Gas turbines have grown into a hallmark of the modern power system for their high efficiency, reliability, operational flexibility, fuel flexibility, and low-emission power options. But if gas turbines are to remain relevant amid the anticipated proliferation of renewables, energy storage, and decarbonized gas—including hydrogen, ammonia, synthetic methane, and other green fuels—research and development (R&D) to enable emerging applications must be a high priority, the global gas technology industry concedes.
