The Upper Hunter could be home to a manufacturing plant producing hydrogen-based energy modules that can be retrofitted to large industries, including coal-fired power stations.
Central Coast-based technology company Star Scientific has created a Hydrogen Energy Release Optimiser (HERO) - a unique catalyst that can allow hydrogen to achieve its full potential as a sustainable energy source.
In test runs Star Scientific has generated over 700 degrees celsius in just over three minutes.
"It's a couple of years away before you see something installed but it's definitely been proved, it works, there is no issue with the tech. It's just now how do you manufacture it," chairman Andrew Horvath said.
Applications include food processing, green steel manufacturing, desalination and power stations.
