Japan invented "using water as automobile fuel"! ! What exactly is going on?

This is absolutely false news. When hydrogen and oxygen react to produce water, energy is released, so it is necessary to absorb external energy to decompose water into hydrogen and oxygen. It is said in the news that it is absolutely impossible to decompose water into hydrogen and oxygen without any electric energy. I am a professional manufacturer of hydrogen production equipment by water electrolysis. As far as I know, the United States and Canada are more advanced in this respect in the world, and even China is better than Japan, so it is no match for Japan.
