Underlying
Technology

  • Gas Turbines: Hydrogen can be used as a fuel in modified gas turbines, similar to natural gas. The hydrogen is combusted with air, and the resulting hot gases expand through a turbine, generating mechanical energy that is converted into electricity by a generator.
  • Fuel Cells: Fuel cells use an electrochemical process to convert the chemical energy of hydrogen directly into electricity, with high efficiency and low emissions.
  • Internal Combustion Engines: Hydrogen can also be used as a fuel in internal combustion engines, although this technology is less common for power generation applications.
