• Biomass costs = 4 €/GJ_ar<br />
• Pre-treatment costs = 1.5 €/GJ_ptt_bm<br />
• Local biomass (truck transport)<br />
• Variable transport costs: 0.08 €/ton/km<br />
• Deprecation = 10 years (linear)<br />
• Required IRR = 12%<br />
• O&M costs: 7%<br />
• Scale factor = 0.7 (whole range)<br />
• Availability = 8,000 h/y<br />
• Pre-treatment efficiency<br />
(torrefaction) = 97%<br />
• Gasification efficiency<br />
(biomass to biosyngas) = 80%<br />
• Conversion efficiency<br />
(biosyngas to FT C 5 + liquids) = 71%<br />
