yes

No.

Very expensive and inconvenient.

so “traditional” fossil combustion electrical generation is shit

So why are they using them in the UK?

It doesn’t make up any significant part of the UK’s storage. Capital costs per kWh are around 100 times higher than lithium ion.

what if fossil powered spinning flywheels already exist

But (from my very brief investigation of this subject) they aren’t used for storage. They are used to smooth out short term fluctuations in demand, which since the UK is heavily investing in them, I presume they do efficiently.

How they work better than batteries for this, I have no idea.

wait how do components smooth out fluctuations without functioning as storage

OK, make that only for very short term storage then.

we thought (from reading elsewhere) the whole (sensible, as opposed to undecided) argument about this was that massive flywheels already exist in “traditional” fossilburning electrical generators, and were responsible for a fair part of the surge resilience of the “traditional” grid (as very short term storage), and so the massive flywheels part of it could simply continue with a modification that they run as motor-generators rather than turbine-generators

Could well be. I thought they were installing new ones, but I may have that wrong.

maybe, we just interpreted the video as drumming up the benefits of flywheel like an entrepreneur with manic psychosis so took it with a flake of lithium more than as actual SCIENCE supporting their widespread use, but then again we tend to trust all online video about as much as that

speaking of lithium disclaimer we’r‘n’t saying that flywheel are any better than lifepo battery
