Germany's decarbonisation hinges on €324B hydrogen-ready gas plant push by 2050
A new study suggests Germany can fully decarbonise its energy system—but only with major investment in hydrogen-ready gas plants. Researchers from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) warn that without flexible capacity, costs and security risks will rise. Their findings highlight a gap between current plans and what's actually needed by 2050. The FAU study identifies hydrogen-capable gas plants as key to cutting emissions while keeping energy affordable. These facilities can initially burn natural gas before switching entirely to hydrogen. One such plant, EnBW's gas turbine in Stuttgart-Münster, is already prepared for hydrogen use.
According to the research, at least 53 gigawatts (GW) of hydrogen-ready capacity will be required. The German government's current strategy, however, targets just 12 GW. The authors estimate total system transformation costs through 2050 will reach at least €324 billion. A higher carbon price would speed up the shift away from fossil fuels. This would push investment into hydrogen plants, lowering both emissions and overall system costs. The study also notes that hydrogen-ready plants improve flexibility, reducing reliance on extra battery storage and new wind or solar farms. As a result, less wind power would need to be wasted through curtailment.
The report makes clear that Germany's energy transition depends on scaling up hydrogen-ready infrastructure. Without the full 53 GW of capacity, the country risks higher costs and potential energy shortages. The findings urge policymakers to align their targets more closely with the study's recommendations.
