  • Oh yes, no argument there. We’re already using absolutely huge amounts of hydrogen that are mostly made from fossil fuels right now. Worldwide hydrogen production is responsible for more greenhouse gas emissions than the entire country of Germany. We’ll have to turn that into green hydrogen and use a ton of renewable energy for that. If we make use of surplus wind and solar, it will help a lot with stabilizing the grid.

    What I was thinking of was the idea of producing hydrogen through electrolysis, storing it and later turning it back into electricity through fuel cells. And I’m not sure if that will ever be cheaper and more efficient than newer and cheaper battery technologies like sodium ion or redox flow batteries.





  • Your second paragraph could be summed up as: we chose the destination years ago, so there’s no point changing course.

    Which makes perfect sense when you consider that there’s a deadline, we’ve gone a very long way in one direction and going all the way back to take another route would guarantee missing that deadline.

    It’s like you’re taking your ship from China to Rotterdam, you’re past the Suez canal, in the Mediterranean and now you decide to turn around and go around Africa after all. It really would be idiotic.






  • That is just misinformation. First of all, nuclear power never contributed that much anyway. If all nuclear power plants ever built in Germany were running at full load 24/7 for 365 days of the year, they would produce 231 TWh, which is less than 10% of our total energy demand. So there was never that big of a hole to fill in the first place. Especially in the last ten years, when only a handful of power plants were still in service.

    In reality, renewables have managed to replace both nuclear power and a large chunk of fossil fuels (source). Last year we had to export enormous amounts of energy to France, because their nuclear plants had proven so unreliable (source). This has admittedly led to an increased use of fossil fuels, which we could have avoided by building more renewables here (or in France).


  • We are trying to get more heat pumps installed, but people are still proud of getting a new gas furnace installed in 2023, thus avoiding a potential ban and betting on guaranteed dirt-cheap natural gas for another 20 years.

    But either way, nuclear power is history in Germany and it makes absolutely no sense to bring it back. We never had a lot of nuclear power to begin with and the few power plants that could maybe be reactivated with a ton of money and labor are just a drop in the bucket. Building new reactors takes decades from initial planning to going live and nuclear construction projects are notorious for immense cost overruns. Plus, there are only a few construction companies in the world that have the capabilities to build a nuclear reactor and they’re already tied up in other projects. We would need dozens of new reactors built simultaneously and they would still be finished too late to contribute anything meaningful to a carbon-free electrical grid.

    At the same time, wind energy is a dirt cheap, proven technology that is much more easily deployed, scales really well, is decentralized and reliable. Yes, it can be intermittent but it’s predictable (weather forecasts exist). And if we had invested a fraction of the R&D budget for nuclear fission and fusion into energy storage technology, it would be a complete non-issue. We have some work to do in that regard, but sodium ion batteries are pretty far in development and should be much cheaper. Iron redox flow and liquid metal batteries also have potential, maybe hydrogen. Demand response will also be a big factor. With flexible pricing during the day, both households and businesses can save a lot of money by using more energy whenever there’s a lot of it and less when it’s scarce.





  • I don’t know. The way it’s going down, it really makes him look like an idiot. He could have just flipped the switch and turned it off as a massive demonstration of power.

    Instead he’s making one mindboggingly stupid decision after another, showing the whole world how utterly incompetent he is.

    The most logical explanation for me is the easiest one: if he’s making stupid and incompetent decisions, maybe he’s just stupid and incompetent.
