If solar were free, but we still needed to pay for battery storage, how would it then compare in cost to fuel-based alternatives (fossil fuel, nuclear etc)?

Not all battery storage needs to be electrochemical - hydroelectric dams work amazingly as pumped storage batteries (although site specific).

And the same concept as pumped hydro can by applied in other ways that don't require a waterway or quite as much physical infrastructure, https://www.vox.com/2016/4/28/11524958/energy-storage-rail is an example.
