But seriously, hydrogen is an energy storage means. There is a new pressure swing absorber being developed which will allow 50kg of hydrogen to be stored in a reasonable size at only 1800 psi. Normally, you need 10,000 psi. This is enough hydrogen to make a Tesla go at least 800 miles. With the weight reduction in the batteries, it might even be further.

It is possible to turn methane into hydrogen, but the end energy usage is about the same as an ICE CNG system.
