Current Hydrogen Market Potential

H2 First Fuels is positioned to take a key supply role and market share for
zero emission low cost hydrogen to the following industries,
currently worth in excess of £70 billion annually:

OIL REFINING

Large quantities of hydrogen are needed in the petroleum industry
Hydrogen is used to process (“upgrade”) crude oil into refined fuels, such as gasoline and diesel,
and for removing contaminants, such as sulphur, from these fuels

Hydrogenation

H2 is used as a hydrogenating agent,
particularly in increasing the level of saturation
of unsaturated fats and oils (found in items such as margarine)

Methanol Production

Methanol, also known as Methyl Alcohol, is produced
in a catalytic process using H2, CO2, and CO.
It is used as an antifreeze, a solvent, a denaturant for industrial ethanol,
a base product for plastics and paints, and automotive and camping fuels.
It is also used in the production of biodiesel.

Chemical industries

Hydrogen is used for the production of Ammonia
It is used to make chemicals such as hydrochloric acid,
and as a reduction agent for metallic ores.

Physics & Engineering

Hydrogen is used in physics and engineering for a number or applications:
It is used as a shielding gas in welding methods such as atomic hydrogen welding. 
Hydrogen is used as the rotor coolant in electrical generators at power stations, because it has the highest thermal conductivity of any gas.
Liquid hydrogen is used in cryogenic research, including superconductivity studies.
In more recent applications, hydrogen is used pure or mixed with nitrogen (sometimes called forming gas) as a tracer gas for minute leak detection.
Applications can be found in the automotive, chemical, power generation, aerospace, and telecommunications industries.
Hydrogen is an authorized food additive (E 949) that allows food package leak testing among other anti-oxidizing properties.

Semiconductors

Hydrogen is employed to saturate broken ("dangling") bonds of amorphous silicon
and amorphous carbon to help stabilize material properties. It is also a potential
electron donor in various oxide materials, including ZnO, SnO2, CdO, MgO, ZrO2,
HfO2, La2O3, Y2O3, TiO2, SrTiO3, LaAlO3, SiO2, Al2O3, ZrSiO4, HfSiO4, and SrZrO3.
