Within the project wind2hydrogen, which has also been submitted for financing from the e!MISSION.at program, a process chain for the production of hydrogen from regenerative surplus power and feeding it into the public gas grid will be developed. The hydrogen could be stored in the gas grid, delivered as a mixture with natural gas to customers, but also separated from the natural gas at the customer’s premises and delivered for use in the chemical industry or for automotive uses.

The project HylyPure aims to develop a membrane process in the laboratory in order to separate hydrogen from natural gas. Suitable membranes and sequences will be identified, flexibility of the process provided and a process control concept established. The influence of trace components in the gas stream on process performance and product quality will be studied.

In order to guarantee a high product quality, gas permeation will have to be supplemented by additional processes like adsorption or absorption. Several adsorbents will be checked for their suitability. After numerical simulation, the complete process will be established in the laboratory.

The project result will be a process that can be further refined in subsequent pilot tests.
