The emission of greenhouse gases from fossil fuels is the main environmental impact of energy resources. Moving toward the use of renewable energy resources is the only solution to tackle these problems. In this paper, a configuration of the hybrid biomass and geothermal energy resource is examined for cooling and electricity generation. In this study, water as a geothermal working fluid is heated up due to combustion of syngas produced in a digester and produce power in a steam turbine. So, the remaining heat of this geofluid runs an absorption chiller for cooling production. The results reveal that the energy and exergy efficiencies of this proposed cycle are 30.8% and 15.5%, respectively. Moreover, the economic analysis of this cycle concludes that the payback period is 2.8 years and the simple payback period for this configuration is 2.6 years. Moreover, the highest exergy destruction rate of 52.4% belongs to the absorption refrigeration cycle. Whereas the lowest exergy destruction of the steam line is the lowest value of 17.4%.

“…Ozturk and Dincer 9 studied a combined cycle geothermal power plant model that produces hydrogen for blending into natural gas to increase energy and exergy efficiencies (with the developed model, energy and exergy efficiencies were obtained as 46.8% and 77.9%, respectively). Heidarnejad et al 10 investigated a biomass assisted geothermal power plant that also produces fresh water. The aim of that study is to increase the efficiency of geothermal power plants with low enthalpy by integrating biomass power plants.…”

Summary This study investigates the integration of thermoelectric generators (TEGs) into geothermal power plants to harvest energy from the waste heat and possibly, as a result, to increase the electrical energy generation of geothermal power plants. For this purpose, a model of a geothermal power plant‐TEG hybrid system has been designed and implemented as an experimental setup. In addition, the optimized layout configuration of TEGs is obtained by using Matlab & Simulink for 48 pieces of the TEGs. A parametric energy analysis is conducted by varying the temperature of the reinjected geothermal brine and the inlet temperature of the cooling water, since TEGs are planned, so they can be employed between the pipelines of the cooling water and the reinjected geothermal brine. The effects that this has on the performance of the organic Rankine cycle (ORC) and the TEGs are then determined. It was found that the power output of the TEGs increases with the rise in temperature of the reinjected geothermal brine, but the net power of the ORC decreases. For the maximum net power output of the ORC, which is 217.6 kW, TEGs are able to produce 43.42 W for the temperature difference of 41.98°C that corresponds to this status. Therefore, TEGs must be used with lower power outputs to achieve more energy production from this hybrid energy system. For the high inlet temperature values of cooling water, the net power of the ORC decreases, and the power output of the TEGs also goes down. TEGs are able to produce 84.29 W for the temperature difference of 60.6°C for the ORC's maximum net power output of 260 kW. Therefore, it is clear that using TEGs in the power plant for low inlet temperature values of cooling water can be considered. In conclusion, this study demonstrates that waste thermal energy in reinjected geothermal brine can be harvested through TEGs, and this energy could be used to feed the electrical equipment of the power plant with low energy consumptions such as lighting, sensors, instrumentation, and control systems. However, TEGs should be used carefully, since they may affect the overall performance of the geothermal power plant.

“…With the increasing demand for electric power and awareness for environment protection, the development of power generation technologies has been moving to the direction of high power output and clean production [1][2][3][4][5]. Power generation by using clean energy sources, such as solar energy, wind energy and geothermal energy et al are more environmentally-friendly than fossil fuel, and they have been becoming more and more important [6][7][8][9][10]. However, clean energy sources are highly depended on the local natural conditions and local natural resources.…”

The mechanism of performance degradation of a natural gas combined cycle (NGCC) power plant under high ambient temperature is studied by analysing the performance characteristics and thermal properties of the working fluids. Real operating data under typical seasonal conditions are collected and studied. The results reveal that the power output of the NGCC system decreases by 22.6 %, and the energy efficiency decreases from 57.28 % to 56.3 % when the ambient temperature increases from 5-35?C. GT total power output and ST power output decrease by 17.0 % and 16.2 %, respectively, as ambient temperature increases from 5-35 0C. The enthalpy difference of the flue gas between the turbine inlet and outlet change slightly with varying ambient temperature. The fuel and air input decrease by 16.0 % and 16.2 %, respectively, as ambient temperature increases from 5-35?C. By analysing the calculated results, the decrement in air and fuel input d is considered as the immediate cause of system power output reduction. The proportion of power consumed by AC reaches 50.4 % at 35?C. This is considered to be caused by air compressor idle.
