Clean Green Hydrogen Production

What kinds of materials can they use to make the tanks to store and transport the hydrogen, without embrittlement?

Carbon fiber is the only one I know of, but of course it depends on what form the hydrogen is in...in some cases high pressure storage is not necessary...

Hydrogen storage...

As usual, the nuclear advocates "slide over" the storage of the spent rods. The nuclear advocates are trading carbon pollution for radioactive pollution.

Spent rods are housed and stored, definitely not polluting, and not contributing to air pollution or global warming....

Until a natural or unnatural disaster occurs. Then, the radioactivity can kill every living thing. Unlike carbon pollution which is slow and can be halted, radioactivity kills quickly and completely. To believe humans can safely keep spent rods for fifty thousand years is stupid. Or, to be more political correct, is irresponsible.

You seem to think spent fuel rods are a lot more dangerous then they actually are...The storage caskets are a lot more robust then you must think...

..."Plutonium has been stated to be 'the most toxic substance on earth' and so hazardous that 'a speck can kill'.

Comparisons between toxic substances are not straightforward. The effect of plutonium inhalation would be to increase the probability of a cancer developing in several years time, whilst most other strong toxins lead to more immediate death. Best comparisons indicate that, gram for gram, toxins such as ricin, some snake venoms, cyanide, and even caffeine are significantly more toxic than plutonium.

Nevertheless, plutonium is toxic and therefore must be handled in a responsible manner. Its hazard is principally associated with the ionising radiation it emits. However, it is primarily hazardous if inhaled in small particles."...

..."Most nuclear waste produced is hazardous, due to its radioactivity, for only a few tens of years and is routinely disposed of in near-surface disposal facilities (see above). Only a small volume of nuclear waste (~3% of the total volume) is long-lived and highly radioactive and requires isolation from the environment for many thousands of years."...

The fact is we can reprocess nuclear fuel like the French and other countries do, but we don't...We can also build reactors that can use spent fuel rods as fuel, but we don't....the reason we don't do these things is because of the irrational fear that has been instilled in the public mindset by misguided do-gooders...probably the main reason we are using so much fossil fuels to begin with...we are guided by irrational fear by people that have money and influence but no real knowledge in this area....it's the equivalent of getting vacation advise from a child that has just watched a slasher movie at a vacation resort instead of a travel agent that has just been there...

I think nuclear solutions should be a different colour - blue, for the halo they have. Some think a halo is a good thing (those with a religious belief) but others recognise caution is required.

There is a concern we are leaving a greenhouse problem for our descendants, if we leave them with a world peppered with radioactive stores, they won't thank us at all.

Radium's half life of about 1500 years is not insignificant. How many generations does this represent? I watched this recently...

Yeah and watch out for those radioactive banana's too....!

Haha...

"radioactivity kills quickly and completely" How many people have you known who died quickly and completely from radiation?

The Japanese government has recognized about 650,000 people as hibakusha. As of March 31, 2020, 136,682 were still alive, mostly in Japan. The government of Japan recognizes about 1% of these as having illnesses caused by radiation.

There have been 154 fatalities from wind turbines to date, with over 200 reported injuries per year increasing every year, add to that the birds and bats being killed by the 100's of thousands and you can see that just wind turbines alone are more dangerous than nuclear power plants....

Even solar power causes more deaths than nuclear...

Nuclear power generation has the cleanest safest record....by far

Nuclear generation is even safer than hydro electric....

I wouldn't worry about ANY waste of ANY kind. We can now generate frequencies up into the THz range. When we develop switches that can switch at those rates, and control them, like we can control lower frequencies now, we will be able to dissociate molecules electronically. We will "DSP" them. And when we realize that "anti-matter" is just regular matter that has been inverted, we can make all the clean fuel ever needed.

Better living thru electronic chemistry.

Yeah, I'm still waiting for the kitchen of the future you promised 70 years ago while cooking a burger on my "George Foreman Grill"...
