Ammonia to hydrogen fueling station CF10_4
Project duration: 01.04.2022 to 30.03.2025
Aim of project:
The research project has the goal of developing a plant for the production of hydrogen suitable for refueling from green ammonia. Cost-effective fine purification technologies for the product gas optimization of NH3 crackers are thus an important key enabling technology for the dynamic conversion of the hydrogen carrier molecule in CAMPFIRE. For the production of high-purity hydrogen, an innovative, cost-effective membrane module based on CuPd membranes is being developed in the project. Novel manufacturing processes based on laser welding and 3‑D screen printing will be used for the module. Prior to membrane purification, a continuous adsorption/desorption process for the removal of trace amounts of NH3 is achieved based on novel salt reservoirs. The novel approach allows process-intensified and thus more cost-effective separation modules. The ultrafine purification system consisting of membrane module and salt storage tank will be integrated into a high-pressure H2 refueling system. A safety concept for the new refueling system will be developed for this purpose. The new developments will be operated in a demonstration refueling station of the associated partner Air Products. The high-pressure H2 refueling station will be supplied with ammonia and is designed to supply up to 15 public transport buses. With the determination of the costs for the supply of hydrogen and the derivation of a roadmap for the introduction of NH3-fueled H2 refueling stations in selected regions of Europe.
