I don't see why? Germany is part of one of the biggest most diverse synchronised electricity grids in the world - it sits at the centre of an international transmission system stretching from Ireland to Turkey and from the artic circle to Morocco. Germany has no need to store several weeks of electricity when it can just tap its neighbours when it needs to. In reality, generally Germany has been a net exporter of electricity.

> Germany is part of one of the biggest most diverse synchronised electricity grids in the world Germany needs about 300GW in winter once it switches to electric heating and EVs. In winter, renewables regularly drop to about 10% of their average production for weeks at a time. So Germany will need to import about 250GW of power from its neighbors. That also need power for their own use. This is just not feasible. So the plan right now is to replace the coal generation with natural gas generation, and color the pipes in green paint. Oh, and make the companies to pinky-promise that they are "hydrogen ready".

  Covestro, a German company, already has a signed contract and made advance payments to receive the equivalent of up to 100,000 tonnes of green hydrogen (GH2) per year commencing 2025. A kilogramme of hydrogen - the unit most often used – has an energy value of about 33.3 kWh.[1] So a tonne of hydrogen delivers about 33 MWh and a million tonnes about 33 terawatt hours (TWh). To provide a sense of scale, the UK uses about 300 TWh of electricity a year. ~ https://www.carboncommentary.com/blog/2021/6/11/some-rules-of-thumb-of-the-hydrogen-economy https://www.carboncommentary.com/blog/2021/6/11/some-rules-o... It takes a good while to build out the physical infrastructure to deliver green hydrogen equivilants: Green hydrogen is made from renewable energy, producing zero pollution – its only by-product is steam. FFI’s ambition is to grow its green hydrogen production to 15 million tonnes of green hydrogen per year by 2030, accelerating to 50 million tonnes per year in the next decade thereafter. ~ https://fortescue.com/news-and-media/news/2022/07/05/fortescue-future-industries-and-covestro-announce-plans-to-enter-a-long-term-green-hydrogen-supply-agreement-2022-01-17 https://fortescue.com/news-and-media/news/2022/07/05/fortesc... The person doing this isn't in the "pinky promise" game, they built out a penny stock company from 2c a share to ~$28 a share over two decades to capture a large chunk of a billion tonne per annum raw iron ore market.

  You’re criticizing German for not already having the capacity in place to meet a future demand? It’s not enough that Germany is currently a huge net exporter? “So the plan right now is to replace the coal generation with natural gas generation, and color the pipes in green paint.” - eh no. This is not “the plan” although getting rid of all coal is part of the plan.

So basically, Germany is _paying_ companies somewhere around $20B to build new gas power plants and make _plans_ to switch to hydrogen by 2032. The switch itself can go into 2040-s.
