentive (RHI)•  Interest Free Loans
  • 37. NIROC’s•  Renewables Obligation Certificates(ROCs) can be sold on an open market•  ROCs earned per MWh of electricitygenerated (dependant on technology)•  Currently worth ~£50
  • 38. NIROC’s
  • 39. Renewable Heat Incentive•  Financial incentive for renewable heatsources:– Solar Water Heating/Solar Thermal– Geothermal energy– Heat Pumps– Biomass– CHP with biomass fuel
  • 40. Interest Free Loans•  Available from the Carbon trust to SME’s•  Based on amount of CO2 saved on site –doesn’t count electricity exported to grid•  Unsecured loans from £5,000 - £400,000
  • 41. Which one is right for you?•  Can any of the above work for your site?•  Using the hand-out, start working throughthe questions.•  Is there a potential project?
