128517 - 100% H2 DLE Gas Turbine Combustion Technology Platform Development 

Siemens Energy is developing the required technologies to operate its gas turbines on up to 100% H₂ by 2030 to support the target of limiting global warming to 1.5 degrees Celsius. A focused effort has been undertaken to develop a combustion system technology platform for the complete Siemens Energy gas turbine portfolio which will enable gas turbine operation across the entire range of H₂/natural gas blends within emissions compliance. The world’s first engine demonstration of these technologies in an industrial application running with 100% H2 has been conducted in an SGT-400 engine in 2023 as part of HYFLEXPOWER project.

This paper will present an update of Siemens Energy’s 100% Hydrogen DLE Gas Turbine Combustion Technology Platform Development. This includes a summary of the results of the world’s first gas turbine engine tests across the entire range of  H₂/natural gas blends with focus on combustion performance. The SGT-400 Engine testing has been conducted on natural gas at the Siemens Energy factory in Lincoln (UK) and with various levels of hydrogen up to 100% at the customer site in Saillat-Sur-Vienne (France). An engine safe operation envelope with respect to flashback will be presented and engine data will be compared against rig test data obtained at Clean Energy Center in Ludwigsfelde (Germany) at relevant engine conditions. The embrittling effect of gaseous hydrogen on the material of the gas-bearing components is another relevant aspect. To evaluate the influence of embrittlement on component lifetime, Siemens Energy is working on the development of test methods under hydrogen conditions. In addition to generating reliable hydrogen affected material design data for the SE portfolio materials, this paper will also present the performance of welded and brazed joints under the influence of hydrogen.

Finally, the paper will provide an outlook on the scaling of the demonstrated hydrogen technology to Siemens Energy’s gas turbine portfolio.
