Thermochemical Biomass Conversion for Decentralized Power Generation with the Inverse Brayton Cycle

Biomass is an important energy source for decentralized power generation. The combination of a two-stage thermochemical conversion unit with an inverse Brayton cycle (IBC) is the subject of current research activities. Several advantages are expected compared to commercially available concepts. A commercially proven turbocharger from the automotive industry is used for the IBC unit. No cost-intensive gas cleaning is required due to an almost dust- and tar-free biomass conversion. The influence of the feedstock characteristics on the thermochemical conversion, the emissions, and the overall plant performance is subject to process optimization studies. Furthermore, validation of the concept is the target of a demonstration phase planned for a later stage of the research activities.
