The high-temperature electrolysis loop HTE on basis of a solid oxide electrolysis cell SOEC allows for tests of hydrogen production in co-generation with other high-temperature processes.

The processes, from which the heat is used, to produce water steam for the electrolysis process, are simulated by electrical heating. The heat transfer is realized via heat exchanger.

Heat recuperation is implemented as well form the cathode as from the anode side gas stream. The aim is to create a system as energetic efficient as possible. Variations of the system in certain limits regarding temperature, pressure, and different types of gases are possible to simulate other high-temperature processes, e.g. bio mass gasification, new gas turbine processes, etc.

With minor changes the infrastructure can also be operated in fuel cell mode.

• Experimental verification of co-generation of SOEC with other high-temperature processes (e.g. HTGR) for hydrogen production 
• Power of electrolyzer SOEC: 1 kW
• Number of heat exchangers: 5
