Not unreasonable, but I would point out two options (not the only):

1) "Water batteries" - highly efficient (far more than the 'chemical' you are apparently referring to) & responsive

2) Methods for using 'renewables' to produce &/ support production of chemical fuels - with the added draw / potential goal of 'closing' the 'carbon cycle'

As to #2, one of the ideals that has been kicked around for decades is to do something like: use 'renewables' to sequester CO2 from the atmosphere and convert it into something like butanol, for example.

Now, last I was up-to-date on any of this sort of work (~10+ years ago), the economics were not favorable. Certain types of commodity chemical production with 'biological basis' (another type of renewable, typically) had much more favorable properties economically. And, indeed, you do see, for example, (thermo)plastic products made from chemicals like "PLA" increasingly. But, the "biofuels" concept is / was much more challenging, especially as "fracking" technology made great leaps etc.

Nuclear has its pros and cons - blanket disavowal is fatuous. Nevertheless, there are substantially more options, systems, technologies, etc. in development and production than are often discussed in too many of the pro-nuke(s) / no nuke(s) 'sniping' chains that have been prevalent in society & on the internet since I was a wee tyke myself.

> use 'renewables' to sequester CO2 from the atmosphere and convert it into something like butanol, for example.

are you referring to P2X? I think P2X is an awesome solution for existing infrastructure, but it's obviously not particularly efficient. I am excited about pumped storage as well, but my fear there is we'll run out of sites, and obviously the 80% efficiency is still not ideal.

By no means am I arguing nuclear is a one size fits all solution.

"Highly efficient" is very vague.

What matters here are the numbers:

W/$

J/$

% round trip losses

% losses per hour

Number of cycles before replacement needed

Response time

Do you have them?
