The article says that the ‘breakthrough’ is a turbine that runs on 100% hydrogen rather than a mixture cut down with natural gas. The article doesn’t say why it is necessary to dilute the hydrogen with natural gas.
Could it be that pure hydrogen burns too hot and damages the turbine? Could it be that pure hydrogen’s hot burn creates polluting exhaust gases such as the Nitrous Oxides?
The article says, “It uses two complementary methods to achieve the high operating temperatures while maintaining very low emissions and requiring no diluents.”
What are the “complementary methods”.
As other posters have asked, “Where does the hydrogen come from?”
Could it be that pure hydrogen as opposed to a mixture causes too much wear through metal embrittlement!
