Future Energy Systems without Baseload Power: German Research Findings
Key Ideas
  • German research academies state that a secure energy supply can be achieved without baseload power plants through a mix of solar, wind, storage, hydrogen, and flexible electricity demand.
  • The German government plans to incorporate hydrogen-fuelled gas turbine plants to support its renewable energy-based electricity system.
  • Researchers evaluated the potential of baseload technologies like nuclear power, geothermal energy, and gas plants with CO2 capture, suggesting that baseload plants could be viable if costs significantly decrease.
  • Baseload plants could play a key role in producing surplus electricity to operate electrolysers for converting electricity into hydrogen, contributing to a more sustainable energy system.
German research academies, including acatech, Leopoldina, and the Union of the German Academies of Sciences and Humanities, have shared findings from the 'Energy Systems of the Future' project. They concluded that a reliable energy supply can be achieved without the need for baseload power plants. By combining solar and wind energy with storage, a flexible hydrogen system, and residual load power plants, a climate-friendly and secure electricity supply can be ensured. The German government's strategy includes using hydrogen-fuelled gas turbine plants to support their renewable energy-focused electricity system. The researchers assessed the potential of baseload technologies like nuclear power, geothermal energy, and gas plants with CO2 capture, highlighting the possibility of baseload plants being a part of future energy systems if costs decrease significantly. Karen Pittel, from the ifo Institute, emphasized the importance of cost efficiency in baseload technologies, stating that the risks of cost increases and delays are higher than with the expansion of solar and wind energy. The surplus electricity from baseload plants could be utilized to run electrolysers, which convert electricity into hydrogen, further enhancing the sustainability of the energy system.
