If those solutions were viable at scale then countries like germany or england using lot of renewables and coal (gas or gb) would have been using them already.
They'd only be using them now if they cost less than gas + current carbon taxes.
The question is: at what level of carbon taxes would nuclear displace gas, vs. what level would renewables + storage displace gas. In the US, CO2 taxes would have to exceed $300/ton for new nuclear to displace gas CC baseload, and for intermittent applications the needed tax would be far higher.
