This article presents an experimental study where two different modules are integrated, i.e. a reverse osmosis (RO) module, and a nanofiltration (NF) module, for brackish water desalination unit. Photovoltaic (PV) panels power the setup. The performance for each of the modules was evaluated separately. Then both modules were integrated together, either in series or in parallel. The performance ...

The increment integration of renewable distributed energies means the desired operation of the electric power system will significantly depend on the performance of primary energy. In this order, an integrated approach for mutual interaction between the electricity and natural gas systems has been considered for the purpose of ensuring optimal energy exchanging between the electric power system...

Current solar energy harvest and storage are so far realized by independent technologies (such as solar cell and batteries), by which only a fraction of solar energy is utilized. It is highly desirable to improve the utilization efficiency of solar energy. Here, we construct an integrated photoelectrochemical device with simultaneous supercapacitor and hydrogen evolution functions based on TiO(...

In this study, a new proposed multi-generation system as a promising integrated energy conversion system is studied, and its performance is investigated thermodynamically. The system equipped with parabolic trough collectors and biomass combustor to generate electricity, heating and cooling loads, hydrogen and potable water. A double effect absorption chiller to provide cooling demand, a proton...

Technologically important small band gap (<2 eV) semiconductors must be stabilized against corrosion or passivation in aqueous electrolytes before they can be used as photoelectrodes that directly produce fuels from sunlight. In addition, incorporation of electrocatalysts on the surface of the photoelectrodes is required for efficient oxidation of H2O to O2(g) and reduction of H2O or H2O and CO...

The paper mainly deals with the match of solar refrigeration, i.e., solar/natural gas-driven absorption chiller (SNGDAC), solar vapor compression–absorption integrated refrigeration system with parallel configuration (SVCAIRSPC), and solar absorption-subcooled compression hybrid cooling system (SASCHCS), and building cooling based on the exergoeconomics. Three types of building cooling are cons...

In this work, the solar-thermal-chemical integrated design for a methane dry reforming reactor with cavity-type solar absorption was numerically performed. Combined multiphysical model, gradient optimization algorithm used to find optimal radiation flux distribution fixed total incident energy maximizing overall hydrogen yield, defined as ratio of molar flow exported imported methane, which can...

In the recent times, the use of solar energy for the refrigeration purpose has been increasing day by day. Generally, solar used for cooling purpose has proposed many advantageous features in the refrigeration field. The cooling path is basically depends on the amount of solar radiation. The more amount of solar radiation directly increases the C.O.P. of the system. In this research paper, the ...
