Hydrogen production methods include hydrolysis and fossil fuel hydrogen production. Hydrolytic production includes alkaline hydrolysis and pure water electrolysis (PEM). Fossil fuel methods use methanol and natural gas.

An integrated hydrogen production and refueling station consists of hydrogen production, purification, boosting equipment, storage devices, refueling machines, a cold water system, and a control system. On-site hydrogen production saves transportation costs, reduces the size of storage devices, and lowers the operation costs of the refueling station.
