It is significant focus on the electrification of transport. Car-makers roll out a number of new models with battery range similar to Tesla.
Even planes are assumed be electric in few years on shorter routes.
On the other hand hydrogen is again focused as a storage medium for excess renewable energy production and possible use in transportation.
There are concerns about the environmental impact and many raise the question: "how-green-are-electric-cars?" An example is found in the link below.

What could be the development and final solution for the segments: Cars, trucks, buses, marine and air transport?
Do you foresee any breakthrough of alternatives?
Hydrogen electric vehicle is carrying his own power plant on his luggage together with the energy store and power machine.
First hydrogen is to be transformed to electricity and in the second step the electric energy converted in to work. This seems to carry an unnecessary load. In my opinion the batteries will be ready for longer ranges and quick charge soon.
Dear Olav
Yes, in my opinion Hydrogen operated vehicles are better suited for long ranges I believe that that is the future.
It is true, as Ali says, that you need to have a mean to produce energy, the electric cell, however the utilization of electricity available in the case of batteries or generated in hydrogen cell have the same consumer: the electric motors that move the wheels
Also you need an extra space in the car to storage the hydrogen, perhaps, albeit I don't know it, the hydrogen tanks can be located in the lower part of the vehicle as the batteries.
In both cases, energy needs to be spent in the production of hydrogen and in charging the batteries
However, it appears from my perspective, that batteries have the advantage of using energy produced by the car when desaccelerating or braking, and I don't know if the same can be applied to hydrogen cells.
However, the very large advantage of the hydrogen cell is for large distances, since the hydrogen tank can be probably completed in the same time that it takes now to fill a gasoline tank. However, both cases, cell or battery are conditioned to the existence of refilling and charging stations.
From this point of view the battery needs some time to be charged from several hours to may be 25 minutes.
Another factor to consider is weight. It rests to be see, which is lighter the battery or the cell
Regarding how green both alternatives are all depends on the generation source. If both use hydroelectricity, they are the same.
