just use excess electricity to make hydrogen. This actually solves the intermittency problem, among many other things that will require hydrogen in order to reach zero emissions.

People are going with batteries and demand-shifting first because they’re more cost-effective when it comes to dealing with a few hours of storage. Hydrogen storage is mostly a contender for longer-durarion storage

For a few hours, yes, but that will make up a small percentage of total energy stored. To really solve the intermittency problem, you will need large scale energy storage.

You do need some amount of long-duration storage, with the amount depending on how generation diversity and how much clean firm generation you have, but we are still in the early stages of it.

The more renewable energy you have, the more you need long-duration energy storage. You cannot reach 100% renewable energy without huge amounts of it.
