Why? Electric cars don't use a mixture of gas and batteries. Those cars do exist and we call them "hybrids". But those are not carbon neutral and we don't pretend they are.
The goalpost never moved. If you want to use hydrogen storage in a carbon neutral grid you need 100% hydrogen fuel. We're not there there yet. And we won't be there for the better part of a decade, or longer. I guess…
Most companies are targeting hydrogen gas turbines to be produced in 2030 or 2040: https://www.siemens-energy.com/global/en/news/magazine/2019/... They aren't "off the shelf" technology yet.

If we aren't using combined cycle gas turbines round-trip efficiency of hydrogen storage is seriously reduced. I'm not moving any goalpost. This is your comment when you claimed that gas turbines could be repurposed to…
Sure, we could burn hydrogen and drive a boiler like a coal plant. But that's not where this comment thread started. > Those gas turbines you're referring to can simply be modified natural gas gas turbines Sure, if you…

That link you provided doesn't encompass gas turbines. Gas turbines capable of burning hydrogen do exist, but only at smaller concentrations, 70% methane and 30% hydrogen or less.
Then our transition to solar + wind needs to include the cost of installing a septic tank and water reservoir in every household. And a thermal battery for heating. And an electric battery for lighting. And all the…
Storing hydrogen is only one piece of the puzzle. Yes, if you happen to live near an abandoned salt mine that's a convenient place to put a large quantity of hydrogen. That doesn't solve the problem of massive…
We've been using hydrogen in the chemical industry. We haven't been using hydrogen to drive combustion turbines very much, and even then it's in a mixture of natural gas. Unfortunately, those alloys that experience…
That "manipulation of hydrogen" mostly involves use in the the chemical industry. We don't use hydrogen to power gas turbines. I'm not sure why you're trying to deny the existence of chemical facts:…
Name one hydrogen electric grid storage facility. Not prototypes, but actual commercial facilities connected to the grid. You insist that hydrogen is so technically ready, yet nobody is using it.
No, hydrogen rapidly corrodes any metals that it comes into contact with. If they are interchangeable, expect drastically smaller service intervals.
No, you have salt caverns with a volume sufficient to accommodate a lot of hydrogen. Actually implementing such a solution involves massive scale electrolysis, and either massive scales of oxidation cells or gas…
There are rarely shortages of electricity in the US. There were some in California during Covid, and the state had to do rolling blackouts. But no, there are rarely shortages of electricity. Yes, someone could use more…
And are we currently using any of these caverns for electrolysis and grid storage? All you said is that we have a big cavern that we could fill with hydrogen. I'm asking if anybody is actually building hydrogen grid…

None of those other battery chemistries are seeing the massive growth that lithium ion batteries have experienced. The nuclear "stans" are just pointing out that these are potential solutions, not actual solutions. If…
