More grid storage means more capacity for renewables.

You say that as if solving grid storage wasn't one of the most important problems humanity faces right now.

You will almost certainly see sodium-ion in cars. The Na batts already manufactured have a similar Wh/kg to Li batteries in EVs today. That's because Li has progressed further, and it takes a few years for new batteries to go into actual EVs. Manufactures don't necessarily use the top of the line batts, either, for cost or availability reasons.

If you feel a VW id.4 or a Hyundai Ioniq has sufficient range right now (or could have sufficient range if charging infrastructure was a better), then an Na batt will also be good enough. It'll also be cheaper. Those cars come off the assembly line with Li batts that are similar to the 160 Wh/kg that Na batts out of CATL were doing in 2021.

I can't remember the name but I'm pretty sure some Chinese EV manufacturer has started to make EVs with salt batteries already.

Sodium ion batteries on the market right now are about the same weight density as lithium poly batteries from a few years ago. It takes a few years for a newly manufactured battery to find its way into actual EV models. That means the newer sodium batteries have about the same performance as batteries in EVs right now. They're also cheaper and are made of more abundant materials.

Don't write off sodium batts in cars too quickly.

Why not? From what I've seen, they're about 75% as energy dense as lithium, and a lot cheaper. So if the Chevy Bolt gets 200-250 miles range on lithium batteries, I'd expect 150+ miles w/ sodium-ion, which is plenty for my commute. If the battery costs half as much and lasts 5-10 years, I'd buy that to replace my commuter in a heartbeat. Give me a commuter at $15-20k w/ 150 miles range and I'll buy.

Everything bad you expect is going to happen.

There is already a Chinese EV that uses a sodium ion battery, the JMEV EV3.

It's a tradeoff of range vs price. The EV3 only has 155 miles of range, but thanks in part to its sodium ion battery it costs only $9220 new. Which is a price that will probably drop even more as more sodium ion plants come online and economies of scale kick in.

EDIT: even if your commute is 40 minutes long, driving 60 MPH the entire way, that range is enough to get you to work and back using a little more than half your charge. Given that it's also generally cheaper to charge an EV than pump gas, and there's less maintenance costs, I think there's absolutely a market for such a car.

The volumetric energy density is 60% of lithium ion batteries, but the energy density per kg is more like 75% since the batteries are lighter. Assuming that scales to the ev range, that’s probably sufficient for a lot of use cases.

I don’t know why they said this — they really aren’t a viable alternative for weight-sensitive contexts at all. Their density is only abut 60% that of Li-ion batteries, and that isn’t even getting into solid-state Li batteries which are even more dense. If weight isn’t an issue, like for home or grid backup storage, they’re fine. For cars or bikes, not so much.

Your explanation is valid for vehicles that have 100% of their battery be something other than Sodium based, and also have a use case that requires long or intermediate range. That isn't all use cases. Vehicles that drive a lot, but never cover much distance would still be valid use cases for 100% sodium. 100% Sodium Ion powered EVs started rolling off assembly lines in Dec of 2023. Alternatively 100% Sodium Ion could also be for things like fork lifts or Semi trucks that move storage containers from a cargo ship to a storage location within a mile and repeat this trip dozens of times a day.

Other use cases would be where a car has some sodium batteries and some lithium based ones. The sodium batteries could serve most of the "wear and tear" of short trips, with a second smaller lithium back available to augment overall range which is not used as often.

Unless we get to the point where we do battery swaps in cars instead of charging. Just pull the fusion core and pop in a charged one. If we can do it for propane tanks we can do it for cars. Run out of "gas"? Tow company can bring you either a full charge or a smaller battery to get you to the next swap point. Most likely this will start with cross country trucks, the owners can have swap points or drive out a battery for a truck that ran out early.

A small town near out together an incentive package for a wind farm that was shopping itself around the country.

They imminent-domained hundreds of tiny plots of land from local farmers so a billion-dollar wind installation could go up without paying the farmers, and in return the city received $200,000 it used to paint a school, and the peoject it created a whopping 2 full-time jobs after construction was completed.

And the mayor acted like it was a victory.

if you think factories are bad wait until you find out what amazon gets away with. They can literally break fire code because nobody cares enough to do anything about having the worlds biggest retailer warehousing in your county/state.

Of course. The pork industry in NC is exactly the same. Tobacco as well.

NC has a strong Republican majority in the government with a fairly weak Democrat governor. They make bad decisions. I'm not sad I left.

Yeah, probably wrong. There's not a bunch of third party info on the environmental impact this factory will have, and no evidence anyone was bribed. If it makes you feel better, this isn't their first factory and I couldn't find any negative news about that factory either. Community leaders were supportive though, and a bunch of jobs were created.

I did find some articles about the positive environmental impact sodium batteries have from production, to relative ease of recycling, if that makes you feel better.

An issue near me: a major plant is fined every time they exceed emission limits and those fines go back to the community.

Yeah, it's probably GWh, W and Wh are frequently interchanged.

yes

Put up a shack, hire 10 people, pocket the remaining money, pay it to yourself in dividends and stock buybacks. Huzzah!
