Which means the oceans will rise and engulf the earth. We'll have so much water, we'll be trading cars/trucks for boats. The Mrna vaccines predicted this which is why our DNA will now allow us to evolve into having gills behind our ears and webbed feet. No, no thnak you hydrogen.
This has been around for quite a while.

This is an episode of NOVA from 1979. At about 10:40 the concept of using a polymer is demonstrated.
If only we could find hydrogen in a more concentrated form, like a thick viscous liquid that we could refine it out of.
If you use atmospheric air as the oxygen source, there would be some NOx formation as a side product.
Don't worry - You'll be fine if you wear an asbestos raincoat.

Second Law of Thermodynamics: You can't even break even.
True in all energy conversions but the energy may be in a more useful form.

Probably destroy the Earth or something.
Again, I hope you’re joking too. Taking it from, then putting it back into water, won’t be much of a net change. If any at all.
Not economical yet. The vast majority of hydrogen is produced from natural gas
Hydrogen as a storage medium for use in automobiles and much more.
Yes, hydrogen can and will do that. Solar hydrocarbons will do that too eventually and those can also be sequestered or turned into carbon solids. It will all be part of the mix.
Burning hydrogen results in water. Water vapor is a potent greenhouse gas. What now?
Yes, but it has one major benefit. If we use the surplus solar or wind to create it (or create directly with solar), then it provides energy storage. Right now renewables are becoming economically worthless without storage. There are times when wind power is dumped. Colorado utilities now require wind turbines to be under their control so they can turn them off.
So then you’re ‘covered’, eh?
Too much carbon and energy waste. Natural gas has a lot more H to C (CH4). So that's what they use to produce most hydrogen.
Water vapor is a short term cycle so nature will get rid of it. But if you are concerned about that, we can make hydrogen by pulling water vapor from the air.
Use nuclear power plants to create electricity for refining water into hydrogen fuel via electrolysis.
He says the tech could challenge batteries in both efficiency and environmental friendliness.

Oh? Where does the hydrogen come from? Currently it comes from hydrocarbon fossil fuel. In other words, you discard the carbon and store the hydrogen.
Hello? Discard carbon? “Environmental friendliness”?
The practical offshoot of this issue is that you have to waste lots of carbon. Burning carbon provides the majority of the energy provided by burning hydrocarbons. Why would you discard overt half of the energy contained in hydrocarbons?
Because you’re an idiot.
I don't know if I'd describe those methods as "great", but using wind and solar for electrolysis and technologies like the one described in the article for energy storage form a sort of ecosystem of offsetting deficiencies.
Solar and wind have a problem: the energy they collect and harness isn't available on demand. The energy is "free" (more accurately the energy is already present in the environment from the sun), but it needs to be stored to be most useful because the sun doesn't always shine and the wind doesn't always blow.
Electrolysis has a problem: physics. It takes more energy to split a water molecule than you can get out of using the resulting hydrogen and oxygen.
Storing the energy from an inefficient conversion is great, but it probably doesn't scale to an industrial level without a huge infrastructure investment and equipment footprint, much less scale to mass consumer use. That is not a particularly sexy problem to solve, but even in a niche industry use, it could certainly have a lot of value.
LOL, yes.
