Funding project ‘HydrAPlas’: Sustainable production of green hydrogen from ammonia

The primary task of RKV (Rauschert Kloster Veilsdorf) in this project, which is funded by the BMWE (Federal Ministry for Economic Affairs and Energy), is the development and characterisation of ceramic membrane contactors for the extraction of ammonia (gaseous) from aqueous media in decentralised operation.

The R&D team based in Veilsdorf is contributing its expertise to the HydrAPlas project funded by the BMWE, together with six other project partners and four associated partners. The objectives of the three-year project (May 2025 to April 2028) are:

  • to improve the transportability of hydrogen by means of cost-effective and energy-efficient reconversion of the ammonia used as a hydrogen carrier.

  • Utilising ammonia from regionally produced waste materials for energy generation (decentralised hydrogen production) while reducing greenhouse gas emissions.

     

This is of national and international relevance against the backdrop of politically demanded reductions in greenhouse gas emissions coupled with rising energy demand, particularly in the industrial sector. To achieve this, innovative concepts are needed, such as the use of ammonia as a hydrogen carrier. At present, no large-scale processes have yet been established for the conversion of ammonia back into hydrogen in the energy sector. Known and used processes (e.g. cracking) can be optimised technically and economically due to high costs (energy/catalyst costs). In addition, there are a large number of regional sources whose potential for obtaining ammonia gas as a raw material for hydrogen production is currently not being exploited. For a conceptual outline of the overall project, see the figure.
