Dihydrogen Fuel


  • Dihydrogen releases large amounts of heat on combustion and can release more energy than petrol on a mass-for-mass basis.
  • Combustion of dihydrogen produces less pollutants than petrol, with the only pollutants being the oxides of dinitrogen due to the presence of dinitrogen as an impurity.
  • Dihydrogen gas is stored in metal alloy tanks, but these tanks can be heavy and require expensive insulated tanks.
  • The hydrogen economy involves the transportation and storage of energy in the form of liquid or gaseous dihydrogen.
  • Dihydrogen is used in fuel cells for the generation of electric power.
  • A pilot project using dihydrogen as fuel for automobiles was launched in India in 2005, where 5% dihydrogen was mixed with CNG and gradually increased to reach the optimum level.
