Abstract

In this study, a novel multigeneration energy system based Brayton cycle is designed to generate power, compressed hydrogen, heating, drying and fresh water. The multigeneration system consists of the Brayton cycle, regenerative Rankine cycle, s-CO2 power cycle, t-CO2 power cycle, hydrogen production and compression plant, fresh water production plant and drying plant. In the evaluation part, energy and exergy analyses have been performed with a parametric analysis. The overall power production capacity of the system has been found as 13029 kW, and hydrogen production rate is 0.0624 kg/s. According to the thermodynamic analysis results, the overall energy and exergy efficiencies of the plant are 55.62% and 51.28%.
