Powered by Hydrogen

The International Renewable Energy Agency (IRENA) estimate that 3% of the global energy demand is being met by hydrogen, similar to the annual energy consumption of Germany.    

At the end of 2021, only 1% of hydrogen plants were producing renewable or ‘green' hydrogen – that is, the production was powered by a renewable energy source. Currently there is no way for consumers to know the difference between hydrogen produced with fossil fuels, or that which is produced with low carbon power sources, although a global certification project is underway to close this gap.

The Australian Government has set aside AU$2 billion to incentivise the production of renewable hydrogen in Australia (the Hydrogen Headstart program) and has been actively developing a Guarantee of Origin (GO) scheme to measure, track and verify carbon emissions and other attributes of clean energy products. 

Stanwell is driving the development of Queensland's hydrogen industry, particularly through the flagship Central Queensland Hydrogen Project.

How hydrogen works

Renewable or green hydrogen is produced from water using renewable energy via a process called electrolysis.

Electrolysis involves a strong electrical current being passed through purified water. The electric current splits the water into its constituent elements, hydrogen and oxygen. Hydrogen can be used immediately, but it can also be stored in tanks for later use. It can also be converted to liquid form.

When hydrogen reacts with oxygen in the air, it generates heat energy which can power vehicles, ships and industrial facilities. It can also supplement the domestic natural gas supply and be fed through gas turbines to generate electricity.

Electrolysers – the devices that split water into hydrogen and oxygen – can ramp their production up and down to supplement the variable output of renewable energy sources like wind and solar.

Our flagship projects

  • CQ-H2

    The Central Queensland Hydrogen Project (CQ-H2) is a global collaboration involving domestic and international partners from across the hydrogen supply chain who have come together to develop a global-scale renewable hydrogen project near Gladstone in Central Queensland.

    Stanwell is leading the project's Front-End Engineering Design on behalf of the consortium.

    The project will involve development of a hydrogen production facility at Aldoga, near Gladstone, a hydrogen gas pipeline to transport hydrogen to Gladstone Port, a hydrogen liquefaction facility and ship loading facilities at Gladstone Port, and an ammonia production facility at Gladstone Port.

    How does low to zero emissions gas work?

    Natural gas has long been a key energy source for homes, businesses and industry in Queensland, but its future now lies in cleaner alternatives.

    How does hydrogen work?

    Renewable hydrogen is emerging as a key player in the global transition to clean energy, helping to reduce emissions while creating new economic opportunities. But what exactly is hydrogen, and how can it help us achieve a more sustainable future?
