Hydrogen is clean because all that is left after combustion is clean water. However, there is one hiccup. Processing hydrogen is extremely difficult. The mere fact that hydrogen molecules are particularly small makes it hard to separate them. In addition, producing lighter fuels requires hydrogen at high pressure and high temperature. This demands a special material, so-called 2¼ chromium steel.  One of the characteristics of this steel is its extreme sensitivity to rupture, therefore, perfect workmanship is required to process it.
