Why gsmarena posting car articles?
I thought GSMARENA is for phones only.
And by the way these scifi details went above my head.
Thanks for your hard work by the way.

No physicist but using power to generate hydrogen to then generate power for a small battery pack seems like a detour with a lot of power loss compared to just charging a battery pack.
Only positive I can think of are faster refuelling and maybe using less exotic materials for battery production ?

Two major things NOT said in this article.
1 kg of hydrogen is more dense than batteries, but once you add the massive hydrogen cylinders, they are NOT.
Fuel cells NEED large batteries. They cannot deal with peak power of acceleration, and be interested to see top speeds. They are basically expensive range extenders.

The problem with hydrogen is that it has the smallest atoms out of all elements. It is diffcult to store since it penetrates other materials like iron.

The European union bans ICE cars from 2035 and on but with the exceptions (which was proposed by Germany) that biofuels are allowed.

There are no other known synthesis pathways for Lithium, which includes stellar/supernova nucleosynthesis, and neutron star mergers.

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.

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.
