Earlier quoted context omitted.
Hydrogen leak because it's damn small, so you tank can hold it as a not-watertight tank can hold water, for a certain amount of time but not forever. We have tempted various routes, micro-foams included, none succeed completely. Surely as long as there is no accumulation risk H₂ leaks are harmless, but you still loose something valuable for you. kWh also matter MUCH: personally I can potentially produce just few gram…
kWh matters MUCH to you, not to reasonable people. If you need more H2, use a better electrolyser, or add another panel or two. The fact is, your numbers are all way off, so do not produce sensible judgments. They make you seem nutters. Get better numbers.
"my numbers" are not mine, but from the current state of research on the field. The current state is simple: we can produce green hydrogen but in too little quantities, that means:
- we can't use it on scale
- there is no point in using it at smaller scale
That's why kWh count, because panels are not "toll free" coming like fruits on some tree branches, they have to be produced and they have a cost. They have a usable life, they need to be decommissioned after that. Actually we can make a single family home hydrogen+p.v. in certain area of the world, such home will cost few MILLIONS, need a variable amount of land from an hectare to few hectares, and last at around 10 years without special maintenance. We can produce few of them for the 1% of the humanity. Unfortunately such humanity can't keep up the species nor can't produce the aforementioned tech in their backyard, that's is. Is it more clear now?
We can do many things in general, some can scale, some can't, some are reasonable some are not. A green hydrogen industry so far is not reasonable and can't work on scale. We can continue researching on it of course, but we need working things, not dream, so we need something else to keep up.
