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 World Hydrogen 2026 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.

The scientists map, analyze and optimize the upgrading and construction of regional and global infrastructure and the full value chain of supply networks (from feedstock provision through hydrogen and syngas production, conversion and storage to transport) in geo-techno-economic terms. The cost-efficient, locally optimized hydrogen landscape that they develop avoids stranded assets and considers transport costs, renewable energy potential and offtake requirements. Building on a detailed data base, they calculate electricity costs for promising sites and derive the final costs of hydrogen and green molecules. They optimize synthesis and reforming processes and plants, incorporating material/energy integration and costs models. Leveraging advanced techno-economic assessments, They evaluate and optimize electrolysis systems and hydrogen-based infrastructure for performance and cost-effectiveness. Our LCA methodologies enable the comparison of processes and products under current as well as future regulatory frameworks.

At the World Hydrogen 2026 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.

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 World Hydrogen 2026, Fraunhofer ISE exhibits 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.
