Asking Google for different applications of electrolysis, interesting results can be noticed: electrolysis and hair removal - about 284 000 000 web pages, water electrolysis - about 7 440 000 web pages and industrial electrolysis - about 2 540 000 results. In this book three most important applications of technological electrolysis are discussed - water electrolysis (hydrogen production), industrial electrolysis and environmental electrolysis. Authors of the chapters are recognized specialists in their respective research fields and the presented material is not only from reviews and literature sources, but also original results. We hope that the reader will find useful information in the chapters of this book and are certain that the science can reveal unexpected discoveries even tomorrow, if current progress is at hand or on a shelf.

Renewable energies such as solar, hydro or wind power are abundant in principle but subject to strong fluctuations. Therefore, development of new technologies for storage of these renewable energies is of special interest. Electrochemical technologies are ideal candidates for the use of excess current; consequently, an increased electrification of chemical processes is expected. In this respect, there are different pathways to utilize excess current electrochemically. Perhaps the most accepted and discussed solutions involve intermediate energy storage in either chemical energy carriers (such as hydrogen via water electrolysis) or electrochemical energy storage devices (like batteries). Additionally, excess current can put to other uses, such for solutions to environmental issues or for construction purposes, rather than being stored for later use.
