A comment on Nuclear energy is a vital part of solving the climate crisis. Parent comment
In investment and projects true, in technology no. It's just a bit expensive and politics..
Useful technologies (dramatic reduction of required storage):
* HV DC long-range transmissions (Russia)
* offshore wind (Hornsea)
* load scheduling (home dual tarrifs, remote-managed water heaters, regulated aluminum smelting, upcoming vehicle charging, ..)
* plain old overprovisioning
Slow Storage:
* electrolytic hydrogen stored in caverns (estimated cca 40% efficiency)
* automated train (cars) loaded with rocks on a slope (85% eff.)
Fast storage:
* batteries (Tesla)
* flywheels
Not that useful for scaling:
* pumped / regulated hydro - currently very important but scaling limited by geography.
