The EU Horizon 2020 project HiEff-BioPower (grant agreement No 727330, duration: 10/2016 – 09/2020) aims at the development of a new, innovative, fuel flexible and highly efficient medium-scale biomass CHP technology for a capacity range of 1 to 10 MW total energy output. It consists of (i) a fuel-flexible fixed-bed updraft gasifier, (ii) a novel compact gas cleaning system, (iii) a solid oxide fuel cell (SOFC) and (iv) a heat recovery system. The technology shall be applicable for a wide fuel spectrum (wood pellets, wood chips, SRC, selected agricultural fuels like agro-pellets, fruit stones/shells) and achieve high gross electric (40%) and overall (90%) efficiencies as well as equal-zero gaseous and particulate matter (PM) emissions. After the initial technical system design has been developed during the first project phase until 2018 (presented at EUBCE 2018), new preliminary experimental data has become available, as well as preliminary techno-economic analyses and market studies. Based on this new data, for the EUBCE 2019 conference this paper presents consecutive results from the first stage environmental impact assessment.
