Xoa- That's an important question, because there has been a lot of
loose talk from politicians making it sound like we can substitute
hydrogen for fossil fuels.
You can use electrical energy to separate water into hydrogen and
oxygen. That doesn't generate electrical power but instead uses it up.
You can then recombine the hydrogen and oxygen in a fuel cell to
make electrical energy. The amount you make will ALWAYS be LESS than
the amount you initially put in to make the hydrogen. That's due to the
laws of thermodynamics, which cannot be repealed by any government.
