Biomass Utilization for Energy Conversion Economic considerations

1
Biomass Utilization for Energy ConversionEconomic
considerations

• Dr. Bernd Dous
• Ministry of Economy and Trade
• Hamburg

2
Introduction

• Big Bang in the German supply with natural gas
• Start up of discussion about the energy supply in
  Germany now and in future security of supply
• Effects on costs of living and living standard
• The German situation demonstrated by data and
  information about Hamburg (infrastructural data)

3
Synergistic Effects of Waste Treatment and Energy
Conversion

• Example slaughterhouse Hamburg
• Important facts legislation and costs
• Results waste treatment under controlled
  conditions according the ecological legislation,
  energy production was secondary
• Today the aspects of energy supply are dominating

4
Technology and Cost Structure

• production, collection, pretreatment
• Storage
• Conversion process
• Distribution of products/energy
• Revenues
• Evaluation of specific conditions is essential

5
Market prices for selected materials

• Wood chops (with 35 water) 50 per 1000kg
• Wood pellets (dry) 200 per 1000kg
• Wood, fresh 50-80 per m3
• Biodiesel based on rape oil 0.95 per Liter

6
Benefits

• Revenue of thermal energy
• Revenue of electrical energy
• Revenue of by products/residues e.g. fertilizer
  from biogas plants
• Ecological improvements
• Improved sanitation
• Cleaner industrial and living areas
• Implementation of technical skills
• Specific evaluation necessary

7
Examples

• Slaughterhouses details are compiled in hand
  outs

8
Priorities/ranking/questions

• Decentralized production of electricity and
  thermal energy
• Development of infrastructure in the countryside
• Optimized treatment and utilization organic
  wastes from agriculture
• Treatment of industrial organic wastes/
  industrial waste water
• Sanitation as a sensitive sector (e.g problems of
  waste concentration)
• Combined utilization of electricity and thermal
  energy
• Modes of financing
• Public subsidies to help the start up
• RD activities

9
Final Remarks

• Prices for energy will increases significantly
• Uncertain timetable, rate and extend of
  increase of energy prices
• Scenario what happens when supply with primary
  energy is interrupted or comes to an end and what
  kind of precautions/technologies are possible and
  available in time?
