Our core values

As a provider of specific and individual comprehensive solutions, we put our customers and partners at the centre. The strong focus on partnerships and networks - also with competitors - requires an inclusive approach that opens doors and unlocks shared potential. We see ourselves as a fast and innovative as well as a solution-oriented and passionate "H2 team": a special unit of experts that finds the best possible solution for numerous "hydrogen challenges" of its customers.

The enthusiasm and unconditional commitment to this solution competence is the basis of all internal and external communication, which in turn finds its roots in our values.

Corporate Mission

We are a leading supplier and developer of core components for hydrogen technologies. With more than 200 (as of 11/23) highly specialised employees at its headquarters in Nordhausen (Germany) and its branch offices in the USA and France, we combine the know-how of approx. 700 patents from the hydrogen sector.


As part of the Schmidt Kranz Group, founded in 1885, Maximator Hydrogen GmbH offers comprehensive system solutions for the entire value chain of hydrogen technologies: from the development of specialised components, to the production, transport and distribution of hydrogen, to customer support for end users.


As a fast and efficient partner for the planning, construction and operation of hydrogen infrastructures for road, rail and marine transport, Maximator Hydrogen GmbH offers its customers highly reliable and modern hydrogen filling stations including service and support. To this end, the company maintains strong networks with filling station operators and energy companies such as Avia. In addition, the company is currently building Germany's largest production facility for hydrogen filling stations at its headquarters in Nordhausen. Maximator Hydrogen GmbH's special hydrogen competence is based on its many years of expertise in the development and production of compression technologies for gaseous and liquid energy carriers and fuels. Together with the technological development team at Maximator MAT in Vienna, Maximator Hydrogen GmbH continues to develop this key technology in a consistent and focused manner for hydrogen operation. Through comprehensive networking within the various divisions of the Schmidt Kranz Group, Maximator Hydrogen GmbH translates this expertise into specialised and highly demand-oriented total solutions for hydrogen-based transport infrastructures. As a system solution provider, Maximator Hydrogen GmbH is thus the spearhead of the Schmidt Kranz Group for fast, individual and sustainable hydrogen applications.


In order to live up to this claim, Maximator Hydrogen GmbH relies on a highly specialised workforce with many years of expertise in the development, exploitation and provision of hydrogen technologies. The Maximator Hydrogen GmbH team combines the know-how of around 700 hydrogen-related patents in which they have been involved in the course of their individual careers - an expertise and innovative strength in the hydrogen sector that is unparalleled anywhere in the world.


In addition to technical expertise and solution- and customer-oriented planning, development and implementation processes, the greatest possible openness to partnerships is a central component of the company's philosophy. With its high performance, flexibility and speed, Maximator Hydrogen GmbH is a valuable partner for specifically tailored solutions in projects of large international companies and corporations.

OHSAS | Health, occupational safety and environmental policy

Health, occupational safety and environmental policy of Maximator Hydrogen GmbH

Sustainable corporate management requires modern companies such as our to integrate social interests and environmental protection concerns into their business activities. As a global supplier of hydrogen refuelling systems, one of our core tasks is to actively shape the framework conditions for this. For this reason, we have declared a sustainable corporate policy based on occupational safety and environmental protection to be an essential part of our value system.


Our commitment goes beyond the legal obligations. Our business activities are not only regulated by international occupational safety and environmental protection principles. We implement the comparatively strict occupational safety and environmental standards of the Federal Republic of Germany and exceed the minimum standards prevailing in many other countries around the world. In the area of occupational safety we strive to establish the requirements of ISO 45001 and in the area of environmental management the requirements of ISO 14001 in our company.


Occupational safety: taking responsibility

Our company's success depends first and foremost on efficient employees, for whose safety and health we bear responsibility. To this end, we have anchored far-reaching standards for occupational health and safety in both the corporate code of conduct and the corporate mission statement. We are convinced that accidents and injuries are preventable. The interaction of intelligent technical safety equipment, targeted training and the active cooperation of all are the basis for this. Based on these measures, we place a high priority on the safety and well-being of our employees and demonstrate responsibility not only to them, but also to our subcontractors, customers and all members of the public who are affected by our activities.


The management of Maximator Hydrogen GmbH does everything in its power to create the framework conditions for effective occupational health and safety. In the committees for occupational safety, measures to avert and avoid hazards are regularly defined, documented and their implementation monitored. In addition, we implement workplace health promotion and define measures to promote health awareness among employees and to positively influence their health behaviour. The personal commitment of our employees is essential. They are also responsible for implementing the guidelines for occupational safety and health protection.


Minimum Wage

We undertake to comply with the provisions of the Minimum Wage Act, including paying the statutory minimum wage to our employees.


Furthermore, we undertake to oblige subcontractors or contracted hire companies to pay the statutory minimum wage to their employees.


Our history

A large portion of know-how, human dexterity and skills leading to unique ideas and courageous decisions put our vision on an unshakable pedestal. Once Jules Verne spoke of the future energy supply of the earth through hydrogen. Today, we speak of the center for hydrogen technology and climate-neutral infrastructures, manufactured in the green center of Germany.
