> And the economy is based on using "waste" renewable energy. The problem is that solar panels and wind turbines don't produce energy when we need it the most (see: duck curve). The idea is to store that energy as hydrogen and use it in vehicles. I've seem this statement loads of times before. But actually, Hydrogen production is not economical if you do not produce it continuously. Meaning, it does not make economical sense to only use excess energy capacity. Further, Hydrogen for cars is highly inefficient if you take all of the steps into account. For the foreseeable future the common expectation is that Hydrogen is produced from fossil fuels (e.g. read forecasts from analysts or companies such as Shell). This while at the same time they pretend it'll make this more green. Hydrogen is already produced in huge quantities btw, but it's somewhat hidden as it's used by industry. Meaning, most people wouldn't even notice it. Unlike e.g. seeing a new hydrogen gas station.
