About 95% of Hydrogen we use today comes from processing natural gas. The remainder is produced using electrolysis – a process that splits water into its individual components, Hydrogen and oxygen. Some of the specific technologies used to produce Hydrogen include:
Steam reforming converts methane (and other hydrocarbons in natural gas) into Hydrogen and carbon monoxide by reaction with steam over nickel catalyst. The carbon separated from the Hydrogen in the reforming process may be captured and sequestered to avoid damage to the environment. Electrolysis uses direct electrical current to split water into Hydrogen at the negative electrode and oxygen at the positive electrode.
