Thermal Energy Storage

  • Thermal energy storage (TES) systems have the potential to satisfy the increasing demand for flexibility at particularly low costs, compared to e.g. electrical batteries. At KIT the focus is placed on high-temperature TES using liquid metals as advanced heat transport fluids.
  • Liquid metals offer the advantages of high transport efficiency, fast dynamic response and operation at high temperatures well beyond 700°C for TES integration in energy-intensive industries, innovative high-temperature chemical processes and CSP. Liquid-metal-based TES systems at high-temperature levels and high efficiency have the potential to be a game changer in numerous applications that are based on fossil-fuel heat supply today.
  • KIT covers the complete research area from materials development over thermal hydraulics to component design and laboratory testing.
