It also doesn’t state what is obvious to those of us who build infrastructure: Germany and Denmark have no way to store wind power so it has no choice but to pay others to take it. Norway is home to one of the worlds largest batteries.. its hydro power. Already cheap, but has the added benefit of being storable for sufficient duration to take german and danish wind power when it suits them (ie when they get paid). It baffles the mind why the danish and Germans don’t use some of their subsidy to invest in storage — but therein lies another catch 22. The lithium needed for that isn’t being mined in sufficient quantities in Europe and 100% of the supply from China is earmarked to autos. There are some jr mining countries spinning up in Europe but it will be awhile before any meaningful impact will be felt. One wonders if by then other storage techniques will be viable. In the meantime, they will be forced to pay the Nordics to take their green energy while supplementing with coal from Poland or succumbing to the siren call of another controversial Russian pipeline.
- atoav 7y agoI recently listened to a long podcast with a German that is working on hydro-gravitational storage with water lifting a huge (multiple hundred meters in diameter) rock cylinder to store energy. He recently finished a smaller scale prototype (if I recall right 20m diameter) that tests all the insulation, the cutting techniques and power generation
