Indeed, as I've indicated, the two main government policies are Hydrogen Headstart and the production tax credit, which is only paid on production. No payments have been made, because none has been produced. I will get the honourable member more information about the hydrogen hubs because some are proceeding and some have not proceeded. I will provide the member with that update.

On green hydrogen: it has been the case that governments have invested in green hydrogen—for example, my predecessor, as Minister for Energy, said of green hydrogen, which is made from renewables:

… we expect to be getting down to the $2 mark in the 2030s. So we're investing heavily in this.

The member for Hume said that when he had my job. So green hydrogen has received support from both governments. That is the case. I table the eight occasions in which the member for Hume said that hydrogen could boost GDP by 2050, which is exactly what I said, which is what the opposition has criticised me for.
