Today there is limited operational experience on co-combustion of hydrogen and natural gas in an existing gas turbine in an industrial environment. The ENGIE owned Siemens SGT-600 (Alstom legacy GT10B) 24 MW industrial gas turbine in the port of Antwerp (Belgium) was selected as a demonstrator for co-firing natural gas with hydrogen as it enables ENGIE to perform tests at higher H2 contents (up to 25 vol%) on a representative turbine with limited hydrogen volume flow (1 truck load at a time). Several challenges like increasing risk of flame flashback due to the enhanced turbulent flame speed, avoiding higher NOx emissions due to an increase of local flame temperature, supply and homogeneous mixi...
