You beat me to it. IF the process could be made efficient enough then it could be used as a means of storing excess energy generated from a nuclear power plant. It can never be used to generate power, however, since it will always take far more energy to create fuel than can be recovered from the fuel.
By the way, I learned how to create clean burning pure hydrogen out of water back in my high school chemistry class 40 years ago. This is not new technology.
Yep, me too. Too bad it's nearly impossible to store.
