Abstract In this article, a novel multi-generation plant is addressed and assessed from the energy, exergy, exergoenvironmental exergoeconomic points of view. The composed two main units: one unit for energy production another carbon capture methanol synthesis. Biomass fuel, solar seawater are nutrients in plant. Steam, Brayton, organic Rankine Kalina cycles have been employed to generate electricity. A linear Fresnel collector-driven farm considered as an auxiliary heat source. addition, integrated desalination based on multi-effect unit, microbial fuel cell reverse osmosis has installed proposed structure offered designed under new configuration layout that had not reported publications. From outcomes, can produce 69.6 MW net electricity, 0.53 kg/s methanol, 0.81 oxygen gas, 73.8 fresh water ~0.015 hydrogen gas. Under such performance, be 51.72 27.5% efficient view respectively. Further, total cost rate environmental impact ~3378 US$/h 294.1 mPts/s, comparative analysis developed exhibit superiority planned five-objective optimization also achieve optimum design data outcomes

The thermodynamic analysis of a geothermal-based integrated energy system to produce liquid hydrogen, cooling, hot water, and power was presented in this study. investigated made geothermal subsystems, modified organic Rankine cycle (ORC), PEM electrolyzer, hydrogen storage source. Different fluids including refrigerants R113, R123, R134a were increase the performance. Analysis showed that best fluid is R123 because it helps performance system. authors employed Design-Expert software RSM for optimum results purposes, objective functions chosen be exergy efficiency (EE) cost rate (CR). Following introduction design variables, mass flow input evaporator, temperature heat recovery vapor generator, turbine efficiency, temperature, evaporator pinch point pump their impact on system's investigated. optimal values EE CR ultimately found 43.91% 45.12 $/h, respectively. Also, research, seven regions within Canada launch proposed studied cities Victoria, Vancouver, Regina, St. John's, Dawson Creek, Whitehorse, Port Alberni. Finally, Regina superior electricity production at reasonable area. environmental city could help expand 5 hectares green space by producing 4993.03 MWh one year. findings indicated implementing suggested would prevent 1018.6 tons CO2/MWh from being emitted into environment yearly, only chipping 24445.9 $/ton CO2 per

As part of the transition to a sustainable future, energy-efficient buildings are needed secure users' comfort and lower built environment's energy footprint associated emissions. This article presents novel, realistic affordable solution minimize smart building systems enable higher renewable use in sector. For this, an intelligent system is being developed using rule-based automation approach that considers thermal comfort, prices, meteorological data, primary use. In order installation cost environmental footprint, batteries not used, heat pump's size decreased via component integration. Also, different resources effectively hybridized photovoltaic panels innovative biomass heater increase share energy, enhance reliability, shave peak load. feasibility, suggested framework assessed from techno-economic standpoints for 100 residential apartments Stockholm, Sweden. Our results show 70.8 MWh electricity transferred local grid, remaining 111.5 used supply building's needs power electrically-driven components. The meets more than 65% space heating demand, mainly at low solar high illustrating value integration strategies reduce system's dependability on grid. further reveal most purchases during cloudy days nights repaid through sale excess production warmer hours, with bidirectional connection monthly less 140 $/MWh years. can be held due exclusion minimizing pump size. proposed has emission index 11.9 kgCO2/MWh carbon dioxide emissions by 70 TCO2/year compared Swedish mix.

Replacing fossil fuel-based systems with renewable energy resources is a method to enhance the performance of layout and reduce environmental pollution. The gas turbine cycle (GTC) one main sources consuming natural (NG) in combustion chamber (CC). In present study, theoretical 500 kW CC-based improved by replacing NG CC solar power tower (SPT) converting it into multi-generation system. waste heat recovery GTC done hot water unit an inverse Brayton (IBC), then rejection stage IBC exhausted system recovered thermoelectric generator (TEG) absorption chiller. Afterwards, produced TEG fed proton exchange membrane electrolyzer reverse osmosis desalination for hydrogen potable outputs. 4E optimization shows that exergy efficiencies (Configuration 1) SPT-based 2) are equal 37.2% 9.12%, respectively. However, economic Configuration 2 better. this case, total cost rate 142.1 $/h 15.14 $/GJ comparison 145.5 31.58 1. addition, fuel consumption emissions zero, while make up 54.76%
