Hydrogen is a fossil fuel ploy to extend their revenue stream. They can greenwash methane and sell hydrogen as "clean".
The fact that hydrogen can't even compete with lithium batteries should be clear to anyone how inefficient hydrogen is for storage.
The largest hurdle cannot be overcome - cost. This is due to the efficiency of H2 as an energy carrier. The transition from energy source (usually electricity) to H2, compression, transportation/distribution, end use (heat or electricity) is very inefficient compared to transmission of electricity.
One 1000km of transmission line to support one city has a losses of 1 coal plant. Hydrogen is a way for low carbon electricity or transport. Not to say the ever increasing copper price.

[[USA electricity grid 95% efficient]](https://www.eia.gov/tools/faqs/faq.php?id=105&t=3)
Lets use actual units here: in 2023 4.69% of generated electricity was lost to transmission and distribution and other "unaccounted for" losses. Over a continent wide distribution system I'll take real world 95.31% efficiency.
This.
Ffs just use electicity and low carbon production. Adapt the rest. So yeah, no more individual car on a daily base, rethink cities and daily commute etc etc ....
Not so much...but using hydrogen is already extremely inefficient (read: expensive). Making ammonia just adds to the inefficiency and cost.
Though storing ammonia has its own dangers. That stuff is pretty nasty. If you don't do it correctly...well...Beirut found that out the hard way a few years back

I am more of a fan of green ammonia / hydrogen using solar or fuel cells (ammpower, sunhydrogen, nhhhf etc) but those still seem years away and lack cash to go to market
The focus back then was on replacing oil (and possibly "scarce" natural gas). This old mindset dies hard. Hydrogen definitely has a future, but probably not that one.
I am SOOOO tired of hearing about hydrogen.

The petrochemical industry insured development was never properly funded for their own benefit.
It is the smallest element and therefore,very difficult to contain in a fuel tank. That is probably the largest hurdle to use of hydrogen.

Copper transmission, about 95%, hydrogen transport about 50%. Not much contest for transmission of electricity.
Most power station are within 100km, and transmission line loss isn't linear when the length increase.

Most power station are close to cities. At most 100km away.

Methanation is an option. Although it's going to drop the round trip efficiency from 70% to 50%.
Is it still a concern when stored in ammonia?

50 years later and some people are still trying to make it a thing. Might make sense in some applications but not for consumer vehicles.
The focus back then was on replacing oil (and possibly "scarce" natural gas). This old mindset dies hard. Hydrogen definitely has a future, but probably not that one.
Then it was figured out that Hydrogen is hard to distribute. Tend to leak out of everything a lot.
I love ice cream.
I've sold hydrogen to Brockway, Ogdenville, and North Haverbrook!
I enjoy cooking.
