The Liberal Democrats said it was time for the UK to prioritise renewables, batteries and imports over nuclear.
Yes, dear, but how do you charge your batteries on a cold day like today with no wind and very little sunlight?

One option is gas- you can buy it from those friendly Russians/ Saudis whenever the price is low, and store it
no gravity needed like water ?
How about synthesising gas and petroleum ? Seems alot more economical
Can you imagine storing 6 months worth of hydrogen or batteries for the uk ?

Seems alot more economicalYes and no.It's more expensive and wasteful to synthesise more complex molecules.But it's cheaper in that the consumer already has equipment- cars and cookers- that use hydrocarbon fuels

Even England doesn't get 6 months of darkness.
Quote from: Bored chemist on 18/01/2019 18:47:27Even England doesn't get 6 months of darkness.Come now! Every point on every planet (except perhaps Mercury) experiences equal amounts of light and dark. It just happens that, at the poles, they come in 6 month chunks instead of 12 hourly samples.
Winter generation has twice the summer capacity,
find some way of running ships and planes from batteries
. I do like the idea of synthesising liquid fuels from wind electricity,
Quote from: Petrochemicals on 18/01/2019 20:56:11Winter generation has twice the summer capacity,So we build twice as much- because that's obviously much easier than storing 6 months' worth of energy.Why was this an issue?
Like i said we could synthesise alot of petrol at peak times.
There's another obvious factor you can bring into play.Diversity of supply.It's unlikely that it will simultaneously be cold, dark, drought-ridden and the tide's out all at the same time; and if they are then that's going to be a local phenomenon- so you set up a grid to transfer power from where it's available to where it's needed.Quote from: Petrochemicals on 19/01/2019 01:20:55Like i said we could synthesise alot of petrol at peak times.We could synthesise a lot more methanol (in energy terms).BTW "a lot" is two words.
