Hydrogen is widely recognised as a potentially environmentally friendly energy carrier which could mitigate greenhouse gas emissions from the transport sector, if supplied properly.

Fuel cells are widely acknowledged to be the technology of choice for turning hydrogen into energy (although combustion engines are another option). Highly efficient, these intrinsically clean energy converters are adaptable to a wide range of energy-consuming applications, including small portable devices, small and large combined heat and power, as well as road, rail, sea and air transport applications. Fuel-flexible fuel-cell systems, as they do not rely on a dedicated hydrogen distribution infrastructure, could enable a convenient transition to a longer term “hydrogen economy”.

Technology Challenges

The field of hydrogen & fuel cell technology can be broken down into five areas:

  • - hydrogen production;
  • - hydrogen storage and distribution;
  • - stationary applications (fuel cells transition);
  • - transport applications;
  • - portable applications.
