    Did you miss the word theoretical? And yes, AFAIK we are already storing some but certainly not at the scale required if that’s even possible (I wouldn’t want to live anywhere nearby a huge storage of hydrogen). Another related advantage would be the transport of stored hydrogen where transferring electric energy comes at cost when it comes to long distances.

      No and there is no theoretical nor a practical advantage. Throwing in the word “theoretical” to make a wrong idea sound valid doesn’t work with me.

      A gasoline range extender makes more sense than hydrogen.

        Gasoline in the EV? That is the worst combination. Also we are storing hydrogen today, so it works to some degree.

          No true. That’s way more efficient than hydrogen and the gasoline could be substituted by ethanol.

            Hybrids are perhaps worse than both ICE and EV. More complex, burns more than the other two, still consumes a shit ton of oil and pollutes a lot. Ethanol has also its problems, like how does one get it in enough quantity. Why do you think we are not driving ethanol cars today?

              Why do you think we are not driving ethanol cars today?

              because oil, and gas companies pay government to keep you their bitches.

              Many countries, like Brazil, run cars on pure ethanol, and this makes it a competition to gasoline, which gas companies hate. Over 83% of new car sales in Brazil are flex-fuel vehicles (FFVs) capable of running on any blend of ethanol (E100) and gasoline. While the majority of vehicles are capable of using high-percentage ethanol, actual consumption varies, with nearly all gasoline in Brazil currently blended with 27% to 30% anhydrous ethanol.

              And ethanol engines run cooler, and last longer because they burn much cleaner.

                That’s certainly a part of the reason. But I guess a bigger issue is ethanol production where you’d need large fields for “growing” ethanol instead of food. And lastly, it still produces co2.

              Yes a hybrid is more complex but less so than hydrogen because the engineering problems of hydrogen haven’t yet been fully solved (storage that doesn’t use more space than battery or tank).

              It’s an upgraded ice.

              EV with range extender is not hybrid. You keep confirming that you don’t really know what you’re talking about.

                Range extender doesn’t make sense which is while serial hybrids died out for cars. At the rpms where gas is most efficient, it’s better to drive the wheels directly with the ice than waste energy converting it to electricity with a generator and back into motion with the ev motors.

                That’s what all hybrids do today.

                  also doesn’t pollute, right?

                  You make no sense. Of course a range extender pollutes but it’s an edge case only for very long distance drives.

                  Manufacturing hydrogen is way more energy intensive and pollutes much more.

                    In what way hydrogen manufacturing pollutes much more assuming we are talking about green h2? Sure renewables have a pollution cost associated with manufacturing but I really don’t think the end result is much more pollution. Even less so in the cities in resulting co2 and pmN emissions.
