Gas turbines play a central role in power generation and will become increasingly
important in supporting renewables, ensuring grid stability against their
intermittency. Hydrogen, with its CO2-free combustion, is considered a key enabler
for decarbonization, but its high reactivity challenges conventional combustion
systems and limits performance. Ansaldo Energia’s GT36 gas turbine addresses this
with Constant Pressure Sequential Combustion (CPSC), a technology that combines
two complementary combustion stages (flame propagation and auto-ignition)
allowing high-temperature, low-emission operation with exceptional fuel flexibility.
The talk will present the CPSC concept, its advantages for hydrogen combustion, and
provide an overview of Ansaldo Energia’s combustor development and validation
processes.
