Direct conversion of nuclear heat towards hydrogen gas by way of sequential thermo-chemical transformations has been studied for years. Google around, you'll find plenty on it.
Such a system is many, many years away... just on the politics alone.
The next BIG thing is not hydrogen but Compressed Natural Gas (CGN). Honda is ALREADY selling a car build to run ONLY on CGN through their regular dealer network. You can go down right now and buy one.
CNG powered vehicles cost about half as much per mile to drive based on todays price spread between gas and natural gas. And yes, road tax is collected at the CNG pump. UPS has long converted their fleet, and normally will let you fill up at their system -- in their off hours, only. Other fleet refuelers are expanding all over. A major one is in Rancho Cordova, CA... South of I-50, east of Sacramento.
Electric vehicles are going to come like an express train in urban areas. They excel in heavy traffic: being stopped does not ruin their fuel economy.
You can expect that within ten years 400 Amp 240/120 single phase service will be the norm in upscale new homes. More than one EV will need charging.
At the current time Saudia Arabia, Kuwait, Iraq, Iran and others are FLARING ( burning it off to get rid of it ) enough natural gas to cause the oil markets to crash. ( If the energy was made available to motorists globally.)A
At some juncture, a global grid of natural gas pipelines will permit this gas to be sold into the global marketplace.
In the near term: the MASSIVE natural gas deposits ALREADY available in Alaska ( equal to three times the energy content of the North Slope oil deposits ) will be brought down to the lower 48 within the next twelve years.
As the vehicle fleet shifts over to CNG and electricity gasoline demand will drop. The price surge of the last two years is already causing noticeable drops in motor fuel demand.
As electricians: study up on Division 1 Code issues. Many new CNG distribution facilities must be built.
Get prepared for a whole new round of 'heavy-ups'.
