Steam reforming is a method of producing hydrogen. At high temperatures (700 – 1100 °C), steam reacts with methane to yield carbon monoxide and hydrogen.
- CH4 + H2O → CO + 3 H2
Steam reforming of natural gas is the most common method of producing commercial bulk hydrogen. According to Crabtree, et al (as cited in "References"), steam reforming is also the least expensive method. The United States produce through steam reforming of natural gas nearly all of the nine megatons of hyrdogen they produce per year (Crabtree, et al).
