    • Trees
    • Grasses
    • Agricultural Crops
    • Agricultural Residues
    • Animal Wastes
    • Municipal Solid Waste
    • USES
    • Fuels:
    • Ethanol
    • Renewable Diesel
    • Hydrogen
    • Power:
    • Electricity
    • Heat
    • Chemicals
    • Plastics
    • Solvents
    • Chemical Intermediates
    • Phenolics
    • Adhesives
    • Furfural
    • Fatty acids
    • Acetic Acid
    • Carbon black
    • Paints
    • Dyes, Pigments, and Ink
    • Detergents
    • Etc.
    • Food and Feed
    - Enzymatic Fermentation - Gas/liquid Fermentation - Acid Hydrolysis/Fermentation - Gasification - Combustion - Co-firing Biomass Feedstock
  • 5. METHODOLOGY
    • Assumptions
    • - 50% are suitable for fermentation/gasification
    • Hydrogen produced via fermentation: 39 kgH 2 /ton BM
    • Hydrogen produced via gasification: 80 kgH 2 /ton BM
    • - Biomass heating value (HHV 19 MJ/kg)‏
    • - Specific CO2 emissions from gasoline: 69 tCO 2 /TJ
    • D = ( QH 2 *φ*10 -6 /Q G )*100
    • D = the percentage of gasoline displaced (%)‏
    • QH 2 = amount of hydrogen used in transportation (kg/yr)‏
    • - QH 2 = amount of gasoline used in Latvia in 2002 (TJ/yr)‏
    • - φ = Energy density of hydrogen (142 MJ/kg)‏
  • 6. RESULTS AND DISCUSSION
  • 7. RESULTS AND DISCUSSION
  • 8. RESULTS AND DISCUSSION
    • Stimulating the necessary capital investments to build production capacity and infrastructure
    • Accessing markets for sales of products at prices justifying investments, and maintaining sustainable supplies of feedstock
    • Having appropriate technologies and processes for meeting standards for environmental performance and environmental justice
  • 9. CONCLUSIONS
    • Our results show that there are enough residual biomass and energy crops in Latvia to produce up to 300% of the total gasoline currently spent in Latvia , by using gasification or fermentation technologies exclusively.
    • However, it would require that these residual biomasses are collected and fed to the most efficient conversion technologies available .
    • Substantial research and increasing numbers of desk study projects are needed to determine which pathway is more functional and cost effective .
    • Our results provide convincing evidence that Latvia should further participate in b iofuels research projects . This course of action would help ensure that Latvia maximizes value while benefiting from its significant renewable biomass resources .
