as far as I know, ITER has the goal to crack the next order of Magnitude, a Q>10

First Plasma expected in EO 2025... we'll see.

They are doing both, actually.

China has one third of the worldwide solar generation installed, and is increasing the lead.

You introduced iron phosphate. I was always talking about Iron air.

You introduced burning fossil fuels. I was always talking about using excess renewables.

Oh... And I had 2 years physics as part of my bachelor& masters in aerospace engineering.

I am out of this discussion.

Dude...sorry to be so blunt, but you have no clue what you are talking about. If the podcast is as good as you claim (which is possible because I kind of see the points it's trying to make) you didn't really understand it.

Please, as a absolutely bare minimum go on Wikipedia and read up on ammonia synthesis.

While you are there, you can also look up the composition of iron-air battery.

Okay, you're mixing up quite a few things here.

a) None of that explaines why hydrogen is trash

b) even if Lithium will stay the "best" type of battery, for grid storage where space is less of an issue other battery types will come online that are way cheaper and have less enviromental impact. We already have some. (Iron air, Redux flow,...)

c) You are also mixing up energy generation and energy storage. You can't put a nuclear reactor in a motorbike. Also, we won't have enough nuclear fuel, and it's not exactly clean to mine either if we use nuclear for everything.

d) what do you thing Ammonia is? NH3. You want Ammoniak, you need hydrogen first.

e) one important goal has to be to use less energy, so hopefully we'll need less renewables that one would think. We already had summers with negative energy prices in Europe, with more and more Solar panels & wind turbines being installed, thats going to happen more and more.

please please watch less youtube videos.

Green hydrogen only makes sense if you scale your generation for winter needs, and therefore have excess in summer that you can't use otherwise.

And it only makes sense for stuff that you can't power otherwise. (ie efuel kerosene for aviation)

So sorry for being ignorant, I only had two years of physics at university.... but what exactly goes against physics?

In my home country, we're expanding renewable energy generation to a point where we have excess energy in Summer to ensure we have enough in Winter. With that, we'll need an energy dump to keep the nets stable, and preferably one that allows us to store energy for other purposes down the road.

While the efficiency of Hydrogen generation from electricity isn't great, it's better than nothing and can be used as a precurser for artificial fuels.

I agree with you that whatever can be powered by electricity directly should be powered directly, but for stuff that cant, hydrogen and derivates are the next best thing we have.

You are right, but it still is a fuel. Not everything can be run with batteries and extension cords, at least not right now.

Cost. If you've got long rail lines that see one train a day or even month, the cost to electrify that line is huge. Way easier and cheaper to send a hydrogen engine.

I doubt it. In Germany started in 2000 with large scale investments in renewables, so there are plenty first-gen solar panels out there. And I haven't heard of major issues. Efficiency goes down over time, yes, but other than that, it seems as unless you drop a mobile crane on the roof, they hold up fairly well.

Solar on my roof was 1,40€/ watt... And I didn't need any transmission lines on top of that.

Not sure where you are located, but typically use during the day, when businesses are operating, people are cooking, washing,... Is higher than during the night.

In addition, in sunny areas the correlation between "it's so hot we need an ac" and "sun's out we get solar power" is not that bad.

maybe not all, but an awfull lot. Because thankfully, we tend to use most energy during the day.

Well, I guess about 7 years until most new cars are electric. 13 until all new cars are electric. I'd say 20 till most cars in Europe are electric. And in 30 years, the only ICE cars are young/oldtimers.

In the same time frame, most gas stations will disappear.

While that's still some time, it's still going to happen within my lifetime...

You mean, you'll build your own car from scratch and produce your fuel yourself? Because there won't be new gas powered cars at some point, no used ones at a later time, and with demand going down, gas stations will disappear as well...

They claim as much power as 16 solar panels, I'd assume that's about 4.5kwp.

Even if it would be half of that, I'd be interested, not as a replacement for my solar roof, but as an addon. Might be enough to cover the remaining demand that solar can't cover for us.

That's why Germany is phasing out both nuclear and coal, yes.

You only have the added cost if you actually store it.

If you usually run on coal all day, but now cover daytime with solar, you only burn half as much coal as you did before. If the weather is shitty, you are back to coal, but that's still better than burning it all the time.

Yeah, storage is a big issue for the future, but right now, in most areas, we're not at a point yet where we really need it.

Efficiency doesn't matter that much, if the energy source is the sun.

In the end, it's the kwh/€ that matter.

No it's not. For grid level stora, there are plenty of options without lithium. Redox flow, or iron/air comes to mind.

Also, if we cover daytime use with solar, we've already covered quite a big chunk of our energy useage.

Solar panels made out of lithium?

Yeah, sure.

No.

It's tech, we rarely have revolutions, we usually have evolution.

All those breakthroughs will help battery tech getting better, one step at a time.
