Whatever comes next I‘m prepared to be deeply disappointed by my government and our European partners on this. „Make gas cheaper“ is probably at the very top of every leader‘s to do list tomorrow.
I always love the stupidity of this idea: You were able to generate pure hydrogen at high costs… Now what should we do with it? Well lets just do what we did since the middle ages and burn it!
If you’re launching a rocket, sure. If cost or difficulty matters in any way compared to raw mass, not really.
It was talked about for cars where density kinda matters, but you could put them in a fuel cell that way instead of just burning it, and I’m not sure if it was ever anywhere close to economical.
The cost probably will go down, and with any luck the cost of polluting will go up, but electricity is going to be more practical for most things.
Electricity has gotten dramatically more expensive too. It is no panacea. In all likelihood, most of transportation will shift over to either green fuels (e-fuels) or hydrogen. Those are one-to-one replacements for fossil fuels.
I mean, to make e-fuel you still need the e (which stands for electricity). It’s ~guaranteed to have lower round-trip efficiency and higher cost in a car than just a battery. Ditto for green hydrogen. Theoretically blue hydrogen or white hydrogen could be used instead, but it’s not certain how much white hydrogen there is, and blue hydrogen needs carbon capture and storage which will add a lot to the cost.
Gas generators are pretty much the same as ever, while renewables have gotten much cheaper than them. If your power bill went up, it’s some local issue doing it.
(Air-breathing aviation is the other application I didn’t mention. Battery planes work but not well, so it’s closer to rockets. I don’t know if anyone has tried hydrogen, but that’s where e-fuel comes up a lot)
Round-trip efficiency is not that important. If it really was as important as claimed, we wouldn’t be talking about cars at all. It would all be about bikes, buses, trains, walkable neighborhoods, etc., instead. But in the real world, we will need to accept less-than-perfect solutions. So as long as the idea is green, it should be tolerated.
We also have far more renewable energy available to us than we could ever hope to use. It is orders of magnitude more plentiful than fossil fuel energy. As a result, there will be an overabundance of green energy in the long run. It is fine to use that excess of energy to make stuff e-fuels or hydrogen.
You forgot about the part where the possibility of generating hydrogen cleanly from electricity later is used as an excuse to build infrastructure and fuel-cell cars for it now, even though hydrogen now is dirty hydrogen produced by cracking fossil fuels.
I have no confidence that the second phase of switching to electrolysis would actually happen, and that “the hydrogen economy” isn’t just a greenwashing scam perpetrated by natural gas producers.
Sodium ion batteries are already in production. They’re not quite at the energy density of lithium but it’s close and also irrelevant for grid storage.
I mean sure but if you already own an electric car then a spike in battery price doesn’t particularly affect your day to day like a spike in gas prices would.
Yeah fair, it’s mostly useless in my state, but very prevalent in other states I just forget it exists. But also swapping a stove, water heater, and AC is still a lot cheaper than a new car. (I mean the AC is the only one that’s even close) are there other things people use gas for I’m forgetting?
Heating. Swapping which is far above the price of a used car.
Edit: i realize now you said water heater, but switching off gas generally involves swapping the entire heatinf system, the costs of which are usually 5 digit for a single family home.
Yes, it is more so the efficient processing and refining that is rare.
You can make a T-shirt anywhere, but if you have to first build your own cotton farms and factories locally, construction will take years and your shirts will cost 10x more.
It seems to me that every major conflict (Russia, Middle East) spikes oil prices, relatively unpredictably (if you can call this unpredictable).
Maybe the world should look for alternative sources of energy, which are abundant, cheap, and can be deployed non centrally?
No. No that’s insane.
The pedofile parasite class says no

These prices are literally controlled by price-fixing cartels.
But Europe is investing hundreds of billions in North Sea wind farms to generate hydrogen for heating, it was initiated by Putin’s actions.

Now we just have to hope that people dont dig up this bullshit idea of using hydrogen to heat your own house.
Like, in place of natural gas?
I always love the stupidity of this idea: You were able to generate pure hydrogen at high costs… Now what should we do with it? Well lets just do what we did since the middle ages and burn it!
Hydrogen has one of the highest energy densities by mass. It’s a very reasonable energy storage
If you’re launching a rocket, sure. If cost or difficulty matters in any way compared to raw mass, not really.

Well, there are useful appliances for hydrogen, where you just burn it. Burning it to heat your own home isnt one if them.
There’s really nothing wrong with generating hydrogen when power costs are negative.
Except that only happens like 500 hours a year.
And hydrogen will leak from any tank.
And it turns metal brittle.
And I wouldn’t trust my neighbor with a propane tank, let alone hydrogen.
And its nearly impossible to transport through existing infrastructure.
But other than that, its great!

What’s that? I couldn’t hear you over the nonstop greenwashing of gas cracking plants.
Wow! so glad we have clean coal now!

The Gang Heat Their House With Hydrogen
Gas is not oil.
Why is this downvoted? This guy is technically correct.
Because Lemmy. Facts lose to feels.
Yeah, but power sources that don’t spew fumes are for limp-wristed queers. /s
Yes, then we will fight over Rare Earths.
Sodium ion batteries are already in production. They’re not quite at the energy density of lithium but it’s close and also irrelevant for grid storage.
Rare earths aren’t just used in batteries, lol
Are they? I haven’t really been able to find any being offered.
https://electrek.co/2026/02/05/first-sodium-ion-battery-ev-debuts-game-changer/
Cool! I kinda meant “can I buy the cells”, but if they’re being produced in car scales, it’ll probably be a yes pretty soon.
After a little more digging, yes you can!

I mean sure but if you already own an electric car then a spike in battery price doesn’t particularly affect your day to day like a spike in gas prices would.
Much of Europe uses gas for heating their houses. Much of industry uses vast amounts of gas for heating all sorts of materials from asphalt to bread.
Yeah fair, it’s mostly useless in my state, but very prevalent in other states I just forget it exists. But also swapping a stove, water heater, and AC is still a lot cheaper than a new car. (I mean the AC is the only one that’s even close) are there other things people use gas for I’m forgetting?

I think bombs dropping on heads will still affect daily life.
Rare earths are not geographically rare. There is just a lower % of them per sample.
Yes, it is more so the efficient processing and refining that is rare.
You can make a T-shirt anywhere, but if you have to first build your own cotton farms and factories locally, construction will take years and your shirts will cost 10x more.
They also are used in ICE catalytic convertors in every vehicle. But, unlike ICE, EV rare earths can be recycled.
You can recycle catalytic converters though, that’s really not the big problem for combustion engines…
