That article summary says:

and
> satisfy countries’ electricity demand in 72–91% of hours (83–94% by adding 12 h of storage).
So not 3 hours and still significant number of days without power.
- pfdietz 5y agoYou back that up with combustion turbines burning some renewably-sourced fuel. Capital cost of a simple cycle combustion turbine power plant: $500/kW Capital cost of a nuclear power plant: $10,000/kW So, one can have this backup sitting there ready to go for just 5% of the cost of an all nuclear grid. You do need the fuel, but if it's only used a few hundred hours per year the fuel cost will be minor.
