Cleaning hydrogen: ZBT investigates new process<\/h1>\n
\n

Fuel cell-based mobility requires clean hydrogen. Within the NRW project Hy-Cleanup, ZBT together with Max-Planck-Institut f\u00fcr Kohlenforschung is investigating new materials for removal of impurities from hydrogen.<\/p>\n<\/div>\n

Hydrogen<\/b>\u00a0as a carbon-free energy carrier will play an important role as a fuel for future mobility. For the distribution of hydrogen, large parts of the existing\u00a0natural gas pipeline network<\/b>\u00a0are to be used and further expanded and extended, respectively.<\/p>\n<\/div>\n <\/div>\n

However, due to the long-term use of the pipelines for the transport of natural gas,\u00a0impurities<\/b>\u00a0are present in the pipelines, which lead to\u00a0contamination<\/b>\u00a0of the supplied hydrogen. Furthermore, impurities can also enter the hydrogen during hydrogen production, distribution or compression. However, fuel cells need\u00a0high-purity hydrogen<\/b>\u00a0to achieve their lifetime targets.<\/p>\n

Filter systems<\/b>\u00a0with high absorption rates and loading capacities can help to remove these and to comply with the limits defined in the international quality standards EN 17124:2022 and ISO 14687:2019. Preliminary investigations of the process to be developed in the Hy-Cleanup project showed that it has the potential to remove harmful species – especially sulphur compounds and carbon monoxide – from hydrogen to below the limits specified in the standards.<\/p>\n

The materials used had\u00a0high loading capacities<\/b>. They are based on substances developed by the Max-Planck-Institut f\u00fcr Kohlenforschung, which belong to the group of substances known as complex aluminium hydrides. Simulations based on the material reactivities show that these materials are suitable for adsorbing numerous contaminants – in addition to the already mentioned sulphur compounds and carbon monoxide already mentioned, also ammonia, formaldehyde, halogenated hydrocarbons or formic acid.<\/p>\n

The aim of the project is the development of a process that provides\u00a0high retention qualities<\/b>\u00a0and loading capacities for a large number of relevant impurities in hydrogen.<\/p>\n

ZBT elaborates the\u00a0application-related specifications<\/b>\u00a0for this project. Project focuses lie on the characterisation of the adsorber materials as well as the identification and validation of suitable process parameters. Finally, a\u00a0filter concept<\/b>\u00a0will be developed on the basis of the results obtained.<\/p>\n
