  1. 1. Biomass <ul><li>Introduction </li></ul><ul><li>The sources of Biomass. </li></ul><ul><li>The uses of Biomass. </li></ul><ul><li>The advantages and disadvantages. </li></ul><ul><li>Biomass in the future. </li></ul><ul><li>Conclusion. </li></ul><ul><li>Recommendations </li></ul><ul><li>Reference Bibliography. </li></ul>
  2. 2. Introduction <ul><li>What is biomass?? </li></ul><ul><li>The total mass of living matter within a given unit of environmental area. </li></ul><ul><li>Plant material, vegetation or agricultural waste used as a fuel or energy source. </li></ul>
  3. 4. Biomass Resouces <ul><li>1.Wood and agricultural biomass(wood logs, chips, sawdust, bark and other organic material. </li></ul><ul><li>2. Solid waste, by burning garbage heat and energy is produced. </li></ul><ul><li>3. Landfill gas, Methane gas is produced by the bacterial decay of dead plants and animals. </li></ul><ul><li>4. Alcohol fuels, Wheat, corn and other crops can be converted into a variety of liquid fuels including ethanol and methanol. </li></ul><ul><li>- </li></ul>
  4. 5. Converting biomass energy into a useable energy source <ul><li>1.Direct incineration </li></ul><ul><li>2.Bacterial Decay. (methane gas produced by the bacterial decay of dead plants or animals. </li></ul><ul><li>3. Fermentation, Adding a yeast to biomass produces an alcohol called ethanol. </li></ul><ul><li>4. Conversion, Biomass can be converted into gas or liquid fuels by using chemicals or heat. </li></ul>
  5. 6. Uses of Biomass <ul><li>80% of biomass energy is produced for residential use. </li></ul><ul><li>79% of the biomass we use today comes from burning wood and chips. </li></ul><ul><li>Biomass is used to heat homes, Wood is burned in open fires or wood pellet boilers and stoves. </li></ul><ul><li>18% of biomass is produced for industrial use. </li></ul><ul><li>2% of biomass energy is produced for transport. </li></ul>
  6. 7. Advantages of Biomass <ul><li>The main Advantages of Biomass are: </li></ul><ul><li>Biomass is a renewable fuel source. </li></ul><ul><li>Biomass energy production results in minimal environmental impact. </li></ul><ul><li>Employment generation in rural areas. </li></ul><ul><li>Alcohol fuels are efficient and clean burning. </li></ul><ul><li>The availability of biomass fuels is universal. </li></ul>
  7. 8. Disadvantages of Biomass <ul><li>When combusted to produce energy it contributes directly to global warming. </li></ul><ul><li>An expensive source to produce and convert. </li></ul><ul><li>On a small scale there is a likely net loss in energy; as energy must be put in to grow the plant mass. </li></ul>
  8. 9. The future of Biomass <ul><li>Infinite fossil fuel resources are depleting. </li></ul><ul><li>Our dependency on oil must be reduced. </li></ul><ul><li>Renewable forms of energy generation will be requireded to serve the global energy requirements. </li></ul><ul><li>Ireland has a goal of 16%use of renewable energy by2020(3.9% in 2008) </li></ul><ul><li>Today it accounts for 10% of the worlds energy consumption. </li></ul>
  9. 10. Conclusions <ul><li>Today we have looked at the varies different aspects of Biomass including: </li></ul><ul><li>The sources. </li></ul><ul><li>The conversion of biomass to useable energy sources. </li></ul><ul><li>The uses of Biomass. </li></ul><ul><li>The advantages and disadvantages </li></ul><ul><li>The future of Biomass. </li></ul>
  10. 11. Recommendations <ul><li>Biomass offers a renewable solution to the fast approaching global energy crisis. </li></ul><ul><li>Biomass is more eco friendly on the environment than most other energy generation methods. </li></ul><ul><li>E.U.policy is setting onerous targets for renewable energy generation and biomass can be used to help meet these targets. </li></ul><ul><li>Biomass will create much needed employment in this Irish recession economy. </li></ul>
  11. 12. Thank you for your time. <ul><li>Are there any questions? </li></ul>
