If only there were some way to take energy made from sunshine and store it in some form for later. Like in a battery. Or as heat. Or in a flywheel. Or just use the energy for something we’d really like to do as cheaply as possible. Like sequester CO2. Or desalinate water. Or run industries that would otherwise use natural gas.
Or use it to generate hydrogen for simpler, cheaper, more reliable, sustainable hydrogen powered cars.
We don’t even have enough lithium to replace the average country’s existing cars, let alone all of them, or literally anything else that requires lithium.
Isn’t one the issues with hydrogen motors that they are a bit explodey? Genuine question, haven’t looked into it in a long time.
Pure hydrogen doesn’t explode. It’s only if you mix it with oxygen. The Hindenberg glowed red not blue
From a grid stability point, you can’t produce more than is used, else you get higher frequencies and/or voltages until the automatics shut down. It’s already a somewhat frequent occurence in germany for the grid operator to shut down big solar plants during peak hours because they produce way more power than they can dump (because of low demand or the infrastructure limiting transfer to somewhere else)
Negative prices are the grid operator encouraging more demand so it can balance out the increased production.
