Abstract

When powered by renewable energy source, efficient and low-cost water electrolysis may be a sustainable way to produce green H2, making it competitive with respect to grey H2 from fossil fuels. In the present article, the urgency of improving the efficiency of the water electrolysis process has been highlighted, analyzing the recent progress in the scientific field. Anion Exchange Membrane Water Electrolysis (AEMWE) has been indicated as a new generation technique where the advantages of Alkaline (AWE) and Proton Exchange Membrane (PEM) Water Electrolysis (WE) could be joined. The combination of bibliometric and bibliographic analyses has been used to evaluate the temporal evolution of the research, and to identify the topics of recent investigation, and possible future developments.
