    • Fraunhofer Institute for Microengineering and Microsystems IMM is developing ammonia-based systems for a mobile, decentralized energy supply in the infrastructure, transportation, and industry sectors.
    • Ammonia as alternative to hydrogen for storage and transport
    • Ammonia could play a decisive role in transition to climate-friendly alternatives

    Let’s delve into the potential of ammonia-based systems for climate-friendly energy supply, as highlighted by the research at the Fraunhofer Institute for Microengineering and Microsystems (IMM).

    1. Ammonia as a Hydrogen Carrier:
      • Ammonia (NH3) is gaining attention as an energy carrier due to its ability to store and transport hydrogen efficiently. Unlike compressed hydrogen, which requires high-pressure storage, ammonia can be liquefied at a moderate temperature of -33°C, enabling higher volumetric hydrogen content.
      • This means that a smaller volume of ammonia can transport the same amount of hydrogen compared to compressed hydrogen, making it more practical for large-scale transportation.
    2. Advantages Over Hydrogen:
      • The use of ammonia as a hydrogen carrier offers several advantages over hydrogen itself. Ammonia can be liquefied at lower pressures, making storage and transport more feasible.
      • Additionally, ammonia does not contain carbon oxides or methane, making it a cleaner alternative to fossil fuels and mitigating greenhouse gas emissions.
    3. Applications and Projects:
      • Spaltgas Project: In collaboration with partners, Fraunhofer IMM is developing a combustion technology for a gas mixture containing ammonia, hydrogen, and nitrogen. This “Spaltgas” can be used as an energy source, particularly in industrial processes like brick firing, leading to carbon dioxide-free manufacturing.
      • AMMONPAKTOR Project: Fraunhofer IMM has developed a cracking reactor technology to produce hydrogen from ammonia efficiently. The reactor achieves a high efficiency of 90% by utilizing off-gas from pressure swing adsorption (PSA) for energy.
      • ShipFC Project: Collaboration with European partners to develop ammonia-based fuel cell systems for maritime applications, addressing the challenge of reducing CO2 emissions in the shipping industry.
    4. Efficiency and Innovation:
      • Fraunhofer IMM’s AMMONPAKTOR reactor, financed by the State of Rhineland-Palatinate using ERDF funds, boasts high efficiency and compactness. The second-generation reactor, currently in production, achieves a throughput of 25 kg/hour of ammonia, producing 70 kilos of purified hydrogen per day.
      • The innovative technology of the AMMONPAKTOR reactor sets it apart as one of the most efficient and compact reactors internationally, offering significant advancements in hydrogen production from ammonia.
    5. Future Outlook:
      • Ammonia holds promise not only for land-based applications but also for maritime propulsion systems, where conventional fuels fall short in meeting CO2 reduction goals.
      • Projects like Spaltgas and ShipFC demonstrate the versatility and potential of ammonia-based solutions across various sectors, paving the way for a more sustainable energy future.
