Industrial hydrogen gas plays a significant role in modern
industry, in sectors ranging from chemical processing to electronics
to food processing.
Approximately 90 per cent of hydrogen used in industrial
applications is produced and consumed on-site in large facilities,
including oil refineries and ammonia synthesis and methanol
synthesis plants. Merchant delivery of either compressed or
liquid hydrogen accounts for the remaining 10 per cent of
the hydrogen market.
In terms of production, approximately 80 per cent of industrial
hydrogen is generated from natural gas and other hydrocarbons
through steam methane reforming (SMR). SMR systems typically
include a reformer to produce a crude hydrogen stream and
a gas purification unit to purify the hydrogen. The remaining
20 per cent of industrial hydrogen is recovered from hydrogen-containing
off-gas streams in oil refineries and chemical plants. Processes
such as electrolysis and ammonia dissociation are also used
for very small-scale applications.
