Billionaire’s blunt warning to Andrew Forrest over hydrogen
Liam Bartlett
An MIT-trained renewable energy
entrepreneur believes Fortescue’s plan to use renewable energy to make
hydrogen will not be as cost-effective as using wind and solar.
The warning from Rewiring Australia
founder Dr Saul Griffith comes as fellow billionaires squabble over
what is the right renewable path for Australian energy.
Dr Griffith says Forrest’s plan to use
solar power to create hydrogen from water and use it to fuel cars and
steel making isn’t feasible.
“The fundamental challenge is, green
hydrogen has to start with electricity, and hydrogen is just a battery
… so you need three of four amounts of electrical energy for every one
unit of hydrogen, so no matter how you look at it, it will be three of
four times more expensive than just using the electricity directly,”
he told Liam Bartlett on 6PR Mornings.
