Costs for consumption dependent material flows depend on plant
availability. On average about 7000 operating hours per year are
assumed, which corresponds to 80% plant availability during the
expected lifetime. This is consistent with operation experience in the
Puertollano IGCC plant [41]. Consumption dependent costs are dominated by the costs for slurry input. The price of slurry has been evaluated
by the authors of this study in a previous publication [26] and equals
about 35 €/MWh in the base scenario. Since the price for slurry has a
strong influence on production costs of syngas, further scenarios for
slurry production from biomass are illustrated in the discussion section.
According to the slurry production scenario, the transportation costs for
slurry are derived. The base scenario assumes an average transportation
distance of 250 km by rail and costs of 21.80€ per dry ton of slurry [42].
The price of electricity equals theannual average in 2010 of 99.30€/MWh
provided by the Federal Statistical Office in Germany [43]. The prices for
coal and naturalgas inputs are also estimated with theannual averages in
