  1. Hydrogen: energy of the future? RémiOlivari, Anna Szucs, Baudouin de Marsac, José Carlos Curiel Franco

  2. Content • Basics of Hydrogen • Source and Production • Use • Pros and contras • Conclusion

  3. Basics of Hydrogen

  4. INTRODUCTION I The chemical element with atomic number 1 The lightest and most abundant chemical element Hydrogen exists as Dihydrogen H2 Colorless, odorless, and highly combustible.

  5. INTRODUCTION II • It was discovered by Henry Cavendish in the 18 Century • H2 has several important uses in industry: • Production of ammonia. • Processing ("upgrading") of fossil fuels • Production of methanol. Now, applications can be found in the chemical, power generation, aerospace, telecommunications industries, automotive…

  6. Source and Production

  7. Source and production • Unavailable on earth in the H2 form • From Water • Electrolysis • From hydrocarbon • By the oil industry • Other source

  8. Electrolysis • The electrical current “breaks” the molecule • Simple and generates pure H2 • Several methods • 5% of the production

  9. From Hydrocarbon • Use of the H component of the hydrocarbon • Several source • Coal • Oil • Several Method • Steam reforming reactions • Partial oxidation

  10. Steam reforming reactions

  11. Usage and applications

  12. Application • Huge need in petroleum and chemical industry • Ammonia production • Hydrogenating agent • Rocket propulsion • Mixture of liquid H2 and Oxygen • Fuel cell • Vehicles • Independent energy producing unit (field hospital, cell phone relay)

  13. Application • Examples In physics and engineering • Rotor coolant in electrical generators at power stations • Welding process (atomic hydrogen welding) • Semi-conductor , automotive, chemical, power generation, aerospace etc. industries

  14. Pros and contras

  15. Advantages • Hydrogen: • Abundance & Convertibility • Clean • Can be produced by electrolyze • High mass energy 120MJ/kg • FuelCell: • High efficiency • No noise nor vibration • No pollution

  16. Drawbacks • Hydrogen: • Highly flammable 4% & explosive 13% in air • Large flammable span 4 to 73% • Small volumetric power • Isolation problems • FuelCell: • Cost • Lifespan • Fabrication • Fuel availability

  17. Conclusion • Many industrial applications • Can be produced through different process • H2 is environmentally friendly and a renewable source of energy
