Hydrogen cars are so popular. See all of the people queuing up for miles to fill up their invisible hydrogen cars

LOL
Unless the hydrogen can be generated using renewable energy hydrogen cars still cause the same pollution as other cars. Since they are a form of ICE then they spew out nitrous oxide like petrol/diesel cars.
Totally pointless. EVs are the future.
It depends on what you environmental concerns are. EV create a lot of pollution in the form of their production and their batteries, but it's not Carbon. They also have a lot of limitations with range etc, which I'm sure will continue to improve, but at what cost (again the waste products from the batteries etc).
I don't think there is any one size fits all solution. Today, EVs are the way to go. Tomorrow, if we can reliably source the hydrogen, it's the way to go.
But none are without any downsides. There were food supply concerns when ethanol started increasing in popularity because it was worth more as a fuel source to the supplies than as food.
That's all changes now, but what other consequences would there be to HV?
Water is already far too precious for life, let alone needing it for refining into a fuel source. Yes, there are prototypes that use sea water rather than freshwater but knowing us humans, do we really need to put the our seas in even more stress?
I don't think we should be arguing about which tech is the best, why can we support the best tech for the best solution, even if it's a mixture of both?
