Hydrogen Technology World Expo

Trade fair / October 21, 2025 - October 23, 2025

Hydrogen Technology World Expo

Hydrogen and its derivatives are an important pillar in a sustainable global energy trading system, since they store vast amounts of energy over long periods of time, are transported in ships or pipelines, and will be used in all energy-consuming sectors as a replacement of fossil-based energy carriers. Furthermore, hydrogen is the basic molecule used in generating renewable synthetic fuels or chemicals.

For over 30 years, we have been supporting the development of climate-neutral industrial processes and sustainable mobility with the development of hydrogen technologies.

Join us at the Hydrogen Technology World Expo to:

Explore our technology and service portfolio. We will present innovative solutions and product developments in the fields of Production of Fuel Cell and Electrolysis Membrane Electrode Assemblies, CO2 Direct Air Capture, Production of Sustainable Synthesis Products and Analysis of Hydrogen Model Regions.
Engage in discussions during the conference.

We look forward to exchanging ideas with you!

Series Production of Electrolyzer and Fuel Cell Membranes

MEA-Production: printing technologies — © Fraunhofer ISE / Dirk Mahler
At Fraunhofer ISE, different printing technologies are available to produce catalyst layers: screen printing, slot die coating, inkjet printing, flexographic and gravure printing.

Fraunhofer ISE offers its customers the investigation of different processes for the production of electrolysis and fuel cell MEAs from laboratory to industrial scale. The researchers have a deep understanding of process and ink development for various coating processes, including rheological characterization, surface characterization of catalyst layers and detection of defects. They are able to flexibly adapt manufacturing processes to different materials and surfaces to be coated.

At the Hydrogen Technology World Expo, we will demonstrate the design of membrane electrode assemblies (MEA) for electrolysis and mobile fuel cells that can be manufactured using screen printing or slot die processes with commercially available materials. The process parameters identified in the laboratory for the differently manufactured MEAs for PEM fuel cells and electrolyzers provide the basis for scaling up in roll-to-roll manufacturing. Learn how it is possible to achieve flexible catalyst-coated membrane (CCM) production and process development that can be adapted to different materials!

Optimized microporous transport layers for PEM electrolysis

Proton exchange membranes (PEM) are one of the most promising technologies for the production of green hydrogen by electrolysis. To reduce the material and manufacturing costs for PEM electrolyzers, Fraunhofer ISE is researching scalable production processes for catalyst-coated membranes (CCM).

At the Hydrogen Technology World Expo, we will present microporous transport layers (MPL), which have been produced for the first time in a scalable manner on standard industrial screen printing systems. The approx. 20 µm fine MPLs enable the use of catalyst layers with significantly reduced iridium loading (ultra-low loading), as they considerably improve catalyst binding and thus utilization. They also simplify the use of thinner membranes so that ohmic losses can be reduced.

Press Release

CO₂ Direct Air Capture

Direct Air Capture reactor prototype in process evaluation test rig at Fraunhofer ISE.

Fraunhofer ISE offers cutting-edge research services in Direct Air Capture (DAC), developing efficient and scalable CO₂ capture processes. Our researchers focus on characterizing adsorption materials, refining process efficiency, and conducting techno-economic and life cycle assessments (LCA) of DAC technologies.

At the Hydrogen Technology World Expo, we exhibit a DAC demonstrator capable of capturing up to 0.2 kg of CO₂ per day using Temperature-Swing Adsorption (TSA) or Temperature-Vacuum-Swing Adsorption (TVSA). This technology ensures desorption of CO₂ with high purities and relies on mass-produced, robust materials, heaters, and fans, which enhance cost efficiency and scalability.

The system features zeolite for CO₂ capture and silica gel for H₂O adsorption, while also allowing the implementation of new solid materials such as amine-coated adsorbers, Metal-Organic Frameworks (MOFs), and Molecular Sieves (MOR). With short adsorption/desorption cycles and rapid heating times, the system is highly dynamic and can adapt to changing weather conditions or electricity prices within minutes.

Designed to be completely independent, it requires only electricity for venting, heating, and vacuuming, making it ideal for remote installations where no additional fluids, waste heat, or fuels are available. Additionally, it can provide water for electrolysis or biological ecosystems in dry regions, making it a versatile solution for sustainable energy and environmental applications. An automated test rig at ISE enables parallelized adsorption-desorption cycling with controlled air humidities for air flows of up to 120 kg per day, allowing for the capture of more than one kg of CO₂ daily.

Power-to-X

Fraunhofer ISE offers a wide range of research services in the field of chemical energy storage. The researchers develop efficient PtX processes, conduct assessments of technology and potential, and provide support with customized catalysts. They are currently researching sustainable liquid fuels for aviation, as well as an innovative, sustainable power-to-ammonia process that increases the ammonia yield and reduces production costs. In addition, they have developed the patented INDIGO process, an efficient and compact method for producing renewable DME from hydrogen and CO₂, which represents an efficient and cost-effective process alternative and can also be implemented at locations with limited infrastructure.

At the Hydrogen Technology World Expo, Fraunhofer ISE’s PtX Cube displays different hydrogen-based energy carriers in terms of their relative energy density compared to non-pressurized and compressed hydrogen.

Hydrogen Infrastructure

Optimal placement and scaling of electrolyzers: Fraunhofer ISE identifies and analyzes hydrogen model regions through geographic information systems (GIS).

The scientists use geographical information systems (GIS) to locate and analyze hydrogen model regions. Using techno-economic analyses, they develop and evaluate customized solutions for the production of clean hydrogen from renewable energies, its efficient storage and demand-oriented distribution. They prepare feasibility analyses of hydrogen projects, calculations for the design and optimization of electrolyzers, output forecasts and life cycle analyses.

At the Hydrogen Technology World Expo, the 3D exhibit “Hydrogen Model Region” models a local, self-contained world with regional hydrogen production, distribution and storage and showcases the comprehensive expertise across the entire value chain of the department Hydrogen Technologies at Fraunhofer ISE.
