This is a panic move because the Japanese car industry wasted a whole lot of time and money on hydrogen instead of EVs
I remember when Physics Girl took Shell money to promote hydrogen powered cars.
It was very suspicious that they never talked about how the hydrogen was produced.
And certainly never about the price of hydrogen. It's either running the car on fossil fuels with extra steps, or on solar and wind electricity with extra steps. Extra steps cost a lot.
I find her suspicious in general. She sends up some red flags for me, but maybe I'm just being a misogynistic hater without realizing it. Also, she and the Christian military dude (SmarterEveryDay?) have weird chemistry. I've asked YouTube to stop showing me anything from them so I'm not an expert. They both kinda creep me out, I don't know.
Dustin (SmarterEveryDay) has weird energy and not in a good way. It comes off as a little creepy.
I know he and Diana met at some YouTube function and have done collaborations. Even though I know their friends IRL, it was still a bit creepy to me that he went to visit her while she had long COVID right after she got married.
I will say that she didn't show any red flags for me until after she did the hydrogen cars series. I know creators have to get paid but still...it was like when Aubrey Plaza took Dairy Farmers money and did a commercial for milk.
Very off brand for both of them and lost a whole lot of respect when they did it.

Yeah, for sure. Having been around both evangelicals (especially) and Mormons a lot, I'm pretty sensitive to the "subtle" proselytizing and hate it. And it really comes off to me as if he has a thing for her and is being kinda weird about it, as repressed Christian guys are wont to do (speaking from past personal experience).
I didn't know anything about the hydrogen stuff until the earlier comment.
Fucking hell state of the world.
Someone can dislike a woman without being misogynistic. Calling every guy that dislikes any particular woman misogynistic is just sexist. Don't be scared of offending sexists.
And they still are. Toyota and Honda in particular have been spent billions on FUD and harebrained hydrogen projects and then wondering why China is eating their lunch. Meanwhile the doors are closing for non-EV manufacturers in markets which are going all electric coming up to 2030. Japan's auto industry will probably survive in some form but there could be a lot of casualties.
Hydrogen is still being developed by everyone, it's just more low key than what Japanese car makers are doing. It's still a much better means than battery is in the long form. Getting it from renewalable ways is what is taking a lot of the wind out of its sails.
Ok, I see misinformation like this on like every social media site now. I didn't know it had made it to Lemmy.
So, you know that conversion of energy causes energy loss, right? So how is it that converting that energy four times (original source > electricity > hydrogen > electricity > motion) sounds more efficient to you than converting that energy twice (original source > electricity > motion)?
Especially when you consider that electricity already has a network of well-established, proven, global distribution infrastructure whose transfer loss has been obsessively optimized over the last century, while hydrogen emphatically does not?
From the point of view of pure physics, it makes more sense to charge up a bunch of batteries and put them on a truck than to put a bunch of fuel cells onto that same truck. And remember, you can make those batteries more convenient by sending the electricity through the grid instead.
Charging times are quickly decreasing. They'll eventually reach a reasonable parity with gas tank fills, but they'll have become the dominant transportation energy source long before that. The current state of battery technology is the worst that it will ever be, and multiple industries are working together to make them better. Hydrogen pretty much only has wide applications to one industry.
Would all of this have been true if both technologies were starting from zero? Probably not. But electricity has a hundred year head start over hydrogen in the consumer space, and a lot of money is still being put into it. Plus, it's obviously going to be the eventual winner because physics, so why bother with the transitional source when what we would transition to is already a more mature technology?
The war is long over, and anyone who pretends otherwise is just ignoring the laws of physics.
Edit: I recognize that I'm papering over the transfer loss of electricity > battery > electricity. That's because the transfer loss of charging a battery is <10%, while the transfer loss of generating hydrogen is >20%.
While I agree that hydrogen is inherently inefficient, most batteries don't store electricity as such, you're still going electrical > chemical > electrical.
People saying EVs are the only future are closed-minded. Hydrogen hybrids are still extremely viable. You said “pHySiCs” as your source of truth without providing anything but snarky conjecture. EVs have limits and pHySiCs will eventually hold true there too. Also, not to point fingers wildly, but people who live in cities (especially western cities where weather means a lot less) are the champions of EVs and are far too dismissive of lifestyles they don’t understand and don’t pertain to them. EVs are great, but grandstanding on them in the way you are doing is bogus and short-sighted. I challenge you to venture outside your comfort zone and drive around in rural America for what actually makes sense.
Hydrogen, even with fuel cell/electric, is not suitable for rural car owners. It's only really suitable for vehicles that are constantly running, like freight trucks. Why? Because hydrogen leaks out of any vessel you try to put it in. It's the smallest element in the universe so it slips past the molecules of whatever sealing material you are using. It will even permeate through solid metal, making said metal brittle in the process. And this problem of course gets worse at higher pressures, which you have to use to get any energy density.
So not only do you have to contend with the terrible efficiency loss of using electricity to create hydrogen only to turn it back into electricity again, a whole bunch of your fuel is constantly leaking out during transport and storage. And then if you use cryogenic hydrogen for the best energy density it gets worse again because you can't keep it cold enough. It's constantly boiling off and has to be vented to prevent your tank from exploding.
So even if you solve all the myriad other implementation problems with hydrogen, you're never escaping the fact that you need to use all your fuel quickly or you're setting money on fire as it leaks. Not to mention potentially getting stuck because you didn't drive your car for a few days and now you don't have the fuel to reach a fill station.
Hence why, if it ever matures enough to become actually viable, it will almost certainly be limited to freight and courier type vehicles. They run near constantly and so burn through fuel fast enough that the leakage isn't an issue.
No it isn't, batteries are already better than hydrogen and the newest batteries coming out soon from BYD and CATL are going to please the people that want fast charging to be as fast as going to the pump. It's over for hydrogen in cars
Hydrogen in cars was dead from the get go, it has very niche use cases for the very few percentage of people who actually drive a shitton of kms per day, now it's only use case would be trucking, but I feel like that should transition mostly to trains with only final miles being loaded onto trucks and there Battery powered semis are not only viable but better imho.
The whole point is to get it renewable, otherwise gasoline is even better? Anyway, the race is still on for aviation and heavy freight, and hydrogen/ammonia/methanol would probably have a place there.
Getting it from renewalable ways is what is taking a lot of the wind out of its sails.
Could just use that wind to generate renewable energy directly....
They'll probably build hydrogen based hybrid cars lol
Batteries work great in a city, anywhere else they don't. This is why hydrogen ICE makes sense.
Hydrogen ICE is doubling down on hydrogen's greatest flaw: efficiency. It'll have some racing applications, but putting it in a common car is stupid as fuck.
Batteries seem to work fine in rural Norway. If you live somewhere warmer and/or with a bigger population or population density than Norway, you should be fine.
uh, no? Where did you get that batteries only work in a city? I have an EV which I take on long journeys regularly. I can drive for 4 hours (280 miles) on a single charge, then go for a wee in the services and have another 150 miles in the battery before I've flushed. I do a 12-hour drive once a year with two brief stops and I love those drives. So saying batteries don't make sense outside of cities is ludicrous.
Horseless carriages work great in a city, anywhere else they don't. This is why horse-drawn carriages make sense.
Except you're saying this in the 1930s.
Batteries work great in a city, anywhere else they don't. This is why hydrogen ICE makes sense.
I think most are going with hydrogen fuel cell rather than ICE. It’s more efficient, if also more boring.
Edit: why on earth is this being downvoted? Am I wrong? Are manufacturers working on hydrogen combustion now instead of fuel cell? Because a few years ago it was all about fuel cells in that space. So please, let me know if I’m wrong. For the record, I think BEV makes far more sense for the average driver. But HFCV makes sense for something that can build out dedicated refueling infrastructure and benefit more from rapid refueling, like trucking.
