Transcript of "Hydrogen from aluminium for vehicle propulsion"

  1. 1. Aluminium as a Fuel Aluminium Eamon Keane Co-Authors: Dr David Browne & Dr Alun Carr University College Dublin
  2. 2. Water + Aluminium-Gallium Fuel Pellets
  3. 3. Prof. Jerry Woodall, Purdue University Claims: <ul><li>Energy efficient – 50% recycling efficiency </li></ul><ul><li>Environmentally sound </li></ul><ul><li>Cheap – equivalent to $3/gallon for petrol </li></ul><ul><li>Scalable (enough gallium for 1 billion cars) </li></ul><ul><li>Reaction is: </li></ul><ul><li>Gallium is inert in the reaction </li></ul><ul><li>Can use variable wind power for electrolysis </li></ul>
