Biomasses tested in the pilot scale FICFB
gasifier
• Wood chips
• Wood pellets
• Saw dust (particle
size)
• Coal (fixed carbon)
All fuels can be used, if the ash melting point is above 1000°C
as pure fuel and fixed carbon below 25%.
Fuels with lower ash melting point or higher fixed carbon have
to be used as mixture (e.g. 15% straw works well)
• Sewage sludge pellets (ash
content)
• Animal residue (impurities)
• Straw (ash melting)
• Willow (energy crop)

Options for gas conversions
• CO-shift
• Conversion of hydrocarbons
– Reforming to H2 and CO and recycle
– Conversion to SNG
– Conversion to electricity and heat
• Mass and Energy balances for all 3 cases were
calculated
• Economics show, that reforming gives the highest
overall value (at the frame conditions in Austria)

Status BioH2
• Applied for NER300
• Technical diligence was good
• Economics due to high biomass price (110
€/tdry) were the main reason to be on the 3rd
place
• Project is on hold, but pilot plant is realised as
slip stream in Güssing
• Future applications are evaluated together
with gas industry

Current Status and Outlook
• Successful scale up of a dual fluidized bed steam gasification system from laboratory to industrial scale (within 10 years)
• Several industrial plants available with – High electrical efficiency (> 30 % with combined gas engine and ORC-process)
– No solid residues (only ash, carbon content <0,5 %)
– No liquid condensates
– European emission requirements are met
– High availabilities (>90 %)
– Three plants are already in operation (8-15 MWfuel)
• High potential for biofuels (BioSNG, BioFiT) – BioSNG, most suitable,
– BioFiT, research ongoing, scale up to 1 bpd is ongoing
• Biomass CHP Güssing and now also Oberwart is optimal for research, as synthesis gas is available for 7000 hours per year
