Again, this is not about the production price of renewables, which is low and falling quite predictably, but the unknown long term costs of integrating substantial intermittent production into the grid.

Believable models of achieving that goal call for setting up capacity markets where traditional suppliers are paid to not emit, and stand by to intervene when required by weather conditions, achieving close to net zero year round emissions (¹. Nobody really knows how this will end up costing because no such grid exists today.

Grid scale battery storage is still very far from competing with traditional baseload production, even when supplied with free renewables. Sodium has been the next big thing for the last decade, but its only deployments are in the experimental, MWh range. It's still far from a mature, proven technology, let alone one that can disrupt lithium in the gridscale storage space.

Perhaps you are handwaving substantial technical and economic details away and making too bold claims insufficiently supported by data. Not unlike the nuclear fanboys who are seeing thorium fast breeders just around every corner.

(¹ Btw, this is just another nail in the nuclear coffin - coal too - because they can't play nice with a fast moving grid.
