They exist and relying on them increases fragility of the energy system as they can be used for storing energy that’s produced at one point of the day and returning that point at another point of the day while at the same time they are too expensive to store energy in reserve for periods of multiple days/weeks/months.
Batteries essentially do the opposite of Netflix chaos monkey when it comes to system resilience.
Not at the scale that would be required to power the entire grid that way. At least, not yet. This is of course just one study (h/t Vox via Robert Wiblin) but provides at least a rough picture of the scale of the problem.
This is disingenuous, I think. Of course they don’t exist at the necessary scale yet, because the market is small. If the market grew, and was profitable, scaling would be possible. Rare earths aren’t rare enough to be a real constraint, we’d just need to mine more of them. The only thing needed would be to make more of things we know how to make. (And no, that wouldn’t happen, because the new tech being developed would get developed far faster, and used instead.)
Sorry, I didn’t mean to imply that there isn’t a current practical problem with solar / wind; my reason for my previous post is that I read Christian’s statement as implying that it is fundamentally physically impossible to rely on solar without being chronically exposed to outages, which simply isn’t true, but it is true that we still need to develop our technology and infrastructure to accommodate the dynamics that exist with solar power
To be clear, I am in favour of using nuclear power for precisely this reason, although it also seems that the problems with renewables will be taken care of by the free market fairly quickly as renewables make up a larger proportion of our energy consumption
We really don’t need to rely completely on solar and wind to avoid the climate change. The estimates of Ipcc includes solutions that also have nuclear phase out, it marginally increases the cost, a two years delay in the energy conversion costs us more.
I’m sorry for repeating this, but I feel that my point before was missed; the issues from 100% renewable energy sources are a fake problem.
They really have no consequences on these decisions, since it’s not what we are required to do in the short term.
My initial comment did speak about current technology.
they will more or less be quickly solved by the free market as renewable energy becomes a larger proportion of energy consumption
Free markets don’t to be good at producing the kind of batteries you need to have reserve capacity for your once-in-ten years weather event that has two weeks of less sun/wind then you would usually expect.
Batteries are a thing that exist
