It's a relatively less evil, for now. We still haven't found a good way of dealing with old batteries and it's a huge environmental problem.
- guitarbill 9y agoDo hydrogen fuel cells have major issues, other than the chicken-and-egg problem of hydrogen refueling stations?
- _ph_ 9y agoHydrogen fuel cells use about 3x the electric energy vs. battery powered cars, if you create hydrogen via hydrolysis. It is not only the energy used for creating the hydrogen, but also the compression and transport of the hydrogen is using a lot of energy.
- speedplane 9y agoExpensive materials (platinum) and difficulty making them small enough for a car.
- czechdeveloper 9y agoIs hydrogen low stability and easy leakage not an issue anymore?
- speedplane 9y agoFrom what I understand, it's handled by well placed fuel tanks, where even if they blow, no on inside the vehicle gets hurt.
- anubisresources 9y agoHydrogen is a non-starter. Many leakage, cost of energy, risky transport issues to overcome.
- javra 9y agoThere's also ground transportation by tram, no batteries needed.
- gozur88 9y agoCan't we recycle old batteries? The starter battery in my IC car is recycled.
- namlem 9y agoOld cells get reused for stationary storage until they degrade even further, at which point they can be recycled.
