Can hydrogen fuel cells replace EV batteries?

11 June 2022
Why are most of the electric cars powered by a battery? Is there a viable alternative?

Baron , 28 Jan 2024This is the only future. Oil will run out, rare earth minerals to make batteries will run out,... moreI can see a time where rare earths are not mined - Lithium is only a couple of steps up from hydrogen - but where they are made from other elements. yes it will take possibly a lot of energy but we may have that to..

This is the only future. Oil will run out, rare earth minerals to make batteries will run out, hydrogen will NEVER run out. As long as there is an ocean...

hypocrisy and the thirst and greed ...what are we waiting for we can make cars that we can drink from ....what are we waiting for..why why on eart isn't a country doing it wven if its a model same model same colour simple all the same but cheap and efficient even our health would improve...saad just sad thats why we the people should take back the power and decide ourselves the decisions yess with the internet we can take de isions and vote like they do....people we need to get together

Hydrogen engine/car burns oxygen from the atmosphere. Yes, you can suffocate in your garage even though the engine is not producing CO, NO, or other hazard gasses. Yet, a miniature hydrogen engine can charge the EV batteries at a slower but adequate rate. With a full charge and a full hydrogen tank the EV can go for 2k km without stopping to top off while living on occasional and usually short plug-ins.

A lot of bullshit here. Red hydrogen is ommited, tben electricity production efficiency is ommited, but hydrogen production efficiency is in. The grid losses for electricity amount to almost 30%, somehow here efficiency is 93%. Lots if crap.

BURNING hydrogen in a combustion engine similarly to gasoline is the cheapest way to manufacture carbondioxide-free vehicles.

1. Electrolyzers are even more expensive than batteries. And the inefficiency (which cannot be improved much with better tech as far as we know) means you'll need far more electricity to produce it. Li is quite abundant, just like oil, demand will increase supply. Furthermore, Na is now coming to market as well. 2. H2 cannot be used with equipment meant for NG, thus everything in house will need to be replaced. (Also pipes to house will need to be replaced.) 3. We **need** H2 for industrial uses like green steel, green fertelizer, etc and possibly for efuels for ships/aircraft. We definitely shouldn't waste H2 on what batteries do better, i.e. home and road transport.

kek, 13 Jun 2022I feel we should be better off improving the current fossil fuel process in order to reduce CO... moreEverything is good about your ideas, but sadly, emissions control and fuel mileage are inversely related to each other. The improvements through implementation of electronic Fuel injection, cat cons, etc have been realised and there's nothing more to do.
Now, we're making the world cleaner by making exhausts heavier and reducing fuel mileage.
Plus, even gasoline fire is dangerous, its fire goes upto 2100* C, its so hot that water evaporates before touching its fire base. People have died this way.

EV's, granted are bad too, they'll most likely explode on a big impact.

Hydrogen even if flammable spreads so well in environment, so its safer.
This way hydrogen makes a lot more sense, but all this tech stuff does make it expensive, but what other big demerit is there?

" A tailpipe you can drink from! "
But don't you think it will be terribly tasteless due to lack of minerals and can make you sick?

Anyhow, on this topic, let me just say that the first thing to be encouraged in electric vehicles is 80% charging rule. Unless you want to ride long distance, you must always charge 80% only.

This will ensure almost 3 times more battery lifespan, and less loss of charge holding over time.
Multiple research papers have been presented on this.

Replacing one expensive fuel for another even more expensive fuel you have to pay for is madness.

All that electricity being wasted to produce hydrogen can go straight into a BEV. Best of all, we can charge BEVs at home with solar panels, making that power, effectively free.

Thats my current situation. Why would I give that up?

How is that posbul

Yes some companies are producing( or starting to) cars or truck for hydrogen but thats because they think we will stick to li-ion chemistry for longer time and that just isnt true. Its just too late and too little effort by them as they (hey ,toyota) didnt bet high enough on hydrogen.

  • Lsi

My point was Hydrogen has no place in this segment!
Hydrogen technology and chraging infrastructure is just not developed enough at this time. Yes if we started developing charging station and cars trucks 5 10 years ago now we could say hydrogen could be a viable solution for transition to EVs but its just not here and it makes litteraly no sense to even look into it if you already have SS batteries knocking on your front door.

This is Dawn of Solid state batteries ....The story is similar to one from 1900s when ICE and electric cars(yes at that time) were trying to get their way to mass market.

At least one big battery company is already mass producing these batteries or is starting in 2023.
There is just too much Research and development involved thus money invested in solid state technology that its just matter of time when it will be available to us.

These batteries are extremely safe, they dont explode when punctured , and even if you cut it or damage it the battery will still continue to provide its electricy like nothing happened. Also they are smaller in volume when compared to same capacity of lithium ion and they can be molded or bended . Soon(2-3years) we will see them everywhere not just in cars.

Anonymous, 22 Aug 2022This article is so misleading. And what is the validation of the data? Ltt explained rightfull... moreimagine using Linus Tech Tips as your primary source of information LMAO
