Nuclear is as capable of rapid dispatch as coal was and coal ran the

You can store a lot of energy in a big steam boiler

And in the UK we have enough hydro to cover the intermediate
dispatch requirements.




We were discussing high capacity , do keep up.

You really dont understand the subject do you?

Very short term dispatch is catered for by the rotating masses of the
turbines: That covers a powerstation tripping

Minute level dispatch is catered for by hydro and steam in boilers.
hpor level dispatch is catered for by turning the nukes up and down.
Or having some gas.
Renewables contribute zero to all of this and batteries and hydroigen
are an expensive inegffficent (and dangerous) substitute for pumped
storage


Pumped storage only lasts for hours, this is not enough to cover
extended periods of excess demand.

SSigh. Thats why you have dispatcahable nukes

Hydrogen offers the potential to
provide months of storage.

And I have pointed out the unbelieveable risks and costs assocaited with
that incredibly stupid iudea

Hydrogen is expensive but if you have over capacity you might as well do
something with it. We do not have enough mountains to pump water up.

We do actually. Just.

In the end its all cost benefit analysis driven. How much do you value
CO2 emission at? The higher the cost of then the more nukes and the less
gas power. *Renewables are never the cost effective option*, ever.
