Australia can nonetheless attain its net-zero power objective by 2050, based on BloombergNEF (BNEF), however there is no such thing as a time to waste, with the necessity for vital investments in photo voltaic, wind, and power storage. to remain on observe.

A brand new mannequin from BNEF reveals Australia must quickly decarbonise its electrical energy sector to succeed in a net-zero dedication by 2050, with an funding of AUD 3.56 trillion ($2.4 trillion) wanted by 2030 and renewable power capability ought to develop by 135% to greater than 126 GW.
The newest version of BNEF’s New Energy Outlook report reveals that to remain on observe, Australia’s power combine should change over the following decade, with all coal intermittent and virtually all fuel era which is able to exit the ability system by 2035. Australia will as an alternative depend on a mixture of renewables paired with versatile applied sciences equivalent to batteries and pumped hydro.
Leonard Quong, head of BNEF in Australia, stated there is no such thing as a time to waste in launching renewables on this decade which is crucial to reaching decarbonisation targets.
“Australia’s window to remain on a nicely under two diploma path is closing quick,” he stated. “Rapid transition to a clear electrical energy system based mostly on wind, photo voltaic and storage is important to successfully cut back carbon emissions in keeping with our current decarbonisation targets, however the heavy lifting should be finished this decade … additionally serves as a basis for future emission discount efforts in different sectors of the financial system within the coming years.
In its newest report, BNEF fashions a internet zero state of affairs (NZS), according to 1.75 C of worldwide warming by 2050, and a base-case financial system transition state of affairs (ETS), according to 2.6 C because of warming.
In the NZS’s favored state of affairs, Australia will strongly electrify the ability, transport and development sectors by 2050, driving whole electrical energy demand 2.5 occasions, with photo voltaic and wind installations to comply with of a mixed 290 GW by mid-century. Storage, within the type of batteries and pumped hydro, has elevated from about 3 GW right this moment to greater than 59 GW.
This state of affairs is predicted to require an enormous AUD 3.56 trillion funding, however BNEF says it’s estimated to value solely a further 12% extra in comparison with the baseline ETS however will ship higher ends in net-zero phrases.
BNEF additionally stated Australia would nonetheless face enormous funding necessities to resume and preserve the power sector even with out decarbonisation.
“Australia ought to at all times spend money on its power system, even when it reduces carbon emissions,” stated Caroline Chua, BNEF’s power transition specialist and lead writer of the report. “The problem of attending to internet zero is ensuring capital flows to the precise varieties of applied sciences, on the proper time.”
In addition to ramping up photo voltaic, wind, and power storage, the report additionally highlights the necessity to scale up different key applied sciences equivalent to electrical automobiles and hydrogen to pursue internet zero.
“Emerging applied sciences equivalent to hydrogen, biofuels and carbon seize programs are important for Australia to succeed in internet zero,” stated BNEF Australia Senior Associate Sahaj Sood. “While questions nonetheless stay about their reliability, acceptability, and scalability, if they aren’t accessible, emission reductions should come from elsewhere within the financial system, and certain from dearer options.”
