A direct absorption parabolic trough solar collector (DAPTC) integrated with porous foam as a volumetric absorber has the potential to be applied as an energy conversion integrant of future renewable energy systems. The present study comprehensively analyzes a DAPTC in terms of exergy, economic, and environmental analysis for different porous configuration inserts in the absorber tube. Ten different arrangements of porous foam are examined at several HTF flow rates (40–120 L/h) and inlet temperatures (20–40 °C). The exergy efficiency, entropy generation, Bejan number, and pumping power are investigated for all cases. Obtained results indicate that fully filling the absorber tube with porous foam leads to a maximum exergy efficiency of 20.4% at the lowest inlet temperature (20 °C) and highest flow rate (120 L/h). However, the Bejan number reaches its minimum value due to the highest pumping power in this case. Consequently, all mentioned performance parameters should be considered simultaneously. Finally, the environmental and economic analyses are conducted. The results show that fully filling the absorber tube with porous foam reflects the best heat production cost, which can reduced the embodied energy, embodied water, and CO2 emission by 559.5 MJ, 1520.8 kL, and 339.62 kg, respectively, compared to the base case at the flow rate of 120 L/h.

“…Hence, the integration of renewable power technologies and the integration idea is treated as an original way that should help increase plant effectiveness and reduce CO 2 emissions 4 . Tukenmez et al 5 have examined a solar power‐based multigeneration power process to obtain H 2 and useful outputs and also performed an effectiveness assessment for efficient energy utilization. The driving source power required for the integrated plant operation was provided by using the parabolic concentrating solar power system.…”

Summary This paper proposes the design of a new solar power‐based multigeneration system for generating hydrogen, ammonia, methane, and other beneficial outputs. This combined plant consists of the solar plant, Rankine cycle, organic Rankine cycle, single‐effect absorption with ejector, carbon dioxide capture, hydrogen, ammonia, methane, drying, hot, and freshwater generation plants. The overall plant is investigated utilizing the Engineering Equation Solver software. The energy and exergy efficiencies of the integrated plant are computed as 0.6689 and 0.6227. In addition, the largest exergy destructions in the system are 6924 and 4037 kW, which occur at the Rankine cycle and solar power cycle, respectively. Moreover, the thermodynamic performance of the combined plant is investigated through parametric works and the impacts of plant working conditions on the plant efficiencies are evaluated.
