Current profitability is up. Profit margins are also up from last year. But I could see investors looking at the lack of any path after the current Xbox and wondering why they employ so many there. I’m sure other areas have also seen some stagnation.

Damn. I used to frequent that site all the time from my teenage years up through college and even relatively recently. Their articles were always very in-depth and well written.

Yeah…none of that is true. Onshore wind is the cheapest power generation. Photovoltaic is second cheapest. Methane is leaky and raises your risk of asthma and cancer. You do not need to be tied to an electrical grid for anything with solar panels and batteries for energy storage.

They are using a strawman and trying to claim victory. They are not arguing in good faith.

I enjoy that you are making a strawman. Nobody ever said batteries have no negatives. You asked how they were leaner than natural gas. I answered. Sorry that the answer hurt your feelings.

Are you under the impression that we use NMC batteries for grid energy storage?? LOL
- Comment on US grid adds batteries at 10x the rate of natural gas in first half of 2024 2 months ago:
Mostly because natural gas is a one and done thing when it is used. Batteries can be recycled. Production of natural gas is largely done through racking which destroys the groundwater. While batteries often require mining (excluding mechanical ones), they often can be broken down and reused in new batteries. And of course there is the greenhouse gas emissions from methane that are horrible. Methane is extremely leaky. Methane usage emits about as much greenhouse gas emissions as coal does.

You know what pumped storage hydro is? A battery. Unfortunately that is not an option everywhere and takes up a massive amount of space. The space portion is not a huge issue for grid energy storage for the most part but it can definitely limit where you can do it and its capacity.
As for the amount of lithium available, there is absolutely more than enough considering it is one of the most abundant materials on our planet. Not that we need to use lithium for grid energy storage. Lithium is very high density energy storage which you are correct that is not a high priority for grid energy storage.
Basically there is no one solution for grid energy storage. There are mechanical batteries, medium density chemical batteries, and even “depleted” EV batteries. We just need to apply what is right for each particular scenario.
I’m not disagreeing with you overall. But I figured more info and context is helpful.

Solar/wind +battery storage is cheaper than natural gas and a hell of a lot cleaner. It makes no sense to go for a more expensive, dirtier form of energy.

What do you mean we can’t afford either? Are you telling me that somehow all other developed countries are able to afford free or cheap higher education but somehow the US cannot? We could also slowly start to cancel current student debt. Sure, it is at $1.77 trillion right now but that does not have to be wiped away all at once. Prioritize getting rid of predatory loans, then those those with financial hardship, then go from there.

I too prefer free tertiary education. But that also does not relieve the millions saddled with predatory loans.

It honestly took me a while to figure out why people were criticizing him. I read his remarks as a positive and didn’t realize he thinks having a work-life balance is a bad thing. Odd coming from someone who is fucking retired. “You work, I live. Things are balanced.”

- Comment on Samsung delivers 600-mile solid-state EV battery as it teases 9-minute charging and 20-year lifespan tech 3 months ago:
Thankfully solid state batteries save 30-50% weight compared to current ones so batteries can be a bit smaller than they otherwise would be. This one will likely be 150 kWh.
- Comment on Samsung delivers 600-mile solid-state EV battery as it teases 9-minute charging and 20-year lifespan tech 3 months ago:
Solid state has zero possibility of doing either of those. That is one of the big selling points. The others are that they are 30-50% get, they last longer, and they can charge faster.
- Comment on Samsung delivers 600-mile solid-state EV battery as it teases 9-minute charging and 20-year lifespan tech 3 months ago:
A couple things: solid state batteries weigh much less. Solid state batteries are 30-50% lighter per kWh. The initial ones will probably be closer to 30% lighter. A 100 kWh battery weighs about 1400 lbs (635 kg). Shaving off 400 lbs is pretty significant and results in much better range for the same battery capacity. The battery pack is likely closer to 150 kWh.
Second thing would be the charge rate. Yes, a supercharger can 250 kW output (not kWh BTW) but a few factors means that they often do not. First thing would be heat. If the charging cable or the battery gets too hot, the the rate slows down. The next thing would be the fact that current batteries have to start at a slow rate and end at a slow rate. Solid state batteries do not have those issue nearly as much and can more consistently hit that 250 kW output for a longer period of time.
This thing, they are likely using 350+ kW chargers. Higher than 350 kW is pretty rare but the odd 400 kW and 450 kW charger does exist.
And doing some more digging, I found that it is from 8% to 80% in 9 minutes. And even then, it does not say it is the same 150 kWh battery that is being charged that fast. This could be marketing crap where it is giving numbers for a ~85 kWh battery to compare it to EVs today. An Ioniq 5 takes about twice as long to go from 10-80% at 350 kW.

Unfortunately the source does not seem to indicate what Samsung is using.

It does say that LG will be producing a sulfide based electrolyte.

FTA:
Apparently, they are also rather expensive to produce, since it warns that they will first go into the “super premium” EV segment of luxury electric cars that can cover more than 600 miles on a charge.
So yes. Expensive initially.
