Air
Liquide has many modes of H2 supply, which are
adapted to the specific needs of the Group’s
diverse range of customers. Pipeline networks
supply large customers that consume significant
amounts of H2. H2 cylinders and tube trailers
at 200 bar are used for smaller customers. For
some specific customers, liquid tanks are constructed
onsite and filled regularly by cryogenic liquid
trailers.
Cylinders
For gas
users who need mobility and/or have volume
requirements of less than 5000 m3 per month,
gas cylinders can represent an extremely practical
method of supplying gas.
Gas cylinders are defined by four main characteristics.
State of gas : compressed gas, refrigerated
liquid (CO2, nitrous oxide), dissolved gas (acetylene)
or cryogenic liquids.
Purity of gas :
up to 99.99999 %.
Type
of cylinder: size (volume) and pressure, which
differs from one country to another have been
the focus of special development.

AIR LIQUIDE has for many years been putting
forward innovative
solutions in
the gas cylinder field in order to improve
its safety, economy and ease of use.
Cylinders can be supplied individually
or linked together in groups of 9 or 18
interconnected cylinders, which then empty
as if they were a single container. |
AIR
LIQUIDE carries in-house treatments and
special packaging procedures to guarantee conformity with specifications.
We also undertake regulatory checks and retest cylinders.

Air Liquide has participated over
the last three years in the creation
and commissioning of a number of
service stations—one in Madrid,
in Spain, and one in Luxembourg,
each powering H2 fuel cell buses,
as part of the CUTE (Clean Urban
Transport for Europe) / Hyfleet
project. |

The
third station, built by Japan Air
Gases, a subsidiary of Air Liquide,
in Japan, supplies buses and cars
with H2. Elsewhere, Air Liquide
is operating a test station test
at Sassenage (France) on the Air
Liquide Advanced Technology Division
site, which acts as a test station
and a mobile station and is used
to perform one-off demonstrations
of hydrogen vehicles.
At the same time, Air Liquide is
developing and building commercial
hydrogen stations for oil companies
or motor vehicle manufacturers,
the last example of this being the
BP hydrogen station in Singapore. |
