Queensland says it can double the world's green hydrogen production capacity with a single project. 

Queensland Premier Annastacia Palaszczuk has announced plans to build the world's largest green energy hydrogen manufacturing facility in Central Queensland.

The project has been handed to Fortescue Future Industries (FFI), whose founder - mining billionaire Andrew "Twiggy" Forrest - says it will be carried out in six phases. 

The first step is a $115 million manufacturing facility to be built in Aldoga, west of Gladstone. He says this project alone will double the world's green hydrogen production capacity and bring thousands of jobs to Queensland’s energy industry.

The facility will manufacture green energy infrastructure and equipment, including electrolysers, cabling and wind turbines to create green hydrogen.

The first stage is expected to produce 2 gigawatts of hydrogen electrolysers each year, which split hydrogen from water, producing emission-free energy.

The world currently produces one gigawatt of electrolysers per year.

The proponents of the plan say that Traditional Owners in the Gladstone region could be offered secure work in the industry, and some training could be set up in local high schools.
