Hydrogen Technologies

Developments in hydrogen technology focus on applications in power engineering and transport. Our ecological TriHyBus and hydrogen fueling stations have been verified by the traffic in the town of Neratovice. The implementation of the energy surplus storage system from photovoltaic panels to hydrogen in Řež has demonstrated the efficiency of heat and power generation from hydrogen.

Our Services and Projects

  • Turn-key implementation of systems
  • Processing a case study integrating hydrogen technology into your facility or operation
    • Individual selection of suitable technology according to client requirements and input parameters
  • Energy storage systems that can serve as back-up power sources or to stabilize the power supplied to the grid from renewable sources
  • Energy storage systems that help create energy self-efficient facilities/ buildings
  • For the energy storage system we provide the following:
    • Advice
    • Designing a suitable system
    • Economic expertise of the system
    • Design activities
    • Implementation of the system
    • Drafting a proposal to co-finance the project from subsidy titles

The system of storing surplus energy from photovoltaic panels into hydrogen in the ÚJV Řež area consists of a photovoltaic power plant, PEM (hydrogen - electricity), a compressed hydrogen storage tank, a PEM fuel cell (hydrogen - electricity) and a connection to the distribution network.

Scheme of interconnection of photovoltaic panels and hydrogen storage system:


  • For small, medium and large businesses that need a backup power supply;
    • Suitable for applications without access to electricity and natural gas;
  • For all who want to run buildings, island-mode businesses (independent of the power grid);
  • For all who want to use and stabilize renewable energy more efficiently;
  • For all who need an ecological source of high purity hydrogen;
  • For all who want to produce heat and electricity based on micro/cogeneration units with high efficiency (suitable for households, residential buildings or commercial buildings and businesses).

Benefits of the system or individual components:

  • Flexible and efficient heat and power generation from hydrogen / natural gas based on micro-cogeneration / cogeneration units;
  • Low-emission equipment leads to the local improvement of air quality (reduction of emissions, dust, and noise);
  • Reducing the cost of the primary energy source;
  • Long-term storage of energy;
  • Backup system in the event of a power failure;
  • In the case of an “island system”, it is independent of the distribution grid;
  • The possibility to co-finance the project from public sources



  • Advice on integrating hydrogen cars and fleet buses
  • Support of the development of petrol station infrastructure in the Czech Republic
  • In the field of utilization of hydrogen technologies in transport, we provide:
    • Advisory activity
    • Designing a suitable system
    • The economic side of the system
    • Turnkey implementation
    • Drafting a proposal to co-finance the project from subsidy titles

City bus with triple hybrid electric drive and hydrogen fuel cells + hydrogen fueling station in Neratovice

  • Awarded the Gold Medal at the International Engineering Fair in Brno
  • The bus has been successfully operated on the Neratovice city line for 5 years
  • Continuation of the project is planned with an emphasis on sustainable local hydrogen production in relation to renewable energy sources. This means strengthening the overall non-emissive aspect of bus traffic.


  • 12-metre two-axle bus
  • Electric motor 120kW
  • Fuel cell 48kW
  • AccumulatorsLi-ion 28kWh
  • Max speed 65km/h (reduced)
  • Distance up to 300km
  • Max peak performance 200kW


  • High efficiency of operation
    • The vehicle fuel cell is used as an energy source for an electric motor that can handle energy much better than an internal combustion engine, a fuel cell drive is significantly more energy efficient than a diesel engine or compressed natural gas
  • Ecology
    • In addition to greenhouse gas emissions, fuel-cell drives or fuel-cell power units save heat generators from other harmful emissions that arise regardless of the type of propulsion. These include, in particular, solid particles or nitrogen oxides which arise, for example, in the burning of “green” fuel, such as natural gas.
