This is undesirable in the same way shipping water via trucks is a lot less efficient than using pipes. For some use cases where electricity doesn't work, trucks with e.g. methane could work. For everything else it's just way to inefficient to convert, store, transport and then convert it again. Same issue with hydrogen - from source to force applied in a car, it's 22% efficient, compared to 79% for an EV.
