Abstract
Although alkaline water electrolysis (AWE) is a highly mature technology for hydrogen production, its potential is hindered by relatively low efficiencies at high current densities. On the other hand, to conform with “RePowerEU” directives, coupling electrolyzers with new renewable energy sources (RES) is highly demanded. However, integrating fluctuating RES poses challenges for the AWE due to increasing gas impurity as the current density decreases. Herein, we revised the most promising recent developments in materials, cell design, and system integration aimed at conquering the aforementioned challenges. It is shown that the implementation of advanced components and control strategies, e.g. electrolyte management, is vital to enhance the efficiency at high current densities and expand the load range of operation by maintaining the high gas purity.
期刊介绍:
The development of the Current Opinion journals stemmed from the acknowledgment of the growing challenge for specialists to stay abreast of the expanding volume of information within their field. In Current Opinion in Electrochemistry, they help the reader by providing in a systematic manner:
1.The views of experts on current advances in electrochemistry in a clear and readable form.
2.Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications.
In the realm of electrochemistry, the subject is divided into 12 themed sections, with each section undergoing an annual review cycle:
• Bioelectrochemistry • Electrocatalysis • Electrochemical Materials and Engineering • Energy Storage: Batteries and Supercapacitors • Energy Transformation • Environmental Electrochemistry • Fundamental & Theoretical Electrochemistry • Innovative Methods in Electrochemistry • Organic & Molecular Electrochemistry • Physical & Nano-Electrochemistry • Sensors & Bio-sensors •
