Quest One employs around 550 people at three locations: production and development of the electrolysis stacks are based in Hamburg, Germany, while the electrolyzers are produced at a site in Augsburg, Germany. The company has another location in the U.S. near Houston, Texas.

Quest One is the way forward

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

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 includes funding by the German Federal Ministry of Education and Research (BMBF) via the H2Giga lead project for hydrogen generation.

We benefit from 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 many years of experience in the implementation of large-scale projects, along with the global sales and customer service network.

Our environmental guidelines

Quest One 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.
Quest One 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 Quest One 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, to avoid waste and reduce emissions.
