Abstract:
Biomass is considered as an important, and maybe the most important,energy source for this century. An aspect of biomass is that this renewable
source can produce liquid (bio) fuels. The most optimal chain to produce
these liquids might be the combined production of the liquids and electricity
and heat: tri-generation. The overall efficiency for the generation of energy
biomass is higher than for conventional biomass gasification. The production
of Fischer-Tropsch (FT) liquids is today the most optimal route for producing
liquid fuels. FT diesel is directly applicable in the existing infrastructure
and is free from sulphur and aromatics. For the demonstration of integrated
systems ECN focuses on two lines of development: (1) large-scale dedicated
installations for imported biomass and (2) small- to medium scale for local
biomass and wastes. In a large plant (with a price for biomass of 3.6
Euro/GJ) electricity can be produced for 0.05 Euro/kWh and diesel for 0.22
Euro/litre (6.0 Euro/GJ). The overall efficiency of the FT synthesis will be
circa 62% and the energy flows for electricity and fuel are about equal. For
small-scale systems the local situation will determine the cost figures. 18
