Wikipedia: Steam reforming is the most economical and widely used (~90%) method to produce hydrogen. However, due to the use of fossil fuels, just as much of the greenhouse gas carbon dioxide CO2 is released as during their combustion.

This makes hydrogen nice and clean in the city. But somewhere the CO2 polluter called refinery has to be located. Very nice. Acceptance of a problem grows with distance ;)

Whether you get enough H2 by electrolysis if you cover the entire Sahara with solar panels?

But it's similar with electric power. Sooner or later/somewhere research has to start or be subsidized. Because research is rarely conducted at non-profit companies. Batteries, for example, are constantly getting better/cleaner, which benefits not only cars but also homeowners.

It's not just about the price, but also about the sometimes poor reputation or quality of domestic products. Since the Chinese milk scandal, for example, Chinese parents prefer German milk powder; many even have it sent to China by relatives here, which is why the sale in drugstores is often limited to 1-2 packages. Imported products from Europe have a better reputation, which is also why they are bought. Believing that simply making them sufficiently expensive will solve the problem doesn't really address the issue.

only unfortunately it is no longer so great for me either, just compare the number of patent applications internationally ...

That’s nonsense? You can just buy more expensively/better in the EU or start producing here yourself, then there will also be fewer electricity deaths in Germany and the lamp won’t cause a house fire. Besides, there are enough studies showing economically and ecologically positive effects with an appropriate Europe-wide CO2 pricing. Okay, I admit, this hasn’t been tried yet... Because 10 € per ton of CO2 is rather a joke (if even the German driver doesn’t loudly complain about more than 10 cents per liter of fuel, it must be so ;))

So. I like this because it is a logically sound position. It has realistically abandoned the belief that a world in which everyone does “their own thing” as they think could achieve the climate targets. So either you are in favor of supranational organizations that do nothing other than massively ensure through price interventions “from above” that fossil fuels stay in the ground. What is subsidized is also burned. Whether here or elsewhere, it does not matter.
Or you don’t want that and honestly say that climate goals will then simply be missed. So what?

Both options each have different consequences in the future that one has to face. One should then also speak about this fairly, about how one intends to deal with it.

Not so funny “fun fact”: Oil is today, adjusted for purchasing power, priced as it was before(!) the oil price crises of the 1970s. So what has actually been achieved internationally so far?

By the way, I am of the opinion that the long-term consequences of climate change will have more serious consequences than supranational coordination against the free market. But I can’t bet on that opinion, things will turn out differently.
