Solve two problems at once, & create a few, very large, pumped storage power stations !petej wrote: ↑Fri Aug 26, 2022 2:38 pmGood post. Storage can also be in the form of hydrogen. Baseloading nuclear and when excess electricity is present use it to charge batteries both electric and heat (short term storage) and generate hydrogen (longer term storage).Dinsdale Piranha wrote: ↑Fri Aug 26, 2022 12:50 pmMassive renewables expansion won't make things cheaper, or more reliable. On its own it will do the opposite. The only renewable without intermittency issues is biomass and that's not a scaleable solution, in the UK at least.
For every GW of wind/solar you need a GW of reliable power on standby. Currently this is gas. The less gas you use, the more expensive it will be to have it on standby.
Nuclear is reliable, energy dense, and doesn't have intermittency issues. Thing is, if you've got nuclear then there's no reason not to run it flat out all the time. Costs the same either way so it's only really appropriate for baseload so once you've spent the money it will reduce the demand for renewables.
Wind has some good potential for demand that can be time shifted - think charging your EV when it's windy at night - home batteries can also benefit from this. You can't use it for anything you need to rely on.
We basically need grid scale storage. This is an unsolved problem and there isn't anything coming in the near term. Until then, wind/solar have to be backed up by something else - at a cost.
You create some reservoirs that are badly needed, & you get significant power storage capacity on your grid.
