Perhaps they discovered the most efficient way to achieve hydrolysis of water into H2 but I am guessing that  any generators will need to use hydrocarbons with H2 injection. Maybe they've achieved a process that isn't combustion, so CO2 isn't emitted?  Clean coal, anybody?

Regardless, laws of thermodynamics apply so I am a little worried about this given the risk that it might not pan out.
