“…This challenging concept envisages the generation of hydrogen and oxygen during charge (or the storage of energy) and the recombination back to water during discharge (or the release of stored energy) in a single cell. Despite an extensive literature on catalysts [17,166], at present, the energy efficiency is very poor, certainly <40%. Significant improvements are only probable when high performance alkaline water electrolysers have been achieved.…”

“…Hence it seems timely to review the advances in alkaline zero gap technology resulting from the recent activity targeted towards upgrading water electrolysis technology. Particularly within energy storage, an attractive concept is the regenerative fuel cell [16,17] with the capability for the production of hydrogen and its conversion back to energy within a single cell; this of course requires an electrode composition and structure allowing energy efficient formation and consumption of both O 2 and H 2 .…”

“…It seems that improving the low-temperature alkaline water electrolysis technology, to increase its efficiency, is still a more realistic solution for large-scale hydrogen production in the near future. 154 For the widespread commercial application of alkaline water electrolysis, current research trends are particularly focusing on the electrodes, electrolytes, ionic transport, and bubble formation.…”

Recebido em 13/12/12; aceito em 28/5/13; publicado na web em 17/7/13Water 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, modern technologies for hydrogen production by water electrolysis have been investigated. In this article, the electrochemical fundamentals of alkaline water electrolysis are explained and the main process constraints (e.g., electrical, reaction, and transport) are analyzed. The historical background of water electrolysis is described, different technologies are compared, and main research needs for the development of water electrolysis technologies are discussed.

“…The number of publications per year in this cluster has recently increased. Regenerative fuel cells (RFC) are the topic of cluster II-C, which can be utilized as both water electrolyzers and fuel cells [43][44][45]. RFC can reduce the total components and weights of the power generator/accumulator, which is beneficial for some applications, such as use in a space shuttle.…”

Abstract:Water electrolysis for hydrogen production has received increasing attention, especially for accumulating renewable energy. Here, we comprehensively reviewed all water electrolysis research areas through computational analysis, using a citation network to objectively detect emerging technologies and provide interdisciplinary data for forecasting trends. The results show that all research areas increase their publication counts per year, and the following two areas are particularly increasing in terms of number of publications: "microbial electrolysis" and "catalysts in an alkaline water electrolyzer (AWE) and in a polymer electrolyte membrane water electrolyzer (PEME).". Other research areas, such as AWE and PEME systems, solid oxide electrolysis, and the whole renewable energy system, have recently received several review papers, although papers that focus on specific technologies and are cited frequently have not been published within the citation network. This indicates that these areas receive attention, but there are no novel technologies that are the center of the citation network. Emerging technologies detected within these research areas are presented in this review. Furthermore, a comparison with fuel cell research is conducted because water electrolysis is the reverse reaction to fuel cells, and similar technologies are employed in both areas. Technologies that are not transferred between fuel cells and water electrolysis are introduced, and future water electrolysis trends are discussed.
