if we used electricity to separate water into oxygen and hydrogen. Could we use hydrogen and somehow set it to a positive or negative energy set? After that, the we would heat it up so the atoms are moving so fast that they hit into each other creating friction or heat. Is this another way of fusion reacting.

Water molecules can be broken down into hydrogen and oxygen molecules by a chemical reaction called electrolysis. When an electric current is passed through liquid water (H2O), it changes the water into two gases—hydrogen and oxygen. The molecules of water break apart into individual atoms.
