UNSW researchers make green hydrogen cost competitive

Engineers from UNSW Sydney have crunched the numbers on green hydrogen production costs and revealed that Australia is in a prime position to take advantage of the green hydrogen revolution.

In a new paper titled Cell Reports Physical Science, the researchers identified the key factors required to reduce the cost of green hydrogen to become competitive with other methods of producing hydrogen using fossil fuels.

The study authors highlight how different factors affect the cost of producing green hydrogen by electrolysis, using a dedicated solar system and no additional power from the grid.

Without using electricity from the grid, which is predominantly supplied by fossil fuel electricity, the method produces hydrogen with nearly zero emissions. Being grid-free also means such system could be deployed remotely.
