    I don’t think that’s true, do you have sources for that? Because my understanding is that solar/wind is cheaper than natural gas, but battery storage makes it way more expensive at scale.

      There’s a huge difference between day/night storage which is sufficient for most locations in the world that are somewhat closer to the equator, and seasonal storage. We have no good solution for seasonal storage at the moment.

        Exactly. Day/night storage can probably be met (at least partially) by using EVs (i.e. arrive at work empty, recharge from solar, arrive at home full). But that’s not going to be enough to get through the winter in higher latitudes.

        That’s why we need a reliable base load, and natural gas is very attractive because it’s:

        • easier to build than nuclear
        • way less polluting than coal
        • compatible with existing supply lines

        Battery storage is prohibitively expensive in many parts of the world, and there aren’t very many ready alternatives. I think we should be investing in nuclear power instead of utility grade battery backups, and we should be looking at EVs to help even out the day/night cycle.

        Hydro is a good option for this, if you have a big enough lake. It can ramp up and down very fast, meaning it’s great for filling in gaps between other renewables.

      Yah, downvote the guy for asking for sources for a baseless claim. I have heavy doubts that battery storage is anywhere near as cost effective as NG turbines. I’d love to see some real numbers on that.

      And I say this as someone with a house running on batteries and solar exclusively.

      What is your understanding based on?

      Regarding production batteries might be more expensive, but they can be charged some thousand times without any additional cost

        Just from looking at some government studies. This doesn’t necessarily compare longer-term costs, but it does give some direct comparisons between storage options.

        I’m certainly no expert here, but just throwing out some rough estimates of battery degradation, it doesn’t seem to be cost-effective vs natural gas, which is already only slightly more expensive than solar. So solar plus battery storage seems to be significantly more expensive than natural gas.

        It’s certainly more complex than that (i.e. you’d need less generation if battery backup is plentiful), but that’s the data I’m looking at.

          But how can one consider natural gas? The whole point is to avoid getting more greenhouse gases into the atmosphere?!

            No, the point is to put less greenhouse gases into the atmosphere. Natural gas is way cleaner than coal, and it’s quite a bit cheaper (from what I can tell) vs battery storage. Everything has a cost tradeoff, and the cost tradeoff for natural gas is very attractive right now. Maybe we’ll develop some really inexpensive energy storage (sodium batteries look promising), but regardless of what we come up with, there will be a transition period where we roll it out, and natural gas is a fantastic alternative until that’s done because supply lines are already in place.

              It might be cheaper but that is a pure capitalistic point of view. And capitalism is what brought us to our worlds current state

                Yes, the current state is a pretty near constant improvement on standard of living and a pretty steady decrease in greenhouse emissions (at least in the US) despite rising population and access to gadgets. Electric vehicles exist because capitalists found a niche and exploited it at a time when battery densities could finally support a reasonable range. Rooftop solar exists because people care and can afford to place them on their houses. Governments came in later to help encourage those, but the tech existed before the subsidies did.

                Capitalism isn’t the enemy, it’s merely a force that can be channeled to create a lot of good in the world. If a society sets up the right incentives, capitalism is incredibly efficient at meeting the demand.

                So we shouldn’t be destroying the economy to combat climate change, we should be channeling the economy to combat climate change. For example:

                • carbon taxes on everything - coal would get taxed out the nose, while solar would pay pretty much nothing, with natural gas falling somewhere in the middle
                • eliminate subsidies and loopholes - charge big trucks significantly more for damage to roads, which makes things like fracking a lot less attractive (if they have to pay to repair the roads they tear up, costs go way up)
                • remove protections for corporations - arrest execs instead of just issuing fines for irresponsible, greedy behavior that hurts people

                Most of the reason renewables are less attractive vs fossil fuels is because fossil fuels don’t need to pay for negative externalities like pollution. If we add that in, the market will adapt and change their operations to reduce costs.

      I guess it kinda depends on how and where you source your batteries.

      There was something in Australia I think that was using old EV batteries for grid scale power storage. As EV adoption goes up eventually old batteries will get pulled from vehicles, and reusing them for grid or even home scale power storage is a great use.

        Sure, but that’s a) going to take some time and b) not going to be very convenient. Pulling something designed for a car (e.g. built in to the frame) and putting it into something for the grid are very different design spaces, so it could end up being prohibitively expensive to retrofit these car batteries into the grid system. Each manufacturer is going to use a different form factor, potentially different voltages, different cooling systems, etc. It’s probably easier to break down the batteries and remanufacture them than to reuse them directly for grid storage.

        What I do think could be a huge boon is to use cars at rest as storage. A lot of people leave their cars plugged in all day at work (peak generation), as well as at night (no generation), which is a pretty decent fit for a base level of supply. You’d basically drive to work mostly empty and get home mostly full, and you’d get a discount on your energy bill for allowing your EV to be used for energy storage. I don’t know if any utility companies are using them that way, but that’s a fantastic way to get a bit more use out of EV batteries.
