Feedstock

Apart from wood (for the production of woodgas) a lot of other biomasses can be used for producing electrical and thermal energy. Coconutshells, ricehusks, olivekernels, bagasse, bushels from palm oil plantations are all suitable for biomass gasification. Doppelfeuer gasification reactors can be adjusted to almost any locally or regionally available feedstock. Thus any community or region can switch to decentralized production of electricity and thermal energy on a local basis.

The universal applicability of the Doppelfeuer Technology also does allow the use of fermentation residues in sustainable energy production. This after-use maximizes the energetic output from the energy crops and manure used in biogas plants and reduces the dangers of eutrophication. Sewage sluges from private households can also be put to use in gasification plants as well as energetically highly efficient mix-briquettes put together from biomass and household wastes. This can help to reduce the total amount of waste going to landfills.

The flexibilty of the Doppelfeuer gasification even allows to use fossil fuels (i.e. coal, lignite or brown coal) to produce energy in decentralized plants. This makes the Doppelfeuer the ideal transition technology from fossile fuels to sustainable use of biomass and residues for producing electrical and thermal energy locally to keep incomes and jobs in the energy consuming cummunities. While relying on coal these can develop the supply chains for sustainable energy production and then switch away from fossile fuels. Changing a coal-baded Doppelfeuer gasification plant to biomass takes about eight weeks only.
