BIOMASS Current Technologies and Future Projections

1
BIOMASSCurrent Technologies and Future
Projections

• ALEX EVANS

2
Biomass

• Production of energy from animal or plant waste
• One of the oldest forms of energy generation
• Second largest form of renewable energies
  generation

3
Agriculture and Forestry Waste

• Two Main groups
• Dry Combustible straw and forest waste
• Utilised using combustion, gasification or
  pyrolysis
• Wet Wastes vegetable roots and farm slurries
• Utilised using anaerobic digestion

4
Energy Crops

• Dry, high lignin crops combustion, gasification
  or pyrolysis
• Wet biomass converted to liquid or gas through
  fermentation under anaerobic digestion
• New Research!

5
Bio - Fuels

• Cereals and sugar beet ethanol
• Contribute to the running of 10 million cars in
  Brazil
• Reduce oil dependence on other countries
• Anaerobic Digestion - biogas
• Applications for stationary industrial engines
• Limited use in cars as it requires compression

6
Projections

• Current Use 2003 150 PJ
• Future Use 2025 600PJ
• Composed from 25PJ Agricultural and
  Forestry Waste
• 540PJ Energy Crops

7
Conclusions

• Potential not realised
• Could be the second largest provider in future
• Severe opposition to past plans
