The calculation is wrong by a factor of 1000, and even if it were correct, that's like a week of typical container imports to the US ๐คก

The CATL TENER grid battery system contains 6.25 MWh capacity in a single storage container that is 20' long.
A 6.25 MWh battery can output 6.25 MW continuously for 1 hour, or 1 MW continuously for 6.25 hours.
We would need 148,800 TENER batteries to output 930 GW continuously for 1 hour. We would need 3,571,200 TENER batteries (22,320 GWh of storage) to output 930 GW continuously for 24 hours. However, the average continuous power demand in the US in 2025 was 466.21 GW. Now, that is an average, so the continuous power demand is sometimes higher than that but also sometimes lower than that. According to the EIA, the peak continuous power demand in the US in 2025 was 759.18 GW. We also have to understand that there would never be a time when all the electricity demand is coming only from battery storage. Between hydro, wind, solar, geothermal and all other renewable power sources, we would always be generating some electricity somewhere. Still, we would want a significant buffer, though we probably wouldn't need 22,320 GWh of capacity. But, yes, would likely need at least a million of CATL's TENER batteries to meet current power demand. That's a lot of batteries, for sure. Although, not an unfeasible number, imo.
That said, I think renewables with battery storage plus nuclear is the best course of action.
^sorry if any of my math is wrong^
OP is stupid and thinks there are a million megawatts in a gigawatt. It's a thousand. You only need 1550 barges to supply the entire USA.
Each barge is supplying an average of 10 cities, towns, and/or villages. So if each city is paying for its own grid storage, then Zohran needs to put together funding for 45 barges.
You only need 1550 barges to supply the entire USA.
*for one hour
OP not only fucked up conversion, but confused energy and power. Battery capacity is a measure of energy while grid usage is a measure of power.
I do think nuclear power is an important part of a healthy grid. But the problem is, nuclear power plants take a lot of very specialised knowledge. When you build a nuclear reactor with non-experts, it runs five times over budget and takes a decade. And right now, there aren't any experts at all. So we can't afford that much time, and we can't afford all that money. We need climate solutions that are capable of saving the world right now. Current generation renewables and batteries can save the world right now if our politicians are willing to pay the investment now and reap the cost savings later.
But, after a few reactor building projects, we will have a handful of experts who can build reactors on-time, on-budget, and while training a team of rookies. So I do think we should put a little bit of money into nuclear on an indefinite basis, once we're hitting our projected climate goals. I want to see what molten salt reactor technology can do in 30 years, after we've saved the world with renewables.
Shitpost!
About as ridiculous as "1.21 jigo-watts!"
Great Scot!
It's gigawatts but they mispronounced it because, well, in the movie it's 1955 and they much power was probably never heard of. IMO it was said wrong on purpose to show how absurd it was.
Batteries don't come in MW, GW, or even W. That's a measure of power. As in how fast it is being created or consumed.
Batteries don't create or consume power, they store it.
That is measured in Wh, MWh, or GWh.
You could measure their max. output in W.
But yeah, you are technically correct
Sir this is my shitpost not a Ted talk. I am referring to 1 MWh batteries.
Memes can be misinformation, too, so that isn't an excuse.
Oh, sorry.
Come to think of it, you can actually pull 930 gigawatts from any battery. Just not for very long.
Does that solve the problem?
You really can't though. The batteries both have a capacity (kWh/MWh) and discharge power (kW/MW) rating, but it's usually the capacity that is the limiting one. And for extra fun, the discharge power goes up as the battery has more charge, and the charging rate goes down.
It's just a rating. All cells are rated for some given amount of amps, but you can actually exceed that rating in bursts.
So I'm jokingly pointing out that you can theoretically pull as many watts as you want.
You can turn a MWh of energy into a GW of power, as long as you compress it into a short enough duration.
The battery (or any part of the circuit) just won't survive the event :D
This seems to imply that you just replace all fossil fuel energy sources with batteries which does not even make sense. Once the batteries have been discharged, how would you recharge them?
What should actually be done is scale up renewable power generation and then you'd use the batteries to balance out the difference between production and consumption, which takes a lot less batteries than trying to replace energy generation with energy storage (which, again, would not even work).
1 Wh = 3600 Joule
Fun fact you can actually store power in various ways such as pumping water uphill and having it run a turbine on its way down, or even as thermal energy in an underground molten salt pit. Li-ion batteries are not the only method unless nobody is connected to the grid and even then you could still use it but only at certain times of day.
The battery is 1MWh, not 1MW. There are 1000 MW in a GW. Therefore, two barges could contain enough charge to run a gigawatt datacenter for one hour, so you'll need a barge to arrive every thirty minutes approximately.
How about batteries (doesn't have to be chemical) AND renewable power generators?
Wow that's a lot of space! how much does a nuclear reactor take up?
How big is that compared to an abandoned mall building?
I'd like the area in football fields and the weight in elephants, please. You need to standardize these things.
The abandoned mall building is standard for volume duh
It's crazy to think that electricity isn't a necessity outside of the relatively modern human experience. Humans are architects of suffering.
Its way too early in the AM for me to do the math to make it a clean 1 GW
It would be 1667.
1667
