High purity graphite is used in Graphite Energy’s technology as it possesses a unique combination of properties that make it ideal for thermal energy storage including:

  • Chemically and mechanically stable at extremely high temperatures (> 2,000°C)
  • High specific heat at high temperature
  • Thermal conductivity specified to match the design heat extraction rate
  • Low co-efficient of thermal expansion
  • Highly resistant to thermal shock
