    So, what you’re talking about here is essentially the concept of “baseload power”, which is a very common talking point in anti-renewables conversation, including by well-meaning people who have simply come to accept it because of how often it gets mentioned in the media and in online conversations.

    But it turns out that we have known for over a decade that a mix of different renewable technologies do not need any base-load power stations to operate reliably.

      From your article:

      concentrated solar thermal with 15 hours of thermal storage 15-20%; and the small remainder supplied by existing hydro and gas turbines burning renewable gases or liquids. (Contrary to some claims, concentrated solar with thermal storage does not behave as base-load in winter; however, that doesn’t matter.)

      The real challenge is to supply peaks in demand on calm winter evenings following overcast days. That’s when the peak-load power stations, that is, hydro and gas turbines, make vital contributions by filling gaps in wind and solar generation.

      So basically the concentrated solar w/ thermal storage acts as a battery. I’m interested to know what the costs look like (is that the salt reactor thing I’ve heard about). And if you have lots of hydro available, then yeah, you can probably get away with it, and may even be able to pump water so the hydro station can act as a battery. However, hydro isn’t practical in many areas, and moving electricity long distances may be too lossy.

      I’m interested in the development of nuclear microreactors, which can be transported where they’re needed. I think they could potentially replace hydro in areas where it’s not available. So as areas transition to more renewables, these could operate as a backup in case simulations don’t match reality.

      I’d love to go 100% renewable, I just don’t think that’s feasible at the moment. But I could absolutely be wrong, I may need to read up on the latest energy storage options.

        Rubbish dump methane to electricity is cheap and effective. The Canberra mugga lane tip has had a pilot plant~~, not sure if it’s still running~~ generating 37 GWh a year

        Hydro on the mainland is pretty much just Snowy Hydro. There was a project from a former government to make that pumped hydro. I don’t think it has yet been finished. I don’t know whether the project has been cancelled

        37 GWh, now that’s a “random” number

        Solar thermal - yes, the leading technology is a field of heliostat mirrors focusing sunlight on a tower, melting and heating salt. That system can easily hold onto the heat in their salt for use at night

        CSIRO in 2014 thought it was possible. I trust they did the maths right.
