Market trends and opp ortun ities for Gasif ication Products …
Trends and Opportunities …
Chemicals e.g. Methanol, Polypropylene, Ammonia,…
Is and will remain the market with the highest realization potential (CtC/BtC 1)
Synthetic Natural Gas
Serious alternative for (coal rich) countries, with lack on cheap natural gas availability
Alternative Tran sportation Fuels (CtL/BtL2) High-quality diesel from FT 3-synthesis Fuels with higher biomass content
Volatile oil and gas prices, security of supply concerns and climate protection cause search for alternative fuel sources
Refinery Hydrogen For upgrading products in refineries or in oil sands processing
Increasing demand for cleaner and lighter fuels are the drivers for higher H 2 consumption within refineries
Power • Large scale IGCC 4 with CCS5 as environmental friendly alternative to Steam Power Plants • Small scale power production via high efficient Biomass gasification systems
• High dependency on environmental legislation • Currently weak demand for CO 2 capture and
storage solutions • Availability and low energy density of biomass
drive gasifier capacity and location

Bt L 1 / BtE2 – Global gasi fi er m arket USA/Canada/Mexico: • Push through subsidies already in place
Markets • BtL projects mainly focused on markets for industrial scale chemical / transportation fuels production
Western Europe • Large scale projects in Netherlands and Finland under development • Subsidies available
Japan: Feed-in-tarif available
• Bt E mainly used for small scale power generation
Political / Economics Drivers • Financial decision guided by size and location, availability of feedstock, its energy content and processing costs
China • Underdeveloped as of today, but government policy and subsidies announced
• Insufficient grid expansion (developing countries)
Asia Pacific Region (India/Indonesia/Malaysia/ Thailand/Vietnam/…): • Could support electrification of rural and remote areas, growth rate for small/medium scale applications
• Public opinion against fossil fuel plants (industrialized countries)
South-America: •Opportunities for BtL/BtE at sugar plantations (bagasse) and croplands

BtL…Biomass to Liquids; 2BtE …Biomass to Energy
• Gasifier application in renewable applications forecasted to grow within the next years/decades • Short / Mid-term market will be dominated by small / medium-scale applications • Large scale lighthouse projects under development • Availability and low energy density of biomass drive gasifier capacity and location • Subsidies or feed-in-tariffs are key for biomass Page 6

Block flow diagram
Preliminary engineering results: • Ship transport by Handymax or Panamax bulk carriers • Buffer storage envisaged for 2 weeks, possibly in pyramid silo’s • Density of torrefied material is fundamental for performance of gasifier • Ash content of biomass is fundamental for gasifier design • Additional bio-fuel storage is required
