Cofiring 45% hydrogen in F-class gasturbine: Looking beyond the GT

Today, gas fired assets are an ideal companion for our renewable assets, being dispatched in a flexible way to ensure the grid stability. The EU came with taxonomy categorising power plants based on their CO2 emissions, and thus their risk of harming reaching the Paris agreement goals. Within the ENGIE fleet, the GT26 units could achieve, with the latest engine upgrades and hydrogen cofiring, the threshold value of 270 g CO2/kWh, where these are considered not doing any harm to reach the goals. Based on an existing power plant configuration, ENGIE has conducted a feasibility study to explore the technical possibilities and on-site modifications to reach 45 vol% hydrogen cofiring on the GT26 gas turbine. Several challenges were identified, such as the risk of flashback, higher NOX emissions, and fuel gas compressor selection for the hydrogen preparation.
