The Gas Turbine’s Path to Zero Carbon
Kellen Walters, Mitsubishi-Hitachi
As society decarbonizes power generation and transportation, the path toward gas plus renewables and storage is becoming clearer.  The type of fuel used for power generation has a profound effect on carbon emissions, and flexible high capacity technologies that can back intermittent renewables become more important.  

Excess electricity from solar, wind, and other variable renewable energy sources can be used to create renewable hydrogen through electrolysis.  The resulting hydrogen can then be stored and used as a dispatchable carbon free power generation or transportation fuel when needed.
