AthenaToday, Thursday, Germany will get 99% of its power from solar and wind.

Lorenz@eingfoan @Climatehistories What's the plan to get closer in the evening/at night and in winter?
Oliver SchafeldLarge scale battery storage facilities apparently are booming in Germany.

For future large scale storage salt caverns seem to present great opportunities. There are lots of them in Northern Germany where also most of the wind energy is produced.
Dmian 🇪🇺@lorenz @eingfoan @Climatehistories Batteries and green hydrogen are two solutions many European countries are exploring.
Basically Wind combined with pv is almost perfect since they are complimentary in profile. Nevertheless both are volatile and need either batteries or hydro pump to store over night and in times where there is limits.
Water by the river is almost like atomic plants and runs very consistently.
So all 5 combined intelligently can solve the problem but are hard to achieve in large scales.
Miha Markič@eingfoan @lorenz @Climatehistories *impossible to achieve in near future, the scale of energy storage is insanely large if you want to be fully on renewables
@mihamarkic @lorenz @Climatehistories
Yes and no
Germany nowadays has around 114 Gwh capacity in battery nowadays. Also pump hydro is expanding largely and currently is at 40gwh
So we can survive about 3 hours without any renewable theoretically

Interconnecting grids with HV DC transmitting lines can reduce the requirement for more localized storage. Such cable can run 1000s of km and could for example provide offshore wind energy from Newfoundland to Los Angeles.
That said the battery storage technology is improving faster than PV and we will see much more of it in the years to come.
@eingfoan @lorenz @Climatehistories 3hrs is nowhere enough, pump hydro can't grow more than that, batteries degrade, now is warm, people don't run heat pumps, days are sunny and long. You still burn quite a lot of fossil fuels and contribute a lot of co2. Or import from France, which is a bit hypocritical. 🤷♂️
@eingfoan @Climatehistories And during the winter when energy consumption goes up with heat pumps whilst solar hardly produces you'll need something more no?
@lorenz @Climatehistories at least water yes
