Bioenergy and waste
The vision is to broaden the scope of biomass utilisation into upgrading and to broaden the biofuel base as such.
Vision
The potential for increasing total traditional biomass utilisation for energy purposes is limited. The thrust of the activities is therefore twofold, one aim is to broaden the scope of biomass utilisation into upgrading and the other aim is to broaden the biofuel base as such. This in turn implies an enhanced focus on fuels for transportation and power generation with respect to traditional biomass and a focus on direct heating for more complex biomass, such as waste etc.
Challenges
An overall challenge is to develop technically feasible and cost efficient processes for the generation of a gas from biomass by thermochemical means that is suitable for subsequent upgrading. This includes development of techniques for improving the handling and feeding properties of the biomass and limiting the negative effects of the ash components. This through, for example, pre-treatment, such as torrefaction and/or leaching.
Additional challenges include further development of the fixed bed gasification of pellets based on agricultural residues and the high temperature gasification concepts. Clarification of the factors that influence defluidisation during fluidised bed gasification and development of robust techniques for the catalytic upgrading of the gas in harsh environments are also called for.
