The physical properties of hydrogen make it an important potential candidate to substitute fossil fuels in the next energy economy. Hydrogen can be produced via traditional and novel technologies applied in chemical and electrochemical processes. However, being the smallest molecule of all, hydrogen poses serious challenges to the components of its storage and transport systems. For this reason the materials of the pipes and the valves must be carefully selected, while the joints and the connections need to be sealed properly to avoid problems of degradation and leakage.
