H-TEC SYSTEMS enables CO₂ neutrality with hydrogen technology

H-TEC SYSTEMS enables CO₂ neutrality with hydrogen technology

H-TEC SYSTEMS is a hydrogen expert, innovation driver and partner in the energy transition. For our future and for our customers we develop innovative PEM electrolyzers and electrolysis stacks for green hydrogen production. As a technological pioneer, we have been playing a decisive role in shaping hydrogen technology for over 25 years. - At two locations in Germany and across all sectors.

We believe that mobility, production, and consumption are possible without emissions. With consideration for future generations and respect for nature. Not someday, with our technology already today. How every country, every industry and every company can achieve this goal? With our know-how, our service and our products. To achieve this, H-TEC SYSTEMS builds on cooperation with visionary customers and partners, and the power of our parent company MAN Energy Solutions. Together, we are making hydrogen production green and the CO2-neutral transformation of all sectors a reality.
That's why our goal is to convert renewable energies into green hydrogen by using leading PEM electrolysis technology. And thus fuel a new, emission-free energy era. This is what we stand for.

The future speaks for H-TEC SYSTEMS

Our environmental guideline

Our environmental guideline

  • H-TEC SYSTEMS GmbH develops and produces hydrogen electrolyzers. With our products, hydrogen will become the most important energy carrier worldwide and the foundation for a sustainable energy system.
  • H-TEC SYSTEMS has set itself the goal of sustainable value creation and is aware of its own special responsibility for the environment.
  • As a commercial enterprise, we bear responsibility for the environmental impact and sustainability of our products, sites, and services. We rely on environmentally compatible, advanced, and efficient technologies and implement them throughout the entire life cycle of our products. As early as the development and production stages, we consider the careful use of natural resources, a continuous reduction of environmental impact, and compliance with environmental protection laws and regulations. In addition, we constantly reassess the environmental compatibility of products and manufacturing processes and optimize them when necessary.

We live environmental protection and sustainability not only through our products, but also in our everyday work. The Augsburg site of H-TEC SYSTEMS has been awarded the Ökoprofit certificate, an environmental management program that guarantees a high standard of operational environmental protection through defined criteria. 

We take technical and organizational measures to save raw materials, water and energy, avoid waste and reduce emissions.
