Battery Electricity Storage being built in Scotland

[Hypnotic Chimera]

In a recent discussion we chatted about Net Zero and the need for fossil fuel to "fill in the gaps" when wind and solar weren't generating.

So how's about a massive battery storage facility that charges off solar and wind when excess is being generated:

Power for 3 million homes

Many will no doubt argue about the methods used to store energy but have been using pumped storage for some time.

Other countries have similar systems.
Battery storage is fairly new but several countries have started to install them to help mitigate “brown outs”. I’m not sure if it’s efficient but in Germany they have trialled using excess electricity to split water into Oxygen and Hydrogen and then burning it again as needed to produce electricity.

Home battery storage as part of solar panel installations is also taking off. Not surprising really as I don’t believe suppliers pay customers a particularly good rate when they export to the grid?

The cost of Gas (used to produce electricity in the UK) seems to steadily rise whilst the cost of Solar Panels and Home batteries seems to still be going down. Efficiency also seems to be improving.
