Hydrogen Production by Alkaline Water Electrolysis
Water electrolysis is one of the simplest methods used for hydrogen production. It has the advantage of being able to produce hydrogen using only renewable energy. To expand the use of water electrolysis, it is mandatory to reduce energy consumption, cost, and maintenance of current electrolyzers, and, on the other hand, to increase their efficiency, durability, and safety. In this study, moder...
متن کاملEconomic Analysis of Improved Alkaline Water Electrolysis
Alkaline water electrolysis (AWE) is a mature hydrogen production technology and there exists a range of economic assessments for available technologies. For advanced AWEs, which may be based on novel polymer-based membrane concepts, it is of prime importance that development comes along with new configurations and technical and economic key process parameters for AWE that might be of interest ...
متن کاملSeparating hydrogen and oxygen evolution in alkaline water electrolysis using nickel hydroxide
Low-cost alkaline water electrolysis has been considered a sustainable approach to producing hydrogen using renewable energy inputs, but preventing hydrogen/oxygen mixing and efficiently using the instable renewable energy are challenging. Here, using nickel hydroxide as a redox mediator, we decouple the hydrogen and oxygen production in alkaline water electrolysis, which overcomes the gas-mixi...
متن کاملThermodynamics aspect of high pressure hydrogen production by water electrolysis
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...
متن کاملEffect of Morphology of Co3O4 for Oxygen Evolution Reaction in Alkaline Water Electrolysis
In this paper, three different morphological Co3O4 electrodes for oxygen evolution reaction (OER) have been synthesized. By comparing the three morphologies of Co3O4, the electrocatalytic properties show that the urchin-like spheres of Co3O4 electrode has relative low overpotential and good electrocatalysis stability, indicating that the structure of urchin-like Co3O4 spheres exhibit an easy OE...
