In this paper, the energy, exergy, and economic analysis of a novel integrated power plant is investigated. The novel power plant is integrated by using the heliostat solar receiver, the heliostat solr reciever is integrated with many types of traditional power plants such as the gas turbine cycle, air-bottoming cycle, and absorption refrigeration system. Also, the integration of the heliostat solar receiver to heat the exhaust air from the compressor to reduce the natural gas consumption within the gas cycle has been investigated. For the proposed configurations, energy, exergy, and economic analysis for Tehran, Iran (35.689°N, 51.5°E) has been conducted. The model has been validated using previously published results of other authors. Since the investigated configurations are innovative and to the best of our knowledge a similar whole system does not exist in the literature, each cycle has been validated separately. Results and comparisons are given for six different combinations: gas cycle, gas cycle with air bottoming cycle, and gas cycle with air bottoming cycle and absorption refrigeration system. The previously mentioned cycles are analyzed again but this time with integrating them with heliostat solr reciever. The comparisons study is conducted in terms of monthly average energy efficiency, monthly average exergy efficiency, annual average energy efficiency, annual average exergy efficiency, net present value, simple payback period, payback period, and internal rate of return. Results show that adding the heliostat solr reciever to the different cycles minimizes the fossil fuel consumption and enhance energy performance very significantly, for example the energy and exergy efficiencies are increased from 44% up to 69%. Regarding some economic indicators such as the internal rate of return parameter, the results show that the highest internal rate of return belongs to the combination of the gas cycle with air bottoming cycle and absorption refrigeration system with the value of 0.48 and the combination of the gas cycle combined with heliostat solar receiver has the lowest value of internal rate of return of 0.16. As a result of the reduction in fuel consumption savings and other economic indicators are achieved in addition to better environment impact. Finally, the integration of heliostat solar receiver in power cycles shows many advantages mainly in hot areas where solar radiation is high.

The use of renewable energy systems for domestic and industrial sectors is growing at a rapid rate due to the increase in population and due to the restrictions set by governments worldwide in decreasing the green gas emissions. Among one of the most popular renewable energy resources is solar energy which can be applied easily for domestic use such as space cooling and district heating. Moreover, it can be applied to produce fresh water and drying technology, electricity production. In this work, applications of low-temperature solar collectors are presented and discussed in detail. Different applications of flat plate collectors, photovoltaic (PV) solar cells, parabolic trough collectors (PTC), and evacuated tube collectors (ETC) are used to drive desalination plants for freshwater production, heat pumps for residential buildings heating, absorption chillers for space cooling and providing houses with electricity. Cooling methods of PV cells are discussed using different techniques such as phase change material, forced air and water flows to keep the PV cells operating efficiently. The progress of using low-temperature solar collectors in Europe, North America, Asia, Africa, and Australia is presented and discussed. Review of energy and exergy analyses for the applications of solar collectors are demonstrated to determine the performance characteristics of solar systems. Moreover, an economic assessment is conducted to find out the feasibility of solar systems applications from an economic viewpoint. Finally, the International Energy Agency (IEA) vision and prospects for solar energy applications are presented. This study will serve as guidelines for engineers who are involved in solar energy to help them in finding the most suitable applications of low-temperature solar collectors.

Due to the high amount of natural gas resources in Iran, the gas cycle as one of the main important power production system is used to produce electricity. The gas cycle has some disadvantages such as power consumption of air compressors, which is a major part of gas turbine electrical production and a considerable reduction in electrical power production by increasing the environment temperature due to a reduction in air density and constant volumetric airflow through a gas cycle. To overcome these weaknesses, several methods are applied such as cooling the inlet air of the system by different methods and integration heat recovery steam generator (HRSG) with the gas cycle. In this paper, using a heliostat solar receiver (HSR) in gas and combined cycles are investigated by energy, exergy, and economic analyses in Tehran city. The heliostat solar receiver is used to heat the pressurized exhaust air from the air compressor in gas and combined cycles. The key parameter of the three mentioned analyses was calculated and compared by writing computer code in MATLAB software. Results showed the use of HSR in gas and combined cycles increase the annual average energy efficiency from 28.4% and 48.5% to 44% and 76.5%, respectively. Additionally, for exergy efficiency, these increases are from 29.2% and 49.8% to 45.2% and 78.5%, respectively. However, from an economic point of view, adding the HRSG increases the payback period (PP) and it decreases the net present value (NPV) and internal rate of return (IRR).

Waste heat recovery from industrial processes has attracted much attention in the energy field in the past few decades. This paper introduces a new configuration of the triple cycle including gas and steam cycles as well as an organic Rankine cycle (ORC), for energy recovery from the hot exhaust gas. Also, the amine carbon capture system (CCS) is used to separate and store carbon dioxide from the hot exhaust gas. For this novel system, energy, exergy, economic, exergoeconomic, and exergoenvironmental (5E) assessments are accomplished. The results reveal that adding steam and ORC cycles to the gas cycle increases the energy and exergy efficiencies to 71.8 and 73.7, respectively. However, integration of the CCS unit to this system reduces energy and exergy efficiencies to 50.5 % and 51.9 %. The economic results for the proposed system show that SPP and PP are both 1.5 years. Moreover, NPV and IRR are found to be 3.13 × 09 $ and 0.68 respectively. Moreover, the carbon capture system (CCS) unit can avoid 627,000 metric tons of CO2 emissions annually.

This review deals with organic Rankine cycle powered by geothermal resource which is one favorable substitute for conventional fossil energy. Organic Rankine cycle power plants are suitable for utilization of low-temperature energy sources (low grade energy) such as geothermal resource having low temperature (below 150 ᵒC). The applications of organic Rankine cycle for electricity production from geothermal energy resource was reviewed first, where the choice of geothermal energy resources and organic fluids was discussed for different ORC configurations and operating conditions. Hybrid optimization approaches for the purpose of maintaining long term performance of enhanced geothermal system reservoirs were also summarized. Furthermore, an in-depth review of energy and exergy efficiencies of ORCs was conducted. Key factors that influence the energy and energy efficiencies of organic Rankine cycle were discussed in detail. Then, the economic indexes such as electricity production cost and levelized cost of electricity for different organic Rankine cycle configurations were compared with other conventional power generation systems to examine the commercialization of the Organic Rankine cycle. Finally, life cycle assessment that evaluates the whole life performance of geothermal organic Rankine cycle energy systems was reviewed. The Environmental impacts of geothermal ORC were also considered. Compared with other review papers on geothermal organic Rankine cycle s, the present review provides the latest materials for more systematically surveying the geothermal organic Rankine cycle, which will be a valuable source of guidance and directions for engineers and researchers in this field.

A novel multi-generation energy system is proposed consisting of a solar gas turbine system, multi-effect seawater desalination, LNG cold energy recovery unit, and a double effect absorption chiller. In addition, different working fluids of the ORC system are examined to select the suitable working fluid in terms of global warming potential and exergy efficiency of the system. Subsequently, energy, exergy, and economic (3E) analyses are performed to comprehensively evaluate the energy system. Besides, a parametric study is conducted to assess the effect of the most influential decision variables on the proposed system. Afterward, the novel multi-objective spiral optimization (MOSPO) algorithm is introduced to minimize total cost rate of the system while maximizing the exergy efficiency as the conflicting objective functions. The proposed algorithm is developed to optimize the decision variables effectively. To ascertain the final optimum solution point, three conventional methods i.e. TOPSIS, LINMAP and Shannon’s entropy are implemented. The results revealed that exergy efficiency and total cost rate of the system at the baseline are 60.05%, and 36.75 $/h, respectively. Furthermore, the net power output of the system would be 106.5 kW in addition to 0.7703 kW heating load, 56.01 kW cooling capacity, and 35.74 kg/h fresh water production capacity. The eco-environmental assessment revealed the fact that the proposed renewable-based energy system is capable of avoiding 485 tons CO2 emissions annually, and product cost rate reduction up to 6 $/hr in comparison to coal and natural gas-based energy systems. Besides, the proposed MOSPO algorithm is compared with common optimization methods; accordingly, the conventional algorithms are selected for the comparison including non-dominated sorting genetic algorithm II (NSGA-II), the multiple objective particle swarm optimization (MOPSO) algorithm, the Pareto envelope-based selection algorithm II (PESA-II), and the strength Pareto evolutionary algorithm II (SPEA-II). The comparison results show that the proposed MOSPO algorithm is preferable according to the Taylor Diagrams showing the performance of the algorithms.

A novel configuration of a coal-fired cogeneration plant is proposed in this paper. This novel system is composed of combustion chamber, Rankine cycle, absorption chiller, alkaline electrolyzer, and methanation plant. In the proposed configuration, the heat of exhaust gas from the combustion chamber can be used in a Rankine cycle to produce electricity. The heat of exhaust gas also powers the absorption chiller to provide cooling. The exhaust gas flows through a sulfur extraction unit to separate sulfur from CO2 gas. To supply electrical power, wind turbines alongside the Rankine cycle are considered. A part of the produced electricity from both the Rankine cycle and the wind turbines can be used by an alkaline electrolyzer to produce hydrogen and oxygen. The CO2 gas from sulfur unit and hydrogen gas (H2) provided by the electrolyzer can be delivered to a methanation unit to produce syngas (CH4) for different applications. The oxygen from the electrolyzer is injected into the combustion chamber to improve the combustion process. Results show that by using 80 units of 1 MW Nordic wind turbine to generate electricity, all of the CO2 in the exhaust gas is converted to syngas. The whole system energy and exergy efficiencies are equal to 16.6% and 16.2%. The highest and lowest energy efficiencies of 85% and 30.1% are related to compressor and steam power plants. The energy and exergy efficiencies of the wind turbine are 30.7% and 11.9%. The system can produce 40920.4 MWh of electricity and 180.5 MWh of cooling. As CO2 is consumed to produce syngas, the proposed system is capable of avoiding a significant amount of 2776 t CO2 emissions while producing 1009.4 t syngas annually. Based on economic analysis, the payback period of the system is 11.2 y, and internal rate of return is found to be 10%, which can prove the viability of the proposed configuration.

The purpose of this study is to investigate an intergration of three cycles consisting of gas, air bottom and steam cycles for electrical power generation and hydrogen production. The configuration of the three cycles is powered by the natural gas that is used by the gas cycle on the top. Then, the exhaust gas of the gas cycle is used by an air cycle at the bottom of the gas cycle and consequently a heat recovery steam generator (HRSG) is driven by the exhaust gas of the air cycle. The purpose of the HRSG cycle is to produce steam to be used in the reformer for the hydrogen production. The energy, exergy, economic and exergoenvironmental analyses of this combined cycle is examined. The results of this study show that addition of air gas cycle to natural gas cycle improves the energy efficiency from 17.2% to 28.% and Payback Period (PP) from 4.72 to 2.92. Whereas, adding HRSG to the whole cycle improves the energy efficiency to 67.6% and Payback Period to 0.41 years. Moreover, this interagation of the cycles improves the Net Present Value (NPV) from 1.13 × 109 to 2.07 × 109 for gas and air cycle, respectively and to 3.89 × 1010 $ by the whole cycle.

This article presents a novel renewable-based multi-generation energy system. The system is based on a double effect absorption chiller, an ejector refrigeration cycle, a proton exchange membrane electrolyzer, an amine-based CO2 capture system, an organic Rankine cycle, and a heater. The proposed integrated system is fueled by a biomass combustor, a photovoltaic thermal solar panels, and a waste heat recovery from a cement plant located in Abyek, Iran. This innovative configuration of energy system can produce electricity, cooling, heating, and hydrogen in summer and winter modes, in addition to removing CO2 from the flue gas of the cement plant. The system is analyzed in energetic, exergetic and thermoeconomic terms. The performance of the system is investigated parametrically by examining the effect of variation of selected key parameters. To perform comprehensive modeling, the system is assessed thermoeconomically through estimating unit cost of each product and total cost rate of the product. Finally, single and multi-objective optimizations are performed by an evolutionary algorithm and illustrated on a Pareto frontier in order to achieve the optimum scheme of the multi-generation system regarding technical and economic viewpoints. According to the results, the studied integrated system produces 17.4 MW and 18.4 MW electricity in summer and winter, 4.1 MW heating power, 1.2 MW cooling power, 5.8 kg/h and 11.3 kg/h hydrogen in summer and winter. Moreover, the system captures 234.1 kg/s CO2 with 90% removal factor from the cement plant. The result of the optimization indicates in winter product cost rate of the Combined Cooling, Heating and Power (CCHP) subsection can reduce 24%. However, in summer for a 0.47% increase in product cost rate, the exergy efficiency is capable of increase by 39%.
