It is becoming increasingly clear that the growing demand for hydrogen can only be met with the safe transportation of this increasingly important energy carrier. Since the targeted sharp reduction in consumption of natural gas could simultaneously free up transport capacity in existing gas pipelines, sustainably produced H2 could be distributed via existing gas networks, which would also mitigate supply and consumption peaks. However, this type of H2 logistics depends on components that can extract H2 from the gas grid at the point of demand and fill an appropriate short-term storage facility. They must both filter highly efficiently and compress energy efficiently. The H2 filter and compressor system HylyPure developed by TU Wien combines both. For example, for hydrogen refueling stations or to supply stationary fuel cells for re-powering, a few stacks with several HylyPure membranes connected in parallel are used. The know-how and the design come, suitably for a concrete market segment, from the TU Vienna, for the production and the market development now at the HANNOVER MESSE 2022 industrial partners are searched.

The Viennese are also focusing on heat recycling for industry. According to the Vienna University of Technology, the potential of waste heat in industry that could be used corresponds to almost one third of the total energy consumption of industry. That's why a novel module for heat recycling developed by TU Wien - consisting of a heat exchanger, fine granules of low-cost solid material and an industrial reaction gas - is designed to help leverage this potential. According to the researchers, the module can be adapted to the needs of specific industrial sectors and operations. The outstanding results with lab-scale prototypes will provide the basis for this. The know-how is available together with state-of-the-art analysis and manufacturing apparatus at the Vienna University of Technology. There, a unique combination of methods for the exact determination of the storage capacity, material analysis as well as synthesis techniques on the one hand, and current process and production technology on the other hand, work together. This should enable the efficient adaptation of the basic module to desired applications as well as the dimensioning of optimized highly dynamic heat accumulators from a single source.
