Green ammonia: hydrogen storage and energy carrier \u2013 from production to ship propulsion<\/h2>\n
\n

Researching and developing new energy conversion and storage technologies for a future energy system based on green ammonia is the focus of CAMPFIRE, an alliance funded by the Federal Ministry of Education and Research with more than 80 partners from industry and science. In addition to technical implementation, legal framework conditions and acceptance issues are also being considered.<\/strong><\/p>\n<\/div>\n

Green ammonia<\/b>\u00a0\u2013 produced from solar and wind energy \u2013 is suitable as a\u00a0carbon-free hydrogen storage medium<\/b>\u00a0for the international as well as domestic transport of renewable energy. The energy carrier can be split back into its components hydrogen and nitrogen by ammonia cracking.<\/p>\n

Within the framework of CAMPFIRE, ZBT is developing a\u00a0new ultra-fine cleaning technology<\/b>\u00a0for the separation of residual ammonia for the production of hydrogen suitable for refuelling. It is based on amine salt storage and a cost-effective membrane separation module. Laser welding and 3D printing are used in the production. In addition, ZBT is developing a\u00a0safety concept<\/b>\u00a0and ways to integrate and operate the purification system in a high-pressure hydrogen refuelling system.<\/p>\n

For the decentralised synthesis of ammonia, ZBT is supporting the development and construction of\u00a0scalable, microstructured Haber-Bosch reactors<\/b>\u00a0with novel catalysts. Dynamic process models are used to model the integration of the reactors in plants for ammonia production from regenerative energy sources. As a possible future alternative to the Haber-Bosch process, the ZBT is involved in the development of thin-film-based membrane electrode units for electrochemical\u00a0solid-state ammonia synthesis<\/b>\u00a0(SSAS) on a laboratory scale.<\/p>\n

Ammonia-powered engines and fuel cells<\/b>\u00a0can be used not only for propulsion and on-board power supply of recreational boats, inland waterway vessels and seagoing ships.\u00a0Decentralised power and heat supply<\/b>\u00a0on land is also a field of application. In order to be able to operate engines directly with ammonia, an ignition fuel must be mixed in, for example hydrogen. For this purpose, ZBT is developing ammonia cracker plants in several projects to provide a hydrogen-rich gas mixture for ammonia engines with outputs between 15 kW and 1 MW.<\/p>\n

For the investigation of innovative reactor concepts with new catalysts and materials for pressurised operation, short start-up times and high dynamics, a newly constructed\u00a0ammonia infrastructure and laboratory technology<\/b>\u00a0is available at ZBT. Stationary and dynamic models are being developed and validated in experiments for computer-aided component and plant development and for the automation of the cracker plants.<\/p>\n

In another CAMPFIRE sub-project of ZBT, a concept for an\u00a0ammonia-based propulsion and energy supply system for a cruise ship<\/b>\u00a0is being developed and optimised for the load profiles of representative Baltic Sea routes starting from Rostock Port. The entire energy conversion chain is covered by an ammonia cracker system in combination with different fuel cell technologies and buffer batteries for peak loads.\u00a0Machine learning approaches<\/b>\u00a0in combination with dynamic modelling of the energy supply system are used for the optimal selection and dimensioning of the components.<\/p>\n

CAMPFIRE is funded with around 50 million euros as part of the BMBF WIR! programme and the BMBF lead project TransHyDE. The ZBT is a founding partner and head of Strategy & Technology of CAMPFIRE and is working on theoretical and experimental tasks in several sub-projects in the various technology developments for the establishment of green ammonia.<\/p>\n
