>The main problem with replacing a fossil fuel plant with renewable + batteries is finding a battery system that can hold energy over a sufficiently long period of time and has enough capacity to replace solar/wind when it is dark and calm.

Synthesizing gas seems like a good solution. With electricity prices often dipping into the negatives thanks to all the renewable fluctuations, synthesized gas should be able to compete with any other base source on price.

Generate gas when electricity is cheap enough and use it to generate electricity when it's expensive enough. Basically a profit-pump once the initial investment is paid off.
