Australia news live: premier rules out ‘risky, toxic’ nuclear energy for Victoria after Coalition names proposed sites for reactors

"Peter Dutton has called a press conference for 10am, so it is all official – nuclear is go.

The Coalition teleconference meeting has wrapped up, and the seven sites have been named and it is as we thought: Collie in Western Australia, Mt Piper and Liddell in New South Wales, Callide and Tarong in Queensland, Northern Energy in South Australia and Loy Yang in Victoria."

"There are already issues being identified with the sites – first, the sites would need to be purchased from private operators. There will need to be some pretty major changes to legislation, both state and federally. The Queensland LNP, as recently as yesterday, said it would not lift the nuclear ban for the state, which is a problem given two Queensland reactor sites have been identified by Dutton’s team.

Tarong in Queensland is a particular issue as it doesn’t have a secure water source. In 2006, then-premier Peter Beattie had to propose a waste water pipeline as a last ditch measure to save the plant during a drought."

    That source doesn’t have a link to their paper that works.

    But based on what was stated just in your link, they say if we build enough storage then we wouldn’t need any baseload generation, which is technically correct.

    In particular, they’re relying on hydro and gas storage.

    (specifically renewable gas and not natural gas, because natural gas is still bad)

    But as far as I know we can’t build anywhere near enough hydro in Australia. Gas storage could technically work, but you’d have to build a ludicrous and economically infeasible amount of gas storage, or pump it into empty spaces underground (but I don’t think we have enough of those in Australia either).

    I’m under the impression that modern nuclear plants as baseload production would still be cheaper than the renewable gas storage we would need to maintain power.

    Do you have a working link to the original paper or a study into how much renewable gas storage we’d require and the costs associated with it?

      But as far as I know we can’t build anywhere near enough hydro in Australia.

      https://www.aph.gov.au/About_Parliament/Parliamentary_Departments/Parliamentary_Library/pubs/rp/rp2021/AustralianElectricityOptionsPumpedHydro

      A study at the Australian National University (ANU) identified about 3,000 low-cost potential sites around Australia with head typically better than 300 metres and storage larger than one gigalitre (see Figure 3). The sites identified have a combined energy storage potential of around 163,000 GWh. To put this into perspective, a transition to a 100% renewable electricity system would need 450 GWh of PHES storage. The potential pumped hydro energy storage resource is almost 300 times more than required. Developers can afford to be very selective since only about 20 sites (the best 0.1% of sites) would be required to support 100% renewable electricity generation.

      Emphasis mine.

        Okay that’s good, spaces for hydro storage isn’t an issue.

        The only problems/questions left are:

        • Are the spaces spread out in the right areas, and can they be chosen in the right combination that won’t lead to problems down the line? (I think that’s beyond the scope of that document, but we’ll assume it is all good for now)
        • Time (let’s just assume it’s faster to get it all built than nuclear so we can examine hydro storage more)
        • Cost. Looking at the link I find:

        Thus, the expected cost of a 1,000 megawatt pumped hydro energy storage system with a head of 600 m and 14 hours of storage is about $1.8 billion.

        1000 MW = 1GW : $1.8B

        And your quote says we need 450 GWh of storage.

        So 450 x 1.8 = $810B

        (I’m assuming I haven’t made a mistake about the 14 hours of storage and the converting between GW and GWh).

        Our current GDP is 1.6 trillion.

        So we could do it, but it would cost us half of our GDP for one year (but we’d be spreading it out over multiple years).

        I’m assuming economies of scale would come into effect, but how much more efficient can you be at making and pouring concrete.

        I haven’t found any source on the fiscal cost of the Coalition’s plan (I doubt they even know, and I suspect that they’re just trying to extend the life of coal by relying on delays), but it begs the question:

        Would their seven proposed nuclear stations be cheaper than $810 Billion?
