<div class="htmlview paragraph">Hydrogen is the most plentiful gas in the universe. However hydrogen never occurs naturally, always combines with other elements such as oxygen and carbon [<span class="xref">1</span>]. Hydrogen is the ultimate clean energy carrier once it is separated from other elements [<span class="xref">11</span>]. Moreover hydrogen can easily be generated from renewable energy sources. Hydrogen is also nonpolluting, and forms water as a harmless byproduct during the oxidation process.</div> <div class="htmlview paragraph">Safe practices in the production, storage, distribution, and use of hydrogen are essential components of a hydrogen economy [<span class="xref">2</span>]. A catastrophic failure in any hydrogen project could irreparably damage the entire transition strategy. The safety program element delineates the steps that the hydrogen, fuel cells &amp; infrastructure technologies program shall ensure that all projects are performed in a safe manner.</div>
