An electrochemistry model was developed to analyse the J-V characteristics of a Proton Exchange Membrane (PEM) water electrolyser for hydrogen production. The Butler-Volmer equation and water transport characteristics through electrolyte membrane were employed to simulate the electrode activation overpotential and membrane ohmic overpotential, respectively. The modeling results are found to agr...

A composite cathode based on redox-stable La0.2Sr0.8TiO(3+δ) (LSTO) can perform direct carbon dioxide electrolysis; however, the insufficient electro-catalytic activity limits the electrode performances and current efficiencies. In this work, catalytically active scandium is doped into LSTO to enhance the electro-catalytic activity for CO2 electrolysis. The structures, electronic conductivities...

Abstract—This paper introduces a method to optimal design of a hybrid Wind/Photovoltaic/Fuel cell generation system for a typical domestic load that is not located near the electricity grid. In this configuration the combination of a battery, an electrolyser, and a hydrogen storage tank are used as the energy storage system. The aim of this design is minimization of overall cost of generation s...

This paper presents a model of an energy system for private household extended by lifetime prognosis. The was designed fully covering the year-round demand on basis electricity generated photovoltaic (PV) system, using hybrid storage consisting hydrogen unit and lithium-ion battery. Hydrogen is produced with Proton Exchange Membrane (PEM) electrolyser PV surplus during summer months then stored...

The investment costs of water electrolysis represent one key challenge for the realisation renewable hydrogen-based energy systems. This work presents a technology cost assessment and outlook towards 2030 alkaline electrolysers (AEL) PEM (PEMEL) in MW to GW range taking into consideration effects plant size expected developments. Critical selected data was fitted modified power law describe an ...

This paper proposes a Hybrid Microgrid (HμG) model including distributed generation (DG) and hydrogen-based storage system, controlled through tailored control strategy. The HμG is composed of three DG units, two them supplied by solar wind sources, the latter one based on exploitation theProton Exchange Membrane (PEM) technology. Furthermore, system includes an alkaline electrolyser, which use...
