Green hydrogen: H-TEC SYSTEMS applications

Green hydrogen is our element

Producing green hydrogen from renewable energy

Producing green hydrogen from renewable energy

Pure water, renewable energy, and H-TEC SYSTEMS: That's all it takes to produce green hydrogen. To meet these challenges, we have been continuously optimizing PEM electrolysis and increasing the productivity of our plants. The result is a technological advancement that will enable the decarbonization of a wide range of industries - not in the future, but today.

Hydrogen production and storage on-site is a decisive step toward energy self-sufficiency. When produced with 100 % renewable electricity, green hydrogen makes an important contribution to reducing CO2 emissions. Germany's aim is to reduce emissions by 55% by 2030 and 95% by 2050. This goal cannot be achieved with "blue" or "gray" hydrogen, which are produced using fossil fuels.

The PEM electrolysis technology from H-TEC SYSTEMS is specifically designed for the production of green hydrogen, and hence enables sector integration. Energy systems such as electricity and heat can be integrated just as effortlessly as mobility. This creates synergy. And plenty of new opportunities.

Green hydrogen – applications

CO₂ neutral mobility

CO₂ neutral mobility

Mobility leaves a footprint - at least up to now. Hydrogen from our PEM electrolysis can be used directly for fuel cells and is therefore emission-free and climate-friendly. That makes traffic cleaner and quieter. Power-to-X processes make it possible to generate fuels for aircraft or ships.

Raw material for industrial goods

Raw material for industrial goods

Mixing carbon dioxide (CO2) and hydrogen (H2) produces a high-quality syngas. This is a pioneering process for capturing CO2 emissions and using them to produce the chemical building blocks for chemicals, polymers or synthetic fuels. Even the production of ammonia (NH3), the main ingredient for mineral fertilizers, is possible with climate-friendly green hydrogen.

Decarbonization of industrial processes

Decarbonization of industrial processes

The production and processing of raw materials and goods requires large amounts of energy. Hydrogen can improve the CO2 balance of these processes, e.g. heating of kilns in glass, cement or steel production. Feeding hydrogen into the natural gas network at rates of up to 10 % and more is possible and provides a long-term energy storage solution.

Energy storage for balancing the power grid

Energy storage for balancing the power grid

Surplus electricity is converted into green hydrogen via electrolysis with water. This can be stored conveniently and over a long period of time in the natural gas grid or in tanks, and accessed again when renewables aren’t available.

Decarbonization of domestic energy systems

Electrolysis produces not only hydrogen, but also 65 °C heat as a by-product. This is valuable energy that can be fed into the district heating network or used directly to heat residential and commercial premises. Fuel cell heating systems also benefit from the principle of cogeneration.

PEM electrolysis

The advantages of PEM electrolysis 
at a glance

PEM stands for "Proton Exchange Membrane", which in turn stands for a whole host of advantages:

  • PEM electrolysis is the preferred technology for green hydrogen production, through the splitting of water by electricity
  • Can be operated at dynamic partial load, i.e. compensating for the load fluctuations of renewable energy
  • PEM produces high-purity hydrogen that can be used directly for refuelling
  •  Does not require aggressive chemicals and does not use a liquid electrolyte
  • Tried and tested technology, now ready for use on an industrial scale with H-TEC SYSTEMS
