Abstract:
The work aims at investigating the performances of an innovative hybrid biomass/solar energy production system for domestic micro-scale combined heat and power (CHP) generation. The system is based on Organic Rankine Cycle (ORC) technology that represents an attractive option for sustainable and reliable energy supply in small-scale applications, where traditional plants are technologically and economically unfeasible. The proposed ORC can be fuelled by a biomass burner and a concentrated solar power (CSP) system. A parametric analysis has been carried out to define proper ORC configurations and suitable operating conditions. The performances of the innovative system have been compared with the traditional biomass-fired ORC unit. The investigation demonstrates that hybrid biomass/solar ORC system is an effective solution for micro-scale CHP generation. The possible application to the Italian residential sector has been analysed. Results illustrate that hybridisation permits to overcome the intermittency of the solar source, reduce the biomass consumption, and improve the global system efficiency.
