In the course of the Horizon 2020 project HiEff-BioPower scientists are developing a new, fuel flexible and highly efficient medium-scale biomass CHP technology. It consists of a fuel-flexible fixed-bed updraft gasifier, a novel compact gas cleaning system, and a solid oxide fuel cell (SOFC). The system can utilise diverse residual biomass fuels, such as wood pellets, wood chips, short rotation coppice (SRC) or selected agricultural fuels (such as agro-pellets, fruit stones and nutshells). Despite the challenging fuels, the system achieves high gross electrical efficiencies of up to 40 per cent and overall efficiencies of up to 90 per cent. At the same time the system is characterised by extremely low levels of gaseous and particulate emissions.
In the peer-reviewed article "Development of a new highly efficient and fuel flexible medium-scale CHP technology based on fixed-bed updraft biomass gasification and a SOFC" the project partners describe the HiEff-BioPower system and the development in project phase I in detail. Among other things, the Wuppertal Institute is responsible for the environmental and overall impact assessment.
