Novel Catalysts for Ammonia Cracking and Synthesis

Bill DavidJosh MakepeaceThomas Wood

The most effective ammonia cracking catalysts are currently based on rare metals such as ruthenium and cobalt. While iron can efficiently crack ammonia at 600 °C, it is desirable to develop similarly inexpensive catalysts that are effective at lower temperatures between 350 °C and 500 °C. In this presentation, a new family of imide-based catalysts are described that crack ammonia around 400 °C to 550 °C. These materials do not behave as conventional surface-based catalysts and offer an affordable route for on-board cracking of ammonia for hydrogen fuel-cell cars. The operational parameters of a small 50W lab-based demonstrator will be…

Cracking ammonia

Bill DavidJosh MakepeaceHazel HunterThomas Wood

In this talk, I will discuss our latest research in developing novel ammonia cracking catalysts. While ammonia can be used directly as a fuel in high temperature fuel cells, internal combustion engines and gas turbine, the ability to crack ammonia affordably and effectively increases the range of possibilities for utilising ammonia as an energy vector. For example, the production of an ammonia-free hydrogen/nitrogen gas mixture permits the consideration of ammonia as an on-board hydrogen storage option for transportation. Furthermore, the ability to partly crack ammonia provides an increased flexibility for internal combustion engines. I will outline developments in our search…
