High efficiency ammonia synthesis systems
Presentation

High efficiency ammonia synthesis systems

John Bøgild Hansen

Haldor Topsøe A/S has developed a new technology for generation of ammonia synthesis gas via Solid Oxide electrolysis, which eliminates an air separation unit and has 20-30 % lower power consumption than traditional electrolysis based processes. The concept will be demonstrated in a 50 kW unit along with test of ammonia as fuel for Solid Oxide Fuel Cells. The partners in the project are: Vestas, Ørsted, Energinet, Aarhus University and DTU, and it is sponsored by the Danish Energy Development Programme.

A Study on Electrochemical Ammonia Synthesis with Proton-Conducting Solid Oxide Electrolytic Cells

Ammonia has become one of the most important chemicals with its versatility since the Haber-Bosch process was invented. Recently, ammonia has been getting interests because of its possibility as a hydrogen carrier. Since ammonia has high energy density and carbon-free characteristics, using ammonia as a fuel of solid oxide fuel cells is advantageous. However, the Haber-Bosch process spends much electricity because of the high pressure condition, and the process consumes more than 1% of energy consumption worldwide. Therefore, the development of a new method for the ammonia production is necessary. In this study, solid oxide based electrolytic cells were fabricated…

Roadmap to All Electric Ammonia Plants

John Bøgild HansenPat Han

Haldor Topsøe A/S is a world leading supplier of technology and catalyst for the ammonia industry. It is also a developer of Solid Oxide Electrolyzer technology. A road map towards all electrical ammonia plants of the future has been worked out implementing at first steps hybrid natural gas based/classical electrolyzer technology and ultimately SOEC based plants without air separation units.

Solid Oxide Cell Enabled Ammonia Synthesis and Ammonia Based Power Production

John Bøgild Hansen

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…
