A generic integrated configuration-size optimisation formulation for design of hybrid renewable energy systems (HRES) is presented in this paper. This allows identifying the optimum configuration a given site and size each component that by solving only one problem. Single multiobjective case studies are defined both on-grid standalone using wind turbine, PV panel, battery bank, fuel cell, elec...

Hydrogen can be produced from water electrolysis which can operate at atmospheric pressure or high pressure. Today’s industry including vehicle one, devotes efforts to produce high pressure hydrogen by using pressurized electrolyser. The purpose of this work is to estimate the ideal electrical energy needed for high pressure hydrogen under high pressure water electrolysis conditions. Calculatio...

Since the beginning of the twenty-first century the limitations of the fossil age with regard to the continuing growth of energy demand, the peaking mining rate of oil, the growing impact of CO2 emissions on the environment and the dependency of the economy in the industrialized world on the availability of fossil fuels became very obvious. A major change in the energy economy from fossil energ...

The deployment of wind energy is constrained by wind uncontrollability, which poses operational problems on the electricity supply system at high penetration levels, lessening the value of wind-generated electricity to a significant extent. This paper studies the viability of hydrogen production via electrolysis using wind power that cannot be easily accommodated on the system. The potential be...

A battolyser is a combined battery electrolyser in one unit. It based on flow technology and can be adapted to produce hydrogen at lower efficiency than an but without the need for rare expensive materials. This paper presents method of determining if connected wind farm makes economic sense stochastic modelling. range cost data operational scenarios are used establish impact NPV LCOE adding fa...

This study deals with the preparation and characterisation of catalyst-coated membranes for an alkaline water electrolysis process. For this purpose, a chloromethylated anion-selective block copolymer styrene-ethylene-butylene-styrene 1,4-diazabicyclo[2.2.2]octane functional groups was used both as polymer electrolyte membrane ionomer binder. Non-PGM catalysts (platinum group metals), specifica...

Reversible operation of a microtubular solid oxide fuel cell SOFC with high electrochemical efficiency is reported. These devices can ideally produce hydrogen from electricity and steam solid oxide electrolyser SOE and then use the stored hydrogen to generate electricity and heat SOFC , acting as a storage device for the electrical energy. A fuel-electrode-supported Ni–yttriastabilized zirconia...
