High-temperature electrolysis and co-electrolysis

Solid oxide electrolyser cells (SOECs) are high-temperature electrochemical energy conversion devices. They are capable of electrolysing water and carbon dioxide for hydrogen and carbon monoxide production. In this chapter, mathematical models are developed for SOEC for generation of hydrogen and carbon monoxide syngas, which can be further processed to produce various fuels or chemicals. The fuel-assisted SOECs are also modeled to reduce the consumption of electricity. The results demonstrate that the SOEC is a promising technology for efficient fuel generation using excess renewable power.
