A Hydrogen-Fueled Micro Gas Turbine Unit for Carbon-Free Heat and Power Generation

The energy transition with transformation into predominantly renewable sources requires technology development to secure power production at all times, despite the intermittent nature of renewables. Micro gas turbines (MGTs) are small heat and generation units fast startup load-following capability thereby suitable backup for future’s decentralized systems. Due MGTs’ fuel flexibility, a range fuels from high-heat low-heat content could be utilized, different greenhouse generation. Developing micro that can operate carbon-free will guarantee zero CO2 emission contribute alleviation global warming problem. In this paper, redevelopment standard 100-kW turbine run methane/hydrogen blended is presented. Enabling hydrogen has been pursued by researchers decades. first running pure was developed in Stavanger, Norway, launched May 2022. This achieved through collaboration between University Stavanger (UiS) German Aerospace Centre (DLR). paper provides an overview project reports experimental results engine operating fuel, various up 100%. During process, MGT’s original combustor replaced innovative design deal challenges burning hydrogen. train mixing unit, new valves, additional controller enables required input maintain maximum output, independent blend specification. presents test rig setup preliminary campaign, which verifies MGT unit support minimum production. Results provided paper. varied 50% 100% (volume-based) outputs 35kW 100kW were tested. modifications engine, mainly combustor, train, valve settings, controller, resulted stable operation NOx emissions below allowed limits. Running full load less than 25 ppm emissions, carbon-based
