It's a fair point (why curtailment is in effect), and I think speaks to the fact that more granular and timely data is needed wrt all nodes and transmission segment within the system. Also a call for more batteries everywhere between generation and load.

With regards to transmission congestion, that is easily fixed with installing batteries at currently storageless renewable generation facilities (the batteries then charge with excess solar, and can continue to discharge after the sun sets or the wind dies down, maximizing transmission utilization temporally). The Inflation Reduction Act also enables those batteries to charge from utility side if needed, whereas before they could only charge from the renewable generation (AC vs DC coupling).

Batteries are extremely expensive per megawatt, not very durable, require carefully controlled temperatures, and their manufacturer and recycling extract a tremendous cost from the environment. For non-mobile usage, batteries shouldn't be seen as any kind of viable solution at scale.

However, there are other ways to store energy; unfortunately, most involve converting electricity to another form of energy such as potential (gravitational) energy, like pumping water uphill or lifting heavy weights. These also have relatively little long-term environmental cost. Unfortunately, they're a bit more inefficient (but so are batteries, relative to some other forms of stored energy such as fossil fuels).

It'd be interesting if we could find some ways to convert landfills or other urban blight issues into a durable energy store without poisoning the environment.

Lithium-ion, sure, but aren't there a whole host of other battery chemistries that are basically too big / too heavy to put on vehicles but a lot cheaper so well suited for stationary storage?

Are they all still at the research phase and so currently more expensive than the decades-of-learning-curve lithium-ion?

[energy123]

Lithium-ion is the cheapest form of stationary storage for the sub-8 hour duration niche. The vast majority of battery storage being deployed is lithium-ion.

Sodium-ion is the second largest contender, with a few pilot facilities opening in China recently, but it will be a few years before it eclipses lithium-ion.

The vanadium redox flow battery. https://en.wikipedia.org/wiki/Vanadium_redox_battery

> For several reasons, including their relative bulkiness, vanadium batteries are typically used for grid energy storage, i.e., attached to power plants/electrical grids.

    VRFBs' main advantages over other types of battery:

    no limit on energy capacity
    can remain discharged indefinitely without damage
    ...
    wide operating temperature range including passive cooling
    long charge/discharge cycle lives: 15,000-20,000 cycles and 10–20 years.
    low levelized cost: (a few tens of cents), approaching the 2016 $0.05 target stated by the United States Department of Energy and the European Commission Strategic Energy Technology Plan €0.05 target

(and yes, there are disadvantages too)

How is 10 - 20 years "sustainable"?

[toomuchtodo]

We’re currently experiencing a Cambrian explosion in battery tech. As the technology matures, and we establish a closed loop ecosystem to build and then recycle these systems, longevity can improve over time. To get better at something, you must first suck at it, and 10-20 years is not an immaterial service life for an asset that just sits and hums with no moving parts.

[gunapologist99]

I agree if we were talking about a motor or a pump, but it seems like batteries basically devastate the environment every time we make one, and doing that millions of times every ten years is probably not great. (But I don't know anything about that specific battery technology.. perhaps it's just saltwater and two dissimilar metals.)

[megaman821]

Not a single thing you said about batteries is true. Pumped hydro is in no way competitive with batteries for most locations. In the future it is likely they won't be competitive in any location.

[jillesvangurp]

Better still; the amount of deployed batteries world wide is projected to overtake the amount of deployed hydro this year. Pumped hydro is barely growing. Battery capacity is growing exponentially to eclipse it this year. That's driven by pure economics. Cheaper, better, faster, etc.

[gunapologist99]

Neither of these points are conflicting with my argument. Just because batteries are being deployed it (and I agree that it's cheaper and faster, but not necessarily better on all axes) doesn't mean that their manufacturer is not damaging the environment.

In fact, battery manufacture is not damaging the environment in most places where first-world people live, so perhaps they just don't care, but I think that's pretty sad.

[jillesvangurp]

If that wasn't clear, I wasn't trying to challenge your argument; just adding to it. And you are right by adding more arguments to the pile. Not disagreeing at all.

A recent article asks:

"Why did the U.S. miss the battery revolution?"

https://www.noahpinion.blog/p/why-did-the-us-miss-the-batter...

About half the comments on the article were Americans saying very similar things to your comment and denying there was a revolution to have missed, which kind of answers the question posed.

[energy123]

They're the cheapest form of storage after recent price declines, even cheaper than pumped hydro and compressed air.

The secure authentication of all those nodes concerns me. Are these old scada systems coommunicating over plaintext rs232 or similar? Is it something running crowdstrike?
