You may prefer the term ‘Other’ used in @davidosmond.bsky.social’s weekly models of the main Aust network. This is ‘firm’ energy of last resort - always available as long as req'd.
Firm/Other energy will evolve as he (& Zero Lab) describe but won’t be chem batteries.

Thread: Each week I run a simulation of Australia’s main electricity grid using rescaled generation data to show that it can get very close to 100% renewable electricity with 24GW/120GWh of storage (5 hrs at av demand)
Results:
Last week: 92.6% RE
Last 247 weeks: 98.7% RE (1/6)
