Hydrogen fuel distribution and storage for cars
One of the big problems with using cars that run on hydrogen is that the infrastructure is not in place to distribute hydrogen. Meaning there are not gas stations to stop at to fill up with hydrogen.
Gas/Propane is being distributed (at most convienence stores) around here in full tanks. You just bring in your empty tank and trade it for a full tank. And pay for the difference (the gas/propane).
Why not do the same thing with cars.
Standardize the fuel tanks so that every car uses the same tank.
When you need to refuel, you just pull into a place that sells these ready filled tanks. You trade your empty tank for a full tank. Each car could have two tanks. When one runs out, the car would switch to the other one and you could then stop and trade out the empty tank.
This way, a lot of stores could offer hydrogen without having to upgrade their equipment. Just have to add storage for full and empty hydrogen tanks. Then sell them just like stores sell full propane tanks.
I think this would solve most of the problems with hydrogen fuel distribution.
What do ya'll think. Add ideas to this.
