| description | <p dir="ltr">Electric vehicles expansion is accelerating rapidly due to e-mobility’s massive contribution in reducing fossil fuel consumption and CO<sub>2</sub> emissions. Fulfilling the charging requirements of millions of electrical vehicles from the grid would overload the network and introduce substantial burden on the power sector. This study proposes, and thermodynamically assesses, a grid-independent and renewable energy-based, stand-alone electrical vehicle charging station consisting of CPV/T, wind turbine and biomass combustion-based steam Rankine cycle plant. Hydrogen and ammonia-based fuel cells are integrated in the design along with electrochemical, chemical and thermal storage units to ensure uninterrupted charging services during night times and unfavorable weather conditions. Since the proposed design is suggested for use in the State of Qatar, which is located in a hot region, an absorption cooling system is incorporated to cool the produced NH<sub>3</sub> gas and convert it into liquid phase for optimal storage purposes and to maintain the operating temperature of the battery system within the allowable limits. The thermodynamic analysis followed in this study is based on writing the balance equations for mass, energy, entropy and exergy for the system’s components along with their energy and exergy efficiency equations. The results show that the energy generated from renewable energy sources and fuel cells are sufficient to fast-charge 80 electrical vehicles daily. The energy efficiencies of H<sub>2</sub> fuel cell, NH<sub>3</sub> fuel cell, CPV/T, wind turbine and energetic COP of the absorption cooling system are found to be 77%, 72%, 45%, 43% and 0.72, respectively. The exergy efficiency of CPV/T and the exergetic COP of the absorption cooling system are found to be 37% and 0.19, respectively. The overall energy and exergy efficiencies of the proposed integrated system are found to be 45% and 19%, respectively</p><h2>Other Information</h2><p dir="ltr">Published in: Energy Reports<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.egyr.2020.07.022" target="_blank">https://dx.doi.org/10.1016/j.egyr.2020.07.022</a></p> |
