Global Energy Flow Outlook 2030
Overview of the Global Potential of Biomass for Energy
World Primary Energy consumption (2006): 400 EJ/a
Role of Biofuels in theEnergy Economy System
“Energy Saving” – Reduction of useful energy consumption with same energy service, e.g. insulation of buildings
Increasing of Energy Efficiency in energy conversion, e.g. hybrid vehicles
(further) Increase of using Renewable Energye.g. biofuels, solar energy
Reduction of Greenhouse Gas Emissions, e.g. Kyoto-Target: minus 13% (2008-2012 ref. 1990)
Reduction of local pollutantse.g. PM10, NOx
Increasing of Energy Securitye.g. domestic renewable energy

Overview Transportation Biofuels1st and 2nd Generation1) (pure) vegetable oil2) Biodiesel
a) conventional biodiesel via esterificationb) hydro-treated biodiesel via hydration
3) Bioethanola) conventional bioethanol from sugar and starchb) lignocellulosic bioethanol
a) Fischer-Tropsch biofuels (z.B. FT-Diesel)b) Synthetic natural gas (SNG)c) Dimethylester (DME)d) Methanole) Synthetic hydrogen
7) Biological hydrogen8) (upgraded) Pyrolyses oil9) Biofuels from direct liquifaction
a) HTU-Biofuels from hydro-thermal upgradingb) CLC-Biofuels from catalytic low temperature conversion
OverviewBiomass Raw Materials
Biomassresources
Forestry- Residues from thinning- Residues from harvesting
Agriculture
- oil crops e.g. rape, sunflower- sugar crops: e.g. sugar beet, sugar cane- starch crops: e.g. wheat, maize- lignocellulosic-crops: e.g. short rotation forestry, miscanthus- residues: e.g. straw, manure, grass
Trade & Industry- sawn industry residues: e.g. bark- wood industry wastes: e.g. shavings- food and feed industry residues- bark- black liquour: - organic fraction of MSW- sewage sludge

Summary4 1. Generation: Biodiesel and Bioethanol (from sugar
and starch) until 2010 essential
4 Biogas and vegetable oil (niche markets)
4 2. Generation: Main focus on liquid synthetic biofuels (FT-Diesel) and lignocelulosic Bioethanol (SNG dependon development of CNG- infrastructure in transportation sector) after 2010+
4 Long term: hydrogen if everConsideration of biorefinery
