description

Abstract The integration of renewable energy sources (geothermal, biomass, and solar) and desalination systems into novel polygeneration plants is investigated. Two main arrangements are considered: geothermal (GP) and biomass (BP) polygeneration. Both systems include concentrating photovoltaic/thermal solar collectors, a multieffect distillation system for seawater desalination, a single-effect LiBr-H2O absorption chiller, storage tanks, heat exchangers, balance-of-plant devices; a biomass auxiliary heater and geothermal wells are also included, in BP and GP, respectively. The systems can provide electricity and hot water, used for space heating, cooling, domestic hot water production, and drinkable desalted water. Both systems are simulated by means of a zero-dimensional dynamical simulation model. Thermoeconomic, exergy, and exergoeconomic analyses are also presented, aiming at defining the best values of the main design variables. Two case studies are discussed: city of Naples (BP) and Pantelleria island (GP), both characterized by solar and geothermal resources and scarcity of fossil fuels and freshwater.
