Completely agree!

Tidal could be great, but keep in mind that it's not 24/7 since the tides have very prominent ebbs and flows, so there are two times a day (not quite) when it hits zero. OTOH it is extremely predictable & independent of solar/wind.

True we can't consume, store or transport all that's made at certain times. For solar those are midday in a very few locations…which also use fossil fuel during the rest of the day. For wind it's mainly a grid problem.

Yes, batteries are needed for storing solar & we need to shift consumption, too.

Maybe link to the person who's actually the owner of image, huh?

fix the grid or shift demand. The latter is what Oz is trying to do with the free 3 hr of electricity during midday. But they still burn a lot of coal, so—to repeat—there's no excess.

It'd also be a big investment to make (costly) green H from what will soon be needed (direct) electricity.

There is no excess electricity, from solar or otherwise. Pretty much everyone burns fossil fuels to some degree & we haven't even fully electrified.

There is inadequate grid support & demand, which leads to curtailment midday in places like Australia. The solution isn't make hydrogen w/it, but...

Where to start?

There is such a thing as recycling.

Also HFCs typically have batteries in them, like the Mirai.

EVs have no emissions.

Where do,you honk hydrogen comes from?
