| description | The use of solar energy is vital for the future of meeting the energy demand in the world. Different high- or
medium-temperature solar-based power plants have been introduced and examined; however, the low exergetic
performance of the solar power-to-electricity process is the principal defect. Although using thermal energy
storage in such plants leads to continuous production throughout the day, it also increases the rate of exergy
destruction. To improve this deficiency, the present study suggests and studies the simultaneous use of thermal
energy storage and compressed air energy storage technologies in a high-temperature soar-based coproduction
system by considering a multi heat recovery technique. In this regard, the operation of the system is divided into
three periods of the day, namely, storing (low-radiation mode), charging (high-radiation mode), and discharging
(night times). Hence, a Brayton cycle equipped with a high-temperature solar field using heliostat mirrors is
established. In addition, an organic Rankine cycle is employed for heat recovery. In addition, a low-temperature
electrolyzer is utilized for hydrogen generation. The ability of the suggested framework is investigated from the
exergetic, sustainability, and financial aspects and is optimized by an advanced evolutionary algorithm. The
optimum state indicates that the objective functions, i.e., exergetic round trip efficiency and unit cost of the
system, are 26.17% and 0.159 $/kWh, respectively. Furthermore, the electricity capacity and hydrogen pro�duction rate are obtained at 7023 kW and 627.1 kg/h, respectively. Moreover, its sustainability index and
exergoenvironmental impact index are found at 1.66 and 2.30, respectively. |
