Advantages - Disadvantages

� Relative low investment costs (except electrolyser), compared to classical methanation or Fischer Tropsch synthesis, based on solid fuels

� Not many full load operating hours per year� High storage costs for electricity, due to investment and losses

Does it make sense to store electricity?

Or is it better to convert electricity into transportation fuels?

as much H2 as available

Adjusting the H2:CO ratio by using the correct steam:CO2ratio for gasification

Operation without external hydrogen

Operation with external hydrogen



Questions to be answered

� Steam gasification is already available, but is CO2 gasification also possible� Gas composition� Tar content

� Load change velocity of synthesis� For FT a slurry reactor is used, so no problem?� For BioSNG a fludised bed is used, so also no problem?

� Detailed mass and energy balances

� Investment and operation costs

Lab scale Fischer Tropsch synthesis, which uses a slip stream of the biomass CHP Güssing









Conclusion

More info at http://www.ficfb.athttp://www.vt.tuwien.ac.athttp://www.bioenergy2020.eu

� Combination of biomass gasification with wind/photovoltaic is a interesting option

� CO2 gasification is possible and effects the gas composition by the reverse water gas shift reaction, only minor influence on tar content

� Carbon utilisation is much higher than in normal gasification� Load change in synthesis reactor is possible

� Detailed Mass&Energy Balances will be published in the near future

� Economic evaluation of the system is key question!

� Here it is renewable carbon, not fossil!
