Hydrogen Energy

Hydrogen Energy and Fuel Cells:
Part of a Sustainable Energy Future
What is hydrogen?
  * Hydrogen is a chemical element colorless, odourless
  * A gas at room temperature. It reacts with oxygen, generating both water and energy.
  *   Hydrogen can be used as a fuel in combustion engines or to generate electricity in novel fuel cells
  * As similar to natural gas, with two important differences; hydrogen cannot simply be mined like methane; and when hydrogen is burned(reacted with oxygen) it does not produce carbon dioxide.
  * Reduction of CO2 emissions, helping to mitigate climate change
  *   Reduction of energy imports
  *   Diversification of energy supplies, reducing dependence on fuels such as oil
  *   Improved local air quality
  *   Assistance in the introduction of new fuel cell technologies which offer high efficiencies
Hydrogen Energy Economy
  * Reducing CO2 emissions and improving security of energy supply are the two main drivers for hydrogen fuel.
  *   An important advantage of hydrogen is that it can be produced from a range of primary energy sources, either fossil fuels or renewable.
  *   Hydrogen can be used to generate electricity using fuel cells, or motion
  * using the simpler but less efficient internal combustion engine.
  * While hydrogen could be used as a fuel in a wide range of applications, it is in the transport sector where its benefits are most clear.
  *   Other than hydrogen, there are two main alternatives to fossil oil in vehicles
– biofuel powered vehicles and battery electric vehicles.
  *   Each has its associated difficulties.
  *   As well as in vehicles, fuel cells have a number of stationary energy applications, from portable electronics to large scale electricity generation.
  * Hydrogen energy technology – production, storage, transport and end-use –
is at the pre-commercialization stage, and significant technical and financial challenges remain.
  *   One of the main technical...
