Hydrogen
ANZIGA members have unique expertise and experience in the production, transportation, storage and application of hydrogen. They are therefore well placed to be a major partner in the mission to a greener energy source and a cleaner future.
Hydrogen is a major industrial gas not only used as a green power source but is utilised across a range of industries. Hydrogen is widely used in the production of bulk chemicals, intermediates and speciality chemicals.
Some uses of hydrogen are:
- Component in welding mixtures
- Metal cutting
- Hydrogenation process for the production of margarine
- Hydrodesulphurisation of fuel
- Due to its small molecules, it is ideal for leak detection when used alongside hydrogen detectors
- Prevents metal oxidation during heat treatment
- Due to its low viscosity and high thermal conductivity, it is extensively used as a coolant gas in power generators
- Fuel cells, eg for fuel cell electric vehicles
- Lifting weather balloons to high altitude
Hydrogen has particular characteristics which must be considered:
- Hydrogen is 14 times lighter than air and therefore dissipates rapidly when released or leaked in open air, but it is not toxic.
- Hydrogen has a wide range of flammable concentrations in air and lower ignition energy than natural gas or gasoline. It can ignite very easily.
Engineering safe hydrogen systems requires special expertise.
ANZIGA members participate and lead the Australian Standards committees responsible for the development and maintenance of standards that cover all aspects of hydrogen across the value chain as an energy carrier are within scope.
This includes the production, storage and handling, measurement, transport, transmission and distribution of hydrogen in its pure form, blended with another fuel gas or via an alternate hydrogen transport vector and use of hydrogen. Also included are end-use applications such as hydrogen refuelling infrastructure and mobility applications, domestic and industrial appliances and power and heat generation.
