Haldor Topsøe’s leading role as supplier of ammonia synthesis catalysts and technology is well known. The company has, however, also been active for decades in developing Solid Oxide Cell based stacks and systems.

The presentation will describe a novel, highly integrated process for ammonia synthesis based on Solid Oxide Electrolysis. The energy efficiency is very high due to ability of the SOEC to use steam generated from the synthesis reaction heat in the ammonia synthesis loop and the favorable thermodynamics of high temperature electrolysis.

Experimental results from hydrogen generation from steam using SOEC and power production from ammonia using Solid Oxide Cell in fuel cell mode will be presented and discussed in the framework of sustainable energy scenarios.
