What is Hydrogen

Hydrogen Energy Australia

Hydrogen is a natural gas and a clean alternative to methane accounting for 75% of all mass in the universe, making it one of the galaxy’s most abundant resources. This remarkable hydrogen energy source can be found in water, animals, plants, and even humans, as it is present in every molecule of all living things.

Hydrogen is a rare gas that can be produced using renewable energy sources such as solar, wind, and biogas, which involves the decomposition of organic matter such as food scraps or wood waste. The advancement of hydrogen capabilities has made it the preferred solution for countries and businesses committing to net-zero emissions by 2050.

Currently, hydrogen energy in Australia is seeing unprecedented investment from both the private and government sectors. This momentum will continue to grow as Liberty Energy Capital works with its partners to create hydrogen solutions that will lead to a carbon-free economy.

Emissions Generating Hydrogen

  • Grey, brown and blue hydrogen are known as emissions generating hydrogen.
  • Grey is produced using non-renewable natural gas and releases carbon emissions into the atmosphere.
  • Brown hydrogen is made by burning coal, which generates high levels of carbon dioxide pollutants.
  • Blue hydrogen is produced through steam methane reforming, resulting in a chemical reaction where hydrogen and carbon monoxide are formed. This method is almost emissions-free, as a device is used to capture the hydrogen.

Net-zero Carbon Hydrogen

  • Green, emerald and turquoise hydrogen are known as zero-emissions hydrogen due to the way they are produced.
  • Electrolyser technology creates green hydrogen, which uses renewable electricity to split water into hydrogen and oxygen.
  • Emerald hydrogen involves a method for converting waste and feedstock into gas. The process requires the waste to be ignited and then retracted for the air injection point to gasify the fuel.
  • Turquoise hydrogen uses a plasma arc or a pyrolysis method to split methane into hydrogen and solid carbon.
