In this paper, a geothermal and solar-assisted combined system is designed for the electricity and cooling of residences. The geothermal water from the geothermal resource and the heat transfer fluid heated in the parabolic trough collector is used as the heat source in the absorption cooling system. The organic Rankine cycle (ORC) generates power with geothermal water and heat transfer fluid from the absorption cooling cycle. The produced power is supported to the grid. Engineering Equation Solver (EES) and Aspen Plus program are used for thermodynamic and thermoeconomic analysis of the combined system. In these analyzes, the geothermal and solar energy values of Afyonkarahisar city are considered. Geothermal water at a temperature of 130 ºC and a mass flow rate of 85 kg/s and a solar source at 600 W/m 2 radiation is used for the combined system. Parametric studies are performed to demonstrate the way unit electricity and cooling costs change according to the geothermal water temperature and solar radiation. The cooling capacity and the net power output of the system are 2720 kW and 2235 kW, respectively. The unit costs of cooling and electricity in the combined system are calculated 0.

“…Thermodynamic systems that transform economic parameters into operational expenses can be referred to as "work-economics." The advancement of thermoeconomic theory allows the usage of these systems to calculate the operational costs associated with the decrease in useful energy due to the irreversibility of the conversion process [18,19]. Moreover, the exergy-economic method is required to optimize costs by assessing the energy losses and inefficiencies within a system and determining its effectiveness.…”

The power plants in Indonesia are mostly used to supply energy for the industrial sector, including the upstream oil and gas as well as mining companies. Several companies operating in Riau contribute to the status of the region as the largest oil producer in Indonesia. These companies rely on self-generated electricity for their operations with subsequent impact on the environment. Therefore, this research was conducted to analyze the flow of energy, exergy, exergoeconomic, and environment at the 6 MW power plant operated by BOB - PT Bumi Siak Pusako - Pertamina Hulu. The second law of thermodynamics was used to evaluate energy efficiency as the maximum achievable effort. This was further integrated with economic principles to appraise the useful and wasted costs associated with thermodynamic systems through the concept of exergoeconomics. The results showed that the thermal efficiency of the gas turbine power plant was 42.85% and the exergy efficiency was 33.22% with the largest loss recorded in the combustion chamber to be 3.091 MW in the form of vibration, friction, or expansion of the components. It was also discovered that the exergy efficiency of each component was above 75%, thereby indicating the components of the gas turbine power plant components were in good condition. Moreover, the largest exergy destruction cost was 2349.16 USD/h and the exergy cost was 3,778.05 USD/kWh. The exhaust emission generated by the gas turbine power plant was 0.21 kg/s or equivalent to 0.1425 kg/kWh requiring a forest area of 11.63 ha. The results showed that the analytical method used could be comprehensively developed and applied to other power plants in Indonesia. It could also be used to understand system performance, identify energy losses, optimize energy efficiency, and link economic aspects with energy use.

“…According to obtained results, the total cost rate and exergy efficiency of the overall plant are 0.1764 US$/s and 58%, respectively. Ghiasirad et al 37 performed a thermoeconomic investigation of a geothermal‐powered power cycle to supply heating, cooling, power, and freshwater generation. The freshwater production capacity, net power, and payback period were determined to be 92.1 m 3 /day, 78.5 kW, and 5.6 years, respectively.…”

Energy, exergy, economic, exergoenvironmental, and environmental analyses are reported for a novel polygeneration system consisting of a geothermal cycle, a CO2 cycle, a reverse osmosis unit, an electrodialysis unit, a lithium bromide absorption chiller, and a liquefaction unit for natural gas. The proposed system is able to produce electricity, cooling, desalinated water, sodium hydroxide, and hydrogen. To study the environmental aspects of the proposed facility, the associated social cost of air pollution is determined. This parameter implies a comparison between nonrenewable and renewable energy systems to produce the same amount of electricity, while the amount of air pollutants generated and their associated costs are considered. Three scenarios are introduced. The results indicate that the system produces 631 GWh/year electrical energy, 465 GWh/year cooling, 6.22 ‎ton/year NaClO, 1.57 × 108 m3/year hydrogen, and 386,000 m3/year potable water for a geothermal working fluid supplied with mass flow rate of 100 kg/s at a temperature of 150°C and a pressure of 457.5 kPa. Also, the calculated values of the energy and exergy efficiencies are 58.3% and 94.2%, respectively. The payback period is determined to be 5.3 years. The net present value ‎is found to be ‎113.6 million US$ which is lower than that for all the nonrenewable‐based scenarios considered.
