The most common industrial method of hydrogen synthesis is via steam reforming.   This technology generates hydrogen from methane by reacting it with water over a nickel-alumina catalyst [1].  Catalysis employing the same chemistry is also performed on other hydrocarbons (e.g. naptha, number 2 fuel oil). This process is relatively inefficient due to the high temperature and pressure required. The product gas contains carbon monoxide and carbon dioxide impurities [1].
