Our Design and Development Teams
From idea, to prototype, to testing and ultimately serial production: Our design and development teams turn a vision into well a thought-out solution. With passion, motivation and strategic focus. Close exchange with the production on-site is especially important. At the Quest One sites for electrolysers (Augsburg site) and electrolysis stacks (Braak site), we evaluate each concept for industrial producibility at a very early stage. This strengthens our teamwork and makes our products even better.
Our Production Teams
Two production sites, one common goal: Build the best PEM stacks and electrolyzers. This is technically very demanding. Our production teams are correspondingly highly specialized and feature a cross-departmental network. For the production at the Quest One sites in Augsburg (Bavaria) and Braak near Hamburg, we create innovative technologies for green hydrogen production based on many years of experience and highly specialized know-how. This begins with the development of the components. This is followed by the assembly process and factory acceptance of the systems on the test bench, and finally the logistics. Quality from the first component to the last detail.
Our Service Teams
To ensure that your hydrogen production with Quest One starts smoothly and runs continuously, the Project Execution & Customer Services department assumes responsibility for further strategic, organizational, administrative and technical support immediately after the contract is signed. In addition to 24/7 remote monitoring via our Technical Service Center, the well-trained service teams personally take care of the on-site maintenance work. They check, test and clean. Replace wear parts, order spare parts and install them professionally. Everything in close cooperation with the development and production teams. Always efficient and reliable. This cooperation not only creates technical synergies but also human ones.
