We literally have the infrastructure to store TWh of methane, so we have already built at the necessary scale in the past. It is also not terribly complex to store hydrogen if you're okay with losing a few percent per year. You might be thinking of cryogenic hydrogen storage, which is definitely not the plan.

Everything is simple if you ignore everything. Because in the mind of renewable proponents all that grid-level storage is either already available or can be easily and cheaply built, no biggie.

"We have existing infra" ignores that this infra took decades to build.

"We know how to build" ignores that the storage costs can vary between 7 EUR/kg and 1040 EUR/kg [1]

and so on and so forth.

The capability for wishful thinking in renewable space is staggering.

Note: no one is saying it is impossible BTW.

I don't think anybody ignores the costs. It's just that every other option is more expensive.
