Thermodynamics analysis of a hybrid system based on a combination of hydrogen fueled compressed air energy storage system and water electrolysis hydrogen generator

Knowledge Mapping of Hybrid Solar PV and Wind Energy Standalone Systems: A Bibliometric Analysis

“…Vertical axis wind turbines or bladeless wind turbines could be alternative plans for HPWESS that are operated on buildings or around people since the optional devices have merits like low noise and ease of installation and maintenance compared to HAWT. As for the generator of solar energy, energy and exergy analysis revealed that among all the components, the PV panels have the lowest conversion efficiency in HPWESS, which is far behind others' efficiency [61][62][63][64]. Advanced generators of solar energy that improve the photovoltaic conversion efficiency or use discarded thermal energy of insolation to generate additional power are expected to develop, which will promote the efficiency of the whole power system.…”

Enhanced ethanol oxidation reaction of CoSeO3 by Ni-doping for water electrolysis and an innovative zinc–ethanol–air battery

“…The production of hydrogen is the key bottleneck for hydrogen energy applications, and water electrolysis is currently a research hotspot. 1 Traditional water electrolysis involves two reactions, the Hydrogen Evolution Reaction (HER) and Oxygen Evolution Reaction (OER), among which the slow kinetics of the OER hinders the development of water electrolysis for hydrogen production. 2,3 The complex proton-coupled multi-electron transfer process of the OER leads to a high overpotential required to initiate the reaction.…”

“…3g show that the working voltage decreased by approximately 100 mV at a current density of 10 mA cm À2 , indicating improved electrolysis efficiency with ethanol. 1 H NMR was used to identify ethanol oxidation products in CP measurements. Fig.…”
