Quest One and MAN Energy Solutions building large-scale electrolyzer demo plant

Quest One has started construction of a demonstration plant for its Modular Hydrogen Platform (MHP) PEM electrolyzer in Augsburg, Germany.

The electrolyzer will be installed in a test stand at the Turbocharger Performance Center located on the Augsburg site of MAN Energy Solutions, where it will generate data in test operation for continuous optimization.

With the demonstration plant, Quest One is turning large electrolyzers into a tangible experience. Operational constraints often mean that these plants cannot be viewed while they are in use at customers’ sites. The joint project aims to change this: from mid-2025, potential customers, project developers, and EPCs will be able to visit the demonstration plant. This will give them valuable insights into the construction phases, dimensions, inner workings, and infrastructure.

Construction began at the end of 2024 with the installation of freshwater treatment equipment. The plant will be assembled over the course of 2025, so test operations can start by early 2026. Potential business partners will already be able to gain insights into the construction phase and visit the plant onsite in Augsburg in 2025.

A second objective of the joint project with MAN Energy Solutions is to continuously optimize the scale of PEM electrolyzers based on field data and to further refine both system operations and the installation and service concept.
