The authors propose a novel small-scale power plant capable of generating electricity and thermal energy from both solid and gaseous biomass, to be employed in rural electrification projects. The proposed system is based on mature and cheap technology, derived from the automotive sector, ensuring very low capital costs and minimum maintenance. The presence of an externally fired gas turbine permits to achieve great fuel flexibility and avoid possible problems of fuel supply in remote and isolated rural communities. The proposed solution makes rural communities capable of achieving energy autonomy targets, following a circular economy paradigm. Three possible configurations have been studied with a thermodynamic analysis in order to estimate system efficiency. Thanks to the reduced fixed and variable costs, the system allows to achieve performances comparable with those of other state-of-the-art technologies usually adopted for rural electrification. A prototype of the proposed system is developed at Politecnico di Bari (LabZERO).
