Use of hydrogen as energy carrier is the most promising solution to address the energy and environment issues and to meet future energy needs. Energy systems based on hydrogen fuel cells are characterised by high efficiency and power density and are presently used in many stationary and mobile applications . Main issue that hinders further implementation of hydrogen fuel cell technologies is in the need of a compact, safe, and efficient hydrogen storage. Along with various methods of reversible hydrogen storage based on physical processes (compression, liquefaction) and the use of hydrogen storage materials (high-surface area adsorbents, hydrides, liquid organic hydrogen carriers, etc.) , special attention has been recently paid to on-site (or on-board) hydrogen generation by the hydrolysis of various lightweight materials like ammonia borane , sodium borohydride , aluminium , magnesium and magnesium alloys , magnesium hydride , and so on. These materials can undergo hydrolysis at near-ambient conditions, in alkaline, acidic, or neutral medium, frequently, at presence of a catalyst. Recent R&D activities in the field of hydrogen generation by hydrolysis of light metals and hydrides have been presented in Chapter I of a monograph jointly contributed by the researchers from Institute for Energy Technology / Norway and National Academy of Sciences of Ukraine ; a comprehensive review on the topic (289 references) has been recently published by Ouyang et al. .
