Electrolysers are (for now) slightly more mineral limited than batteries and don't last as long. Both are valuable enough to recycle, and both are having a lot of work being done in finding abundant chemistries. Batteries are further along on the latter. Western australia has good enough solar resources that they could in theory use a heat based hydrogen production method, but that is more logistically difficult. TL;DR Hydrogen isn't for electricity, it's for ammonia/steel/polymers/etc and the stores of various hydrogen compounds created for those purposes are your emergency backup for the month long dunkelflaute if it ever manifests
