Solid State Ammonia Synthesis (SSAS)

NHThree LLC was formed to commercialize the SSAS technology for high-efficiency synthesis of ammonia from water, air and electricity.

If the electricity is from a renewable source, the ammonia produced represents an entirely green energy fuel-energy cycle. The SSAS approach promises to be more efficient and less capital costly than past approaches using water electrolysis.

8 responses to “NHThree, SSAS

  1. Some of NHthree presentations compare SSAS and Haber Bosch energy requirements. It is not clear whether electric power input is 3415 Btu/KWH or say 8000Btu as it would be if the power generation thermal efficiency was 45%. Clarify

  2. Current SSAS energy efficiency is estimated as 7500 kWh/ton of ammonia produced. The minimum (theoretical) amount of energy input for the reaction of water and nitrogen to form oxygen and ammonia is approximately 5300 kWh/ton of ammonia produced. This translates to ~70% estimated system efficiency.

  4. I would like to build a fuel cell powered by NH3. Do you have any plans that would enable this?

  5. Building a fuel cell from scratch is a very demanding endeavor, both in terms of skill and materials costs. The fastest solution is to buy an off-the-shelf commercial PEM fuel cell (e.g., http://www.horizonfuelcell.com/) for use with an in-line ammonia cracker and scrubber system (https://www.crystec.com/kllhyame.htm).

  6. Can we use AFC for direct conversion of NH3 to electricity?

  7. how much electricity would be generated by one metric ton of NH3?

  8. We welcome discussion
    on design development of hydrogen nitrogen ammonia systems
