The United States produces nine million tons of hydrogen per year
is one of over 20 hydrogen production facilities supplying 1.2 billion standard cubic feet per day
sometimes referred to as steam methane reforming
The U.S has an annual hydrogen production of 9 million tons approximately.
With no steam export the theoretical energy consumption is
300 BTU/scf H2 on LHV (lower heating value) basis. The
industrial value for natural gas based plants is about 320 BTU/scf
H2 corresponding to 94% of the theoretical efficiency. At
locations with high natural gas prices, the energy efficiency
becomes critical. For a natural gas price of 4 USD/MM BTU, the
feedstock and utility costs makes about 65% of total operating
costs.
