history of bio refineries i
History of bio-refineries I
  • a longhistory:
    • 1860  Nikolaus Otto
    • 1908  Henry Ford (Model T car)
    • 1930  a large explorationofcrudeoil
    • 1970  oil-priceshock
    • 20th century in Europe  bio refineries were built
    • Worldwide  usageofbiomassas an energysourcehasbeenrisingsharply

History of bio-refineries III
  • Bio-refineries in Austria
biorefineries in austria
Biorefineries in Austria
  • From 2003 to 2008, production capacity has risen almost tenfold
  • From 58.1 MW to 519.6 MW
  • Biodiesel production has risen from 95000 tons to 578000 tons from 2005 to 2008
  • First domestic bioethanol plant in Pischelsdorf opened in 2008 and satisfies demand with 240000 tons capacity
status
Status
  • $38 billion invested worldwide in renewable energy capacity
  • 7% of that in biomass electricity
  • 47 GW current capacity
  • Austria shows 10-30% growth
    • 519.6 MW in 2008
processes
Processes
  • Small-scale dedicated biomass plants still less efficient than co-firing in existing coal plants
  • Efficiency levels for dry biomass reach 30-34%
  • Municipal waste offers 22%
  • Biomass co-firing achieves 45%
  • Currently the most cost-effective biomass use
costs
Costs
  • Costs depend on availability of affordable local feedstock
  • If ample feedstock is available, co-firing in coal plants can produce competitively priced power at $20/MWh
  • Dedicated biomass plants require higher initial investments due to smaller size
  • Prices range from $40/MWh to $90/MWh
optimization and efficiency
Optimization and efficiency
  • Sustainable
  • Optimize use of resources
  • Minimizing waste
  • Maximizing benefits and profitability
  • Optimization can be achieved by future development in key areas and the efficient exploitation of chemical energy from biomass.
criticism i
Criticism I
  • A comparison of emissions through various forms of biological feedstock, compared to the emissions level of fossil fuels.
criticism ii
Criticism II
  • Increased demand for biomass causes competition for arable land and deforestation
  • Usage of food crops as feedstock drives up worldwide food prices and causes malnourishment
  • Safeguards must be established to ensure sustainable development of biomass usage
