Why did we abandon hydrogen cars so quickly?

[x4it3n]

Hydrogen is too expensive and still dangerous. Cold fusion is the best technology we have as of now, it's a clean energy but the lobbyists are pushing for gas because the gas industry brings too much money. The reality is that our society is doomed because of selfish and greedy people...

And 95% of it comes from fossil fuel, and overall efficiency of using that fossil fuel is less than using it directly in a gasoline engine, so it is completely pointless.

Cold fusion

But... how cold? Yes I remember the fraud from pons and fleischmann. Do you remember that?

Isn't electricity powering BEV also made from fossil fuel power stations? What's the difference between making hydrogen with grid electricity and powering a car with it ?

Also worth noting there's nothing stopping hydrogen being produced using off peak green energy, especially for things like wind. Given there's no way to store it as of now. Plus natural hydrogen exploration is only just getting started.

BEVs sales are in big trouble and outright cratering in the Europe. Amazing to me people are pushing this technology when consumers just aren't interested much and for good reason. (Similar for a lot of other tech now as well like Consumer LLMs)

Check online there are plenty of topics talking about it!

Both Bill Gates and Jeff Bezos hugely believe in it, its technology is improving quickly and is a much better solution than lithium batteries for our environment.

Similar concerns, sure, but at least the efficiency difference is positive and the infrastructure isn't so absent.

Hydrogen is the same problem, except you use more fossil fuel instead of less fossil fuel and you don't have many options to 'recharge'. There is no existing hydrogen grid to utilize. Building the missing infrastructure requires more carbon demand. You don't build a hydrogen infrastructure in order to create a less efficient way to consume fossil fuel, unless your goals are money in opposition of the stated goals.

There is no natural hydrogen to gather and collect. It is too reactive.

The only way to efficiently use off-peak green hydrogen is to use it as off-peak storage tied to the grid directly. Make hydrogen fuel cells which consume electricity when the grid is in excess and consume hydrogen when the grid needs power. Do that with all the excess green power first. Then, when you have nothing better to do, waste your time with hydrogen cars. Make it stationary, efficient, and effective first. Similar reason as to why solar panels are on houses, not on cars. You do the thing that's most efficient and makes sense first. Then waste your time on investor-funded toys afterward. You don't do the less efficient thing first, especially when it is less harmful to do nothing at all.

This is nothing that it cold in process of fusion. The coils of the electromagnets and the walls of the reactor are cooled. This is no reason to call it "cold fusion".

My bad I checked and it's actually Nuclear Fission and Fusion that Bill Gates is investing on

The Microsoft co-founder has invested in at least five nuclear fusion companies.
