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. And to avoid 1% of the global CO2 emissions by our electrolyzers.

We are a technology leader with a strong core
With more than 25 years of experience in PEM electrolysis, we have a strong technological core and expertise in the field of green hydrogen production. Secured funding of 500 million euros in 2022 has enabled the industrialization and serial production of our technology.
We realize series production
In order to realize the production of our PEM stacks and electrolyzers in series, we are building a state-of-the-art and climate-neutral production and development site for PEM electrolyzer stacks in Hamburg. Construction of the automated factory is part of the PEP.IN research project and is funded by the Federal Ministry of Education and Research (BMBF) via the H₂Giga lead project for hydrogen generation.

We rely on the competence of our parent company
Around the world people place their trust in the know-how of heavy industry. And we too draw on the expertise of MAN Energy Solutions in the areas of plant EPC, industrial compressors and reactors. Projects designed for the generation of green hydrogen benefit from the many years of experience in the implementation of large-scale projects along with the global sales and customer service network.
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.

On April 26, 2023, the official groundbreaking ceremony of the new H-TEC Stack Manufacturing & Development Center took place at Victoria Park Hamburg.
This new site will be a state-of-the-art center for research, development, production and testing of innovative PEM electrolysis stacks, the core technology
for green hydrogen production. In the future, PEM stacks with an annual production capacity of five gigawatts, will be manufactured automatically and in series.
- Planned completion: 2024
- 11,000 m² for production and testing
- Stack development, manufacturing, testing and service
