SG Hydrogen is the first Czech commercial electrolyser project for producing green hydrogen using electricity from a rooftop solar power plant at the headquarters of the company Solar Global. The headquarters are located in close proximity to a motorway network near Napajedla (Zlín region), and therefore offer ideal facilities and conditions for distributing products, components and complete systems for the power engineering industry. Our Group is a pioneer of solar energy development in the Czech Republic, so it makes sense that we are among the first to enter the hydrogen economy. We believe that it is precisely green hydrogen produced using energy from renewable sources that will make it possible to decarbonise power engineering, industry and mobility.
Hydrogen production will be ensured by a PEM electrolyser from the German company H-TEC SYSTEMS with a nominal power of 225 kW and a production capacity of 100 kg of hydrogen per day. That is a quantity roughly corresponding to 10,000 km of travel in a passenger car (on the Czech market, for example, a Toyota Mirai or Hyudai Nexo), or about 1,000 km of travel by a hydrogen bus. We will obtain the required energy from our rooftop photovoltaic power plant with an output of 600 kWp. The wide power range of the electrolyser and its rapid power response will allow us to adapt as much as possible to the variable production of electricity from renewable sources.
Our product will be highly pure hydrogen that meets the requirements of automotive fuel cells. This high-purity hydrogen can be used in automotive transport, for example, whether for passenger cars, buses or lorries, while it can also be found as an integral part of certain industrial processes.
An inseparable part of the electrolyser is a hydrogen storage system with its own compressor unit. The storage system will be able to hold around 500 kg of compressed hydrogen gas. For comparison with our high-capacity megawatt-hour battery storage, this means an energy capacity of about 16 MWh (LHV).
Despite the generally poor reputation of hydrogen storage, the hydrogen storage system is much more efficient than the current high-capacity battery energy storage system (BESS) in terms of price per unit of stored energy.

Frequently asked questions.
“The carbon age is slowly coming to an end. This challenge presents interesting opportunities for Czech technology companies that could prove successful on European markets with modern energy solutions. Our technological centre gives the Zlín region the interesting outlook of a new field that combines the development of renewable sources and energy storage. We will create jobs with added value where people will be able to contribute to the modernisation of the energy sector in the Czech Republic and beyond.”Ing. Vítězslav SkopalCEO
How do you take your coffee? Our filling station can fill your car’s tank within 5 minutes. It takes about triple that time to fill the tank of a bus.
At a maximum production rate of 100 kg of hydrogen per day, we can fill 15 cars with enough fuel to cover 650 km. Together, we can travel a massive 10,000 km with the fuel we produce in one day.
Our premises will include a public filling station for road traffic. It will provide fuel for cars, lorries and buses.
Thanks to a higher energy density and a shorter refuelling time, hydrogen in combination with fuel cells is a favourable choice for long-distance transport and heavy loads.
By 2050, hydrogen is expected to account for up to 24% of the global energy demand. The technology will not replace other ecological alternatives, but will suitably supplement them when traditional batteries will not do.
Since green hydrogen has the smallest carbon dioxide footprint, it is a step in the right direction for a better emission-free future. Green hydrogen production is a great solution for exploiting the ever-increasing surplus of renewable energy.
