What are Cryogenic fuels?

  • Cryogenic means low temperature.
  • They are fuels that requires extremely low storage temperature.
  • Thus, the space environment cannot support combustion. And therefore, highly low temperature fuels are needed.
  • Usually the cryogenic engines use liquid hydrogen as fuel and liquid oxygen as oxidiser.
  • This is because oxygen can be kept in liquid state that is below -183 degrees Celsius.
  • On the other hand, the liquid hydrogen is kept at -253 degree Celsius.
