Summary This study proposes a novel multigeneration system consisting of a gas turbine cycle, multi‐effect desalination (MED), mono ethanolamine‐based post‐combustion carbon capture, and a co‐electrolysis unit. The designed multigeneration system aims to produce electricity, freshwater, syngas, and oxygen. This study considers two main configurations, namely base and advanced cases. In addition, the advanced configuration is simulated for three scenarios of carbon utilization and absorption efficiencies of 85%,90%, and 95% in the capture unit. The system is analyzed from energy, environmental, and economic points of view to ascertain the feasibility of each scenario. The scenarios include (i) transferring all captured carbon dioxide to a co‐electrolysis unit, (ii) delivering 30% of captured carbon dioxide to a co‐electrolysis unit and storing the rest, and (iii) storing all captured carbon dioxide. According to the results, the advanced system, compared with the base case, has 26.27% higher energy efficiency and 8.01% higher carbon dioxide capture efficiency besides 42% lower water consumption. The first scenario performs better in oxygen and syngas production (44.46 and 33.51 kg/s). In contrast, the third scenario is the most promising, considering energy and carbon dioxide capture efficiency (83.72% and 76.61%) and net electricity generation (327.97 MW). Moreover, the third scenario demonstrated the best economic feasibility with the prime cost of electricity equal to 0.02 US$/kWh and a period of return of about 1.1 years. The results confirm that the proposed multigeneration system is capable of producing multiple useful and affordable products while minimizing the CO2 emission to the atmosphere.

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.

In this paper, a multigeneration cycle of electricity, cooling, and Bitcoin whose energy source is geothermal, has been subjected to energy, exergy, and economic analyses. The cycle under consideration includes the steam cycle (upstream cycle), the carbon dioxide cycle (downstream cycle), and the liquid–gas line to absorb the heat dissipated by the carbon dioxide cycle. In this cycle, the steam cycle condenser acts as the carbon dioxide cycle evaporator. Part of the electricity generated by this cycle is used to generate Bitcoins. Energy and exergy efficiencies at baseline (excluding Bitcoin production) are 45.8% and 38.1%, respectively. In this cycle, if more power is spent on producing Bitcoin as a product, the energy and exergy efficiencies of the cycle are reduced. Because Bitcoin itself is not valuable in terms of energy and exergy. Considering the average price of Bitcoin during the years 2015–2022 and if 100% of the electricity generated by the system is spent on Bitcoin production, the payback period in 2018, 2021, and 2022 when the price of Bitcoin is equal to $13,412.4, $21,398.8, and $47,743.0, respectively, are less than the baseline. Therefore, the production of Bitcoin with a variety of renewable energies can be considered as a solution. Of course, it should be noted that large changes in the price of Bitcoin can affect the issue of economic benefit.
