Gas Turbines

In order to mitigate CO2 emissions Zero Emission Power Plant concepts are being explored on a global scale. Gas turbine based configurations are playing a significant role in these scenarios.


Following up on the previously conducted collaborative effort on “Hydrogen enriched Lean Premixed Combustion for Ultra-Low Emission Gas Turbine Combustors” the future collaborative task activities on gas turbine combustion issues should be linked to respective Zero Emission Power Plant concepts.


In future energy scenarios renewable energy resources (wind, solar) will play a much more significant role than in the past. As these resources do exhibit a weather dependent fluctuating non-controllable energy source (for electricity production), it is indispensable to have additionally controllable electricity production technologies available which can compensate the variable electricity production from wind & solar, in order to keep the electricity network stable i.e. to maintain the balance between production and consumption of electricity. Even with large electric storage systems hopefully becoming available in the future as well, flexible controllable electric power generation technologies, like gas turbine power plants, will be still required to provide sufficient generation capacity necessary to maintain grid stability and security of supply for electricity.

Fast response characteristics and large load gradients do pose a challenge for the safe and stable operation of the gas turbine combustion system. Burner and combustion chamber design need to be adapted in order to be able to cope with such load changes without jeopardizing the performance (efficiency, emissions) of the gas turbine engine and the integrity (with respect to thermal and mechanical stress) of the hot gas path components.
