Specifications Events & Fairs

Hydrogen-based power supply for
mobile and semi-stationary applications

The H₂Genset is a flexible and mobile generator using hydrogen for use in areas without access to the conventional power grid, e.g. on construction sites, at outdoor events, for the temporary power supply of telecommunication masts or as a mobile emergency power supply in the event of catastrophes. Optionally, it can also be configured for use as a mobile emergency power generator without the need for foundations or planning permission.

With a peak output of 20 kW, the H₂Genset can be used in many applications such as:

  • Structural & civil engineering
  • Emergency power supply for critical infrastructures (CI)
  • Road construction and maintenance
  • Emergency services
  • Technical relief organizations
  • Events and film industry
  • Forestry industry
  • Military

H₂Genset in use

Emission-free hydrogen fuel cell technology

The EFOY hydrogen fuel cell modules integrated in the H₂Genset are based on proven PEM (polymer electrolyte membrane) technology. The fuel cells produce electricity from hydrogen, supplemented by oxygen from the air. They convert hydrogen directly into electricity and the only waste product produced is water vapor. This is exceptionally environmentally friendly.

Modular design with
integrated tank system

Thanks to the modular design with integrated EFOY hydrogen fuel cells, the performance range can be precisely tailored to suit your requirements. The H₂Genset has an integrated hydrogen tank system and uses proven fuel cell technology to provide energy cleanly and quietly. It also needs little maintenance and is cheap to run.


Hydrogen refuel

The H₂Genset can be refueled quickly and easily at H₂ filling stations. For even greater self-sufficiency, the H₂Genset also has a connection for an external tank, e.g. a standard 12-cylinder gas cylinder bundle.

Flexible and emission-free

Hydrogen fuel cells are a climate-neutral, quiet and highly efficient alternative option for covering increased electricity demands and guaranteeing a (back-up) power supply without the need for diesel-powered solutions. The H₂Genset’s uses are not limited to its standard role as a reliable emergency power generator. It can also secure the power supply in areas without access to the conventional power grid. The H₂ generator is an advanced, climate-neutral, and incredibly flexible power supply system.

Remote monitoring via cloud platform

Monitor individual generators or entire fleets conveniently and easily using a suitable IoT solution. The H₂Genset has an integrated cloud connection and can therefore be monitored using the associated web app. Your dashboard shows device data, such as the fill level or the location displayed on a map. The cloud platform also provides extensive functions, such as usage analyses, early fault detection, automated cost calculations for rental equipment, and the integration of geofences into fleet management systems.
