Applications & advantages of SOECs
Indicatively, high temperature Solid Oxide Electrolysis can be implemented in a combined SOEC-SOFC system with a broad applications range. The conversion of steam and electrical energy into H2 and O2 is achieved electrochemically by using an electrolyser.
The produced hydrogen can be stored and used, in a subsequent stage, for the generation of electricity and heat by a fuel cell engine. Electrolysis was not used commercially to produce hydrogen, until 1902 by the Oerlikon Engineering Company, while the first commercially available high-pressure electrolyser (30 bar) was presented in 1951 by Lurgi.
