Nonsense.
The core issue is grid-scale storage. Adding 10 or 30% renewables is easy and is where we currently are, getting to 100% means we need to solve that technology issue which we don't currently have a solution to.
Nuclear + renewable is the current way to de-carbonize the grid. Build both heavily until we solve the technological issue with grid-scale storage in the coming decades.
Couldn’t we pump water into dams during times of surplus and then drain the dams for hydroelectric when needed? Is that not feasible at scale?
Not everywhere has the geography to dam and use water like so. But there's other non-lithium energy storage methods in the works.
Off the top of my head, concrete blocks, compressed air, liquid metal batteries, heat batteries, and flywheel based energy storage.
There's more too, if you're curious.
